0 SWU > W > 10 "0 ® OCT 1 6 2008 � INTRODUCTION C' PLEASE READ THIS MANUAL BEFORE BEGINNING SET-UP Federal Manufactured Home Construction rn And Safety Standards Thank you for purchasing a Nobility Home. Your home was designed, engineered, inspected, tested and approved to be in conformance with the Federal Manufactured Home Construction and Safety Standards in effect at the time of manufacture. This manual is intended to furnish information for site preparation, foundation and piers, tie down and electrical, plumbing and utility connections. THE IMPORTANCE OF CORRECT SET-UP CANNOT BE OVEREMPHASIZED. Correct set-up is absolutely essential to homeowner satisfaction. If you are not certain of the proper procedure, or you encounter unusual conditions, please refer to the procedures contained in this manual, or contact your dealer or factory service representatives. Set-up should be done only by qualified and preferably professionally trained installers. Installer means the person or entity who is retained to engage in or who engages in, the business of directing, supervising, controlling or correcting the initial installation of a manufactured home, as governed by part 3285 of this chapter. The contractor or dealer performing the set-up must be licensed and bonded in the state of Florida. The homeowner, with the dealer and set-up crew supervisor, should inspect the work to see if the home is properly set-up and any problems found should be corrected as soon as possible. Manufactured homes are designed to meet specific wind, thermal and roof load zones. The zone maps are included on the following page. The data plate is located in the master bedroom closet and specifies which zones the home was designed for. A home placed in the wrong zone does not meet the requirements of the Federal Manufactured Home Construction and Safety Standards. Installation suitability. (a) Site appropriateness. Before installing a manufactured home at any site, the installer must assure that the site is suitable for installing the home by verifying that (1) The site is accessible; (2) The site is appropriate for the foundation or support and stabilization system that is to be used to install the home in accordance with the federal installation standards or alternative requirements in part 3285 of this chapter; (3) The data plate required by §3280.5 of this chapter is affixed to the home, that the home is designed for the roof load, wind load, and thermal zones that are applicable to the intended site; and (4) The installation site is protected from surface run-off and can be graded in accordance with part 3285. (b) Installer notification of unsuitable site. If the installer determines that the home cannot be installed properly at the site, the installer must: (1) Notify the purchaser or other person with whom the installer contracted for the installation work, identifying the reasons why the site is unsuitable; (2) Notify the retailer that contracted with the purchaser for the sale of the home, identifying the reasons why the site is unsuitable; (3) Notify HUD, identifying the reasons why the site is unsuitable; (4) Decline to install the home until the site and the home are both verified by the installer as suitable for the site under this section; and (5) Ensure that all unique characteristics of the site have been fully addressed. (c) Installer notifications of failures to comply with the construction and safety standards. If the installer notices and recognizes failures to comply with the construction and safety standards in part 3280 of this chapter prior to beginning any installation work, during the course of the installation work, or after the installation work is complete, the installer must notify the manufacturer and retailer of each failure to comply. (d) Retailer notification. The retailer must provide a copy of the notification receiver in paragraphs (b) and (c) of this section to any subsequent installer.

