First, review the entire manual, including the Introduction chapter. As you read it identify sections of the manual that you will need; identify other documents or information you will need; construct lists of tools and materials required for your particular installation; and make sure you have everything you need before starting work. After reviewing the entire manual, refer to the sequence of installation steps in the table below. Identify the pathway for your installation and follow the arrows downward. Select either Single Section Home or a Multi -Section Home and choose the col- umn corresponding to the home's foundation type, either Pier and Ground Anchor or Load -Bearing Perimeter Wall (see Definitions, p. 2). Then complete the work in each of the sections starting with Getting Started. If using an alternative (proprietary) foundation system, the installation process will change from that described in this manual. Consult the system manufacturer directions for instructions. See page 5 for alternative foundation system criteria.

Manufacturer's Installation Manual - October 2008 CHAMPION 6 IMPORTANT NOTICES • The home manufacturer is not responsible for installation or for the materials supplied by the set-up crew at the time of installation. The installer may be responsible for any deviations from the installation instructions of this manual. • To keep the home in compliance with its warranty, the home installation must follow the procedures described in this manual or other procedures approved by the manufacturer. Deviation from the instructions in this manual may void the home's warranty. Any alterations or changes to the home shall be approved by a registered engi- neer or registered architect and may still be subject to warranty violations. • When an installer does not provide support and anchorage in accordance with the approved manufacturer's in- stallation instructions, or encounters site conditions (such as areas that are subject to flood damage or high seismic risk) or other conditions that prevent the use of the instructions provided in this manual, the installer must obtain special site -specific instructions from the manufacturer or use a design approved by a registered engineer or registered architect. • The installer must possess a valid installation license as a manufactured home installer. • If the installer identifies failures of the home to comply with the Federal Manufactured Home Construction and Safety Standards (the HUD Code), the installer must notify the manufacturer and retailer. SAFETY There are potential hazards associated with the installation of a manufactured home. Home installers are licensed, and as experienced professionals, should recognize these hazards, be qualified to work with them, and be capable of providing safe work practices and equipment that minimize the risks of injury. Only qualified persons should install a manufactured home. As qualified professionals in the field of manufactured home installation, installers are the experts and must be aware of the hazards and conditions faced. Warnings are published throughout this manual as reminders. These reminders may not cover all hazards, all potential hazards, or all possible consequences of improper or unsafe installation practices. Construction crews should be trained in the skills required and be supervised by experienced personnel. Installers should regularly inspect work performed by crews and subcontractors. Obey OSHA regulations, particularly those related to home construction, such as Title 29 Code of Regulations Part 1926. For copies of OSHA regulations, call (202) 512-1800 or visit www.osha.00v on the web.

Manufacturer's Installation Manual - October 2008 CHAMPION6 ALTERNATIVE FOUNDATION SYSTEMS Champion approves the use of an alternative foundation system if first reviewed and accepted by the Local Authority Hav- ing Jurisdiction (LAHJ) and a recognized HUD Third Party Agency. All systems must also meet one of the following: • Systems or designs are manufactured and installed in accordance with their listings by a nationally recognized testing agency based on a nationally recognized testing protocol; or • System designs are prepared by a registered engineer or a registered architect or tested and certified by a regis- tered engineer or registered architect in accordance with acceptable engineering practice and are manufactured and installed so as not to take the home out of compliance with the Manufactured Home Construction and Safety Standards. DISPLAY AND STORAGE OF THE HOME WEATHER PROTECTION If the installation is not started immediately upon delivery of the home, the retailer and/or installer has the responsibility to ensure the exterior weather protection covering of marriage walls and the roof of homes with hinged roofs has not been damaged during shipment. Inspect the home immediately upon the delivery and frequently during storage. Promptly repair tears in the home closure materials to prevent damage from the elements. Inspect and repair roof shingles and siding as needed. SUPPORTING A HOME FOR DISPLAY When a new or used manufactured home is to be displayed at a retail location, temporarily block and support the home. Set up single -section homes with single block piers spaced no further apart than t2 feet o.c. beneath each I-beam. The tire and axle system may be used as one of these required supports, and the hitch jack may be used as another. Locate the first pier no further than two feet from the rear end of the home (Figure 1). Place additional piers along the perimeter on either side of openings greater than four feet (i.e. sliding glass doors, bay windows, etc.). For multi -section homes, locate additional piers along the marriage line under support columns. These locations will be marked by the manufacturer. Figure 1.Supporting a home for display For all homes, place footings below each pier. Footings may be placed directly on the surface grade without excavation and may be ASS pads, 2 x 10 by 16 inch long pressure treated lumber or 16" x 16" by 4 inch thick concrete pads. SUPPORTING A HOME FOR STORAGE To prevent damage to homes being stored but not on display (Lepeople shall not be permitted inside the home) for a pe- riod exceeding 30 days, locate piers below each I-beam no further than two feet from each end of the home and at the approximate center between the tire and axle system and pier at hitch end of home. CHAMPIOINI b Manufacturer's Installation Manual - October 2008 Getting Started This chapter covers a few steps that, taken now, will avoid problems later in the installation process. STEP 1. LOCATE THE DATA PLATE (p. 6) STEP 2. CONFIRM WIND ZONE (p. 6) STEP 3. CONFIRM THERMAL ZONE (p. 7) STEP 4. CONFIRM ROOF -LOAD ZONE (p. 8) STEP 5. CHECK LOCAL CODES AND SECURE PERMITS (p. 9) STEP 1. LOCATE THE DATA PLATE Locate the data plate inside the home (Figure 2), typically inside a kitchen cabinet door or on a wall panel or door face near the electrical panel, utility room, or bedroom closet. let The information on the data plate will be used to verify that the home was designed for the proper location. STEP 2. CONFIRM WIND ZONE From Table 1, identify the wind zone for the home. Verify that the home conforms to the following rules and any special requirements determined by the LAHJ. • No home may be located in a higher wind zone than that indicated on the data plate. (Example: a home designed for Wind Zone II cannot be placed in Wind Zone III.) • A home may be located in a lower wind zone than that indicated on the data plate. (Example: a home designed for Wind Zone II can be placed in either Wind Zone II or I.) • Homes located within 1,500 feet of the coastline in Wind Zones II and III must be designed to withstand exposure'D' conditions. This will be indicated on the data plate. If the home does not conform to these rules, contact the manufacturer immediately. Figure 2. Sample data plate Site appropriateness. If the site is not accessible, not appropriate for the planned support system or cannot be properly graded, notify the purchaser, the retailer and HUD, with the reasons why the site is unsuitable. Do not install the home until all issues are remedied.

C HAMPION II Manufacturer's Installation Manual- October 2008 Figure 91. Chimney and combustion air intake duct Installation Selecting the appropriate flue. Wood fireplaces use larger diameter flues than gas fireplaces. Make sure flue matches the appliance type. Gas fireplaces cannot burn wood because the flue is too small and smoke will back up Into the home. If wood fireplaces are con- verted to gas the flue will be too large resulting in ex- cessive heat loss through the chimney. Figure 92. Chimney clear- ance 1:b7 [LI PREPARE SMOKE ALARMS The home has several factory installed smoke alarms that are wired to a 120-volt cir- cuit. If the home was designed for placement on a basement, an additional alarm is provided for installation at a pre -wired location under the home. Connect the basement smoke alarm and test all alarms as follows: 1. Check circuit. Ensure that electrical power to the home is activated and that the smoke alarm circuit is on. 2. Remove batteries. Make sure backup batteries (if any) are removed from all smoke alarms. 3. Test alarms. Press the test button on each alarm sequentially. All alarms should sound simultaneously when the test button on any one smoke alarm is pressed. Replace (with the same brand as those installed elsewhere in the home) any alarms that do not sound and retest. 4. Replace batteries. After successful test, replace the backup batteries, dis- carding the protective tabs. PREPARE FIREPLACES Install chimneys, chimney flashing and roofing, fireplace combustion air inlets, and hearths according to the manufacturer's instructions and the procedures described be- low. CHIMNEYS Fireplace and wood stoves may require on -site installation of additional sections of ap- proved chimney pipe, a spark arrestor, and a rain cap assembly. Follow the manufac- turer's instructions and the procedures described below: 1. Remove coverings. Remove protective materials covering the roof flashing and any foreign material from the installed part of the chimney. 2. Install chimney pipe. Assemble and seal the chimney per the fireplace or wood stove manufacturer's installation instructions and if there is a conflict be- tween the instructions and the figure, follow the instructions. To assure suffi- cient draft for proper operation, extend the chimney at least three feet above the highest point where it penetrates the roof and at least two feet higher than any surface within 10 feet of the chimney (Figure 92). Use additional sec- tion(s) of chimney pipe (not provided) if required by local code or if the site has obstructions within 10 feet of the chimney.

STEP 5. CHECK LOCAL CODES AND SECURE PERMITS Local regulations may set conditions for the siting and installation of a manufactured home. Consult the LAHJ, state manufactured housing association, and the state SAA (See Resources, p. 1) for the specific local requirements, including: • Building codes that may affect the construction of site built structures and infrastructure. • Local requirements regulating the installation of manufactured homes. • Setback requirements for property lines, streets, yards, and courts. • Fire separation distances. • Development covenants for the specific property. • The locations of flood hazard areas and any special foundation requirements for homes installed in those areas. • In some areas, building permits are required to install manufactured homes. Prior to making any alteration to the site and the home, contact the LAHJ to determine if plan approval and permits are required. CHAMPION 6 Manufacturer's Installation Manual - October 2008 zz Areas subject to flooding. The foundation specifica- tions contained in this manual are NOT intended to address flood loads. If the home is in the flood plain, consult a registered engineer. Prepare the Site 10 Prepare the Site A properly prepared site is critical to a good quality installation and the long term structural stability of the home. This chapter explains the process of planning the site, evaluating the soil, and preparing the site for construction of the home's support system. STEP 1. PLAN SITE ACCESS (p. 10) STEP 2.

