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 ou of compliance with the Manufactured Home Construction and Safety Standards. DISPLAY AND STORAGE OF THE F 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 12 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 aloni. the marriage line under support columns. These locations will be marked by the manufacturer. Figure 1. Supporting a home for display 1 Z'-0- 1 Z'-0- 12'-0- For all homes, place footings below each pier. Footings may be placed directly on the surface grade without excavation and may be ABS 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 (i.e. people 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 land pier at hitch end of home. Whether the home is being supported for display or storage the height of the home should be no higher than 36" as measured from the top of the ground to the bottom of the I-beam. In addition, it is extremely important that the roof/ridge vents are installed while the home is on display. Failure to install the roof/ridge vents may lead to significant damage to the roof and home.

STEP 1. LOCATE THE D TA PLATE Locate the data plate inside the home (rigure 2), typically inside a kitchen cabinet door or on a wall panel or door face near the electrical panel, utility room, or bedroom closet. �'�L'r'la7il. •• r The information on the data plate will b' 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 req,irements determined by the LAHJ. • No home may be located in a. higher wind zone than that indicated on the da- ta plate. (Example: a home designed for Wind Zone II cannot be placed in Wind Zone III.) • A home may be located in a I wer 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 - Shown as reference only. Actual data plate may vary. i I // 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. 6 Manufacturer's Installation Manual - June 2015 M ,�, �,.„..E FULLY- TARLF 1- WIND ZONF RY LOCALITY • areas except � being within U�Ilind Zone ll, or III All t those areas listed below as Zone Wind 11 • ...

CONFIRM ROOF LOAD ZONE From Table 3, identify the Roof Load Zone for the home. Verify that the home con- forms to the following rules. • No home may be placed in an area with a higher roof load than that indicated on the data plate. (Example: a home designed for the South (20 psf) Roof Load Zone cannot be placed in the Middle (30 psf) Roof Load Zone). • A home may be located in an area with a lower roof load than that indicated on the data plate. (Example: a home designed for the Middle (30 psf) Roof Load Zone may be placed in the South (20 psf) Roof Load Zone). • There are special high roof load areas (primarily in mountains) not shown on the map. Contact the LAHJ o� SAA for information about these areas. The home's data plate will indicate if the home has been designed for one of these high roof load areas. • Ramadas may be used in areas with roof live loads greater than 40 psf. Ramadas are to be self-supporting, except that any connection to the home must be for weatherproofing only. TABLE 3.

CHECK LOCAL CODES AND SECURE PERMITS Local regulations may set conditions for the siting aninstallation 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 constructiI n 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. 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.

PLAN SITE ACCESS Planning the route to the site is typically the responsibility of the retailer or transportation 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 compa I y 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 fill any holes and soft spots into which the transporter's wheels may sink. Avoid moving over steep changes in grade (20 degrees c r more). If required, provide for home storage and staging areas on the site. Plan the delivery and staging of home sections and maserials so that after all deliveries are complete, home sections and materials can be ccessed for use and installed in the appropriate sequence. Orient home sections so t ey. do not have to be rotated or excessively maneuvered during the installation pr?cess. Plan for temporary needs, such as dumpsters, portable toilets, crew park�ng, 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.

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. ' /z Fire separation.

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, includig roots from beneath footing loca- tions.

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 unleveled. • Fill must not contain large debris. This too will settle over time. • 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 belgreatly 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. i OFF 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/drainage can result in moisture -related problems such as mold, mildew, and erosion. Figure 4. (Left) Crown or keep soil flat under the home be- tween the outer beams to pre- vent water ponding Figure 5. (Right) Direct runoff away from the home 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. Manufacturer's Installation Manual - June 2015 11 • 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 un- leveled. 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 ()Mww.soils.usda.gov) and/or the LAHJ may have test results E nd/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing gapacity 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 bot om 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. Confrim that the rounded, result matches the soil. description on Table 4. Determine soil -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. Pn engineer or building code official may be able to assist in classifying the soil found on the site. i ' // 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 pen- etrometers. Pocket pene- trometers do not work on sand or gravel. Use to de- termine allowable pressure for these types of soils. If you encounter 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. 12 Manufacturer's Installation Manual - June 2015 1 MAN YIA IM."BAUTOW11' SOIL TYP Rock or hard pan (class 1) ;4,000 Sandy gravel and gravel; very dense and/or cemented sands; 2,000 course gravel/cobbles; preloaded silts, clays and coral (class 2) Sand`; silty sand; clayey sand; silty gravel;'medium dense course 1,500 sands; sandy gravel; very stiff silt, sand clays (class 3) Clay, sandy clay, silty clay, clayey silt (classes 4A and 413) 1,000 Uncompacted fill, peat, organic clays (class 5) ;;Professional testing required Note to table: No allowances made for overburden pressu�e, embedment depth, water table height, or settlement problems. • Use default capacity. Use an allowable pressure of 1,500 psf, unless site - specific information requires the use of lovyer values based on soil classifica- tion and type according to Table 4. 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 rec- ord of the soil -bearing capacity value; it will be used later to design the home's support 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.