Where property lines, walls, slopes, or other physical conditions prohibit this slope, the site must be provided with drains or swales or otherwise graded to drain water away from the structure, as shown in figure 1. The home must be protected from surface run-off surrounding area. Grade site that there will be no depressions in which surface water may accumulate beneath the home. Manufacturers must specify in their installation instructions whether the home is suitable for the installation of gutters and downspouts. If suitable, the installation instructions must indicate that when gutters and downspouts are installed, the runoff must be directed away from the home. This home is not designed for gutters and downspouts. 10' MIN. �MINIMUM SLOPE 1/2 IN. PER FT. FIGURE 1 To help prevent settling or sagging, the foundation must be constructed on firm, undisturbed soil or fill compacted to at least 90 percent of its maximum relative density. All organic material such as grass, roots, twigs, and wood scraps must be removed in areas where footings are to be placed. After removal of organic material, the home site must be graded or otherwise prepared to ensure adequate drainage, in accordance with §3285.203. Foundations for homes designed for and located in areas with roof live loads greater than 40 psf must be designed by the manufacturer for the special snow load conditions, in accordance with acceptable engineering practice. Where site or other conditions prohibit the use of the manufacturer's instructions, a registered professional engineer or registered architect must design the foundation for the special snow load conditions. Ramadas may be used in areas with roof live loads greater than 40 psf. Ramadas are to be self-supporting, except that any connection to the home must be for weatherproofing only. The soil classification and bearing capacity of the soil must be determined before the foundation is constructed and anchored. The soil classification and bearing capacity must be determined by one or more of the following methods, unless the soil bearing capacity is established as permitted in paragraph (f) of this section: (a) Soil test. Soil tests that are in accordance with generally accepted engineering practice; or (b) Soil records. Soil records of the applicable Local Authority Having Jurisdiction (LAHJ); or (c) Soil classification and bearing capacities. If the soil class or bearing capacity cannot be determined by test or soil records, but its type can be identified, the soil classification, allowable pressures, and torque values shown in Table to §3285.202 may be used. (d) A pocket penetrometer; or (e) In lieu of determining the soil bearing capacity by use of the methods shown in the table, an allowable pressure of 1,500 psf may be used, unless the site - specific information requires the use of lower values based on soil classification and type. (f) If the soil appears to be composed of peat, organic clays, or uncompacted fill, or appears to have unusual conditions, a registered professional geologist, registered professional engineer, or registered architect must determine the soil classification and maximum allowable soil bearing capacity.

Notes: 1 The values provided in this table have not been adjusted for overburden pressure, embedment depth, water table height, or settlement prob- lems. 2 For soils classified as CH or MH, without either torque probe values or blow corset test results, selected anchors must be rated for a 4B soil. sThe torque test probe is a device for measuring the torque value of soils to assist in evaluating the holding capacity of the soil in which the ground anchor is placed. The shaft must be of suitable length for the full depth of the ground anchor. 4The torque value is a measure of the load resistance provided by the soil when subject to the turning or twisting force of the probe. If the space under the home is to be enclosed with skirting or other materials, a vapor retarder must be installed to cover the ground under the home, unless the home is installed in an and region with dry soil conditions. A minimum of six mil polyethylene sheeting or its equivalent must be used. The entire area under the home must be covered with vapor retarder, except for areas under open porches, decks, and recessed entries. Joints in the vapor retarder must be overlapped at least 12 inches. The vapor retarder may be placed directly beneath footings, or otherwise installed around or over footings placed at grade, and around anchors or other obstructions. Any voids or tears in the vapor retarder must be repaired. en 1 VAPOR RETARDER PATCH HOLE PATCH TAPE HOLE IN VAPOR RETARDER MUST HAVE PATCH OF EQUIV.

