Using the Manual This manual is organized into a series of steps that will take you through the entire installation process using only those pages required for the specific home being installed. First, review the entire manual, including the Introduction chapter. As you read it, identify sections of the manual that you will need; identify other documents or information you will need; construct lists of tools and materials required for your particular installation; and make sure you have) everything you need before starting work. After reviewing the entire manual, refer to the sequence of installation steps inl the table below. Identify the pathway for your installation and follow the arrows downward. Select either Single Section Home or a Multi -Section Home and choose the col- umn corresponding to the home's foundation type, either Pier and Ground Anchor or Load -Bearing Perimeter Wall (see Def- initions, p. 4). Then complete the work in each of the sections starting with Getting Started. If using an alternative (proprietary) foundation system, the installation process will change from that described in this manual. Consult the system manufacturer directions for instructions. See page 6 for alternative foundation system criteria. APPROVED BY ON REVISED 5pj/8II/2017 IIVC.

It complies with e HUD Model Manufactured Home Installation Standards. Please read all instructions and any other documents (includ- addendum pages and supplements) that may apply to the specific home prior to commencing site work or installation. its installation manual covers permits and site work through final inspection of the installation. It covers both single and ulti-section homes installed over pier and anchor, load bearing crawl space walls and basement foundations. It contains structions, including specifications and procedures, for the set and hookup of manufactured homes to be used as single- mily dwellings. ie importance of correct installation cannot be over -emphasized. Correct installation is absolutely essential to home- vner satisfaction and the structural integrity of the home. All instructions must be followed to provide the customer with a de, quality home. manual can cover all circumstances that may exist for certain home designs or building sites. For questions, further arification, or if you encounter conditions at the site or in the design of the home or its foundation not covered by this anual, please contact the manufacturer (see Resources, p. 3), a registered engineer, or registered architect. ipplemental addendum pages may be included with this manual. Supplements include requirements not covered in this anual or that supercede the manual instructions. the home installation is complete, leave this manual with the home. MPOR `ANT NOTICES • The home manufacturer is not responsible for installation or for the materials supplied by the set-up crew at the time of installation. The installer may be responsible for any deviations from the installation instructions of this manual., • To keep the home in compliance with its warranty, the home installation must follow the procedures described in this manual or other procedures approved by the manufacturer. Deviation from the instructions in this manual may void the home's warranty. Any alterations or changes to the home shall be approved by a registered engi- neer or registered architect and may still be subject to warranty violations. • When an installer does not provide support and anchorage in accordance with the approved manufacturer's in- stallation instructions, or encounters site conditions (such as areas that are subject to flood damage or high seismic risk) or other conditions that prevent the use of the instructions provided in this manual, the installer must obtain special site -specific instructions from the manufacturer or use a design approved by a registered engineer or registered architect. • The installer must possess a valid installation license as a manufactured home installer. • If the installer identifies failures of the home to comply with the Federal Manufactured Home Construction and Safety Standards (the HUD Code), the installer must notify the manufacturer and retailer. SAFETY There are potential hazards associated with the installation of a manufactured home. Home installers are licensed, and as experienced professionals, should recognize these hazards, be qualified to work with them, and be capable of providing safe work practices and equipment that minimize the risks of injury. Only qualified persons should install a manufactured home. As qualified professionals in the field of manufactured home installation, installers are the experts and must be aware of the hazards and conditions faced. Warnings are published throughout this manual as reminders. These reminders may not cover all hazards, all potential hazards, or all possible consequences of improper or unsafe installation practices. Construction crews should be trained in the skills required and be supervised by experienced personnel. Installers should regularly inspect work performed by crews and subcontractors.

DETERMINE SOIL CONDITIONS Examine the soil type under the proposed home location' to make sure i 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 if ground anchors are used, 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 excavat�d) or fill com- pacted to at least 90% of its maximum relative density. Uncompacted fill will settle over time, causing the home to shift and become unlevel. • 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. Site drainage. Moisture: n- 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, I;and erosion. Figure 4. Crown the soil un- der the home to prevent wa- ter ponding Figure 5.