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-bearinb end walls). Note: Listed adjustable outriggers may be used to replace piers below sidewall exterior door openings less that 48". Adjustable outriggers may only be substi- tuted if local codes permit the use of these devices and they are installed ac- cording to the manufacturer's ir�stallation instructions. Adjustable outriggers shall not be substitutes for othei pier applications and must be removed prior to any home relocation. (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 (when home has perimeter blocking aP,d 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 nder each end as shown. (8) Perimeter piers required under front and rear of homes with front cross member and rear frame recessed over 9 inches. (9) Pier each end of walk -a -bay over 16 inches out from home.

PREPARE FOR Before beginning the home set, compl • Confirm that the site is propE the first section of the home (for single section homes this is the only sec - the following: cleared and graded (see Prepare the Site, p. 10.) • Ensure that the footings are in place and properly located. • Install any utilities that will be difficult to install (e.g. those below grade beneath the home) after the home is in place. • Secure or remove from the home and properly store all ship loose items (refer to shipping documents for items shipped with the home). • Inspect the home interior, exterior and all provided materials, appliances, and equipment. Immediately report any damage or shortages to the manufacturer. • The ground moisture retarder may be installed now or after the home is com- plete. See Complete Exterior Work, STEP 2. INSTALL GROUND MOISTURE RETARDER (p. 89) for requirement and then return here. For perimeter bearing wall foundations: • Check that the length and widl h of the home match with the foundation walls. • Check that the two main diagonal measurements of the foundation are equal. • Check that the foundation wall s and other support points are within 1/4 inch of level overall and within 1/8 inc of level within any four foot distance. • For multi -section homes, check that each pair of diagonal measurements for each portion of the foundation corresponding to a home section are equal. • For multi -section homes, find he electrical bonding lugs on the front or rear outriggers. Reverse them to tlje inside of the outrigger using star washers so they will be accessible after the home is placed on the foundation walls. • If using an H-beam system, remove the frame's shackle hanger if it will inter- fere with proper placement of the beam. STEP 2. ' POSITION HOME SECTION Position the home section in its final locution (if possible, move the heaviest section of the home into place first). Then place materials needed to construct support piers near their final locations under the home as determined in Install Footings, (p. 15). STEP 3. 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. V&'t*#ZZA Clearances under the home. After the home is leveled, the resulting dis- tance between the bottom of the entire chassis main frame beam and the ground must be no less than 12 inches. Utilize proper cribbing. Manufactured homes weigh several tons. -No one should be under the home (whether it is mov- ing or stationary) unless proper cribbing is in place (Figure 17). Failure to uti- lize proper cribbing may result in serious injury or death. Leveling during jacking. Keep the home's floor as level as possible during jacking. Twisting or warping the floor can dam- age the structure and finish- ing. Use as many jacks as necessary to keep the floor flat and level. 28 1 Manufacturer's Installation Manual - June 2015 f, JACKS If jacks are to be used, comply with all jacking safety precautions and the procedure below. Lifting the home with jacks involves potential r sks and must be done with ut- most care and caution. Failure to follow jacking warniigs and procedures may result in serious injury or death. Please read the Jacking Safe y Precautions before lifting the home with jacks. No one should be under the home while the Jacks are being, operated or while" the borne 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 sides in contact with the'ground. Leave the hitch connected' to the vehicle or other stabilizing. equipment; •� " Obey all OSHA regulations: " • Make sure adequate safety 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 aoint between flanges of twin) -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 %Z-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). — _1 —_)i(--_J 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 la t 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 f i et 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.

