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 or 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 fo(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. i • 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 installed in -accordance with their listings by a nationally recognized testing agency based on a nationally recognized testing protocol; or • System designs are prepared by a registered engineer or a registered architect or tested and certified by a regis- tered engineer or registered architect in accordance with acceptable engineering practice and are manufactured and installed so as not to take the home out of compliance with the Manufactured Home Construction and Safety Standards. DISPLAY AND STORAGE OF THE HOME WEATHER PROTECTION If the installation is not started immediately upon delivery of the home, the retailer and/or installer has the responsibility to ensure the exterior weather protection covering of marriage walls and the roof of homes with hinged roofs has not been damaged during shipment. Inspect the home immediately upon the delivery and frequently during storage. Promptly repair tears in the home closure materials to prevent damage from the 'elements. Inspect and repair roof shingles and siding as needed. SUPPORTING A HOME FOR DISPLAY When a new or used manufactured home is to be displayed at a retail location, temporarily block and support the home. Set up single -section homes with single block piers spaced no further apart than 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. 2, o^ 12.-0- 12-4- 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. I;n 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 MANUFACTURED BEAUTIFULLY, Getting S This chapter covers a few rted that, taken now, will avoid problems later in the installation process. STEP 1. LOCATE THE DATA PLATE Locate the data plate insideithe home (Figure 2), typically inside a kitchen cabinet door or on a wall panel or door f ,ce near the electrical 'Panel, utility room, or bedroom closet. The information on the dada plate will be used to verify that the home was designed for the proper location. STEP 2. CONFIRM WIND ZONE From Table 1, identify the Iwind 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. (Examp�e: a home designed for Wind Zone II cannot be placed in Wind Zone III.) • A home may be located In a lower wind zone than that indicated on the data plate. (Example: a home designed for Wind Zone II can be placed in either Wind Zone II or .) • Homes located within 1,500 feet of the coastline in Wind Zones II and III must be designed to 7ithstand 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. V&*Irliorz 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.

STEP 5. CHECK LOCAL CODES AND SECURE PERMITS Local regulations may set conditions for the siting and installation of a manufactured home. Consult the LAHJ, state manufactured housing association, and the state SAA (See Resources, p. 1) for the specific local requirements, including: • Building codes that may affect the construction of site built structures and infrastructure. • Local requirements regulating the installation of manufactured homes. • Setback requirements for property lines, streets, yards, and courts. Fire separation distances. • Development covenants for the specific property. • The locations of flood hazard areas and any special foundation requirements for homes installed in those areas. • In some areas, building permits are required to install manufactured homes. Prior to making any alteration to the site and the home, contact the LAHJ to determine if plan approval and permits are required. 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.