GA 31503 SUB: Footing Dear Wayne: 167 Below Grade Apr 20, 2009 In accordance with your request I am summarizing standard construction practice regarding the placement of footings below grade in foundation construction. A common building code stateFDent is that the footings must be located below frost depthl and also at least 12" below grade. This common specific tion is intended to insure footings do not heave due to ground freezing and that footings are placed below the surface top soil which may be unstable or compressible. Footings should always be located below frost depth unless it is known the soil it the site is of a type that prevents ground heave ('.e., excellent drainage with- out capillary action) or the soil is sufficiently heated to prevent freezing. In Georgia the frost depth is typically not very deep m and y extends several inches into the ground (consult thellocal building official for the depth required at thq foundation site). The 12" dimension below grade is intended to insure the footing is placed on stable soil without excessive settlements (i.e., insures fo tings are located below organic matter). This dimension may be reduced if the local site conditions provide a stable soil at shallower depths or the footings are pl ced on properly compacted soil or stable rock. Since it is impossible to knot the site conditions when the Set -Up Manuals are approv d the standard code require- ments are often quoted in thelSet--Up Manuals. However, these requirements may be modified based on the'know- ledge of the site conditions 4s indicated above. Note, local and/or state installation regulations will supersede the specifications �n the Set -Up Manual. The local building official shoull be consulted regarding the requirements in his area and the acceptability of any changes regarding the installation requirements specified in the Set -Up Manuall.

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. ROLLER SYSTEMS When using a roller system, comply with the equipment manufacturer's directions and the following sequence: 1. Establish staging area. Establish a staging area directly adjacent to one or both sides of the foundation. 2. Setup rollers. Set up the roller system according to the equipment manufac- turer's directions. 3. Fasten bump blocks. Temporarily fasten wooden bump blocks on the sill plates at the ends of the foundation to stop the home from rolling at the de- sired location. 4. Roll home. Roll the home into place over the foundation. 5. Remove bump blocks. Remove the blocks before installing the next section of a multi -section home. CRANES When using a crane, follow these guidelines: • Position the home section(s) and crane (taking the boom reach into consider- ation) such that they do not have to be repositioned during the set. • Use enough properly sized straps to maintain balance of the home and to prevent damage to the structure. • Place straps under walls or posts, including temporary posts used to support the opening. Do not position 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 to be 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. STEP 4. CONSTRUCT PIERS For the side of the home section that is up on jacks, place piers on footings or pads fol- lowing the home manufacturer's blocking plan (or tags). If no plan was provided, use the support plan developed in Install Footings (p. 18). Start at one end of the home section and work toward the other noting the required'pier material specifications and procedure described below. Construct piers so as to provide a stable foundation for the home using materials listed in the specifications box below and based on the location of the pier and its height as APPROVED BY ONO 3/9/2017 INC.

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. 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 16). 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 dimensional lumber (two inches maximum thickness) or 2" or 4" thick concrete block. For split caps, install shims and dimensional lum- ber/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 piers. Carefully lower the side of the section down onto the leveled piers, adjusting the final height with shims.

CONNECT ROOF If the marriage line along the roof is not snug, position jacks every 20 feet or less along the outside I-beam and uniformly lift the section until the roof area is tight. Check to make sure the ceiling joint is flush before installing the connections. If not, use a jack and tee to raise whichever ceiling is low, starting at the front and working to the rear of the home. Fasten the roof along the marriage line using one of the methods below for either double or triple -section homes. DOUBLE -SECTION HOMES Make roof structural connections in double -section homes according to the one of the methods described below. Method 1: Install toed fasteners through roof sheathing Install the fasteners through the roof deck into the ridge beams at an approximately 45 degree angle (+/- 5 degrees) from horizontal (Figure 20) according to the fastener spacing and specifications in Error! Reference source not found.. Stagger fasteners on each side of marriage line and offset them by half the spacing distance (Figure 18). Spacing indicated is on -center, both sides of ridge.