DETERMINE GROUND ANCHOR HOLDING CAPACITY (p. 14) STEP 1. PLAN SITE ACCESS Planning the route to the site is typically the responsibility of the retailer or transporta- tion company. Whoever is responsible must secure state permits from the states through which the home will pass. In planning the route, avoid obstructions that might interfere with the passage of the home, such as low hanging wires and trees, low overpasses, and bridges not suitable for the load. Contact the utility company if wires need to be moved. Do not allow branches, bushes, or other foliage to scrape against the home as the home is moved to the site. Avoid ditches, berms, steep slopes, and soft ground. Identify and Till any holes and soft spots into which the transporter's wheels may sink. Avoid moving over steep changes in grade (20 degrees or more). If required, provide for home storage and staging areas on the site. Plan the delivery and staging of home sections and materials so that after all deliveries are complete, home sections and materials can be accessed for use and installed in the appropriate sequence. Orient home sections so they do not have to be rotated or excessively maneuvered during the installation process. Plan for temporary needs, such as dumpsters, portable toilets, crew parking, delivery vehicle drop-offs and concrete mixer deliveries. Before moving the manufactured home to the site, inform the LAHJ and make sure the site is prepared and utilities are available. STEP 2. DETERMINE HOME LOCATION AND LAYOUT The home location may have already been determined by others. If not, plan the home location and layout in compliance with the regulations researched in Getting Started, STEP 5. CHECK LOCAL CODES AND SECURE PERMITS (p. 9). Contact utilities for locations of existing infrastructure, such as underground cables, pipes, and electrical lines. When planning the site improvements, consider the following: The home location should be level. • Avoid contact with large trees, steep slopes, poorly drained areas, and poten- tial flood zones. • Preserve trees and shrubs for shade, visual screens, and windbreaks. • Plan the driveway, parking areas, septic, well, other structures, and utility lines. • Consider future additions, such as screen rooms, porches, and awnings. • Site the home away from natural water paths. FSOFF Site Preparation. The home manufacturer has no con- trol over the site planning and installation of the home unless the manufacturer is responsible for the home's installation. Final responsi- bility for site preparation, including soil stability and frost heave control, lies with the installer. An improperly prepared site may result in the denial of a foundation - related warranty claim. //, Fire separation. Comply with any LAHJ fire separa- tion requirements or the re- quirements NFPA 501A, 2003 edition (Chapter 6). Manufacturer's Installation Manual - October 2008 CHAMPION6 PREPARE CLOTHES DRYER DRYER VENTS If the home includes a clothes dryer, the components for ventilating the dryer are included with the home (but not necessarily installed) and a vent opening has been roughed in either in the wall or floor. (If a dryer is not installed, seal all dryer vent openings). Run the dryer vent to the outside through the exterior wall or through the floor to a point beyond the perimeter of the home, using materials approved by the clothes dryer manufac- turer (see Figure 90). Vent Below Floor Clampto Secured to n Plaaor Install Though skirting Install the vent as follows: Vent Though Exterior Wall 1. Remove temporary caps. Remove any temporary seals and duct caps from the vent rough openings. 2. Install ductwork. Install ductwork using clamps (do not use screws or other fasteners that penetrate into the duct) and support the duct with metal straps connected to the floor joists or chassis at two feet o.c. or less. Ensure duct connections are internally overlapped to prevent inhibiting the flow of air and thereby causing lint accumulation. 3. Install cap and damper. Install an approved dryer vent cap with damper on the exterior termination of the duct. If the vent terminates at skirting secure the cap to framing or skirting with sheet metal screws and seal edges with caulk or sealant. If the vent terminates through a wall, apply a bead of sealant to the back of the cap around the opening and secure with sheet metal screws to metal, hardboard or fiber cement siding or with wood screws to a mount block for vinyl siding. 4. Seal opening. Seal openings inside and outside of the home including at the floor, interior walls, siding and skirting (with caulk), and at the bottom board using foam, mastic and/or tape specially made for that purpose. GAS DRYERS If the home was not fitted for a gas dryer, installing one requires substantial alteration to the home. Gas supply piping and adequate venting must be provided as specified by the dryer manufacturer and installed by a trained professional. Do not cut major struc- tural elements to accommodate a gas dryer. CHAMPION6 Manufacturer's Installation Manual - October 2008 ! //, Venting exhaust systems. Exhaust vents must extend to the home's exterior through skirting. Termination of the dryer exhaust under- neath the home can cause condensation and moisture damage to the home. Lint and dust accumulation can ignite, causing a fire. The exhaust system must not contain reverse slope. Figure 90. Clothes dryer ventilation ductwork through floor (left) or exterior wall (right) Avoid damaging structural elements. Do not cut or otherwise damage struc- tural elements such as floor joists or wall studs for the installation of the dryer ex- haust system. Gas. Ventilation components that may be included with the home for an electric dryer may not be accept- able for gas dryers. Consult the gas dryer manufacturer instructions. ®Installing ducts. Keep ductwork straight and smooth as possible without excess slack. Slope it slightly downward towards the exterior to facilitate moisture drainage. M INSTALL EVAPORATIVE COOLER OPTION Install evaporative coolers (also known as swamp coolers) as follows: 1. Check suitability. Check the home's Comfort Cooling Certificate (may be included with the data plate) to confirm that the home is suitable for the installation of an evaporative cooler and if so, any equipment sizing guidance provided by the manu- facturer. Only install a roof mounted unit if the manufacturer has provided the home with a platform and electrical supply intended for this use. 2. Select equipment. Select a unit with a maximum blower capacity of 500 CFM. If the unit will be roof mounted, choose one with a maximum operational weight (in- cluding water) of 220 lbs. 3. Install. To install the unit, follow the manufacturer's instructions complying with the requirements of the cooler's listing, all applicable local jurisdiction regulations and the requirements in this manual, whichever is more restrictive. 4. Secure roof -mounted cooler. To eliminate potential leaks with roof -mounted cool- ers, route guy wires over the side of the home and attach them to roof truss edge rails, rather than the roof itself. Do not attach guy wires to roof vents, flues, or other items protruding from the roof. 5. Install air supply. For roof -mounted units, install ceiling discharge grills no closer than three feet from a smoke alarm. For ground -mounted units, install ducts below the bottom board, with the exception of vertical risers into registers. Follow all ap- plicable crossover duct installation instructions (Connect Crossovers, STEP 1. CONNECT DUCTS, p. 49) when installing an under floor duct system to make ducts airtight. 6. Seal penetrations. To prevent water and air leakage into the home, take the follow- ing steps: For roof mounted units, seal all fastener penetrations, roof penetrations and the boot connecting the cooler to the roof opening. For ground -mounted coolers seal the bottom board where it is penetrated by vertical risers using foam, mastic and/or tape specially made for that purpose. 7. Connect water supply. Connect the cooler to an external water supply and attach an overflow hose to the accumulation pan. Route overflow water away from the home. 8. Connect wiring. Using wire nuts, connect the wires from a junction box (Figure 89) to the cooler and replace the cover on the box. Install coolers rated at 16 AMPS on a 20 AMP circuit and coolers rated at 12 AMPS max on a 15 AMP max circuit. Use one junction box per cooler and the following color codes for assigning wires: • White = Neutral • Yellow = Pump • Black = Low Fan • Red = High Fan • Green = Ground Manufacturer's Installation Manual - October 2008 Figure 89. Roof mounted junction box CHAMPION 6 STEP 3. CLEAR AND GRADE THE SITE Trim overhanging foliage considering future growth, potential storms, swaying in wind and snow/ice-weighted branches. Remove organic material such as vegetation, wood, roots, twigs, dead branches, grass, and brush from directly under the home. Remove any debris that could become termite infested from the site and surrounding area. Re- move all other debris from the home location, including roots from beneath footing loca- tions. Properly dispose of all items. Crown the site (Figure 4) so that water will not accumulate or stand underneath the home. Also, slope away from the foundation for the first ten feet with a minimum slope of 1/2 inch per foot. Where property lines, walls, slopes, or other physical conditions prohibit this slope, provide the site with drains, swales, or grading to drain water away from the structure. Any fill required to grade the site should be inorganic "controlled fill" applied in a maximum of four inch layers, compacted between each layer to at least 90% of its maximum relative density. Direct runoff away from the site using ditches and berms (Figure 5). If the home will have skirting, start grading from two feet in from the edge of the home. Site drainage. Moisture un- der the home can result in structural damage to the floor system and other parts of the home. Failure to provide adequate slope/drainagecan result in moisture -related problems such as mold, mildew, and erosion. Figure 4. (Left) Crown the soil under the home to prevent P waterponding Figure 5. (Right) Direct runoff away from the home y y Anum Indicate direction of water flow. Grade the ground so that water under porches, decks, and recessed entries flows away from the home. If proper grading is not possible, use other methods such as a drain tile and automatic sump pump system to remove any water that may collect un- der the home. The home is suitable for the installation of gutters and downspouts. When gutters and downspouts are installed, direct runoff away from the home. STEP 4. DETERMINE SOIL CONDITIONS Examine the soil type under the proposed home location to make sure it is suitable for placement of a home. The design of the home's support system, including footing/pier spacing and size, will in part be determined by the bearing capacity of the soil, and ground anchors by the soil's withdrawal strength. The soil under every portion of the support system must meet the following criteria: • The soil must be firm and undisturbed (not previously excavated) or fill com- pacted to at least 90% of its maximum relative density. Uncompacted fill will set- tle over time, causing the home to shift and become unlevel. • Fill must not contain large debris. This too will settle overtime. • The soil must not be comprised of organic clays or peat. Organic material can decay, causing settlement, and also may harbor pests that can infest the home. • The water table must be below the lowest level of the planned support system/ foundation. A soil's bearing capacity can be greatly reduced when it is saturated with water. Note that water tables may vary with seasonal or climactic condi- tions. Consult a geologist or the LAHJ if you are unsure of the water table level. CHAMPION Manufacturer's Installation Manual - October 2008 ' zz Soil. Inadequate soil bearing capacity or a support system mismatched to the soil char- acteristics can result in ex- cessive or differential set- tlement of the home, which can cause the home to go out of level, resulting in jammed doors and windows, cracks in finishes and rup- tured plumbing connections. 11 12 • The soil must not be a highly expansive type. Expansive soils can expand when they become saturated with water, causing the home to shift and become unlevel. If soils are expansive, contact a registered engineer, or registered ar- chitect to assist with the design of the foundation system. STEP 5. DETERMINE SOIL -BEARING CAPACITY AND FROST LINE The soil under a home must be capable of withstanding the loads imposed by the weight of the home, its support system and furnishings, as well as any loads imposed by wind, snow, or other climactic conditions. SOIL -BEARING CAPACITY Determine the soil -bearing capacity in pounds per square foot (psf) before designing a support system. The higher the capacity (psf), the more weight the soil can hold without unduly compressing. As the soil -bearing capacity increases, footings can be reduced in size or spaced farther apart. Use one or more of the following methods to determine the site's soil bearing capacity: • Test the soil. Hire a registered geologist, registered engineer, or registered architect to determine the soil classification and maximum allowable soil bear- ing capacity by testing the soil in accordance with generally accepted engi- neering practice. • Obtain soil records. The local office of the U.S. Department of Agriculture's Natural Resources Conservation Service (www.soils.usda.gov) and/or the LAHJ may have test results and/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing capacity as follows: 1. Select a location that will be under a footing. 2. Clear an area of a minimum of one square foot at least four inches deep or to the depth of the bottom of the planned footing. 3. Using the instructions provided with the pocket penetrometer, take at least five readings. 4. Discard the high and low readings and average the remaining readings. Round this result down to the nearest soil -bearing value shown in the right column of Table 4. 5. Confirm that the rounded result matches the soil description on Table 4. • Determine soll-bearing value by visual examination. If one of the options above is not available, the values on Table 4 can be used to establish soil - bearing capacity by visual examination. This method provides lower capacity values than the options above. Accurate soil identification typically requires special training or expertise. An engineer or building code official may be able to assist in classifying the soil found on the site. ow Z Soil bearing capacity. Sup- port systems on soils with bearing capacities less than 1,000 psf must be designed by a registered engineer or registered architect and approved by the LAHJ. Limitations of pocket penetrometers. Pocket penelrometers do not work on sand or gravel. Use Table 4 to determine al- lowable pressure for these types of soils. If you en- counter a layer of gravel, test the soil under the gravel. Do not put the penetrometer on stones larger than its tip as this will provide an inaccurate reading. Manufacturer's Installation Manual - October 2008 CHAMPION 1 U I I Home 4. Connect wiring.