DETERMINE GROUND ANCHOR HOLDING CAPACITY (p. 14) STEP 1. PLAN SITE ACCESS Planning the route to the site is typically the responsibility of the retailer or transportation company. Whoever is resI onsible 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 hangs , g wires and trees, low overpasses, and bridges not suitable for the load. Contact the utility company if wires need to be moved. Do not allow branches, bushes, or other foliage to scrape against the home as the home is moved to the site. Avoid ditches, lberms, 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 or more). If required, provide for home storage and staging areas on the site. Plan the delivery and staging of home sections and materials so that after all deliveries are complete, home sections and materials can be accessed for use and installed in the appropriate sequence. Orient home sections so they do not have to be rotated or excessively maneuvered during the installation process. Plan for temporary needs, such as dumpsters, portable toilets, crew parking, delivery vehicle drop-offs and concrete mixer deliveries. Before moving the manufactured home to the site, inform the LAHJ and make sure the site is prepared and utilities are available. STEP 2. DETERMINE HOME LOCATION AND LAYOUT The home location may ave already been determined by others. If not, plan the home location and layout in compliance with the regulations researched in Getting Started, STEP 5. CHECK LOCAL CODES AND SECURE PERMITS (p. 9). Contact utilities for locations of existing infrastructure, such as underground cables, pipes, and electrical lines. I When planning the site'mprovements, consider the following: • The home location should be level. • Avoid contact With large trees, steep slopes, poorly drained areas, and poten- tial flood zones. • Preserve trees and shrubs for shade, visual screens, and windbreaks. • Plan the drive] ay, parking areas, septic, well, other structures, and utility lines. • Consider future additions, such as screen rooms, porches, and awnings. • Site the home away from natural water paths. ' // Site Preparation. The home manufacturer has. no con- trol over the site planning and installation of the home unless the manufacturer is responsible for the home's installation. Final responsi- bility for site preparation, including soil stability and frost heave control, lies with the installer. An improperly prepared site may result in the denial of a foundation - related warranty claim. ' // Fire separation. Comply with any LAHJ fire separa- tion requirements or the re- quirements NFPA 501A, 2003 edition (Chapter 6). 10 Manufacturer's Installation Manual - June 2015 STEP 3. CLEAR AND GRADE THE SITE Trim overhanging foliage considering future growth, potential storms, swaying in wind and snow/ice-weighted branches. Remove organic material such as vegetation, wood, roots, twigs, dead branches, grass, and brush from directly under the home. Remove any debris that could become termite infested from the site and surrounding area. Re- move all other debris from the home location, including roots from beneath footing loca- tions. Properly dispose of all items. Crown the site (Figure 4) so that water will not accumulate or stand underneath the home. Also, slope away from the foundation for the first ten feet with a minimum slope of 1/2 inch per foot. Where property lines, walls, slopes, or other, physical conditions prohibit this slope, provide the site with drains, swales, or grading to drain water away from the structure. Any fill required to grade the site should be inorganic "controlled fill" applied in a maximum of four inch layers, compacted between each layer to at least 90% of its maximum relative density. Direct runoff away from the site using ditches and berms (Figure 5). If .the home will have skirting, start grading from two feet in from the edge of the home. k Al- y Hc use y A�' y y � yyyyy y y, Avows Indicate direction of water i flow. Grade the ground so that water under porches, decks, and recessed entries flows away from the home. If proper grading is not possible, use other methods such as a drain tile and automatic sump pump system to remove any water that may collect un- der the home. The home is suitable for the installation of gutters and downspouts. When gutters and downspouts are installed, direct runoff away from the home. STEP 4. DETERMINE SOIL CONDITIONS Examine the soil type under the proposed home location to make sure it is suitable for placement of a home. The design of the home's support system, including footing/pier spacing and size, will in part be determined by the bearing capacity of the soil, and ground anchors by the soil's withdrawal strength. The soil under every portion of the support system must meet the following criteria: The soil must be firm and undisturbed (not previously excavated) or fill com- pacted to at least 90% of its maximum relative density. Uncompacted fill will set- tle over time, causing the home to shift and become 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 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. Z&*�� 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. M.��.��,�q.o aeAUT1fV1Y_ Manufacturer's Installation Manual - June 2015 1 1 • The soil must not bye 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 wit, 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 fol�owing methods to determine the site's soil bearing capacity: • Test the soil. Hide a registered geologist, registered engineer, or registered architect to dete ine 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.Qov) and/or the LAW may haveltest results and/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing capacity as follows: 1. Select a location that will be under a footing. 2. Clear an area of a minimum of one square foot at least four inches deep or to the depth of the bottom of the planned footing. 3. Using the instructions provided with the pocket penetrometer, take at least five readings. 4. Discard the high and low readings and average the remaining readings. Round this Iresult down to the nearest soil -bearing value shown in the right column of Table 4. 5. Confrim thot 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 mailable, 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 classifvinq the soil found on the site. V&*IrZZA 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 TABLE 4.

Use an allowable pressure of 1,500 psf, unless site - specific information requires the use of lower 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. Keep a record of the frost depth; it will be used later to design the home's support system. 3' d Figure 6.