ATTACK TAG UNITS After the main unit has been set on its foundation, install all tag units according to the following procedure: 2. 3. Position and block the tag. Position the tag unit as close to the main unit as possible at its intended location. Use a hitch jack to obtain• approximate level- ing and install pier supports according to Set the Home, STEP 2. POSITION HOME SECTION (p. 29). Determine whether the tag and main unit floors are designed to line up flush or are offset by a step and adjust the tag pier heights accordingly. Level the unit. Using a water level (p.34), verify that the piers are level. The elevation of all points along the lower flange of the I-beam should be no more than 318 inches from the desired height and should not deviate more than 3/4 inches overall. Connect floors. If the floor of the tag unit is level with main unit floor, connect the floors together as described in -STEP 5. CONNECT FLOORS (p. 46). Connect walls. Secure the tag unit walls to the main unit sidewall using #8 x 4" screws at 12 inches o.c. (see Figure 22). The sheathing shown in the detail may not be included by the manufacturer. If included, the sheathing over the last stud bay was tacked in place at the factory for easy removal at the site. Once the wall connections are complete, re -install the sheathing and complete the siding installation. 4. Connect roofs. Connect the tag unit roof to the main unit roof p. See Figure 23 for flush roof connections and Figure 24 for roof connections with an offset greater than two inches. Roof connections with an offset less than two inches do not require screws. V&Irzzj Piers under tag units. Some tag units have spe- cial piering needs due to the roof and/or floor con- struction. These will be de- tailed in supplemental pier- ing plans supplied with the home. Note that tag unit end walls are typically load bearing rather than side walls. Figure 22.

Installing metal panels or flashings on a windy da can be dangerous and should be avoided if possible. Cutting Aluminum Panels ` To make a cut parallel to the ribs, score the panel deep ly with a sharp utility knife and bend back -and -forth along the score, breaking the metal off cleanly. For cuts across the ribs, us. straight -cut snips, electric or pneumatic shears, a portable proffl• shear, or an electric nibbler. Some installers prefer using a circula saw with a metal cutting blade:(a fine-tooth hardwood blade, or. standard combination blade reversed in the sawworks also). Liigh oil or soap on the blade will make cutting easier. - Cutting and Drilling Steel Panels Steel panels may be cut with metal snips, electric or pneu matic shears, a portable profile shear, or an electric nibbler. Soml installers prefer using a circular saw to cut metal panels. Do Nc use self-consuming abrasive blades because of the following: 1 Abrasive blades burn the paint and galvanizing at the cut edge leaving edges that are jagged and unsightly and rust more quickl 2. Abrasive blades produce hot metal filings that embed in th, paint and cause rust marks on the face of the panel. If saw cuttin; cannot be avoided, select a carbide -tipped blade specially da signed for cutting light -gage ferrous metal panels. These blade are now available at many home centers and lumber yards. 1. A saw cut panels must be turned face down and cut in a locatioi down -wind and well away from the building and other panel to avoid embedment of metal filings on other panels 2. All sav cut panels must be thoroughly wiped to ensure the removal c all metal filings, Pre -drilling will panels gives uniform alignmen of screw rows. Be sure to remove any filings once panels are in stalled to avoid rust marks from the filings.

FEDERAL MANUFACTURED HOME CONSTRUCTION AND SAFETY STANDARDS 1-83 83 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 platesi may also be used to prevent the anchor head from moving laterally in the ground. An anchor, strap, and stabilizer plate (if used) 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.