The design is base o adf ( r IVe� load of 40 pounds per square foot (P.S.F.) and a south zone roof live load of 20 P.S.F. in conjunction with the home structural dead load. (a) Foundations for manufactured home installations must be designed and constructed in accordance with this subpart and must be based on site conditions, home design features, and the loads the home was designed to withstand, as shown on the home's data plate. (b) Foundation systems that are not pier and footing type configurations may be used when verified by engineering data and designed in accordance with § 3285.302(d), consistent with the design loads of the MHCSS. Pier and footing specifications that are different than those provided in this subpart, such as block size, metal piers, section width, loads, and spacing, may be used when verified by engineering data that comply with §§ 3285.301(c) and (d) and are capable of resisting all design loads of the MHCSS. (c) All foundation details, plans, and test data must be designed and certified by a registered professional engineer or registered architect, and must not take the home out of compliance with the MHCSS. (See 3285.2) (d) Alternative foundation systems or designs are permitted in accordance with either of the following: 1. Systems or designs must be manufactured and installed in accordance with their listings by a nationally recognized testing agency, based on a nationally recognized testing protocol; or 2. System designs must be prepared by a professional engineer or a registered architect or tested and certified by a professional engineer or a registered architect in accordance with acceptable engineering practice and must be manufactured and installed so as not to take the home out of compliance with the Manufactured Home Construction and Safety Standards (part 3280 of this chapter) PIER TAGS All pier locations required at the mating line, perimeter, shear wall, and any special pier support locations, as required by these instructions, will be identified from the factory by a pier tag, paint, or other means and must be visible after the home is installed. The pier designs, support loads, and footing construction shall be as indicated in the appropriate, tables and instructions. Refer to Figure 4 for an approved foundation and pier arrangement designed by Nobility Homes, acceptable for all Nobility models, using readily available concrete footing slabs and pier caps with cellular concrete blocks. Before an installer provides support or anchorage that are different than those methods specified in the manufacturer's installation instructions, or when the installer encounters site or other conditions (such as areas that are subject to flood damage or high seismic risk) that prevent the use of the instructions, the installer must: First attempt to obtain DAPIA- approved designs and instructions prepared by the manufacturer; or if designs and instructions are not available from the manufacturer, obtain an alternate design prepared and certified by a registered professional engineer or registered architect for the support and anchorage of the manufactured home that is consistent with manufactured home design, conforms to the 3 requirements of the MHCSS, and has been approved by the manufacturer and the DAPIA. In making the certification of the installation required under part 3286 of this chapter, upon effect, an installer must certify that it completed the installation in compliance with either the manufacturer's instructions or with an alternate installation design and instructions that have been prepared by the manufacturer or by a registered professional engineer or registered architect.

Materials approved for footings must provide equal load -bearing capacity and resistance to decay, as required by this section. Footings must be placed on undisturbed soil or fill compacted to 90 percent of maximum relative density. A footing must support every pier. Footings are to be either: a. Concrete. i. Four inch nominal precast concrete pads meeting or exceeding ASTM C90-02a, Standard Specification for Load bearing Concrete Masonry Units (incorporated by reference, see §3285.4), without reinforcement, with at least a 28-day compressive strength of 1,200 pounds per square inch (psi); or I Six inch minimum poured -in -place concrete pads, slabs, or ribbons with at least a 28-day compressive strength of 3,000 pounds per square inch (psi). Site -specific soil conditions or design load requirements may also require the use of reinforcing steel in cast -in -place concrete footings. b. Pressure -treated wood. i. Pressure -treated wood footings must consist of a minimum of two layers of nominal 2-inch thick pressure -treated wood, a single layer of nominal 3/-inch thick, pressure -treated plywood with a maximum size of 16 inches by 16 inches, or at least two layers of 3/-inch thick, pressure -treated plywood for sizes greater than 16 inches by 16 inches. Plywood used for this purpose is to be rated exposure 1 or exterior sheathing, in accordance with PS 1-95, Construction and Industrial Plywood (incorporated by reference, see § 3285.4) ii. Pressure treated lumber is to be treated with a water -borne adhesive, in accordance with AWPA Standard U1-04 (incorporated by reference, see § 3285.4) for Use Category 4B ground contact applications. iii. Cut ends of pressure treated lumber must be field -treated, in accordance with AWPA Standard M4-02 (incorporated by reference, see § 3285.4) c. ABS footing pads. i. Abs footing pads are permitted, provided they are installed in accordance with the pad manufacturer installation instructions and certified for use in the soil classification at the site. ii. ABS footing pads must be listed or labeled for the required load capacity. d. Other materials. Footings may be of other materials than those identified in this section, provided they are listed for such use and meet all other applicable requirements of this subpart. 