PREPARE VENTILATION SYSTEM Prepare the whole -house ventilation system according to the ventilation system manufac- turer's instructions. Confirm that any fresh air intake ducts extend to the exterior and do not draw air from the crawlspace under the home. Do not allow any fresh air ventilation intake ducts to become kinked or restricted, forming a trap (Figure 88). PREPARE FUEL -BURNING WATER HEATER The water heater discharge and drip pan drains should have been installed in Connect Utilities (p.75). In homes with direct -vent water heaters (that utilize gas, oil, or other combustion fuel), and where the water heater is not independently vented to the exterior through a grilled opening, provide combustion air from under the floor using pipe and cement acceptable to the appliance manufacturer or through the roof via a double -walled flue pipe. If pro- vided through the floor, run the air piping to the exterior of the home, with supports spaced every 3-1/2 feet o.c. or less. Terminate the pipe facing downward a minimum of 12 inches above the ground surface and provide a screen on the pipe vent cap. CHAMPION6 Manufacturer's Installation Manual - October 2008 Figure 87.

Prepare fuel -burning heating systems included with the home as follows: 1. Inspect for damage. Inspect the furnace and report any damage to the home manufacturer. 2. High altitude. If the home is located more than 2,000 feet above sea level or as indicated in the furnace manufacturer's instructions, derate gas furnaces 4% for each 1,000 feet above sea level. This work must be done by a qualified (and in some jurisdictions, licensed) technician. 3. Convert for LPG gas. If LPG gas (propane) will be used, convert the appliance from natural gas to LPG gas use. Conversion must be made by a qualified and (if required by the LAHJ) licensed technician. 4. Install Intake air pipe. Consult the appliance manufacturer's instructions for maximum allowable pipe run length, requirements for air dampers, locations relative to expected snow levels (check with the LAHJ for expected snow levels), acceptable materials, pipe supports, and pipe termination requirements. 5. Install flue. For combustion appliances, install the flue roof cap and stack as- sembly as described in PREPARE FIREPLACES, Chimneys (p.84). INSTALL REMOTE HEATING AND COOLING EQUIPMENT Install remote units in compliance with all heating and cooling equipment requirements in this chapter above and the following: 1. Locate connections to the home. Find the manufacturer -installed connectors, labels, or tags under the home indicating the required connection points for sup- ply and return air. If connectors are not provided nor location indicated, select a supply duct location such that there are approximately equal numbers of supply registers forward and rear of the connection point. Locate the return duct in the center of the home. 2. Install ducts. Install the appropriate supply and return ducts (not provided) be- tween the remote unit and the home (Figure 88) making connections according to the instructions for crossover ducts in Crossover Connections (p. 49). 3. Install dampers. If installing a remote cooling unit in a home with a factory in- stalled furnace, install dampers between the furnace and the home's air duct system, and between the remote unit and the home's air duct system to prevent warm air in heating mode from escaping to the remote cooling unit and vice versa.

Note that soil types may vary across a home site. In this case, the soil with the lowest bearing capacity should be assumed when designing the support system. Keep a re- cord of the soil -bearing capacity value; it will be used later to design the home's sup- port system. FROST LINE In climates subject to ground freezing, consult the LAHJ, a registered engineer, or reg- istered architect to determine the depth of the frost line. Figure 6 may be used as a guideline when there is no specific local determination. Keep a record of the frost depth; it will be used later to design the home's support system.

DETERMINE GROUND ANCHOR HOLDING CAPACITY When using auger -type ground anchors to tie down the home, first, use a torque probe to determine the anchor -holding strength of the soil on the site. Use a torque probe with a shaft of sufficient length to test the soil at the depth of the anchor helical plate. Augur the probe into the ground, and following the probe manufac- turer's instructions, take the torque wrench reading in the area where the anchors will be installed and at the depth of the anchor helix. If the soil varies in consistency across the site, then use the lowest reading. Based on this reading, consult the anchor manu- facturer's charts to select the anchor type(s).

Check suitability. Check the home's Comfort Cooling Certificate (may be in- cluded with the data plate) to confirm that the home is suitable for installation of central air. If so, note the air distribution system's rated duct capacity (BTU/hr), any equipment sizing guidance provided by the manufacturer and information provided to calculate the home's heat gain. 2. Select equipment. Select equipment with a rated heating capacity (BTU/hr) not exceeding the maximum indicated on the home's data plate and a rated cooling capacity sized in accordance with Chapter 28'of the 1997 ASHRAE Handbook of Fundamentals or ACCA Manual J, Residential Cooling Load, 8th edition. Informa- tion needed to calculate the home's heat gain can be found on the home's comfort cooling certificate. Choose equipment with a minimum circuit amperage (found on the equipment rating plate) no greater than the branch circuit rating of the exterior air conditioning receptacle (indicated on the adjacent tag), if present. 3. Install A -coil. When installing a cooling A -coil in a down -flow furnace that incorpo- rates a fresh air intake duct, position the duct in the furnace cavity according to the furnace manufacturer's instructions (Figure 86). For electric down -flow fur- naces, trim the ventilation duct as needed to allow installation of the A -coil and secure the duct to the wall of the compartment or to the top of the A -coil. Do not restrict the flex duct opening; allow the duct insulation to contact the A -coil, or al- low the duct to become kinked, restricted, or configured to form a trap. CHAMPION6 Manufacturer's Installation Manual- October 2008 i Zz Use listed appliances. All appli- cable appliances must be listed or certified by a nationally recognized testing agency for the application for which the unit is intended and installed in accordance with the terms of its listing or certification. Properly sizing equipment. Oversized cooling equipment can lower energy efficiency, reduce comfort, shorten equipment life, and may cause moisture prob- lems in the home (including po- tentially damaging the home's structure). Sizing guidance is pro- vided by the Manufactured Hous- ing Research Alliance Cooling Equipment Sizing Guidelines available at www.mhrahome.orc. I& Entire system test (with appliances) 1. Close appliances. Close all gas equipment controls and pilot light valves ac- cording to the individual gas equipment manufacturer's instructions. 2. Open valves. Assure that gas shut-off valves for all gas equipment are in the open position. 3. Attach gauge. Attach to the home's gas inlet a pressure gauge calibrated in ounces. 4. Pressurize system, Pressurize the system with compressed air to six to eight ounces (3/8 to 1/2 psi, or 10 to 14 inches of water column). 5. Check for leaks. Check for leaks as described above in step 4 of the Piping only test. Replace defective pipes or fittings with sound material and re -test. 6. Rinse connections. Thoroughly rinse all tested connections with water to remove leak detection fluid. GAS APPLIANCE START-UP Open the shut-off valve for each appliance and adjust the burners according to the appli- ance manufacturer's instructions. Verify that the furnace and water heater thermostats are operating properly and set them to the desired temperatures. STEP 4. CONNECT OIL SERVICE Homes that are equipped with oil burning furnaces must have oil supply piping installed and tested on site by a qualified professional in accordance with NFPA 31, Standard for the Installation of Oil Burning Equipment, 2001 or the requirements of the LAHJ, which- ever is more stringent. The home manufacturer does not supply oil piping or tanks. OIL CONNECTION Consult the furnace manufacturer's instructions for proper pipe -sizing and installation procedures. Where piping is run through the bottom of the home, ensure all holes in the bottom board are sealed tight with foam, mastic, and/or tape specially made for that purpose and made rodent proof. When equipping the home with an oil storage tank, comply with the following: • Install the pipe with a gradual slope toward the fill end or drain plug (if so equipped) to facilitate pumping or draining of water and sludge. • Provide a readily accessible approved manual shut-off valve at the outlet, in- stalled to close against the supply. • Equip the tank with an approved oil filter or strainer located downstream from the tank shut-off valve. Use a filter or strainer containing a sump with a drain to trap water. • Equip under ground tanks with a filler neck extending one foot above grade and a minimum 1-1/4 inch diameter vent pipe extending at least two feet above grade, • Locate the tank to be accessible for service and inspection, and safe from fire and other hazards. • If the tank is located inside a compartment of the home, provide ventilation at the bottom of the compartment to permit diffusion of vapors. If the tank is fixed to the home, provide for filling and draining from the outside. • Insulate interior tanks from the structural members of the home. Provide tanks so installed with an outside fill and vent pipe and an approved liquid level gauge. • Install tanks that feed vaporizing type oil furnaces so that oil flows by gravity. To achieve efficient gravity flow, make sure that the bottom of the tank is at least 18 inches above the furnace oil control level. • Tanks for gun type oil furnaces (these furnaces include a fuel pump) may be installed above or below ground.