Alternatively, ABS stabilizer plates may, be used when listed and certi- fied-for.such"use.: ' EP 4. INSTALL ANCHORS )re beginning anchor installation, check for obstructions under the home such as s and frame members that may interfere with the tie down strapping. Check with y companies to determine the location of underground utilities, such as electrical phone lines, and water, sewer, and gas pipes that may be buried in potential an - locations. Also check for homeowner -installed wires and pipes, such as those iecting exterior lighting or sheds to the home. These must also be avoided. FRAME ANCHORS Frame anchors can be installed in two ways, in -line and against a stabilizer plate. The two methods are discussed below: In -Line Configuration The in -line configuration (Figure 54) for homes can be used in Wind Zone I only. Typi- cally, in -line anchors are used under high homes where the anchors can be installed from under the home after the home is set. In -line anchors can also be installed before the home is set, however, precisely aligning the anchor with the home both vertically and horizontally is difficult. Using swivel connectors for the strap to beam connection can provide some horizontal flexibility. To install in -line frame anchors, drive the anchor into the ground at an angle and loca- tion such that a straight line can be drawn from the tip of the anchor through the anchor head and to the connection point on the I-beam (Figure 55). Beam Sidewall Frarne Tie -Down Strap Ground Anthorwilh Stabilizer Plate Stabilizer Plate Configuration Stabilizer plate configurations (Figure 55) are suitable for homes in all wind zones. An- chors may be installed after the home is set. A stabilizer device, typically an ABS or metal plate, is used to prevent the top of the anchor from slicing through the soil when the load is applied. Stabilizer plates are available in a variety of widths. Choose the widest plate that can be driven into the soil to maximize resistance to movement. The LAHJ may have stabilizer plate requirements. 1-93 Grading area around anchors. Anchor heads should not rest in sunken spots. Grade the ground so that water does not collect around anchor heads, but runs away from the anchor and out from under the home. Do not bury anchor heads. Figure 54. In -line anchor configuration Figure 55. Stabilizer plate configuration APPROVED BY REVISED NiH5//8I/2017 iI VC. FEDERAL MANUFACTURED HOME CONSTRUCTION AND SAFETY STANDARDS 93 Install anchors with stabilizer plates as follows: 1. Locate anchor. Select a location for the anchor under the home but within six inches of the exterior wall (Figure 56). Avoid locations that will interfere with skirting. �1ti!i�i�i�i44�i�i� 2. Install anchor. To assure that the anchor attachment point wil� end up at the stabilizer plate, start the anchor insertion approximately 12 inchles back from from the desired location if using a 48 inch long anchor, or app oxlmately 16 inches if using a 60 inch long anchor. Install the anchor at abo t 15 degrees off vertical, 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 th6 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 and r the strap at- tachment point on the home until the bottom of the anchor head is flush frith the ground or no more than one inch above grade. STEP 5. INSTALL STRAPS Follow the instructions below to connect straps from the home to sidewall frame, end wall frame and vertical anchors. Always protect straps at sharp corners including around I -beams with radius clips or other methods (Figure 67). Radius clips may be fabricated from 26ga (mij) by 1 1/4- inch wide galvanized steel strap formed to fit around corners. i Longftudal Brack I Protect Top and Bottom of Boom if / I -Beam N SUap is Wrappetl Around Beam SPLICING STRAPS Splicing may be required when a pre-cut strap is of insufficient length. Spli es in tie - down straps are not permitted in a'Y' configuration. Overlap straps by 12 i ches, ap- plying one splice clip from above and the other from below; use a crimpingr� ool to tight- ly seal the splice clips (Figure 58). Do not run any portion of the splice through an an- chor head bolt. I Figure 56. Determining an- chor and stabilizer plate loca- tion Soil depression.

Connect the other end of the strap to the split bolt in the anchor. Leave enough strap length to be able to make at least three, but no more than five complete turns around the bolt before it becomes tight (approximately 2 1/2 inches per turn or 7 1/2 to 13 inches total). Fewer than three turns and the strap may not hold onto the bolt when force is applied. Conversely, more than five turns may not fit within the U-channel of the an- chor head.

For anchors with stabilizer plates, pretension the anchor by pulling it up to the stabilizer plate using the strap and take-upI 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 ill yield the strongest resistance (the bottom of the anchor head should be aximum 1/4 inch above the top of the stabilizer plate).