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. 15) STEP 2. ' DESIGN FRAME SUPPORTS (Homes Without Perimeter Blocking) (p. 19) STEP 3.

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.

Those under homes with 10" or 12" deep I -beams may be no more than 10 feet apart. Generally, greater distances between supports will require larger footings.

DESIGN FRAME AND PERIMETER SUPPORTS (Homes With Perimeter Blocking) DETERMINE LOCATIONS Depending on design and loc tion, 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 suppork's 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 locations for homes requiring perimeter supports.

Place the bot- tom of the footings below the frost line (insulated foundations and monolithic slabs are other frost protection options not covered in this manual). • Make sure the top surface of the footing is level, flat, and smooth. • In accordance with the American Concrete Institute publication ACI-308, main- tain curing measures before construction or installation onto the concrete foot- ing begins, until a minimum of 70% of the specified 28-day compressive strength has been achieved. The ACI recommended time to attain this level of strength is seven days for ASTM C150 Type 1 mixtures and 10 days for Type II mixtures. Full design live and dead loads may not be applied until the 28-day duration has elapsed for achieving full strength. Excavation. If excavation is required, mark the footing locations on the ground with stakes before beginning to dig. Manufacturer's Installation Manual - June 2015 25 Construct Foundation (FOR HOMES WITH LOAD-, EARING PERIMETER WALL) This chapter provides guidelines and 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.

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 around the perimeter of the home. Interior piers must be supported by a slab or footings. If footings are used under interior piers, they may be designed as in Install Footings, p. 15. • Slabs must extend to the edges of the home. • Footings andlslabs must be protected from the effects of frost heave by ex- tending the footings to or below the frost line or by using a frost protected shallow foundation design. STEP 2. EXCAVATE Excavate for the foundation, properly disposing of the earth that is not needed for backfill or site -grading purposes. STEP 3. CONSTRUCT THE FOOTINGS OR SLAB Construct the foundation according to the approved design, including the perimeter foundation wall, drainage system, footing(s), and/or slab. STEP 4. CONSTRUCT THE PERIMETER WALL Unless the approved design requires otherwise, construct the perimeter wall with mor- tared and reinforced concrete blocks or reinforced poured -in -place concrete. Install re- inforcement according to the approved design or LAHJ. Install ventilation and access openings accordinglto the approved design, or if not specified, according to the re- quirements in Complete Exterior Work, STEP 3 INSTALL SKIRTING (p. 90).

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. Fc basements, check for a high water table. The water table may vary seasonally or bass 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. I • 26 Manufacturer's Installation Manual - June 2015 1 MAN-c..... ._1 i UIIY When constructing pockets for an H-beam system, measure the beam depth and locate the pockets carefully. It is critical that when the home's frame rests on top of the H-beam, the perimeter of the floor rests squarely on the 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 maintain a minimum of two inches of bearing area for the beams in the pockets (yielding a minimum pocket depth of three inches). Bolt a pressure treated wood sill plate (minimum 2 x 6) to the top of the foundation wall. 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. STEP 5. INSTALL INTERIOR SUPPORTS Install piers, columns and H-beams to support the interior of the home according to the approved design. STEP 6. DAMP PROOF FOUNDATION WALL Damp proof the foundation wall no less than up to the height of the planned backfill. STEP 7. BACKFILL AND GRADE Backfill against the foundation wall to the height of the damp proofing. Take care to not damage the drainage system. Grade the fill as per Prepare the Site (p. 10). Levei ine wau. iviaKe sure the foundation is level and straight with no more than a 1/4 inch vertical variation over the entire foundation and no more than 1/8 inch vertical variation over any two -foot length. Check for Plates. When us- ing an H-beam system, check and compensate for reinforcement plates that add thickness to the chas- sis beam at axle locations. Figure 15. Omitted Figure 16.