A footing and pier together (discussed in Set the Home) is referred to as a "support." A footing may also be designed to carry the load of multiple piers (often called "strip" footings). The design of strip footings is not cov- ered in this manual. STEP 1. DESIGN POINT LOAD SUPPORTS (p. 15) STEP 2. DESIGN FRAME SUPPORTS (Homes Without Perimeter Blocking) (p. 19) STEP 3. DESIGN FRAME AND PERIMETER SUPPORTS (Homes With Perimeter Blocking) (p.20) STEP 4. SELECT FOOTING MATERIALS (p. 22) STEP 5. SIZE FOOTINGS (p. 22) STEP 6. INSTALL FOOTINGS (p. 24) STEP I. DESIGN POINT LOAD SUPPORTS All homes will need supports, and therefore footings, under the frame, marriage line (for multi -section homes), exterior wall openings and other heavy point loads. The home manufacturer may have provided a blocking diagram (or tags, labels, paint or other markings under the home) indicating the required locations and/or loads for perime. ter, marriage line and/or frame supports specifically for this home. If so, the diagram or tags take precedence over the directions provided in this manual. Create a sketch of the home that includes the exterior walls, the frame I -beams and the marriage line(s), if a multi -section home. The sketch will be used in this chapter to locate each support, and note the size of the corresponding footing. Figure 7 is an example of such a support plan. Perimeter Blocking Piers Door Pin,< Tame Wall Piers ers As the location and load for each support is determined, note it on the sketch. When se- lecting locations for supports, keep in mind that increasing the spacing between supports will increase the load on that support and the size of the required footing. CHAMPIONi Manufacturer's Installation Manual - October 2008 Figure 7. Example of support plan 15 DETERMINE LOCATIONS Point loads exist where a bearing/structural weight is concentrated and transferred to the foundation at a specific point. Locate a support under each point load, including the fol- lowing examples: (1) Exterior doors on side walls at both sides of each door (blocking is not required at exterior doors on non -bearing end walls). (2) Other exterior wall openings four feet and greater at both sides of each opening (including multiple windows that total four feet wide or more without intermediate supports, even if individual windows are less than four feet). (3) Marriage line openings four feet or greater at both sides of each opening (where marriage line openings are greater than 10 feet, intermediate supports must be placed at maximum 10 feet on center). (4) Marriage line pier at corner of offset. (5) Load -bearing porch posts. (6) Under heavy (400 Ibs or greater) items, such as heavy furniture, waterbeds, fireplaces and large fish tanks. (7) Tags require 3 perimeter piers under each end as shown. (8) Perimeter piers required under front and rear of homes with front crossmember and rear frame recessed over 9 inches. (9) Pier each end of walk -a -bay over 16 inches out from home. Off Set Notes • Roof of offset section must have center peak • Maximum offset without center peak is 4 feet in Wind Zone I. • All other offsets need installation addendum. • Offset shall be tied down and piered as a single section for that portion of the home. Also, pier shall be placed at the inside corner where floors join (4), Mark the required point load support locations on the sketch. Supports are not required where the manufacturer has reinforced the floor (such as with additional outriggers or floor joists) and so noted in the documentation provided with the home.

Typical point -load support locations 1. Inspect vents. Assure that all exhaust vents on gas -fired equipment are se- curely connected and that roof jacks and stacks have not come loose during transit and they are properly installed. 2. Review appliance instructions. Review each appliance manufacturer's in- structions before the home is connected to the gas supply. Most gas appli- ances are typically configured to operate on natural gas. If the gas supply will be LPG, consult the appliance manufacturer's instructions to determine what changes need to be made. For homes located above 3,000 feet, appliances may require a different orifice. 3. Remove cap. Remove the protective cap from home inlet pipe and install a full flow shut-off valve at the supply inlet (Figure 85). 4. Install regulator. The gas piping system is designed for a pressure that is at least seven inches of water column (4 oz. per sq in or 0.25 psi) but not more than 14 inches of water column (8 oz, per sq in or 0.5 psi). If gas from any supply source exceeds, or could exceed this pressure, install a regulator if re- quired by the LAHJ. 5. Connect supply. Using matching threaded fittings, connect the gas supply to the inlet side of the shut-off valve. 6. Close valves. Close all valves at appliances prior to opening the main supply valve. Full FI( Valve (Suppl Others Source of Gas TESTING Test the gas piping system in the following two ways: 1) piping only and 2) entire sys- tem. Consult with the LAHJ for any additional testing or start-up requirements. Before testing is begun, the temperature of the ambient air and the piping should be approximately the same. Conduct the tests when and where air temperatures will re- main constant. Piping only test (all appliances isolated) 1. Isolate appliances. Isolate all appliances from the system by closing all ap- pliance shut-off valves. 2. Attach gauge. Attach to the home's gas inlet a mercury manometer or slope gauge calibrated in increments of not more than 1/10lb. 3. Pressurize system. Using an air compressor, pressurize the system with compressed air to three psi and isolate the pressure source from the system. 4. Monitor pressure. Monitor the pressure for at least 10 minutes. 5. Check for leaks. If pressure drops below three psi, check for leaks by apply- ing a non -corrosive, ammonia -free gas leak detection fluid to the joints at all valves, appliance connections, and crossover connections (do not use dish washing detergents, soap, or other household chemicals). If bubbles form, tighten the connection and recheck. 6. Repair leaks. If leaks persist, replace defective pipes or fittings with sound material and retest. 7. Release pressure. Release pressure and open all appliance shut-off valves. 8. Rinse connections. Thoroughly rinse all tested connections with water to remove leak detection fluid. Figure 85.

FREEZE PROTECTION FOR UNOCCUPIED HOMES If the home is to be left unheated in cold weather, protect water lines from freezing as follows: CALCULATE LOADS Use Table 5 and 5A to determine the loads on point -load supports. For each support, find the columns with the appropriate roof load and section width. Find the row(s) correspond- ing to the span (see Figure 9 for guidance on determining spans — if a support is shared by spans on both sides, add the respective loads together to arrive at the total load under that point). When ridge beam is continuous over support, multiply load by 1.25. The number in the columns under the "M" and "P" headings are the loads for supports along the marriage line and perimeter respectively (point loads in the center of a section, i.e. not along a marriage line or perimeter wall, require the load in the "P" column). Inter- polation for openings between those shown in the table is permitted. Note the required loads next to each point load support on the sketch. 5. LOAD ON — lbs. Figure 9.

Install water heater discharge drain. Inspect the drain opening on the water heater to ensure that it is clear of any obstruction. If the home is to be installed on a basement or enclosed crawlspace, install drain pipe connecting the dis- charge from the water heater temperature and pressure relief valve to the out- side or to a sump. 6. Install water heater drip pan drain. Assure that the drain for the water heater drip pan does not terminate under the home. Using the materials pro- vided and the accompanying instructions run a drain line from the water heater drip pan through the wall or floor to the exterior of the crawl space. Terminate the line between six and 24 inches above grade. (Figure 84). Make the termination point rodent proof. 7. Insulate. In areas subject to freezing temperatures, protect with insulation or heat tape pipes, valves and pressure reducers that are exposed to the outdoors; and pipes in water heater compartments with non -insulated doors. Connect heat tape to the electrical outlet under the home near the water supply inlet. Figure83. Water system connection ®Using check valves. Install a check valve on the water inlet to prevent water system drainage in the event of a loss of water pressure from the source. Such pressure loss could cause the water heater to drain, exposing the heating elements of electric water heaters caus- ing them to fail. Figure 84.

CONNECT WATER SERVICE CONNECTION To connect the home's water system to the water source, identify the water inlet lo- cated under the home (usually below the water heater compartment or utility room) and follow the procedure described below (refer to Figure 83): 1. Flush pipe. Flush field -installed water piping free of all debris prior to connec- tion to the home's water inlet. 2. Clean threads. Ensure that pipe threads are clean. 3. Install pressure -reducing valve. If the local water supply exceeds 80 psi in- stall a pressure -reducing valve. 4. Connect valve. Install a main shut-off valve between the water supply and the inlet on the home. Locate the riser for the shutoff valve underneath or ad- jacent to the home. Select a full flow gate or ball shutoff valve, or equivalent valve. To prevent the possibility of fresh water contamination install an anti - siphon valve on all field installed exterior faucets.

DESIGN FRAME SUPPORTS (Homes Without Perimeter Blocking) DETERMINE LOCATIONS All homes require regularly spaced supports along all main frame I -beams. Select spac- ing between supports and sketch them on the support plan. Keep in mind that frame sup- ports under homes with 8" deep 1-beams may be no more than eight feet apart. Those under homes with 10" or 12" deep 1-beams may be no more than 10 feet apart. Generally, greater distances between supports will require larger footings.

DESIGN FRAME AND PERIMETER SUPPORTS (Homes With Perimeter Blocking) DETERMINE LOCATIONS Depending on design and location, some homes require regularly spaced perimeter supports along all of the sidewalls and marriage walls in addition to frame supports. This will be indicated on the data plate and/or documents included with the home. If required, perimeter supports are only needed on bearing walls. Bearing walls are those walls that support the ends of roof trusses or rafters (typically sidewalls and mar- riage walls but not end walls of main units or sidewalls of tag units). To minimize the number of required perimeter supports, space them evenly between point load supports as shown in Figure 11 and Figure 12 (but not under spans). These figures identify typical support locations for homes requiring perimeter supports. Perimeter step 1) Piers CALCULATE LOADS Use Table 7 to determine the loads on frame and perimeter supports for homes requir- ing perimeter blocking. Find the column with the appropriate roof load and section width. Find the group of rows corresponding to the selected support spacing. The val- ues in the intersecting cells are the loads for the frame, perimeter, and marriage line supports respectively. Loads on supports of a given type (frame, perimeter, or marriage) can be assumed to be equal if support spacing is equal. However, if different support spacings are used then each support with a different spacing should be calculated separately. Note the location and load required of each support on the sketch.

