DISPLAY AND STORAGE OF THE HOh INDATION SYSTEMS system if first reviewed and accepted by the Local Authority Hav- :y Agency. All systems must also meet one of the following: ailed in accordance with their listings by a nationally recognized d testing protocol; or ngineer or a registered architect or tested and certified by a regis- ance with acceptable engineering practice and are manufactured compliance with the Manufactured Home Construction and Safety 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 f' m 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 along the marriage line under support columns. These locations will be marked by the manufacturer. Figure 1. Supporting a home for display 12'-0' 1 Z-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 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 ibeam. 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. AIAHUFACIUM BEAUTIFULLY- Manufacturer's InstalI lation Manual - June 2015 5 I Getting Started This chapter covers a few steps that,ltaken now, will avoid problems later in the installation process. 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 nearlthe electrical panel, utility room, or bedroom closet. L The information on the data plate i ill 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 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 lower wind zone than that indicated on the data plate. (Example: a home i 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 withstanld 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 , // 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. i. Manufacturer's Installation Manual - June 2015 CHAMPION' i TABLE 1.

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;n 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 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.

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. 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 I I 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.

DESIGN FRAME AND PERIMETER SUPPORTS (Homes With P l rimeter Blocking) DETERMINE LOCATIONS Depending on design and location, some homes require regularly spaced perimeter sup- ports 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 marriage 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 locatio�s for homes requiring perimeter supports.

Manufacturer's Installation Manual - June 2015 25 I Construct Foundation (FOR HOMES WITH LOAD -BEARING PERIMETER WALL) This chapter provides guidelines andl recommendations for the design and construction of a basement or crawlspace foundation using a load -bearing perimeter wall. 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.

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 Manufacturer's Installation Manual - June 2015 MANUfACTURlD .lAUTIFULIY� When constructing pockets for an H-beam system, measure the beam depth and locate the pockets carefully. It is critical that when the hlome's frame rests on top of the H-beam, the perimeter of the floor rests squarely orj the extended foundation wall. Leave room for a 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 maint6in 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. Connect the home to the foundation according to the approved design. Re- 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 home. 'I STEP 5.

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. I I 28 Manufacturer's Installation Manual - June 2015 ......I.H. DEAU11!1Y• 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. I • 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 (-beams). • To distribute the concentrated loads from jacks to I-beam, place a minimum M-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 1. Block wheels.

Place a minimum of one jack just forward of the first spring hanger and another just behind the last sprQ 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. i 5. Lift the home.

The level rnsists 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. WebrLhe Comber 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 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 tubingso 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. 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. 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). • MpN�,A�T�R[„e Manufacturer's Installation Manual - June 2015 33 Complete Mullti-Section Set This chapter covers the preparation and installation of additional home sections, including the structural connections be- tween units, raising and fastening hinged roofs, and fastening the home to a load -bearing perimeter wall foundation.

Do not re- move the temporary supports holding up the ceilings at major openings. 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 paints 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. Raiselthe 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.

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. 1 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 li , e. Use at least two come -a - longs to pull the sections snugly together and usel 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 I Make floor structural connections according to the method (described below.

After flashing is complete, install shingles per shingle manufacturer instructions and ridge cap/vent according to STEP 1. COMPLETE ROOF (p. 44). 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 a 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. I 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).

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, inch ding duct collars using one or more of the following materials: • Galvanized metal straps in combination with gal Ianized 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 181 B. 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 crossoverlduct 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. , TABLE 20. UNDER FLOOR DUCT CONFIGURATIONS Furnace over trunk duct See Figure 50 1 See Figure 52 Furnace offset from trunk duct q See Figure 51p See Figure 53 / A 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 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 an hor, 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.

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 theli 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 tfie tables is the maximum distance between an- chors. Keep in mind that sidewall frame tie -downs must beii located no more than two feet from each end wall and no closer than four feet to another tie -down.. i Figure 70.

The vertical tie -down anchor straps (or brackets for connecting to the home) are factory installed and indicate the locations. Vertical land 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.

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 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.