PREPARE FOR SET Before beginning the home set, complete the following: • Confirm that the site is properly cleared and graded (see Prepare thI 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 wl II foundations: • Check that they length and width of the home match with the foundation walls. • Check that the two main diagonal measurements of the foundation are equal. • Check that the foundation walls 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 Hbeam 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 frst). Then place materials needed to construct support piers near their final locations under the home as determined in Install Footings, (p. 15). STEP 3. LIFE 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 ' /, 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 CHAMPION 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%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). Figure 17. Stack 4"x 6" by 5' long timbers as shown to form safety timbers. Place safety timbers under home behind axle area and under hitch. - - - - - - - - 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. • M.NU-1-11e.[AUTIFULLV' Manufacturer's Installation Manual - June 2015 29 ROLLER SYSTEMS When using a roller system, the following sequence: 1.

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

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

I • 32 Manufacturer's Installation Manual - June 2015 MANUTACTU[CD ICAUTIIUIIY• A water level is a standard device for leveling the home. The level consists of the following components: • One container (five gallon bucket or one gallon jug). • 150 feet of 1/2 inch diameter plastic tubing. • Fittings for container to tubing. • Valve for terminal end of tubing. • Liquid for system: colored water in warm climates, windshield washing fluid in cold climates. Cantina, am to use a water level cm.e !a. Position level. Position the level such that it can reach all piers. b. Place container. Place the container so that the fluid in the con- tainer is at the same level as the desired level of the top of the supports under the home, allowing for any bracing below the lev- el of the I -beams. c. Uncoil tubing. Uncoil the tubing and fill with fluid, taking care not; to introduce bubbles into the hose. Never allow anything to crimp or crush the tubing so as to impede the free flow of fluid. d. Bleed air. Hold the valve below the level of the water container; open the valve to bleed out any air and close the valve. e. Establish height. Locate the tubing adjacent to a pier that is set to the desired final height. Position the valve above the pier and open the valve. Move the water container up or down to where the water level is at the desired final height of the pier. Maintain the water container in that position and close the valve. f. Level piers. Move the tubing to the next pier. Hold the valve above the pier and open it. Set the pier height to the level of the water in the tubing and close the valve. Repeat this step until all 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. i , // 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). • M�Nur�eruuo ..�urnuur• Manufacturer's Installation Manual - June 2015 33 Complete (Multi -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.

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

Remove protruding nails and staples or anything else that will keep the home sections from fitting together snugly. If present, cut the temporary ceiling and floor plates at the edges of marriage line openings tak- ing care not to damage ceiling or floor coverings or displace temporary mar- riage line support posts (these supports and the plates will be removed after the home sections have been structurally connected). 2. Complete crossovers. Before moving the two sections together, complete any crossover connections that require access from the open marriage line, including the attic duct connection (if present) and marriage wall interior elec- trical connections (see Connect Crossovers, p.49). 3. Position section. Position the section as closely as possible (ideally within six inches) and line up with the previously set section. If using a mechanical positioning system or crane, follow the system manufacturer's instructions or the crane operator's directions. 4. Construct piers. With the outside walls of the home aligned, construct the piers for the home section according to the instructions in Set the Home (p. 28) before continuing to the steps below. 5. Level section. Lower the section onto the outside piers first, inside piers last. Before releasing the mechanical positioning system, check interior doorways and other openings for misalignments that may cause problems during trim - out. The floors should be flush, level, and tight and the roof section should have little, if any, gap at the top of the marriage line. Use at least two come -a - longs to pull the sections snugly together and use the water level or other lev- eling device to set all piers and shims. 6. Shim gaps. Shim any gaps up to one inch between structural elements with dimensional lumber. If any gaps exceed one inch, re -position the home to eliminate such gaps. STEP 6. CONNECT FLOORS Make floor structural connections according to the method described below. Install toed fasteners through bottom board Install fasteners at approximately a 45 degree angle (+/- 5 degrees) from horizontal as shown in (Figure 29) using the fastener type, size, and spacing indicated on Table 13. TABLE 13. FLOOR CONNECTION FASTENING SPECIFICATIONS * Increase fastener lengths by 3 inches for double rim joists. Figure 28. Marriage Line Gasket Mechanical posi- tioning system. For a pier - set home, a mechanical positioning system (such as a roller system) will make the process easier and saf- er and be less likely to damage the home. A Sealing gaps. Prior to com- pletion of the exterior close- up, gaps that do not exceed one inch are permitted be- tween structural elements provided that the gaps are closed before completion of close-up, the home sec- tions are in contact with each other, and the mar- riage gasket provides a proper seal.