ATTACH TAG UNITS (WIND ZONE I ONLY) After the main unit has been set on its foundation, install all tag units according to the following procedure: 1. Position and block the tag. Position the tag unit as close to the main unit as possible at its intended location. Use a hitch jack to obtain approximate level- ing and install pier supports according to Set the Home, STEP 2. POSITION HOME SECTION (p. 28). Determine whether the tag and main unit floors are designed to line up flush or are offset by a step and adjust the tag pier heights accordingly. 2. Level the unit. Using a water level (p.33), verify that the piers are level. The elevation of all points along the lower flange of the I-beam should be no more than 3/8 inches from the desired height and should not deviate more than 3/4 inches overall. 3. Connect floors. If the floor of the tag unit is level with main unit floor, connect the floors together as described in STEP 6. CONNECT FLOORS (p. 37). If the floors are offset, use the connection detail shown in Figure 37, fastening the angle iron to the tag unit with minimum 5/16" x 3" lag screws or #8 x 3" wood screws. Match fastener spacing and quantity to that used for the con- nection of the angle iron to the main unit. 4. Connect walls. Secure the tag unit walls to the main unit sidewall using #8 x 4" toe screws at 12 inches o.c. (see Figure 38). Once the wall connections are complete, finish the siding installation. Tag Unit Flwr Main Unit Rim Angle lion 5. Connect roofs. Connect the tag unit roof to the main unit roof using #10 x 5" screws, toe screwed at each main unit vertical structural member (stud or truss) location. See Figure 39 for flush roof connections and Figure 40 for roof connections with an offset greater than two inches. Roof connections with an offset less than two inches do not require screws. �Imbl FksM1F9 FM ��SN,gb Ovx JOM Mtl8 ub u rent mckNa y—�SNyb MYnU1 Tag lM Main Unt Melel F� /I (a rW Cwna ; qwf Wckig l t umi sore) reaw Faa�e,g VA // Piers under tag units.

Support duct. Support the crossover duct(s) above the ground using nylon or galvanized metal straps and saddles spaced every 48 inches o.c. or less. Choose straps at least 1/2 inch wider than the spacing of the metal spirals en- casing the crossover duct. Install the straps so they cannot slip between spi- rals. Secure metal straps with galvanized screws. ROOF CAVITY CROSSOVER DUCT For ducts installed in the roof cavity, follow the steps below: 1. Access duct. Access the crossover location through an access panel in the roof and remove any temporary shipping protection. 2. Join ducts. Using the provided flexible duct, join the distribution boxes in each section of the home as shown in Figure 54, cutting off any extra duct length to keep the duct as straight as possible. The duct is connected to one side of the home or connected to both distribution boxes and must be joined in the center with the provided connecter by inserting the inner liner of one duct into the other by at least three inches. 3. Fasten ducts. At each connection point between ducts and between ducts and distribution boxes or connectors, secure the inner duct liner with a nylon strap, apply mastic completely over the connection area, pull the duct insula- tion and outer liner over the connection area, and secure them with a second nylon strap. 4. Reinstall panel. Reinstall and secure the access panel. IN THE FLOOR CROSSOVER DUCT Where one or more crossover ducts are built into the home's floor system, connect them at their openings that run through the rim joists. Through the rim joist 1. With a through -the -rim joist design, the duct in each floor section terminates at an opening in the marriage line rim joist. Fixed through -the -rim crossovers employing a marriage line gasket such as in Figure 27 were completed in Complete Multi -Section Set, STEP 4. REPAIR OR INSTALL MARRIAGE LINE GASKET (p. 36) and require no additional work here. STEP 2. CONNECT ELECTRICAL CROSSOVERS Multi -section homes may have one or more electrical crossovers located in the wall(s) and/or floor(s) along the marriage line(s). JOINING WIRES Two types of connections may be present at these locations —snap connectors and junction boxes. Identify matching circuits if multiple circuits exist at a single crossover location. These will be coded for identification. Connect snap connectors according to the connector manufacturer's installation instructions, including fastener requirements. Connect wires in junction boxes as follows (Figure 55): Pull wires. Pull circuit wires into the junction box, sliding them through a romex con- nector and secure snugly. (Figure 55) Do not over -tighten. Avoid ground contact. In- stalled crossover ducts must not be in contact with the ground. Unobstructed airflow. Excess length, kinks and bends in the crossover duct will restrict air- flow and degrade the home's HVAC system performance. Figure 54. Duct crossover located in the roof cavity , Additional marriage Ime support. If the duct runs through the marriage line rim joist, a perimeter pier is required under the mar- riage wall at the crossover location unless otherwise noted on the manufac- turer's blocking plan or other supplemental docu- ments, or unless the home is constructed with a peri- meter support system. / 1 nZ Use qualified electrns.

Locate collars. Locate the metal crossover collars (or V-box) connected to the main trunk duct (or furnace) under the home and remove temporary ship- ping protection. 2. Install inner duct. Slide the crossover duct inner liner over the crossover col- lar/V-box as far as it will go. Temporarily fasten the inner liner in place with duct tape. Install a large nylon zip -tie over the inner liner just above the "ridge" around the crossover collarN-box. Apply mastic completely over inner liner and collarN-box (alternately, the mastic may be applied to the collarN-box prior to sliding the duct inner liner over it). 3. Connect duct insulation. Bring the duct insulation up over the zip -tie and above the home's bottom board into the floor cavity. Temporarily duct tape it against the base of the trunk ductfV-box. 4. Pull duct wrap. Pull the crossover duct outer wrap over the top of the insula- tion and temporarily secure it to the trunk duct/V-box with duct tape. 5. Install zip -tie. Feel for the nylon zip -tie that was installed over the inner liner. Place another nylon zip -tie just under the first one to permanently secure the crossover duct insulation and outer wrap. 6. Trim duct. Trim the crossover duct to length such that the installed duct will be straight with no kinks or unnecessary bends. 7. Connect other end. Follow the same procedure (steps 1 through 5) to con- nect the opposite end of the crossover duct and any other crossover ducts. 8. Seal joints. Seal the joints between the bottom board and the crossover duct with foam or mastic. Figure 50. Furnace over trunk duct, two home sec- tions Figure 51.

Between Step 5 and Step 6, drill three or more 1/16 inch holes an equal dis- tance around and just below the bottom edge of the nylon zip -tie. Install #12 pan head screws in these holes, through the flexible duct and into the metal crossover col- larN-box. The screw heads should be against the zip -tie. Cover exposed metal. Com- pletely cover all exposed metal connectors with insula- tion. Apply sealants and tapes only to surfaces that are dry and free of dust, dirt, and grease. 50 Manufacturer's Installation Manual - October 2008 CHAMPION6 STEP 10. REMOVE TEMPORARY ITEMS Once the home is properly supported and the marriage line connections are completed, remove the temporary ridge beam supports and wall/ceiling plates used to brace the ridge beam during shipment. Take care not to damage the ceiling. Remove and store or properly dispose of or recycle the hitch, axles, and wheels.

COMPLETE TAG UNIT ROOF (p. 46) STEP 3. COMPLETE SIDE WALLS (p. 48) STEP 1. COMPLETE ROOF RIDGE CLOSEUP For multi -section homes, the first step in completing the exterior is sealing the roof along the ridge line (Figure 41). For homes with asphalt shingles, follow the procedure below. For homes with metal or other roofing materials, follow the instructions that come with the roofing materials or provided as a supplement to this manual. Cap Shingle Underlayment Optional Metal (Wind Zone 2 4 � tion at Shingle installs- & 3 Only) lion at ridge Factory Installed Shingles Factory Installed Shingles Underlayment 1. Install underlayment (when sheathing at the ridge is installed on site). Make sure the roof sheathing is already installed (see Complete Multi -Section Set, STEP 7. CONNECT ROOF, p.39). Install 15# felt or equivalent continuously along the length of the ridge, covering all exposed sheathing and overlapping sheathing joints by at least five inches on each side. Fasten using 1" x 1" x 16 ga galvanized staples. For Wind Zones II and III, also apply a six inch wide strip of roofing cement along each side of ridge under the underlayment. 2. Install shingles. If shingles have been left off at the ridge line for site installa- tion, install them now using 1" x 1" x 16 ga galvanized staples or 12ga 1-1/4" long, 3/8" diameter head roof nails. For Wind Zone I, fasten at 5/8 inch above each tab cutout slot and one at each end of the shingle one inch in from the edge (four fasteners for a three -tab shingle) (Figure 42). For Wind Zones II and III, use two fasteners 5/8 inch above and on either side of the tab slots and one at each end of the shingle one inch in from the edge (six fasteners for a three -tab shingle). Do not fasten through the shingle tar line. ' // Weatherproofing. It is vitally important to close up the home quickly to protect the interior from damage due to inclement weather.

CONNECT DUCTS There are three main types of duct crossover connections. Based on the location of the duct, follow the installation steps on the page indicated below: • Under the floor (p. 49), • In the roof cavity (p. 51). • In floor, through -the -rim joist (p. 51) To prevent air leakage, seal all ductwork connections, including duct collars using one or more of the following materials: • Galvanized metal straps in combination with galvanized sheet metal screws. • For rigid air ducts and connectors, tape and mastics listed to UL 181A. • For flexible air ducts and connectors, tape and mastics listed to UL 181B. UNDER FLOOR FLEXIBLE CROSSOVER DUCT When heating or cooling equipment is installed in the home, the flexible crossover duct is provided by the manufacturer. In all cases the crossover duct must be listed for exte- rior use. There are four common configurations of under floor crossover ducts depending on the number of home sections and the furnace/air handler location. See Table 20 to locate the appropriate figure.

