Copyright © 2008 Manufactured Housing Research Alliance ISSN 1529-3424 Iv Manufacturer's Installation Manual - June 2015 Introduction This installation manual contains instructions that must be followed for the proper installation of the home. 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 Ithe 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 ttie 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. IAII 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,I 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 ME time of installation. The installer may be responsi manual. ation or for the materials supplied by the set-up crew at the for any deviations from the installation instructions of this • 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 anlchorage 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. • l The installer must possess a valid installation licenlse as a manufactured home installer. • If the installer identifies failures of the home to comply with the Federal Manufactured Home Construction and Safety Standards (the HUD Code), the installer mu'I t 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 oflIinjury. 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.

Examine the soil type under the pl', posed home location to make sure it is suitable for placement of a home. The design of•ihe, 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 str6,ngth. j 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. Uncompactedfill 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'i planned support; system/ foundation. A soil's bearing capacity can be greatly reduced when it is isaturated with water. Note that water tables may vary with seasonal or climactic condi- tions: Consult a geologist or the LAHJ if you are unsure of the water table level. I I i ' /, Site drainage. Moisture un- der the home can result in structural damage to the floor system and other parts of the home. Failure to provide adequate slope/drainage can result in moisture -related problems such as mold, mildew, and erosion. Figure 4. (Left) Crown or keep soil flat under the home be- tween the outer beams to pre- vent water ponding Figure 5. (Right) Direct runoff away from the home V&*#Z-ZJ 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. • i �,,,��,r_ Manufacturer's Installatioh Manual - June 2015 11 • The soil must not be a highly expansive type. Expansive soils can expand when they become saturated with water, causing the home to shift and become un- leveled. If soils are expansive, contact a registered engineer, or registered ar- chitect to assist with the Idesign of the foundation system. STEP 5.

SOIL -BEARING CAPACITY LINE apable of withstanding the loads imposed by the (stem and furnishings, as well as any loads imposed conditions. in pounds per square foot (psf) before designing a icity (psf), the more weight the soil can hold without firing capacity increases, footings can be reduced in Use one or more of the following methods to determine the site's soil bearing capacity: • Test the soil. Hire a registered geologist, registered engineer, or registered architect to determine the soil classification and maximum allowable soil bear- ing capacity by testing the soil in accordance with generally accepted engi- neering practice. l • Obtain soil records. l7he local office of the U.S. Department of Agriculture's Natural Resources Conservation Service (www.soils.usda.4ov) and/or the LAHJ may have test results and/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing capacity as follows: 1. Select a location ithat 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 readinqs. 4. Discard the highland low readings and average the remaining readings. Round this result down to the nearest soil -bearing value shown in the right column of Table 4. 5. Confrim that thel rounded result matches the soil description on Table 4.,,,,- Determine soil -bearing value by visual examination. If one of the 00iions above is not available, the values on Table 4 can be used to establish soil - bearing capacity bylvisual 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&AZZ 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 inaccufate reading. 12 I Manufacturer's Installation Manual - June 2015 7 ABLE 4. 5EAL-BEARING CAPACITY BY SOIL TYPE i Soil TypeAllowable Rock or hardpan (class 1) 4,000 Sandy gravel and gravel; very dense and/or cemented sands; I 2,000 I bbl I d d •It 1 d 1 1 2 course grave co es, pre oa a si s, c ays an cora (c ass ), Sand, silty sand; clayey sand; silty gravel; medium dense course 1',500 sands; sandy gravel; very stiff silt, sand clays (class 3) Clay, sandy clay, silty clay, clayey silt (classes 4A and 413) I 1,000 Uncompacted fill, peat, organic clays (class 5) Professional testing required Note to table: No allowances made for overburden pressure, emyedment depth, water table height, or settlement problems. • Use default capacity.

In this Le, 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.

DESIGN FRAME AND PERIMETER SUPPORTS (Homes With berimeter 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 lonly 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.