CONNECT DUCTS There are three main types of duct crossover connections. Based on the location of the duct, follow the installation steps on the page indicated below: • Under the floor (p. 49). • In the roof cavity (p. 51). • In floor, through -the -rim joist (p. 51) To prevent air leakage, seal all ductwork connections, including duct collars using one or more of the following materials: • Galvanized metal straps in combination with galvanized sheet metal screws. • For rigid air ducts and connectors, tape and mastics listed to UL 181A. • For flexible air ducts and connectors, tape and mastics listed to UL 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 crossover duct must be listed for exte- rior use. There are four common configurations of under floor crossover ducts depending on the number of home sections and the furnace/air handler location. See Table 20 to locate the appropriate figure. TABLE 20. UNDER FLOOR DUCT CONFIGURATIONS locationFurnace Furnace over trunk duct See Figure 50 See Figure 52 Furnace offset from trunk duct See Figure 51 y See Figure 53 VA ' ZZ 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.

Manufacturer's Installation Manual - June 2015 59 Install Stabilizing Systems This chapter covers the design and installation of the stabilizing system which secures the home against lateral and up- ward forces caused by wind! The system covered here uses earth (or ground) anchors and steel straps connected to the home's longitudinal steel beams and/or exterior walls. Stabilizer plates shall be used to prevent the anchor head from moving laterally in the ground. An anchor, strap, and stabilizer plate together are referred to as a tie -down. Anchors can also be mounted in concrete footings when there is enough concrete mass (weight) to resist the lateral and upward forces. This type oflsystem is not covered in this manual. STEPI.

The manufac- tured home must be se- cured against the wind by the use of an anchor assembly or an alterna- tive foundation system. Where site or other conditions prohibit the use of the manufactur- er's instructions, a reg- istered engineer or reg- istered architect must design the stabilizing system. Flood and seismic forces. The stabilizing system re- quirements in this chapter do not consider flood or seismic loads and are not intended for use in flood or seismic hazard areas.

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

June 1, 2015 64 Manufacturer's Installation Manual - June 2015 SIDEWALL VERTICAL ANCHORS Homes designed for Wind Zones II and III also require vertical tie -downs along the sidewalls. The vertical tie -down anchor straps (or brackets for connecting to the home) are factory installed and indicate the locations. Vertical and frame sidewall tie -downs shall connect to one double -headed anchor. Any factory -installed sidewall tie -down straps must be connected to a ground anchor regardless of the wind zone in which the home is placed. END WALL FRAME ANCHORS End wall frame tie -downs are especially important for homes that are wider and have higher roof pitches because those features increase the surface' area exposed to wind loads at the ends of the home. Use Table 25 to determine the number of end wall frame anchors required at the each end of each home section. TABLE 25. END WALL FRAME ANCHORS REQUIRED PER,HOME SECTION ON EACH END OF THE HOME MAXIMUM ROOF PITCH 4.35 / 12 END WALL VERTICAL ANCHORS End wall vertical anchors are not required. TAG UNIT FRAME ANCHORS (WIND ZONE I ONLY) Use sidewall anchor quantity on end walls and use end wall anchor quantity on side walls. TAG UNIT VERTICAL ANCHORS Tag unit vertical anchors are not required. PORCH POST ANCHORS Wind Zone I anchors not required. Wind Zone II and III anchors located at vertical straps. OFFSET UNIT ANCHORS Anchor same as single section home (Figure 8). STEP 2. DETERMINE TIE -DOWN CONFIGURATION There are two primary tie -down configurations: the near beam and the far beam methods. If the anchor spacing selected in the appropriate anchor table (Table 22, Table 23 or 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. PHILLIP J.