Method 2: Install two layers of roofing underlayment or equivalent over the joint between the main roof dormer and tag unit roof lapping the factory installed under- layment a minimum of six inches on each side and fully cemented at the laps. In- stall shingles per shingle manufacturer instructions and ridge cap/vent according to STEP 1. COMPLETE ROOF (p. 44). Valley line Along the bottom of the valley, shingles and one or more layers of roll roofing may need to be installed. If fastened to the roof at the factory, unroll the roofing, overlap the tag roof and trim the roofing to the roof edge. If shipped loose, install the roll roofing at the valley, lapping it under the factory installed roll roofing a minimum of 12 inches and fully cement the roofing at the lap. Complete shingles at the valley either by interweav- ing them or by trimming back approximately four inches from the valley line and fully cementing the exposed shingle edges. OFFSET ROOFS If there is a gap between the main unit dormer overhang and the tag unit roof of less than two inches, fold up the main unit dormer fascia, slide the underlayment and flash- ing from the tag unit roof behind the fascia, and bend the fascia back down and secure into sub -fascia with metal screws (Figure 48). CHAMPION Manufacturer's Installation Manual - October 2008 Figure 47. Tag unit flush roof connection 47 STEP 9. ATTACH TAG UNITS (WIND ZONE I ONLY) After the main unit has been set on its foundation, install all tag units according to the following procedure: 1. Position and block the tag. Position the tag unit as close to the main unit as possible at its intended location. Use a hitch jack to obtain approximate level- ing and install pier supports according to Set the Home, STEP 2. POSITION HOME SECTION (p. 28). Determine whether the tag and main unit floors are designed to line up flush or are offset by a step and adjust the tag pier heights accordingly. 2. Level the unit. Using a water level (p.33), verify that the piers are level. The elevation of all points along the lower flange of the 1-beam should be no more than 3/8 inches from the desired height and should not deviate more than 3/4 inches overall. 3. Connect floors. If the floor of the tag unit is level with main unit floor,, connect the floors together as described in STEP 6. CONNECT FLOORS (p. ). If the floors are offset, use the connection detail shown in Figure 37, fastening the angle iron to the tag unit with minimum 5/16" x 3" lag screws or #8 x 3" wood screws. Match fastener spacing and quantity to that used for the con- nection of the angle iron to the main unit. 4. Connect walls. Secure the tag unit walls to the main unit sidewall using #8 x 4" toe screws at 12 inches o.c. (see Figure 38). Once the wall connections are complete, finish the siding installation.

Choose straps at least 1/2 inch wider than the spacing of the metal spirals en- casing the crossover duct. Install the straps so they cannot slip between spi- rals. Secure metal straps with galvanized screws. ROOF CAVITY CROSSOVER DUCT For ducts installed in the roof cavity, follow the steps below: 1. Access duct. Access the crossover location through an access panel in the roof and remove any temporary shipping protection. 2. Join ducts. Using the provided flexible duct, join the distribution boxes in each section of the home as shown in Figure 54, cutting off any extra duct length to keep the duct as straight as possible. The duct is connected to one side of the home or connected to both distribution boxes and must be joined in the center with the provided connecter by inserting the inner liner of one duct into the other by at least three inches. 3. Fasten ducts. At each connection point between ducts and between ducts and distribution boxes or connectors, secure the inner duct liner with a nylon strap, apply mastic completely over the connection area, pull the duct insula- tion and outer liner over the connection area, and secure them with a second nylon strap. 4. Reinstall panel. Reinstall and secure the access panel.

POSITION ADDITIONAL HOME SECTIONS Follow this procedure to install additional home sections: 1. Remove obstructions. Remove protruding nails and staples or anything else that will keep the home sections from fitting together snugly. If present, cut the temporary ceiling and floor plates at the edges of marriage line openings tak- ing care not to damage ceiling or floor coverings or displace temporary mar- riage line support posts (these supports and the plates will be removed after the home sections have been structurally connected). 2. Complete crossovers. Before moving the two sections together, complete any crossover connections that require access from the open marriage line, including the attic duct connection (if present) and marriage wall interior elec- trical connections (see Connect Crossovers, p.49). 3. Position section. Position the section as closely as possible (ideally within six inches) and line up with the previously set section. If using a mechanical positioning system or crane, follow the system manufacturer's instructions or the crane operator's directions. 4. Construct piers. With the outside walls of the home aligned, construct the piers for the home section according to the instructions in Set the Home (p. 28) before continuing to the steps below. 5. Level section. Lower the section onto the outside piers first, inside piers last. Before releasing the mechanical positioning system, check interior doorways and other openings for misalignments that may cause problems during trim - out. The floors should be flush, level, and tight and the roof section should have little, if any, gap at the top of the marriage line. Use at least two come -a - longs to pull the sections snugly together and use the water level or other lev- eling device to set all piers and shims. 6. Shim gaps. Shim any gaps up to one inch between structural elements with dimensional lumber. If any gaps exceed one inch, re -position the home to eliminate such gaps. STEP 6. CONNECT FLOORS Make floor structural connections according to the method described below. Install toed fasteners through bottom board Install fasteners at approximately a 45 degree angle (+/- 5 degrees) from horizontal as shown in (Figure 29) using the fastener type, size, and spacing indicated on Table 13.

REPAIR OR INSTALL MARRIAGE LINE GASKET A continuous, non -porous gasket creating a permanent air barrier must be installed on at least one side of the marriage line; along the floor, end walls and ceiling (and mar- riage lines for any tag units). The manufacturer has provided a marriage line gasket ei- ther installed on the home or shipped loose. If installed, inspect the gasket and repair any gaps or tears. If not installed at the factory, install a continuous gasket between the home sections along the floor, end walls, and ceiling (Figure 28). For homes with through -the -rim crossover ducts (see Crossover Connections, p. 49) inspect and if necessary, repair gaskets around the rim joist duct openings using 3/4- inch thick fiberglass duct board or other material acceptable to the manufacturer. En- sure that duct openings are unobstructed (Figure 27). Figure 25. End wall comple- tion. See hinged roof truss installation addendum. / 1 /, Inspecting vents. Fuel fired heating appliance and fire- place vents that pass through a hinged roof must be completed and in- spected at the site prior to energizing the appliance or occupying the home.

The system covered here uses earth (or ground) anchors and steel straps connected to the home's longitudinal steel beams and/or exterior walls. Stabilizer plates shall be used to prevent the anchor head from moving laterally in the ground. An anchor, strap, and stabilizer plate together are referred to as a tie -down. Anchors can also be mounted in concrete footings when there is enough concrete mass (weight) to resist the lateral and upward forces. This type of system is not covered in this manual. STEP 1.

Manufacturer's Installation Manual - October 2008 CHAMPION! USING A WATER LEVEL A water level is a standard device for leveling the home. The level consists of the following components: • One container (five gallon bucket or one gallon jug). • 150 feet of 1/2 inch diameter plastic tubing. • Fittings for container to tubing. • Valve for terminal end of tubing. • Liquid for system: colored water in warm climates, windshield washing fluid in cold climates. HOW to use a Water level a. Position level. Position the level such that it can reach all piers. b. Place container. Place the container so that the fluid in the con- tainer is at the same level as the desired level of the top of the supports under the home, allowing for any bracing below the level of the I -beams. c. Uncoil tubing. Uncoil the tubing and fill with fluid, taking care not to introduce bubbles into the hose. Never allow anything to crimp or crush the tubing so as to impede the free flow of fluid. d. Bleed air. Hold the valve below the level of the water container; open the valve to bleed out any air and close the valve. e. Establish height. Locate the tubing adjacent to a pier that is set to the desired final height. Position the valve above the pier and open the valve. Move the water container up or down to where the water level is at the desired final height of the pier. Maintain the water container in that position and close the valve. f. Level piers. Move the tubing to the next pier. Hold the valve <' above the pier and open it. Set the pier height to the level of the ' water in the tubing and close the valve. Repeat this step until all piers are at the same level. 6. Complete the opposite side. Jack the other side of the section up and install piers following the instructions above. At the completion of this step, the sec- tion should be level from front to rear and from side to side. 7. Install perimeter and marriage line piers. Install perimeter piers and for multi -section homes, marriage line piers. Position marriage line piers to pro- vide equal bearing for both mating sections. 8. Remove running gear. Remove and store, recycle or properly dispose of the hitch, axles, and wheels. These items are the property of the homeowner unless other contractual arrangements have been made. CHAMPION 6 Manufacturer's Installation Manual - October 2008 Level the home. The home is adequately leveled if there is no more than 1/4 inch differ- ence between adjacent pier supports (frame or perime- ter) and the exterior doors and windows of the home do not bind and can be properly operated. Water level operation. To operate the water level Properly, both ends of the System must be open to the atmosphere and there must be approximately the same amount of fluid in the tubing at all times (within a few inches). 33 Mein ]�B .

Cap piers. Place a cap on hollow block piers to evenly distribute the structural load. Use caps the same length and width as the piers they rest upon. When using split caps on double -stacked block piers, install the caps with the long dimension perpendicular to the joint in the blocks below and to the main (- beam. 4. Install shims. Use shims to level the home and fill any gaps between the base of the I-beam and the top of the pier cap. Always use shims in pairs (Figure 19). Drive them in tightly so they do not occupy more than one inch of vertical space. When the space to be shimmed is greater than one inch and less than the minimum thickness of available caps or concrete blocks, use hardwood dimensional lumber (two inches maximum thickness) or 2" or 4" thick concrete block. For split caps, install shims and dimensional (um- ber/blocks over each individual cap. 5. Set up level. Ser up a water level with the fluid level at the desired height of the main piers. Carefully lower the side of the section down onto the leveled piers, adjusting the final height with shims. Figure 18. Frame pier construction i 1 Curing time of mortar. Where wet mortar is used to construct or level piers, al- low it to cure to at least 80% of strength capacity (usually requiring 96 hours) before setting the home. Figure 19.

Spacing requirements will vary depending on the type of home (single or multi -section), the slope of the roof, the width of the floor for each section, the sidewall height, I-beam spacing, and the height from the ground to the strap attachment point. Determine the values for the home. Using the table for the appropriate wind zone, determine the column and row that corresponds to the charac- teristics of the home. The value on the tables is the maximum distance between an- chors. Keep in mind that sidewall frame tie -downs must be located no more than two feet from each end wall. Figure 70.

Prepare footing surface. Make sure the footing surface upon which the pier sits is flat and smooth. Before placing the pier on the footing, clean dirt, rocks, or other material off the surface of the footing. For cast -in -place concrete foot- ings, if the footing surface is uneven, create a level, flat surface by placing a treated board on the footing and mortaring on the first block (or manufactured pier base), or by placing the first block (or manufactured pier base) on a layer of premix dry sand mortar. 2. Stack blocks. Stack concrete blocks with their hollow cells aligned vertically. When piers are constructed of blocks stacked side -by -side, orient each layer at right angles to the previous one (Figure 18) and plan blocks so that split caps will be perpendicular to the blocks they rest on and to the I-beam.