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. i 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. I � • 26 Manufacturer's Installation Manual - June 2015 ...I-IUEED BEAUTIIU[IY- 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). i 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. INSTALL INTERIOR SUPPORTS Install piers, columns and H-beams to support the interior oflthe home according to the approved design. STEP 6. DAMP PROOF FOUNDATION WALL Damp proof the foundation wall no less than up to the heights, 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). Level the wall. MaKe sure the foundation is level and straight with no more than a 1/4 inch vertical variation over the entire foundation and no more than 1/8 inch vertical variation over any two -foot length. Check for Plates. When us- ing an H-beam system, check and compensate for reinforcement plates that add thickness to the chas- sis beam at axle locations. Figure 15. Omitted Figure 16.Omitted Limits of exca- vation. When a crane will be used, excavate no more than two feet outside the foundation perimeter.

PREPARE FOR SET Before beginning the home set, complete the following: • .Confirm that the site is properly cleared and graded (see Prepare the Site P. 10.) • Ensure that the footings are in place and properly located. • Install any utilities that will be difficult to install (e.g. those below grade beneath the home) after the hol a 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. Immediat y report any damage or shortages to the manufacturer. • The ground moisture retarder may be installed now or after the home is com- plete. See Complete Exterior Work, STEP 2. INSTALL GROUND MOISTURE RETARDER (p. 89) for requirement and then return here. For perimeter bearing wall foundations: • Check that the lengthland 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 H-beam system, remove the frame's shackle hanger if it will inter- fere with proper placement of the beam. STEP 2. POSITION HOME SECTION Position the home section in its final location (if possible, move the heaviest section of the home into place first). Then place materials needed to construct support piers near their final locations under thel home as determined in Install Footings, (p. 15). STEP 3. LIFT HOME There are three primary methods available to place the home on the foundation: jacking, rolling and craning. Jacks, often with roller systems, are typically used for pier and anchor foundations; roller systems are commonly used for crawlspace foundations with load - bearing perimeter walls; andl cranes are most commonly used for basement foundations. V&*IrZZA 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 MANUfACTUPED lEAUTIIULLY• 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 1-beams). • To distribute the concentrated loads from jacks to I-beam, place a minimum 3/8-inch thick steel plate, a C-channel, a 1'/2-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). 000` ,EllZ N!1 i 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). i 4. Locate frame jacks. Place a minimum of one jack just'iforward of the first spring hanger and another just behind the last spring hanger of the 1-be6m 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 avid 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 ihigher than the final desired pier height. Figure 17.

Do not poisition lifting straps under marriage wall openings. • Use a properly sized spreader bar to maintain a vertical lift, to avoid placing compression forces on. the eaves and to reduce any tendency to slip. • Connect a rope to at least one point on the home so it can be controlled while aloft. • Make provisions to retrieve the straps/cables after the home is set. If using a cradle system, notch the sill plate where the straps will fall. For a sling sys- tem, notch and reinforce the home's rim joist to keep the strap from slipping and allow the strap tolbe removed after the home is set. • Always set the home section farthest from the crane first so that subsequent section(s) need not be lifted over previously set sections.

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. V Cha®h i We Lh. C...h.r Pler T� How to use a water level a. Position level. Position the level such that it can reach all piers. b. Place container. Place the container so that the fluid in the con- tainer is at the same level as the desired level of the top of the supports under the home, allowing for any bracing below the 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 piers are at the same level. 6. Complete the opposite side. Jack the other side of the section up and install piers following the instructions above. At the completion of this step, the sec- tion should be level from front to rear and from side to side. 7. Install perimeter and marriage line piers. Install perimeter piers and for multi -section homes, marriage line piers. Position marriage line piers to pro- vide equal bearing for both mating sections. 8. Remove running gear. Remove and store, recycle or properly dispose of the hitch, axles, and wheels. These items are the property of the homeowner 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). • 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.

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;points for up to 60 feet, and five lift points for up to 72 feet. 2. Remove fasteners. Remove any temporary fasteners connecting the hinged por- tion of the roof to the vertical king posts. 3. Lift roof. Raise the roof to its intended height. A temporary slight overextension may be required during lifting. However, take care not to overextend the roof and damage the hinge. Raise the roof evenly in small increments, keeping it level throughout the entire process to prevent racking. Do not allow roofing paper and shingles to get caught in the hinge crease. V&10zzA 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.

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 pates 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. I STEP 6. CONNECT FLOORS Make floor structural connections according to the method described below.