5 2. Placement in freezing climates. Footings placed in freezing climates must be designed using methods and practices that prevent the effects of frost heave by one of the following methods: a. Conventional footings. Conventional footings must be placed below the frost line depth for the site unless an insulated foundation or monolithic slab is used (refer to §§ 3285.312(b)(2) and 3285.312(b)(3)). When the frost line depth is not available from the LAW, a registered professional engineer, a registered architect, or registered geologist must be consulted to determine the required frost line depth for the manufactured home site. This is not subject to the provisions in § 3285.2(c) that also require review by the manufacturer and approval by its DAPIA for any variations to the manufacturer's installation instructions for support and anchoring. b. Monolithic slab systems. A monolithic slab is permitted above the frost line when all relevant site -specific conditions, including soil characteristics, site preparation, ventilation, and insulative properties of the under floor enclosure, are considered and anchorage requirements are accommodated as set out in § 3285.401. The monolithic slab system must be designed by a registered professional engineer or registered architect: i. In accordance with acceptable engineering practice to prevent the effects of frost heave; or ii. In accordance with SEUASCE 32-01 (incorporated by reference, see § 3285.4). c. Insulated foundations. An insulated foundation is permitted above the frost line, when all relevant site -specific conditions, including soil characteristics, site preparation, ventilation, and insulative properties of the under floor enclosure, are considered, and the foundation is designed by a registered professional engineer or registered architect: i. In accordance with acceptable engineering practice to prevent the effects of frost heave; or ii. In accordance with SEUASCE 32-01 (incorporated by reference, see § 3285.4). 3. Sizing of footings. The sizing and layout of footings depends on the load bearing capacity of the soil, footings, and the piers. See § § 3285.202 and 3285.303, and Table to 3285.312. 4. Place piers on both sides of sidewall exterior doors, patio doors, and sliding glass doors; under porch posts, factory -installed fireplaces, and fireplace stoves; under jamb studs at multiple window openings; and at any other sidewall openings 48 inches or greater in width. Piers are to be installed at each end of joint wall openings 48 inches and greater. See Figure 3, 4, and 5. For roof loads of 40 psf or greater, a professional engineer or registered architect must determine the maximum sidewall opening permitted without perimeter suV=rtigned for 40 psf roof loads. W o OCT 1 6CL zoo$ CL Federal Manufactured C11 Home Constrtwtion �4 And Safety standards 0 5. Additional end wall piers are to be installed under double wide joint edge joists at the point of end wall juncture. They should span both joint edge joists and be located adjacent to the end cross member/outrigger. The pier should be capable of supporting a 3100 pound load. See Figures 4 and 5. 6. Additional side wall piers may be necessary. Concentrated weight along outside walls (like a piano) may create a sagging condition. This can be corrected or prevented by installing piers under the edge joist. POSITIONING Determine the appropriate foundation system for the local site and wind exposure conditions as described in the Support Requirements section. Establish the location of each pier and tie down point for the length and width of the home and the locale in which the home is being installed. Install any components that might be difficult to place after the home is in position. An example of this would be ground anchors, poured footings, etc. Then move the home into the desired final position. Reminders before jacking... 1. Use only jacks in good condition with minimum rating of 10 tons. 2. Use jack reinforcing plates when jacking the frame main beam to avoid damage to the beam or home structure (see Figure 6 for typical). 3. Use a firm support or footing under the jack base to prevent tipping or settling of the jack under load. 4. Always follow the sequence of jacking outlined below to avoid overstressing structural members. 5. Use a minimum of two experienced installation men and closely coordinate jacking and blocking activities. 6. Keep clear from under the main frame beam to prevent injury should the home suddenly drop by accident.

If for any reason there are questions unanswered in this procedure, it is suggested that before proceeding in a questionable manner that the manufacturing plant be contacted for approval from Corporate Engineering of any methods different from these. A minimum clearance of 12 inches must be maintained between the lowest member of the main frame and the grade under all areas of the home. CAUTION: BEFORE GETTING UNDER THE HOME, MAKE ABSOLUTLY CERTAIN THAT IT IS ADEQUATELY SUPPORTED TO PRVENT A SERIOUS INJURY OR DEATH FROM AN ACCIDENTAL COLLAPSE OF THE HOME. 11 SINGLE WIDE SET-UP The jacking and blocking procedure is as follows: 1. After the home is located in its final position, level it front to rear by using the hitch jack. 2. Jack up one side of the home by placing one jack just forward of the front spring hanger and the other just behind the rear spring hanger. These two jacks must be operated simultaneously to raise the home. Install footings and piers; one just forward of the front jack and another just behind the rear jack (taking care not to exceed the correct spacing selected from Table 2). 3. Next, jack the mainframe beam at the front and position a pier within IV' of the end of the beam. At the completion of this step, this side of the home should be approximately level lengthwise. 