Place safety timbers under home behind axle area and under hitch. lMANUFACTURED ERAU11VU1W 1 Installation Manual - June 2015 29 ROLLER SYSTEMS When using a roller system, comply with the equipment manufacturer's directions and the following sequence: 1. 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. Tempo larily 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 guid • Position the home section(s) and crane (taking the boom reach into consider- ation) 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 structuIe. • Place straps under walls or posts, including temporary posts used to support the opening. Do not position li Ing 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 f 3rthest from the crane first so that subsequent section(s) need not be lifted over previously set sections. i 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 blockir1g 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. V&OZZA No one should be under the home while it is suspended. Never put your hands between the house and the perimeter walls and support beams V&1rZZ 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. Manufacturer's Installation Manual - June 2015 CHAMPION" TABLE 11.

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. We Lh. C.�.h.r to use a water level Ch..b Position level. Position the level such that it can reach all piers. 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 lev- el of the 1-beams. 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. Bleed air. Hold the valve below the level of the water container; open the valve to bleed out any air and close the valve. 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. 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 6. Complete the opposite side. Jack the other side of the section up and install piers following the instructions above.

COMPLETE HINGED ROOF If the home has a hinged roof that has been folded down for shipping, raise the roof using a crane or roof jacks following the procedure below: 1. Position lift points. Position thel roof lift points (jacks or crane lift points) following the jack manufacturer or crane operator instructions. Space roof lift points equally along the length of the roof with no more than five feet from the end of the roof to the first or last lift points. Use three lift points for a roof up to 48 feet long (exclud- ing overhangs), four lift points fori up to 60 feet, and five lift points for up to 72 feet. 2. Remove fasteners. Remove any temporary fasteners connecting the hinged por- tion of the roof to the vertical king posts. 3. Lift roof. Raise the roof to its intended height. A temporary slight overextension may be required during lifting. However, take care not to overextend the roof and damage the hinge. Raise the roof evenly in small increments, keeping it level throughout the entire process to prevent racking. Do not allow roofing paper and shingles to get caught in the hinge crease. Position roof jacks. Posi- tion jacks vertically to pre- vent the jack foot from kick- ing out or sliding. Caution during roof rais- ing. Do not enter the roof cavity during the raising procedure. Checklists for alternate construction. If the serial number (see the data plate or the chassis front cross member) has the letters "AC" in the serial number, then the Alternate Con- struction on -site check list supplied with the home must be completed and re- turned to the home manu- facturer in a timely manner.

The system covered here uses earth (or ground) anchors and steel straps connected to the home's longitudinal steel beams and/or a terior walls. Stabilizer plates shall be used to prevent the anchor head from moving laterally in the ground. An anchors 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 noticovered in this manual. STEP 1.

Spacing requirements will vary depending on the type o f home (single or multi -section), the slope of the roof, the width of the floor for each see tion, the sidewall height, I-beam spacing, and the height from the ground to the strap a ttachment point. Determine the values for the home. Using the table for the appropriate V,iind zone, determine the column and row that corresponds to the charac- teristics of the dome. The value on the tables is the maximum distance between an- chors.

If the anchor spacing selected in the appropriate anchor table (Table 22, Table 23 or Ta- ble 24 has an asterisk (") then use the far beam method. Otherwise, use the near beam method (Figure 72). Each method varies by wind one 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 additionifor 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. I • 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 afar beam and one to the sidewall of the home.

Anti - Scald valves have been in- stalled on all tubs, tub/showers and showers in the home. The valves are preset by the valve manu- facturer to about 105°F (41 °C). After the water lines have been flushed, the out- let temperature at each tub, tub/shower and shower must be tested to ensure that it does not exceed 120°F(49°C). Water should run for at least one minute on the hottest setting be- fore taking the temperature reading. Some customers may desire temperatures higher than 105°F (41 °C). Temperature may be ad- justed using the instructions provided with the valve. In no case should the temper- ature exceed 120°F (49°C) as this may result in serious bodily harm and/or death.