CONNECT DUCTS I 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 galva i ized 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 d it ct 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 I See Figure 52 Furnace offset from trunk duct j; See Figure 51 l; See Figure 53 i ' /, 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. i MA.0.111.... ..AVINILY' Manufacturer's Installation Manual - June 2015 49 A Section Heat Duct - Tap -Out Collar — Field -Installed Flex Duct A Section Heat Duct--� Tap -Out Collar Field -Installed Flex Dud Furnace / Air Ha® B Section Floor 4imo.exu Support Straps Furnace /Air Ha® B Section Floor Flex Duct Support Straps "V"-Box Under Furnace Furnace / Air A Section HanBdler B Section C Section I Floor INM I Heat Tap-Out I Collar Field -Installed Flex Dud "V'-Box Under Furnace Flex Dud Support Straps Furnace/Air A Section Handler B Section C Section Feld -Installed Flex Duct "V"-Box Under Furnace I In-line'V"-Box Flex Duct Support Straps For under floor flexible crossove i ducts follow the steps below: 1.

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

MANUFACTURED BEAUTIFUL - Manufacturer's Installation Manual - June 2015 i 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 of system is not covered in this manual. STEP 1.

DETERMINE ANCHOR LOCATIONS Create a sketch of the home plan showing the exterior walls, marriage line(s) (if any) and frame I -beams (this will be similar milar to the base sketch created in Install Footings, page 15). See Table 21 for a list of anchor locations, types, and where they are required. Pages where the requirements are provided are noted in the last column. As each anchor location is determined, mark it on the sketch, noting important dimen- sions such as spacing between anchors. When complete, this will be the home's tie - down plan (Figure 70 and Figure 71). TABLE 21. ANCHOR LOCATION TYPES Frame I Yes Yes 61 Vertical �4 No Yes 65' Frame I Yes Yes 65 . wail Vertical " . �..

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. In those areas retain a regis- tered engineer or registered architect to design the sta- bilizing system.

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 thecharac- 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.. I Figure 70.

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 con I ected to a ground anchor regardless of the wind zone in which the home is placed. I 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 surtace 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.

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 thel home's main frame beams. For Wind Zones II and III connect one anchor strap !rom the anchor head (using a double -headed anchor) to the home's far beam and one to the sidewall of the home.

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 LAHJ may have stabilizer plate requirements. Install anchors with stabilizer plates as follows: 1. Locate anchor. Select a location for the anchor four inches of the exterior wall Figure 74. Avoid with skirting.

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 itsl full depth at the point determined in Step 1. 1 i 4. Complete anchor installation. Screw the anchor the rest of the way into the ground.

CONNECT OIL SERVICE Homes that are equipped with oillburning 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 Eg6ipment, 2001 or the requirements of the LAHJ, which- ever is more stringent. The home manufacturer does not supply oil piping or tanks. Is] X0161►II'll I*t081►J Consult the furnace manufacturer's instructions for proper pipe -sizing and installation procedures. Where piping is run through the bottom of the home, ensure all holes in the bottom board are sealed tight with foam, mastic, and/or tape specially made for that purpose and made rodent proof.) When equipping the home with an oil storage tank, comply with the following: • Install the pipe with a gradual slope toward the fill end or drain plug (if so equipped) to facilitate pumping or draining of water and sludge. • Provide a readily acce§sible 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. l • Install tanks that feed vaporizing type oil furnaces so that oil flows by gravity. To achieve efficient gravity flow, make sure that the bottom of the tank is at least 18 inches above the furnace oil control level. • Tanks for gun type oil furnaces (these furnaces include a fuel pump) may be installed above or bolow ground.