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 steelof not less than 0.30 oz per sq ft of surface coated. Straps must be minimum 1-1/4" x 0.035" zinc -coated (0.30 oz per sq ft) 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 ft of surface coated. Alternatively, ABS stabilizer plates may be used when listed and certi- fied for such use. (Minimum allowable working load of 2730 Ibs) 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. 66 1 Manufacturer's Installation Manual - June 2015 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 ABS 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 LAW 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. Max 'i12^ or ts^ �iInStablizer�1���� 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 tol 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.

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 '/- inch wide galvanized steel strap formed to fit around corners. Protect Top and Bottom of Beam ff—I-Beam Strap Is Wrapped Around Beam SPLICING STRAPS Splicing may be required when a preicut strap is of insufficient length. Splices in tie - down straps are not permitted in a 'Y1 configuration. Overlap straps by 12 inches, ap- plying one splice clip from above and the other from below; use a crimping tool to tight- ly seal the splice clips (Figure 76). Do not run any portion of the splice through an an- chor head bolt. SIDEWALL FRAME ANCHORS Install straps to sidewall frame anchors as follows: 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). Figure 75. Radius clips Figure 76. Tie -down strap splice iFigure 77.

If approved by the manufacturer, double head anchors maybe used for both diagonal and vertical tie -down strap tensioning. Tension the diagonal tie -down strap first. Follow Steps 3 through 7to install straps to anchorhead. I I 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 untill 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 strapsl!to anchors following same procedure as for sidewall frame anchors. When more thaln 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 i 1 / A 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. • M,,�,,�,�pEcee�orvour• Manufacturer's Installation Manual - June 2015 Main Beam Bracket Pier End Wall I Figure 79.

CONNECT ELECTRICAL SERVICE The home is designed for connection to an electrical wiring system rated at 120/240 volt AC. All electrical field work must be done by a licensed ed electrician or other person approved by the LAHJ. , FEEDER WIRE AND EQUIPMENT SIZES The current rating (in amperes) of the home can be found on the tag located on the outside next to the feeder or service entrance, and on the electrical distribution panel. Using this information, determine the required feeder wire size from Table 27. These sizes are based on an ambient temperature of 86 degrees Fahrenheit and do not take voltage drop into consideration. Acceptable conductor types are: RHH, RHW, RHW-2, THHN, THHW, THW, THW2, THWN, THWN-2, XHHW, XHHW-2, SE, USE, and USE-2. TABLE 27.