FEDERAL MANUFACTURED HOME CONSTRUMON AND SAFETY STANDARDS ROUNDING he 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 the supply side of the main disconnect in accordance with Articles 250.24, 250.26, and 250.28 of the National Electrical Code, NFPA No. 70-2005. Where the meter base has a disconnect (typically when the meter is more than 6 feet from the service electric panel, although this may vary by LAHJ) the ground and neutral should be bonded at that disconnect and then grounded to the driven earth ground. Four wires will leave the service electric panel to the disconnect. Three wires will enter the disconnect from the meter base (refer to Figure 63). Where there is no disconnect on the meter base or between the meter base and ser- vice electric panel (typically 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 wires lead between the meter base and the service electric panel (refer to Figure 64). 0 Z&* Grounding the electrical system.

FEDERAL MANUFACTURED HOME coNSTRUcm AND SAFETY STANDARDS 7. Insulate. In areas subject to freezing temperatures, protect with insulation or heat tape pipes, valves and pressure reducers that are exposed to the out- doors; and pipes in water heater compartments with non -insulated doors. Connect heat tape to the electrical outlet under the home near the water sup- ply inlet. After testing the electrical system and connecting the water lines check the water sys- tem for leaks using one of the procedures described below. Before testing, close all water faucets, spigots, and toilet -tank float valves. Hydrostatic (preferred): 1. Bypass water heater. Bypass the hot water heater by disconnecting the hot outlet and cold inlet water lines from the water heater and joining them to- gether. This will protect the hot water tank from damage and protect those in- volved in the test from possible injury. 2. Fill water heater. Confirm that the water heater tank is full of water. 3. Pressurize system. Connect a hydrostatic pump, valve, and gauge to the lo- cation shown in Figure 66. Pressurize the system with water at 100 psi, and then isolate it from the pressure source. Bleed all air from the highest and far- thest points in the system. 4. Hold pressure. Monitor the pressure for at least 15 minutes. 5. Fix leaks. If the pressure drops below 100 psi, locate and correct any leaks by cutting out and discarding bad pipe sections or joints and installing new pipe or joints with couplings. 6. Repeat. Repeat the test until all leaks have been eliminated. Pneumatic: 1. Bypass water heater.

REPARE FIREPLACES tall chimneys, chimney flashing and roofing, fireplace combustion air inlets, and h arths according to the manufacturer's instructions and the procedures described be- MNEYS place and wood stoves may require on -site installation of additional sections of ap- red chimney pipe, a spark arrestor, and a rain cap assembly. Follow the manufac- r's instructions and the procedures described below: 1. Remove coverings. Remove protective materials covering the roof flashing and any foreign material from the installed part of the chimney. 2. Install chimney pipe. Assemble and seal the chimney per the fireplace or wood stove manufacturer's installation instructions and if there is a conflict be- tween the instructions and the figure, follow the instructions. To assure suffi- cient draft for proper operation, extend the chimney at least three feet above the highest point where it penetrates the roof and at least two feet higher than any surface within 10 feet of the chimney (Figure 74). Use additional sec- tion(s) of chimney pipe (not provided) if required by local code or if the site has obstructions within 10 feet of the chimney. ,—Root Top Assmty Above f APPROVED BY REVISED 5/8/2017 NiHINC. FEDERAL MANUFACTURED HOME CONSTRUCTION AND SAFETY STANDARDS Figure 73. Chimney and combustion air intake duct installation Selecting the appropriate flue. Wood fireplaces use larger diameter flues than gas fireplaces. Make sure flue matches the appliance type. Gas fireplaces cannot bum wood because the flue is too small and smoke will back up into the home. If wood fireplaces are con- verted to gas the flue will be too large resulting in ex- cessive heat loss through the chimney. Figure 74. Chimney clear- ance 1-119 119 leTss Thann11V I 12'h1in. 3.