Repair large openings. Repair large openings with a durable patch made -of bottom board fabric or other compatible material and fastened with vinyl bot- tom board tape held in place by fasteners installed with a divergent stapler. Seal the edges around patches with foam or mastic. For large openings, in- stall a rigid backer board behind the bottom board to provide a fastening sub- strate for the patch. 3. Repair small openings. Repair small gaps and tears with a combination of vinyl bottom board tape, patches, mastic, or foam sealant. Alternate materials may be used to repair and seal the bottom board provided they are appropriate for the type of repair and installed per the manufacturer's installation instructions. STEP 2. INSTALL GROUND MOISTURE RETARDER If the space under the home is to be enclosed with skirting or other materials, a ground moisture retarder of a minimum six mil thick polyethylene s eeting or equivalent must be installed covering the ground under the home. Moisture retarders are not required in and regions (less than 15 inches of rainfall annually) with dry soil conditions., If on - grade (surface) footings are used, install the ground moisture retarder prior to placing the footings, or install it around the footings after all other work under the home is com- plete. Install the ground moisture retarder as follows: 1. Apply sheeting. Unroll the ground moisture overlapping joints in the sheeting a minimum of 12 inches and covering the entire area under the home except for areas under recessed entries, decks, and porches. 2. Weigh down. To keep the retarder in place, weigh its down with stones , concrete blocks, or other heavy, durable materials. 3. Repair tears. Repair any large voids or tears in the retarder by patching with like material, maintaining a minimum 12 inch overlaps, secured with tape or•ad- hesive. Repair small voids and tears with tape, adhesive or per manufacturer's installation instructions. Sealing bottom boards. A con- tinuous and sealed bottom board is critical for home per- formance, energy efficiency, protection against moisture problems, prevention of pipe freezing, and protection against insects and rodents. Bottom board sealing meth- ods. Tapes shall never be used alone to repair a bottom board. Divergent staples or mastic must be used in tandem with tape to prevent future tear off. Fastening vinyl siding. Do not install fasteners directly into vi- nyl siding. Allow for siding ther- mal expansion by pre -drilling minimum 1/2 inch diameter fas- tener holes or fastening skirting to a ledger under the home (see Best Practice tip). Avoiding radon. For enclosed perimeter wall crawlspace foundations in areas where radon is com- monly found in the soil, continue the moisture re- tarder up the perimeter wall at least 12 inches, sealing the edges and between the seams with mastic. MANUfACTV1ED I[AVTIIUIIY` Manufacturer's Installation Manual - June 2015 89 STEP 3. INSTALL SKIF.TING Skirting is any structural or non-strtctural perimeter crawlspace enclosure. Complete site -built structures (see STEP 5. COMPLETE SITE -BUILT STRUCTURES, p.92) that abut the home (such as porches, attached garages, and steps) prior to installing skirting TABLE 28. SKIRTING MATERIALS SPECIFICATIONS Skirting must be of weather -resistant materials or provided with protection against weather deterioration at least equivalent to that provided by a coat - Skirting ing of zinc on steel of not less than 0.30 oz per sq ft of surface coated. Skirting made from wood or wood products and used within six inches of the ground needs to be made of materials naturally resistant to decay and termite infestation or pressure -treated. Ventilation openings must be covered for their full height and width with a perforated (114 inch maximum opening in any dimension) corrosion and Vents weather -resistant covering that is designed to prevent the entryof rodents. In areas subject to freezing, the coverings for the ventilation openings must have an operable damper, permitting them to be in the open or closedposi- tion depending on the weather. To design and install skirting, comply with the skirting manufacturer's instructions (if provided) and the following: 1. Configure skirting. Run the skirting along the perimeter of the home's heated, conditioned space (Figure 96). Do not enclose with skirting areas under recessed entries, porches, or decks (whjether constructed as part of the home or added on site) unless skirting is of the frilly vented type and installed so as to allow water to freely flow out from under the home. 2. Fasten skirting. Recess the skirting under the siding or trim and attach it to the home in a manner that preve9ts water from being trapped between the siding or trim and the skirting. For wood, aluminum, or fiberglass skirting, install a skirt rail (lumber strip) under the floor inset at least 1-1/2 inches from the edge of the siding for attachment of the skirting. How for frost heave when installing skirting .in areas subject to frost. 3. Provide ventilation. Unless the skirting has integral ventilation openings that meet the following ventilation requirements, install equally sized ventilation openings on at least two opposite sides of the foundation. Size ventilation area to equal at least one square foot for each 150 square feet of under -floor area (or for each 1,500 square feet if a ground moisture retarder is installed according to STEP 2. INSTALL GROUND MOISTURE RETARDER, p. 89). Place vents as high above the ground as practical. 4. Install access. Provide an access opening not less than 18 inches wide and 24 inches high and located so thi t any utility connections located under the home are accessible. 5. Extend vents, drains, and Inlets. Run appliance exhaust vents, combustion air in- lets, and air conditioner condensation drains through the skirting to the outside and terminate each as instructed in the sections of this manual corresponding to each appliance.