Installation of the electric power to the home can cause exposure to live electrical circuits. Exposure to live electrical circuits or improper grounding of the conductor in the panel board may result in severe shock or possible electro- cution. A qualified installer must make the connections for the electric power. I Manufacturer's Installation Manual - June 2015 71 FEEDER CONNECTIONS Feeder connections are made from above or from below the home as follows From above — mast weatherhead feeder The routing, connection, and support of the service drop must meet local codes. Homes equipped this way contain all pecessary conduits to the electrical distribution panel. However, the feeder conductors (not provided with the home) are installed on site. If the masthead is located above the roof overhang, allow a minimum clearance of eight feet above all roof points that the conductors pass over. There are two exceptions to this rule: (1) The vertical clearance may be reduced to three feet if the roof has a minimum slope of 4 in 12; and (2) The vertical clearance may be reduced to 18 inches if no more than four feet of service -drop conductors pass above the roof overhang, and if they terminate at a through -the -roof raceway or approved support. A minimum clear- ance must also be provided'from the final grade to the service -drop conductors. This measurement may vary from 10 feet to 18 feet; depending on the types of traffic antick pated below the service drop (refer to the NEC). Unless impractical, locate service heads above the point of attachment lof the service -drop conductors and make them rain -tight. If individual conductors do hot extend downward, form drip loops. From below — underside junction box feeder A section of conduit is factory installed through the floor cavity. Connect to that conduit with approved fittings and conduit (not provided with the home) to the point where the service entrance cable enters the crawl space. Install properly -sized service entrance conductors from the main power supply to the panel board. Depending on the location of the main panel board inside the home, or the point at which the service entrance conductors enter the crawl space, a separate service disconnect may be required. Re- fer to Table 27 for the conductor and junction box requirements. The installer must provide the supply connection including the feeder conductors, junction box, and con- duit connectors. Protect conductors emerging from the ground from a minimum of 18 inches below grade to eight feet abode grade, or to the point of entrance to the home. The distance measured from the topi surface of a buried cable, conduit, or raceway to the finished grade must meet the minimum burial requirements outlined in the NEC. Use a moisture -proof bushing at the end of the conduit from which the buried cable emerges. GROUNDING The home must be properly grounded to protect the occupants. The only safe and ap- proved method of grounding the ho T e is through an electrically -isolated grounding bar in the manufactured home distribution panel board. This grounds all non -current - carrying metal parts to the electrical) system in the home at a single point. Each neutral conductor must be coal nected to the system grounding conductor on the supply side of the main disconnect in accordance with Articles 250.24, 250.26, and 250.28 of the National Electrical Code, NFPA No. 70-2005. Where the meter base has a disconnect (typically when the meter is more than 6 feet from the service electric panel, although this may vary by LAHJ) the ground and neutral should be bonded at that disconnect and then grounded to the driven earth ground. Four wires will leave the service electric panel to the disconnect. Three wires will enter the disconnect from the meter base (refer to Figure 80). Where there is no disconnect on We meter base or between the meter base and ser- vice electric panel (typically when t.ke meter is within 6 feet from the service electric panel, although this may vary by LAHJ), the main circuit breaker in the service electric panel becomes the first disconnect. In this case, the neutral and ground are bonded in the service electric panel and connected to the driven earth ground from the service electric panel. Three wires lead between the meter base and the service electric panel (refer to Figure 81) 1 i // Power supply. A large enough power supply must be available at the site. An inadequate power supply may result in improper op- eration of and possible damage to motors and ap- pliances. It may also in- crease electricity costs. i ' // Grounding the electrical system. Do not provide electrical power until the grounding electrode is in- stalled and connected. When the meter base is not on the house never use the neutral conductor of the feeder cable as a ground wire. 72 1 Manufacturer's Installation Manual - June 2015 Service Entry Main Panel (May Be Above Or Below Ground) Enclosure ! _2'CondultTo a Neutral Service Head Equipment Bus Bar Ground Bus Bar Meter By Utility Metetbase Company Ground From Meter Enclosure Disconnect Bonding Strap 2' Conduit Not Installed Disconnect Grounding Lug 2' Conduit (Fused) To Chassis Installed at JLFactory To Main To Grounding Rod Metallic Conduit Or Fittings To Panel Be Effectively Grounded To Equipment Ground Black - °HOT' To A Or B Red -'HOT' To A Or B White To Neutral Bus Bar Ground To Equipment Grou d - Main Panel Service Entry Enclosure (Above Or Below Ground) ©-2'ConduitTo Neutral Service Head Equipment Bus Bar Ground Bus Bar Meter By Uglily Company Ll Bonding Strap Not Installed 2' Conduit Y Condu@ Grounding Lug r-Installed at Factory To Chassis To Main To Grounding Rod -Penell Metallic Conduit Or Fittings To Be Effectively Grounded To Equipment 1} `Black To A Or B' Ground -'HOT° Red -'HOT' To A Or B l White To Neutral Bus Bar In all cases, a grounding electrode conductor and a ground wire must be installed ac- cording to the following specifications: 1.