4. Repeat steps 2 and 3 for the other side of the home. The home should now be roughly level from side to side. 5. Place remaining pier supports under the main frame beam on each side taking care to maintain maximum distance of no more than the spacing determined from Table 2, with piers located within IV' of each end of the beam. See Figure 4. 6. Level the home using a 6 foot carpenter's level, water level or similar equipment. The final height adjustment is obtained by jacking the main frame beam and placing hardwood shims between the piers and the beam, or other approved methods such as adjustable piers. The home will be adequately leveled if there is no more than 1/ inch difference between adjacent pier supports (frame or perimeter) and the exterior doors and windows of the home do not bind and can be properly operated. 7. Install additional edge piers as required. See Figures 4, and 5. This leveling process is important for appearance and is essential for the proper operation of doors, windows, and the drainage system. Excessive and/or non -uniform jacking during the leveling will cause the home to be racked or twisted. This may result in damage to the home. Care must be used during jacking and leveling to not distort the home. Check for proper operation of all doors and windows. Should the pier height need to be adjusted after the initial set-up, to compensate for any pier settlement, follow procedure in item 6 above. CAUTION: WHEN RELEVELING THE HOME, LOOSEN ALL THE TIE DOWNS PRIOR TO JACKING THE HOME. READJUST THE TIE DOWN TENSION AFTER RELEVELING IS COMPLETI W CL CL OCT 1 6 Federal Manufactured Home Construction And Safety standards 12 Your home is designed for a foundation system which supports the main frame beams. Nobility Homes does not recommend gLny support system which does not directly support the main frame beams as a primary system as this may result in damage to the home. Additional edge piers, as required by Nobility Homes are considered as a secondary part of the support system which must be included. CAUTION: CONSEQUENCES OF INCORRECT BLOCKING (Single Wide) Incorrect blocking and leveling of your home could produce a sagging home including but not limited to these related conditions. • Buckling and/or loosening of walls, partitions, siding, ceilings, doors, floors, linoleum, carpeting, insulation, wiring, sinks, tubs, toilets, weather stripping, and miscellaneous fixed original fixtures of the home. • Leaking windows, doors, roof, ceiling, walls, floor seams, and junctions. • Improper closing, binding and sagging of windows, cabinets and inside/outside doors. • Malfunctioning of plumbing; water outlets, lighting fixtures; electric heating and air conditioning systems. Upon completion of blocking and leveling, refer to Tie down and Anchoring Section on Page 22. Note: The symptoms listed above could also occur as a result of pier settle occurred follow the releveling procedure. C3 W MULTI -WIDE SET-UP 0 OCT 1 6 2008 M Set-up Instructions CL Federal Manufactured fl'I Home Construction Read these instructions completely through before starting set-up. "i And safety standards 1. Remove plastic covering and shipping strips from all sections and ends (if installed). Failure to do so may result in condensation problems. 2. Place sections close together (3 to 4 in.) with toter. 3. Set piers under "I" beam, locating them in accordance with the pier loading chart Table 2 and the accompanying notes. Also make provisions for required exterior wall, joint wall and/or end wall blocking piers. 4. Block and level the heavy section as per the single wide set-up instructions. 13 Remove the tires and then the axles and the tongue (if removable) and lower unit with jacks if necessary. The front piers may be temporarily located behind the tongue until the tongue is removed. 6. Using hydraulic jacks and come -a -longs, move the second section against the heavy section. Insert electrical connecting cables in raceways or junction boxes as necessary Refer to Figures 27, 28 and 29. CAUTION: SOME UNITS MAY HAVE ELECTRICAL INTERCONNECTIONS IN THE CENTER AREA OF THE UNIT. THESE SHOULD BE LOCATED AND PLANNED FOR AS THE SET-UP PROGRESSES. 7. Install mate -line gasket on the joint edge joists, lower part of the ridge beams and joint edge of walls. This material forms as air seal at the floor, ceiling and end walls. Refer to Figure 7. The gasket is designed to resist the entry of air, water, water vapor, insects, and rodents at all mate -line locations exposed to the exterior. S. Any gap between the two sections may be closed up by sliding the second section against the first using: (a) Greased paneling and winch or "come -a -longs", or (b) Other mechanical devices designed for this purpose. 9. Block and level the second section. Repeat Step 3 as necessary. Additional piers are to be installed under joint wall edge members under the sides of all openings in excess of 48 inches. Piers are to be placed (centered so as to equally support both edge joists). Additional piers are to be installed under exterior wall edge member at the sides of all door openings in excess of 32 inches. Additional piers are to be installed under end wall junctures. 10. Raise and wedge the outside of the second section to bring the roofs together. Check the alignment of the joint wall openings and ceiling. Refer to the Multi -wide Alignment Procedure Section, page 19. 11. If the tops of the end walls are not flush, refer to Figure 14 for flushing procedure prior to connecting the roofs together.