II STEP 1. REPAIR AND SEAL BOTjTOM BOARD Tears and openings in the bottom board can result from transportation or installation activities. Inspect for holes and gaps across the entire bottom board, especially areas around service penetrations, crossover connections, pipe and duct hangers, foundation elements, and the perimeter of the floor. Using approved materials appropriate for the type of repair, repair the bottom board wherever tdrn or loosened as follows: 1. Insulate. Replace any missing insulation prior to closure and repair of the bot- tom board, paying particular attention to insulation gaps that may have been created at P-traps. 2. Repair large openings.

Repair any large voids or tears in the retarder by patching with like material, maintaining a minimum 12 inch overlap, secured with tape or ad- hesive. Repair small voids and tears withl tape, adhesive or per manufacturer's installation instructions. / ' / A Sealing bottom boards. A con- tinuous and sealed bottom board is critical for home per- formance, energy efficiency, protection against moisture problems, prevention of pipe freezing, and protection against insects and rodents. Bottom board sealing meth- ods. Tapes shall never be used alone to repair a bottom board. Divergent staples or mastic must be used in tandem with tape to prevent future tear off. Fastening vinyl siding. Do not install fasteners directly into vi- nyl siding. Allow for siding ther- mal expansion by pre -drilling minimum 1/2 inch diameter fas- tener holes or fastening skirting to a ledger under the home (see Best Practice tip): Q)- Avoiding radon. For enclosed perimeter wall crawlspace foundations in areas where radon is com- monly found in the soil, continue the moisture re- tarder up the perimeter wall at least 12 inches, sealing the edges and between the seams with mastic. CHAMPION' Installation Manual - June 2015 :• STEP 3. INSTALL SKI Skirting is any structural or non-str site -built structures (see STEP 5. ( abut the home (such as porches, TABLE 28. SKIRTING MATERIALS G perimeter crawlspace enclosure. Complete .ETE SITE -BUILT STRUCTURES, p.92) that J garages, and steps) prior to installing skirting. FICAT.IONS Skirting must be of weather -resistant materials or provided with protection against weather deterioration at least equivalent to that provided by a coat- ing of zinc on steel of not, less than 0.30 oz per sq ft of surface coated. Skirting made from woodi or wood products and used within six inches of the ground needs to be � ade of materials naturally resistant to decay and termite infestation or pressure -treated. Ventilation openings must be,covered for their full height and width with a 'perforated '(1/4 inch maximum opening in anydimension) corrosion and weather -resistant covering that is designed to prevent the entry of rodents. In areas subject to freezing, the coverings for the ventilation openings must P P i permitting . p posi- have an o erable dam er,them to be in the open or closed tion depending on the weather. , To design and install skirting, comply with the skirting manufacturer's instructions (if provided) and the following: I 1. Configure skirting. Run the skirting along the perimeter of the home's heated, conditioned space (Figure 96). Do not enclose with skirting areas under recessed entries, porches, or decks (whether constructed as part of the home or added on site) unless skirting is of the fully vented type and installed so as to allow water to freely flow out from under the home. 2. Fasten skirting. Recess the skirting under the siding or trim and attach it to the home in a manner that prevents waterifrom being trapped between the siding or trim and the skirting. For wood, aluminum, or fiberglass skirting, install a skirt rail (lumber strip) under the floor inset at least 1-1/2 inches from the edge of the siding for attachment of the skirting. Allow fori frost heave when installing skirting in areas subject to frost. 1 3. Provide ventilation. Unless the skirting has integral ventilation openings that meet the following ventilation requirements, ;nstall equally sized ventilation openings on at least two opposite sides of the foundation. Size ventilation area to equal at least one square foot for each 150 square feet oi, under -floor area (or for each 1,500 square feet if a ground moisture retarder is ins ailed according to STEP 2. INSTALL GROUND MOISTURE RETARDER, P. 89). Place vents as high above the ground as practical. 4. Install access. Provide an access opelping not less than 18 inches wide and 24 inches high and located so that any utility connections located under the home are accessible. 1 5. Extend vents, drains, and inlets. Run�appliance exhaust vents, combustion air in- lets, and air conditioner condensation drains through the skirting to the outside and terminate each as instructed in the sections of this manual corresponding to each appliance.