Establish staging area. Establish a staging area directly adjacent to one or both sides of the foundation. 2. Setup rollers. Set up the roller system according to the equipment manufac- turer's directions. 3. Fasten bump blocks. Temporarily fasten wooden bump blocks on the sill plates at the ends of the foundation to stop the home from rolling at the de- sired location. 4. Roll home. Roll the home into place over the foundation. 5. Remove bump blocks. Remove the blocks before installing the next section of a multi -section home. CRANES When using a crane, follow these guidelines: Position the home section(s) and crane (taking the boom reach into consid- eration) such that they do not have to be repositioned during the set. Use enough properly sized straps to maintain balance of the home and to prevent damage to the structure. • Place straps under walls or posts, including temporary posts used to support the opening. Do not position lifting straps under marriage wall openings. • Use a properly sized spreader bar to maintain a vertical lift, to avoid placing compression forces on the eaves and to reduce any tendency to slip. • Connect a rope to at least one point on the home so it can be controlled while aloft. • Make provisions to retrieve the straps/cables after the home is set. If using a cradle system, notch the sill plate where the straps will fall. For a sling sys- tem, notch and reinforce the home's rim joist to keep the strap from slipping and allow the strap to be removed after the home is set. • Always set the home section farthest from the crane first so that subsequent section(s) need not be lifted over previously set sections. STEP 4. CONSTRUCT PIERS For the side of the home section that is up on jacks, place piers on footings or pads fol- lowing the home manufacturer's blocking plan (or tags). If no plan was provided, use the support plan developed in Install Footings (p. 15). Start at one end of the home section and work toward the other noting the required pier material specifications and procedure described below. Construct piers so as to provide a stable foundation for the home using materials listed in the specifications box below and based on the location of the pier and its height as measured from the top of the footing or pad to the top of the cap. See Table 12 for pier construction requirements. Designing piers. Incorrect size, location or spacing of piers may result in serious structural damage to the home. Install piers at all re- quired locations. Failure to do so may lead to sagging floors, walls, and roofs, and could void the home's war- ranty. TABLE 23.

FJ, C s�0 AL ECG October 1, 2008 JACKS If jacks are to be used, comply with all jacking safety precautions and the procedure below. Lifting the home with jacks involves potential risks and must be done with ut- most care and caution. Failure to follow jacking warnings and procedures may result in serious injury or death. Please read the Jacking Safety Precautions before lifting the home with jacks. JACKING SAFETY PRECAUTIONS • No one should be under the home's I -beams while the jacks are being oper- ated or while the home is supported only on the jacks. • Use jacks only for raising the home. Do not rely on the jacks to support the home. • If possible, raise the home only on one side so that the other side is in contact with the ground. Leave the hitch connected to the vehicle or other stabilizing equipment. • Obey all OSHA regulations. • Make sure adequate safely cribbing (Figure 17) is in place whenever the home is placed on jacks. • Use a minimum of two commercial quality jacks, each with a rating of at least 12 tons. • Jack only on the main chassis I-beam, centering jacks directly under the beam. • Do not jack on a seam Qoint between flanges of twin 1-beams). • To distribute the concentrated loads from jacks to I-beam, place a minimum 3/8-inch thick steel plate, a C-channel, a 1 %,-inch thick hardwood block or a commercial jacking plate, between the main chassis I-beam and the jack head. • Locate the jack base on firm ground. Never jack on freshly disturbed soil or where an underground sewer pipe may be located. • Use a firm support under the jack base to prevent tipping or settling of the jack. A minimum 16" x 16" or larger wood or rigid fiberglass pad is recommended. Never use concrete blocks as a support for a jack. Follow the jacking sequence outlined below to avoid overstressing structural members 1. Block wheels. Block the wheels so the house does not roll. 2. Install cribbing. Install safety cribbing (Figure 17). - -f'� V db \ v II 3. Level lengthwise. Locate one jack at the hitch and level the section length- wise (such that the front and rear of the section are at the same height). 4. Locate frame jacks. Place a minimum of one jack just forward of the first spring hanger and another just behind the last spring hanger of the I-beam on the side of the home that is lowest (making sure not to place jacks where the piers will go). Place jacks no more than 20 feet apart and no more than 20 feet from each end of the I-beam. 5. Lift the home. Operating the jacks simultaneously (or sequentially in very small increments), lift the home section until it is slightly higher than the final desired pier height. Figure 17. Stack 4"x 6" by 5' long timbers as shown to form safety timbers. Place safety timbers under home behind axle area and under hitch. 64 Manufacturer's Installation Manual - October 2008 CHAMPIONI CHAMPION 6 Manufacturer's Installation Manual - October 2008 29 Set the Home This chapter describes the process of installing the first section of the home (for single section homes this is the only sec- tion) onto the foundation.

LIFT HOME There are three primary methods available to place the home on the foundation: jacking, rolling and craning. Jacks, often with roller systems, are typically used for pier and anchor foundations; roller systems are commonly used for crawlspace foundations with load - bearing perimeter walls; and cranes are most commonly used for basement foundations. SIDEWALL VERTICAL ANCHORS Homes designed for Wind Zones II and III also require vertical tie -downs along the sidewalls. The vertical tie -down anchor straps (or brackets for connecting to the home) are factory installed and indicate the locations. Vertical and frame sidewall tie -downs shall connect to one double -headed anchor. Any factory -installed sidewall tie -down straps must be connected to a ground anchor regardless of the wind zone in which the home is placed. END WALL FRAME ANCHORS End wall frame tie -downs are especially important for homes that are wider and have higher roof pitches because those features increase the surface area exposed to wind loads at the ends of the home. Use Table 25 to determine the number of end wall frame anchors required at the each end of each home section. TABLE 25.

OFFSET UNIT ANCHORS Anchor same as single section home (Figure 8). STEP 2. DETERMINE TIE -DOWN CONFIGURATION There are two primary tie -down configurations: the near beam and the far beam methods. If the anchor spacing selected in the appropriate anchor table (Table 22, Table 23 or Table 24 has an asterisk (*) then use the far beam method. Otherwise, use the near beam method (Figure 72). Each method varies by wind zone as described below. • Near beam method. For all Wind Zones, connect an anchor strap from the an- chor head to the beam closest to the anchor. In addition for Wind Zones II and III, connect a vertical strap from the sidewall of the home to the anchor head us- ing a double -headed anchor. • Far beam method. For Wind Zone I connect anchor straps from the anchor head (using a double -headed anchor) to both of the home's main frame beams. For Wind Zones II and III connect one anchor strap from the anchor head (using a double -headed anchor) to the home's far beam and one to the sidewall of the home. 4 4 October 1, 2008 28 Manufacturer's Installation Manual - October 2008 CHAW10N.1 CHAMW10A Manufacturer's Installation Manual - October 2008 65 Near Beam Flow Frame Tie Doi poor Near Beam (0m111 Win Frame Zones ll and110 TieNvm VeN[al Sidanl 00'MaMlmum Vwh[al6ldewa'I Fa Beam name rcDwxn To Be TeDww'n (W1ntl Tie Green (W'mtl I Added When Near Beam Strad Ang@ Zone it and 111 Ground Level Zones ll and 111 Gramtllavel Exoewis 60'AS In01[etod By V) On 0nri y OMy) n nn[n6r Chada) -SIaNI¢er Plaw Oreund Anchor Plate STEP 3.

Select a shaft diameter sufficient to resist excessive torsion, "ring -off' (when the helix or anchor head separates from shaft) or shaft splitting. Consult the anchor supplier for guidance. Review all of STEP 4. INSTALL ANCHORS (p. 66) and STEP 5. INSTALL STRAPS (p. 68) before making final anchor selections to determine when single -headed vs. double -headed anchors should be used. Follow the specifications in Table 26 when se- lecting stabilizing system components. ANCHOR Anchors must be tested and listed to resist a minimum ultimate load of 4,725 Ibs and a minimum allowable working load of 3,150 lbs or ultimate and corresponding working load limited by soil conditions and anchor length. The working load is the maximum load the designer can use. Ground anchors must be provided with protection against weather deterioration and corrosion at least equivalent to that provided by a coating of zinc on steel of not less than 0.30 oz per sq it of surface coated. Straps must be minimum 1-1/4" x 0.035" zinc -coated (0.30 oz per sq it) steel strapping conforming to ASTM D3953-97, Type 1, Grade 1, Finish B with a minimum allowable working load capacity of 3,150 Ibs and a minimum ultimate load of 4,725 Ibs. Slit or cut edges of zinc -coated strapping do not need to be zinc coated. The size and type of stabilizer plate, required by the ground anchor manufacturer, will be specified in the anchor manufacturer's instructions. Stabilizer plates must be provided with protection against weather deterioration and corrosion at least equivalent to that provided by a coating of zinc on steel of not less than 0.30 oz per sq it of surface coated. Alternatively, ABS stabilizer plates may be used when listed and certi- fied for such use. (Minimum allowable working load of 2730lbs) STEP 4. INSTALL ANCHORS Before beginning anchor installation, check for obstructions under the home such as piers and frame members that may interfere with the tie down strapping. Check with utility companies to determine the location of underground utilities, such as electrical and phone lines, and water, sewer, and gas pipes that may be buried in potential an- chor locations. Also check for homeowner -installed wires and pipes, such as those connecting exterior lighting or sheds to the home. These must also be avoided. FRAME ANCHORS Frame anchors shall be installed against a stabilizer plate. ®Grading area around anchors. Anchor heads should not rest in sunken spots. Grade the ground so that water does not collect around anchor heads, but runs away from the anchor and out from under the home. Do not bury anchor heads. When constructing pockets for an H-beam system, measure the beam depth and locate the pockets carefully. It is critical that when the home's frame rests on top of the H-beam, the perimeter of the floor rests squarely on the foundation wall sill plate (Figure 15). Leave room for a two-inch nominal, pressure treated wood spacer on top of the wall pockets (to prevent corrosion, the steel beams must not be in direct contact with concrete). Leave at least one inch for thermal expansion at the ends of the beams and maintain a minimum of two inches of bearing area for the beams in the pockets (yielding a minimum pocket depth of three inches). Bolt a pressure treated wood sill plate (minimum 2 x 6) to the top of the foundation wall. If the home's siding cannot be nailed through, use a 2 x 10 sill plate that ex- tends into the foundation 1-1/4 inches (Figure 16). The home can then be con- nected to the foundation by fastening the sill plate into the floor joists from below. Connect the home to the foundation according to the approved design. Recess nuts into the sill plate and cut off the ends of bolts so they do not project above the sill plate and interfere with the placement of the home.