Make sure you have enough help to do the job; at least two experienced people. 2. Make sure you have the proper equipment. 3. If two people are working together, make sure you do things together. Especially in jacking and lowering the home. 4. When jacking the home up, never get under or between the beams!!! Stay clear so in the event it falls, you won't be pinned under it. 5. If you set your first blocks just behind the hitch, until you have it lowered, it will be a lot easier to get the hitch out. Then move the blocks up to the proper spacing using jacks. 6. When fastening the floors together, have someone inside to make sure they are even on top. This also holds true with the ceiling. Sometimes it is necessary to use a jack to level the ceiling before installing the screws. 7. If the floors are flush on both ends but the front top of one section is sticking out in front of the other section and the rear ends are the opposite, this will not let the ceiling line up. This must be corrected before the top is connected together. To eliminate this problem, put one jack under the outside front corner of the section sticking out. Place the other jack under the rear outside corner of the opposite section. Now jack up both corners at the same time until the ceilings line up. Then screw the center beam together before removing the jacks. See Figure 14. LU COCT 1 6 2008 CL CL Fedea! Manufactured Home Construction And Safety Standards IN Multi Wide Alignment Procedure (Double, Triple and Quad section) 1. Position and level the first section of the home per instructions. Excessive and/or non- uniform jacking during the leveling will cause the home to be racked or twisted. This may result in damage to the home. Care must be used during leveling to not distort the home. 2. Move the second section into position within 4 inches and alongside the first section. 3. Draw the two floors together using jacks, set at an angle at or near the outside spring shackles, or winches (come -a -longs). Figures 12 and 13. 4. With the two sections together, but with no fasteners installed, check the alignment of the end walls, interior walls, roof, and floor. Determine if the walls and/or the roof of either section must move backwards or forward with respect to the floor. Any corrections required can be accomplished during the leveling of the second section. 5. Alignment Procedure a) Position the second section to bring the floor seams flush, keeping the roof slightly apart and the end walls aligned at the floor. At this time place piers only on the inside frame beam. b) Close the gap in the ceiling by raising the outside frame beam using two hydraulic jacks placed ahead of and behind the wheels. c) IF THE TOP MUST BE MOVED FORWARD... With the frame support beams evenly supported, carefully raise the outside rear corner of the second section (and lower the outside front corner) with the hydraulic jacks. The roof should shift forward until the end walls comes even at the top. When the walls are even, raise the outside support frame beam evenly to close the gap. d) IF THE TOP MUST BE MOVED BACK... With the frame support beams evenly supported, carefully raise the outside corner of the second section (and lower the outside rear corner) with the hydraulic jacks. The roof should shift back until the end walls come even at the top. When the walls are even, raise the outside frame support evenly at the front and rear to close the gap. e) Fasten the top of the ridge beam together. When the top and walls are aligned and fastened, proceed with leveling of the second section. it7 71 If, ► LU OCT2008 `O 0 m 0. federal Manufactured Construction And Safety dards And 19 6. Alternate Alignment Procedure a) Position the second section so that the floors are together with the ceiling seam flush and the end walls and ceiling joints even at the top. Close the gap between the roofs by raising the outside frame support beam. b) With the ceiling positioned and the ridge beam halves snug, fasten the top of the ridge beam together. c) With the roof securely fastened, attach a winch (come -a -longs) between spring shackles of each section. Shift the floor and lower end of the walls into alignment by tightening the winch (Figure 13). d) Secure both floors together (refer to Figure 8).