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. 2. Install anchor. To assure that the anchor attachment point will end up at the stabilizer plate, start the anchor insertion approximately 12 inches back from the desired location if using a 48 inch long anchor, or approximately 16 inches if using a 60 inch long anchor. Install the anchor at about 15 degrees off verti- cal, with the head tilted away from the home. Install the anchor to a depth of approximately one half its length. 3. Drive stabilizer plate. Drive the stabilizer plate into the ground to its full depth at the point determined in Step 1. 4. Complete anchor installation. Screw the anchor the rest of the way into the ground. The finished anchor must be installed to its full depth. VERTICAL ANCHORS To install vertical anchors, screw the anchor into the ground directly under the strap at- tachment point on the home until the bottom of the anchor head is flush with the ground or no more than one inch above grade.

For anchors with stabilizer plates, pretension the anchor by pulling it up to the stabilizer plate using the strap and take-up bolt to move the anchor head. Continue pulling the strap until the plate moves a small amount (about 1/2 inch). This is called packing the plate and it will yield the strongest resistance (the bottom of the anchor head should be maximum 1/4 inch above the top of the stabilizer plate). END WALL FRAME ANCHORS Attach straps to the bracket welded by the manufacturer to the frame (Figure 79). If no brackets have been installed, use approved beam clamps designed specifically for this purpose, available from anchor suppliers. Connect straps to anchors following same procedure as for sidewall frame anchors. When more than one anchor per frame is re- quired, use swivel brackets and space anchors a minimum of 48 inches o.c.

Responsibility for making utility connections varies by location. Consult the LAHJ and the utility before connecting the home to any utilities. STEP 1. 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 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. MANUFACTURED BEAUTIFULLY' 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 cdntain all necessary 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 poll Its 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; aid (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 fro 1 10 feet to 18 feet; depending on the types of traffic antici- pated below the service drop (refer to the NEC). Unless impractical, locate service heads above the point of attachment of the service -drop conductors and make them rain -tight. If individual conductors do not 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 �ower 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 craw 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 above grade, or to the point of entrance to the home. The distance measured f�om the top surface of a buried cable, conduit, or raceway to the finished grade must nl eet 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 home 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 connected 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 willlleave 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 the meter base or between the meter base and ser- vice electric panel (typ'cally when the 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 7ires lead between the meter base and the service electric panel (refer to Figure 81) 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 Manufacturer's Installation Manual - June 2015 Ground Bus Bar Grounding Lug To Chassis Metallic Conduit Or Fittings To Be Effectively Grounded To Equipment Ground — Ground Bus Bar Grounding Lug To Chassis To Grounding Rod Metallic Conduit Or Fittings To Be Effectively Grounded To Equipment Ground — Service Entry Main Panel (May Be Above Or Below Ground) Enclosure f-2' Conduft To Neutral Service Head Bus Bar Meter UutilityCompann y Meter Enclosure Bonding Strap Not Installed Disconnect 2' Conduit (Fused)—� Installed at Factory To Main Black -'HOT° To A Or B Red - °HOT' To A Or B White To Neutral Bus Bar Ground To Equipment Ground Ground From Disconnect ,2' Conduit To Grounding Rod Main Panel Service Entry Enclosure (Above Or Below Ground) 2'ConduitTo Neutral Service Head Bus Bar Meter By UtllltyCompany t2- Meter EnclosureBonding Strap Not Installed Conduit 2' Conduit � 'Installed at Factory To Main —Panel Black - °HOT° To A Or S Red - •HOT' To A Or B 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 1/2 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 eight feet 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. 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.