BACKFILL AND GRADE Backfill against the foundation wall to the height of the damp proofing. Take care to not damage the drainage system. Grade the fill as per Prepare the Site (p. 10). Level the wall. Make sure the foundation is level and straight with no more than a 1/4 inch vertical variation over the entire foundation and no more than 1/8 inch vertical variation over any two -foot length. Check for Plates. When us- ing an H-beam system, check and compensate for reinforcement plates that add thickness to the chas- sis beam at axle locations. Figure 15.

A load -bearing perimeter wall foundation system uses a wall along the outer edge of the home to support the home's outside walls. This perimeter support works with interior supports such as piers, columns, and cross beams that support the home's frame and, if multi -section, marriage line. STEP 1.

OBTAIN A FOUNDATION DESIGN If a load -bearing perimeter wall foundation design has not been provided by the home manufacturer, it is the responsibility of the retailer and/or home owner to provide a de- sign approved by an engineer or architect, licensed in the state where the home will be installed. The approved design must comply with the LAHJ regulations for foundation design, waterproofing, and drainage, and the following: • The foundation perimeter bearing wall must be supported with a concrete slab or continuous strip footing around the perimeter of the home. Interior piers must be supported by a slab or footings. If footings are used under interior piers, they may be designed as in Install Footings, p. 15. • Slabs must extend to the edges of the home. Footings and slabs must be protected from the effects of frost heave by ex- tending the footings to or below the frost line or by using a frost protected shallow foundation design. STEP 2. EXCAVATE Excavate for the foundation, properly disposing of the earth that is not needed for backfill or site -grading purposes. STEP 3. CONSTRUCT THE FOOTINGS OR SLAB Construct the foundation according to the approved design, including the perimeter foundation wall, drainage system, footing(s), and/or slab. STEP 4. CONSTRUCT THE PERIMETER WALL Unless the approved design requires otherwise, construct the perimeter wall with mor- tared and reinforced concrete blocks or reinforced poured -in -place concrete. Install re- inforcement according to the approved design or LAHJ. Install ventilation and access openings according to the approved design, or if not specified, according to the re- quirements in Complete Exterior Work, STEP 3 INSTALL SKIRTING (p. 90). /,/' Y*J1 VZ, Using engineered designs. This section is NOT in- tended to provide a com- plete design for a buildable foundation. A complete de- sign must be obtained that is suitable for the local area and sealed by a professional engineer or registered archi- tect, licensed in the state. Foundation ready home. Make sure that homes to be installed on a basement or a crawlspace have been or- dered with a recessed frame or as foundation -ready, where the frame is designed to avoid interference with the foundation wall. Checking the water table. For basements, check for a high water table. The water table may vary seasonally or based on weather conditions. A ge- ologist can perform an algae test to determine the water table level. The foundation design must account for a high water table. Sidewall Frame Tie -Down Strap Ground Anchor with Stabilizer Plate Stabilizer Plate Configuration Stabilizer plate configurations Figure 73 are suitable for homes in all wind zones. An- chors may be installed after the home is set. A stabilizer device, typically an ASS or metal plate, is used to prevent the top of the anchor from slicing through the soil when the load is applied. Stabilizer plates are available in a variety of widths. Choose the widest plate that can be driven into the soil to maximize resistance to movement. The LAHJ may have stabilizer plate requirements. Install anchors with stabilizer plates as follows: 1. Locate anchor. Select a location for the anchor under the home but within four inches of the exterior wall Figure 74. Avoid locations that will interfere with skirting. 2 2� [-Beam 2. Install anchor. To assure that the anchor attachment point will end up at the stabilizer plate, start the anchor insertion approximately 12 inches back from the desired location if using a 48 inch long anchor, or approximately 16 inches if using a 60 inch long anchor. Install the anchor at about 15 degrees off verti- cal, with the head tilted away from the home. Install the anchor to a depth of approximately one half its length. 3. Drive stabilizer plate. Drive the stabilizer plate into the ground to its full depth at the point determined in Step 1. 4. Complete anchor installation. Screw the anchor the rest of the way into the ground. The finished anchor must be installed to its full depth. VERTICAL ANCHORS To install vertical anchors, screw the anchor into the ground directly under the strap at- tachment point on the home until the bottom of the anchor head is flush with the ground or no more than one inch above grade.

INSTALL STRAPS Follow the instructions below to connect straps from the home to sidewall frame, end wall frame and vertical anchors. Always protect straps at sharp corners including around I -beams with radius clips or other methods (Figure 75). Radius clips may be fabricated from 26ga (min) by 1 Y<- inch wide galvanized steel strap formed to fit around corners. 1 N\Da Longitudal Brack t Proiee[ Top and Bmtom d Beam It (V stmpisw.ppo Around Beam SPLICING STRAPS Splicing may be required when a pre-cut strap is of insufficient length. Splices in tie - down straps are not permitted in a configuration. Overlap straps by 12 inches, ap- plying one splice clip from above and the other from below; use a crimping tool to tightly seal the splice clips (Figure 76). Do not run any portion of the splice through an anchor head bolt. Apply Splice Clips In Direction of Arrows I Strap Approx. 12" NO SIDEWALL FRAME ANCHORS Install straps to sidewall frame anchors as follows: y' Splice Jot 'emiitted 1. Connect strap to home. Connect one end of the strap to the home connec- tion point using approved buckles or clips (swivel or hook clip preferred). OWrap strap around main beam OConnect hook totopof main beam and connect other end of strap to anchor head. Figure 75. Radius clips Figure 76. Tie -down strap splice Figure 77, Strap to beam connection // Strap to beam connection. Regardless of the strap sup- plier's recommendations, the strap must be connected to the top of the main beam to pre- vent damage to the structure. • If footings are rectangular, orient them so that the long side is perpendicular to the home's I-beam. • Place the bottom of footings on undisturbed soil or fill compacted to at least 90% of its maximum relative density. • In freezing climates protect footings from the effects of frost heave in accor- dance with any LAHJ requirements (see Prepare the Site, p. 10). Place the bottom of the footings below the frost line (insulated foundations and mono- lithic slabs are other frost protection options not covered in this manual). • Make sure the top surface of the footing is level, flat, and smooth. • In accordance with the American Concrete Institute publication ACI-308, maintain curing measures before construction or installation onto the concrete footing begins, until a minimum of 70% of the specified 28-day compressive strength has been achieved. The ACI recommended time to attain this level of strength is seven days for ASTM C150 Type 1 mixtures and 10 days for Type II mixtures. Full design live and dead loads may not be applied until the 28- day duration has elapsed for achieving full strength. ®Excavation. If excavation is required, mark the footing locations on the ground with stakes before beginning to dig.

STEP 6. INSTALL FOOTINGS Construct the footings as follows: Maintain the distance between adjacent piers to within 10% of the tabulated spacing and so the average distance between any adjacent spans is equal to or less than the tabulated spacing. Whenever possible, place point load supports directly under the required lo- cations. If plumbing, electrical, mechanical equipment interferes, place sup- ports no more than 6 inches in either direction of the support point. Recess perimeter blocking supports and perimeter point load supports no more than 10 inches from the edge of the floor with added support as shown in Figure 14. 4x4 Or 2-2x4'8 On Edge Together) Spanning Mn Floc Rim Plate 10" k From E Figure 13. Maximum footing extensions Placing Concrete anchors. If anchors will be placed in concrete, follow instructions in Install Stabilizing Sys- tem (p. 60) to determine anchor layout. Either place anchors immediately after the concrete has been poured or drill them in after the concrete has set. Figure 14. Perimeter supports 2. Connect strap to anchor. Connect the other end of the strap to the split bolt in the anchor. Leave enough strap length to be able to make at least three, but no more than five complete turns around the bolt before it becomes tight (approximately 2 1/2 inches per turn or 7 1/2 to 13 inches total). Fewer than three turns and the strap may not hold onto the bolt when force is applied. Conversely, more than five turns may not fit within the U-channel of the an- chor head. Follow the procedure outlined in Figure 78. OInsert the tension bolt into the anchor head and loosely attach the hex nut.

OOnce fully tensioned, align the square neck of the bolt with the square recess in the anchor head and tighten the hex nut. This will draw the two together and lock the system into final position. OUsing a 15116" socket or open end wrench, rotate clockwise, wrapping the strap around the tension but. If approved by the manufacturer, double head anchors maybe used for both diagonal and vertcal tie -down strap tensioning. Tension the diagonal tie -down stop first. Follow Steps 3 through 7 to Install straps to anclor head. 3. Pretension anchor. For anchors with stabilizer plates, pretension the anchor by pulling it up to the stabilizer plate using the strap and take-up bolt to move the anchor head. Continue pulling the strap until the plate moves a small amount (about 1/2 inch). This is called packing the plate and it will yield the strongest resistance (the bottom of the anchor head should be maximum 1/4 inch above the top of the stabilizer plate). END WALL FRAME ANCHORS Attach straps to the bracket welded by the manufacturer to the frame (Figure 79). If no brackets have been installed, use approved beam clamps designed specifically for this purpose, available from anchor suppliers. Connect straps to anchors following same procedure as for sidewall frame anchors. When more than one anchor per frame is re- quired, use swivel brackets and space anchors a minimum of 48 inches o.c. Figure 78. Procedure for connecting the strap to frame and anchor yzz Anchor head location. As the anchor is pulled up to meet the stabilizer plate, the head of the anchor will rise. In its final position, the bottom of the anchor head should be no more than 1/4 inch above the top of the stabilizer plate. 24 Manufacturer's Installation Manual - October 2008 CHAMPION6 CHAMPION6 Manufacturer's Installation Manual- October 2008 0 Figure 79.
