It complies with the HUD Model Manufactured Home Installation Standards. Please read all instructions and any other documents (includ- ing addendum pages and supplements) that may apply to the specific home prior to commencing site work or installation. This installation manual covers permits and site work through final inspection of the installation. It covers both single and multi -section homes installed over pier and anchor, load bearing crawl space walls and basement foundations. It contains instructions, including specifications and procedures, for the set and hookup of manufactured homes to be used as single- family dwellings. The importance of correct installation cannot be over emphasized. Correct installation is absolutely essential to home- owner satisfaction and the structural integrity of the home. All instructions must be followed to provide the customer with a safe, quality home. No manual can cover all circumstances that may exist for certain home designs or building sites. For questions, further clarification, or if you encounter conditions at the site for in the design of the home or its foundation not covered by this manual, please contact the manufacturer (see Resources, p. 1), a registered engineer, or registered architect. Supplemental addendum pages may be included with this manual. Supplements include requirements not covered in this manual or that supersede the manual instructions. Once the home installation is complete, leave this manual with the home. 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.

All systems must also meet one of the following: Systems or designs are manufactured and in 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. i 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 along the marriage line under support columns. These locations will be marked by the manufacturer. i 12'-0" 2'-0" 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 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 and�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. • Manufacturer's Installation Manual - June 2015 5 Getting Start This chapter covers a few steps that, .Y OF` re ken now, will avoid problems later in the installation process.

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. I • No home may be placed in an area with a higher roof load than that indicated on the data plate. (Example: la 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 art 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 or 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 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 anylspecial 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. PF dor 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.

The home is suitable for the installation of gutters and downspouts. When gutters and downspouts are installed, direct runoff away from thel 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 andl,become unleveled. • Fill must not contain large debris. This too will settle over time. • The soil must not be comprised of organic lays 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 varywith seasonal or climactic condi- tions. Consult a geologist or the LAHJ if you are unsure of the water table level. i 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 0 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. .A. PACIU:l.U-11Y"lLY- Manufacturer'is Installation Manual - June 2015 11 • The soil must not be a highly expansive type. Expansive soils can expand when they become saturated with'iwater, 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 LIVE 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 rnd/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 boitom 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. An engineer or building code official may be able to assist in classifying the soil found on the site. V&*OZZA 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 MANU�ACTUFlD �fAUTIIULIY' ABLE 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 design! g the support system. Keep a rec- ord of the soil -bearing capacity value; it will be use later to design the home's support system.

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 covered in this manual. STEP 1. DESIGN POINT LOAD SUPPORTS (p. 1'5) STEP 2. DESIGN FRAME SUPPORTS (Homes Without Perimeter Blocking) (p. 19) STEP 3.

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 Blockina Piers Door Piers Frame le Wall Piers Piers 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 ofithe required footing. Figure 7.

This will be indicated on the data plate and/or documents included with the home. If required, perimeter supports are only heeded on bearing walls. Bearing walls are those walls that support the ends of roof trusses or rafters (typically sidewalls and marriage walls but not end walls of main units or sidewalls of tag units). To minimize the number of required per supports, space them evenly between point load supports as shown in Figurel11 and Figure 12 (but not under spans).

A load -bearing perimeter wall foundation system uses a wall along the outer edge Of the home to support the fiome'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 a professional engineer or registered architect. 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 aroiund 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. STEP2. 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). V, /!

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. 26 1 Manufacturer's Installation Manual - June 2015 CHAMPION' When constructing pockets for an H-beam system, measure the beam depth and Level the wall. Make sure locate the pockets carefully. It is critical that when the home's frame rests on top of the foundation is level and the H-beam, the perimeter of the floor rests squarely on the extended foundation straight with no more than a wall. Leave room for a spacer on top of the wall pockets (to prevent corrosion, the 1/4 inch vertical variation steel beams must not be in direct contact with concrete). Leave at least one inch for over the entire foundation thermal expansion at the ends of the beams and maintain a minimum of two inches and no more than 1/8 inch of bearing area for the beams in the pockets (yielding a minimum pocket depth of vertical variation over any three inches). two -foot length. Bolt a pressure treated wood sill plate (minimum 2 x ) to the top of the foundation wall. Connect the home to the foundation according t the approved design. Re- Check for Plates. When us- ing an H-beam system, cess 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 hlul check and compensate for reinforcement plates that add thickness to the chas- sis beam at axle locations.