Inspect the drain opening on the water heater to ensure that it is clear of any obstruction. If the home is to be installed on a basement or enclosed crawlspace, install drain pipe connecting the dis- charge from the water heater temperature and pressure relief valve to the out- side or to a sump. 6. Install water heater drip pan drain. Assure that the drain for the water 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. 7. Insulate. In areas subject to freezing temperatures, protect with insulation or heat tape pipes, valves and pressure reducers that are exposed to the outdoors; and pipes in water heater compartments with non -insulated doors. Connect heat tape to the electrical outlet under the home near the water supply inlet. 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.

Inspect vents. Assure that all exhaust vents on gas -fired' equipment are se- curely connected and that roof jacks and stacks have not come loose during transit and they are properly installed. 2. Review appliance instructions. Review each appliance manufacturer's in- structions before the home is connected to the gas supply. Most gas appli- ances are typically configured to operate on natural gas. If the gas supply will be LPG, consult the appliance manufacturer's instructions to determine what changes need to be made. For homes located above 3,000 feet, appliances may require a different orifice. 3. Remove cap. Remove the protective cap from home inlet pipe and install a full flow shut-off valve at the supply inlet (Figure 85). 4. Install regulator. The gas piping system is designed for a pressure that is at least seven inches of water column (4 oz. per sq in or 0.25 psi) but not more than 14 inches of water column (8 oz. per sq in or 0.5 psi). If gas from any supply source exceeds, or could exceed this pressure, install a regulator if re- quired by the LAHJ. 5. Connect supply. Using matching threaded fittings, connect the gas supply to the inlet side of the shut-off valve. 6. Close valves. Close all valves at appliances prior to opening the main supply valve. Full Flow Shutoff Valve Required (Supplied By Others) Source of Gas TESTING Union (Supplied By Others) Test the gas piping system in the following two ways: 1) piping only and 2) entire sys- tem.

Conduct the tests when and where air temperatures will re- main constant. Piping only test (all appliances isolated) 1. Isolate appliances. Isolate all appliances from the system by closing all ap- pliance shut-off valves. 2. Attach gauge. Attach to the home's gas inlet a mercury manometer or slope gauge calibrated in increments of not more than 1/10 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. 8. Rinse connections. Thoroughly rinse all tested connections with water to remove leak detection fluid. Figure 85.

CONNECT OIL SERVICE Homes that are equipped with oil burning furnaces must have oil supply piping installed and tested on site by a qualified professional in accordance with NFPA 31, Standard for the Installation of Oil Burning Equipment, 2001 or the requirements of the LAHJ, which- ever is more stringent. The home manufacturer does not supply oil piping or tanks. OIL CONNECTION Consult the furnace manufacturer's instructions for proper pipe -sizing and installation procedures. Where piping is run through the bottom of the home, ensure all holes in the bottom board are sealed tight with foam, mastic, and/or tape specially made for that purpose and made ro ent proof. When equipping the h me with an oil storage tank, comply with the following: • Install the pnine 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 re�dily accessible approved manual shut-off valve at the outlet, in- stalled to close against the supply. • Equip the.tal k with an approved oil filter or strainer located downstream from the tank shy t-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 lof the compartment to permit diffusion of vapors. If the tank is fixed to the l home, provide for filling and draining from the outside. • Insulate interior tanks from the structural members of the home. Provide tanks so installe6 with an outside fill and vent pipe and an approved liquid level gauge. • Install tanks that feed vaporizing type oil furnaces so that oil flows by gravity. To achieve efficient gravity flow, make sure that the bottom of the tank is at least 18 inches above the furnace oil control level. • Tanks forlgun type oil furnaces (these furnaces include a fuel pump) may be installed above or below ground.