If manufacturer provides a minimum 112 inch EMT or conduit raceway, the #6 minimum bare cop- per wire is provided by the retailer for installation. 2. The clamp connecting the grounding wire to the electrode shall be suitable for di- rect burial and located flush or below ground level. 3. Use a listed 5/8 inch -diameter by eight foot long iron electrode or nonferrous rod of at least 1/2 inch diameter by eight feet long for grounding (larger sizes may be re- quired by the LAHJ due to soil impedance). 4. Drive the electrode to a depth of not less than eightlfeet so that at least eight feet of the electrode is in contact with the soil. 5. When rock is encountered, the electrode may be driven at an angle not to exceed 45 degrees from vertical or buried in a trench that is at least 2-1/2 feet deep. I FIELD INSTALLED METER BASE When a meter base is installed in the field, Figure 82 and the following requirements must be adhered to: • Install the meter base according to the manufacturer's instructions. • Use straps to support any conduit. Do not use the meter base equipment for support. • Use exterior equipment and enclosures listed as weatherproof and entrance conductors listed for wet locations. Figure 80. Electrical feeder connection when meter has a disconnect installed (typi- cally more than 6 feet from service electric panel). Figure 81. Meter base wiring when there is no separate disconnect installed (typically within 6 feet of service elec- tric panel). Manufacturer's Installation Manual - June 2015 73 I • The grounding bar may be installed separate from the neutral bar for purpos- es of testing the electricals Istem. • The grounding bar may be isolated during the electrical check and re- attached, after the tests are completed. • Check with the local electrical utility to verify meter base requirements and lo- cations and distances for the main panel and meter box. • The field installed meter base enclosure must be installed in accordance with its listing. Fasten securely to exterior wall studs and provide for a weather - tight seal. • Check the local code for any requirements regarding the location of the meter base. I Meter Exterior Wall Enclosure Air Space Between Meter Enclosure And Exterior Wall STEP 2. CONNECT W 'TER SERVICE CONNECTION To connect the home's water system to the water source, identify the water inlet locat- ed 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 dalve. 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. SelecIt 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. Figure 82. Meter base clearances. Maximum water pressure. The water system for the home was designed for a maximum inlet pressure of 80 psi. 74 I Manufacturer's Installation Manual - June 2015 Water Pipe Optional Hose Bib (Not Supplied) Connect To T a" Here For Water ---------- System Test 1, Service Connection (Not Supplied) Locate Water Riser Underneath or - Mandatory Shut-0ff Adjacent to Home Valve (Not Supplied) IOU I. 5. 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 1pressure relief valve to the out- side or to a sump. 1 6. Install water heater drip pan drain. Assure that the drain for the water heat- er drip pan does not terminate under the home! Using the materials provided 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 termina- tion point rodent proof. i 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 nearlthe water supply inlet. Figure 83. 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. Water heater drip pan and drain i ' // Selecting heat tape. Use only pipe -heating cable (tape) listed for manufac- tured homes, and install it in accordance with the ca- ble (tape) manufacturer in- stallation instructions. Testing water lines. Only use pneumatic (air) testing when hydrostatic testing is not practical. Air under pressure is explosive. Ex- ercise extreme caution and notify all site personnel of CHAMPION' Manufacturer's Installation Manual - June 2015 75 "=6U I►N After testing the electrical system and connecting the water lines check the water sys- tem for leaks using one of the proced res described below. Before testing, close all water faucets, spigots, and toilet-tankl float valves. Hydrostatic (preferred): 1. Fill water heater. Confirm that the water heater tank is full of water. 2. Pressurize system. Connect a hydrostatic pump, valve, and gauge to the lo- cation shown in Figure 83. Pressurize the system with water at 100 psi, and then isolate it from the pressure source.

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 LAW 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 11/10 lb. 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. B. Rinse connections. Thoroughly rinse all tested connections with water to remove leak detection fluid. Figure 85.

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 o the desired temperatures. STEP 4. CONNECT OIL SERVICE Homes that are equipped with oil bu(ning 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 wish 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 thei furnace oil control level. • Tanks for gun type oil furnaces (these furnaces include a fuel pump) may be installed above or below round. OIL SYSTEM TESTING Before operating the system, fill the tank to capacity with the fuel to be burned and visual - Iv check all ioints in the system for ileakaae. Replace (do not repair) parts that leak. i , /, Testing oil tanks. All oil storage tank and piping in- stallations and tests must meet all applicable local regulations and should be made only by experienced, qualified personnel. 78 I Manufacturer's Installation Manual - June 2015 Prepare Appliances and Equipment This chapter provides instructions for installing and/or preparing appliances and other equipment.

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, folio 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' coolers, 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 rIoof. 5. Install air supply. For roof-moilnted 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 t i at 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.