PREPARE FOR Before beginning the home set, comp • Confirm that the site is prom 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 hone 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 reporlt any damage or shortages to the manufacturer. • The ground moisture retarder nay be installed now or after the home is com- plete. See. Complete Exterio 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 wid 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 ways and other support points are within 1/4 inch of level overall and within 1/8 inch 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 the electrical bonding lugs on the front or rear outriggers. Reverse them to the 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 location (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&+0ZrZ1d 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 Manufacturer's Installation Manual - June 2015 1µ-1-1- u, I.- 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. • No one should be under the home while the jacks are being operated 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 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 (joint between flanges of twin I -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). — — — A_M___J 111:� 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.

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 remol ed 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 bad to the top of the cap. See Table 12 for pier construction requirements. i /, 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&Irzzj 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. 011 Manufacturer's Installation Manual - June 2015 CHAMPION' TABLE 11_ PIER MATERIAL MINIMUM SPECIFICATIONS mponent Specification • :.

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. W.W,Lh. C..h.r to use a water level' M C.5b 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 I -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 levelof 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. 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 un- less other contractual arrangements have been made. i0 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).

Do not re- move the temporary supports holding up the ceilings at major openings. i STEP 3. 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 the 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 for 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. V&AZZA 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.

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 handier location. See Table 20 to locate the appropriate figure. TABLE 20. UNDER FLOOR DUCT CONFIGURATIONS Furnace over trunk duct See Figure 5d See Figure 52 Furnace offset from trunk duct ; %ee Figure 51 y See Figure 53 Qualified personnel. Use on- ly qualified personnel to make crossover connections. Consult the LAHJ for licens- ing or any additional crosso- ver connection requirements. Access for service. Whenev- er possible maintain access to connection areas for fu- ture maintenance. Make tight connections. Permanent, durable, and tight crossover duct connec- tions are critical to the proper performance of the home. Leaky ducts can result in se- vere moisture problems in the home, discomfort from rooms not receiving the proper amount of condi- tioned air, and high utility bills from wasted heating and/or cooling energy.

The syste covered here uses earth (or ground) anchors and steel straps connected to the home's longitudinal steel beams and/orexterior walls. Stabilizer plates shall be used to prevent the anchor head from moving laterally in the ground. An anchoor, strap, and stabilizer plate together are referred to as a tie -down. Anchors can also be mounted in concr Ite 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.

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.

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 chassislat 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. i I &AZZ 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 structur- al 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 accepta- ble 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.

Chimney and combustion air intake duct installation r z 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.

INSTALL GROUND MOISTURE RETARDER If the space under the home is to be enclosedlwith skirting or other materials, a ground moisture retarder of a minimum six mil thick polyethylene sheeting or equivalent must be installed covering the ground under the home. Moisture retarders are not required in arid regions (less than 15 inches of rainfall annually) with dry soil conditions. If on - grade (surface) footings are used, install the ground moisture retarder prior to placing the footings, or install it around the footings after all other work under the home is com- plete. I i Install the ground moisture retarder as follows: 1. Apply sheeting. Unroll the ground moisture overlapping joints in the sheeting a minimum of 12 inches and covering the entire area under the home except for areas under recessed entries, decks,, and porches. 2. Weigh down. To keep the retarder in place, weigh it down with stones, concrete blocks, or other heavy, durable materials. 3. Repair tears. 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 with tape, adhesive or per manufacturer's installation instructions. i / A , Sealing bottom boards.

To design and install skirting, comply with the skirting manufacturer's instructions (if provided) and the following: l 1. Configure skirting. Run the skirting along the perimeter of the home's heated, conditioned space (Figure 96). Do not lenclose 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 water from 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 for frost heave when installing skirting in areas subject to frost. Provide ventilation.
