IT IS NOT INTENDED TO ENABLE SOMEONE UNFAMILIAR WITH MANUFACTURED HOME INSTALLATION TO PERFORM THE INSTALLATION. SET-UP SHOULD BE DONE ONLY BY QUALIFIED PEOPLE. WHOEVER DOES THE SETUP SHOULD GUARANTEE THEIR WORK IN WRITING FOR A REASONABLE TIME AND SHOULD, IF NECESSARY, AGREE TO RELEVEL THE HOME WITHIN 90 DAYS AFTER THE INITIAL SET-UP. CHAPTER 1 INTRODUCTION PLEASE READ ALL INSTRUCTIONS PRIOR TO SET-UP! This Skyline home was engineered, constructed and inspected for conformance to the Federal Manufactured Home Construction and Safety Standards in effect on the date of manufacture. This National Standard sets forth com- prehensive requirements for design construction, fire safety, plumbing, —heating —systems and electrical systems for manufactured homes designed to be used as dwellings. This manual contains detailed installation instructions, including specifications and procedures for erection and hookup of your manufactured home. It has been written in an objective and easy -to -understand manner so it can be understood by people without extensive technical training. It discusses the set-up of the home from preparing the site through final inspection. It includes many tables and figures giving important data for proper set-up. Careful adherence to this manual by the homeowner and installation crew, and consultation with a registered professional or structural engineer in those unusual circumstances it does not cover, will assure you of a quality, safe and affordable home for many years to come. Prior to locating or relocating your home, contact the local authority having jurisdiction for installation to see if permits for such procedures as blocking, anchoring, or utility connections are required. Inspections may be required dur- ing installation. On private property, zoning or development covenants may apply and should be taken into considera- tion. NOTE: Preparations of the site, when accom- plished by others than the home installer, may not be in accordance with these instructions. THE IMPORTANCE OF CORRECT SET-UP CANNOT BE OVEREMPHASIZED. Correct set-up is absolutely essen- tial to homeowner satisfaction. If you are not absolutely certain of the proper procedure or you encounter unusual conditions, please contact your factory service representative. THE INSTRUCTIONS CONTAINED HEREIN ARE MIN- IMUM REQUIREMENTS. APPLICABLE LOCAL OR STATE LAW MAY HAVE OTHER OR GREATER REQUIREMENTS WHICH MUST BE COMPLIED WITH TO OBTAIN OR REGAIN THE RIGHT TO OCCUPY THE HOME. REVIEWED BY ENGINEERING DEPT. ISSUED BY FOLLOW-UP SERVICES DEPT. MAY, 2002 UNDERWRITERS' LABORATORIES, INC. The recommended procedures contained in this manual are intended to assist in proper installation of this home. Field experience may justify alternate acceptable proce- dures which, when completed, result in performance at least equal to that which will result from conformance to the details and specifications herein. For example, on double wide installation you may find it advantageous, due to local conditions, to bolt the floors together prior to bolting roof halves together, or vice versa. Either method is acceptable as long as the bolting schedule is adhered to. NOTE: A MANUFACTURED HOME SET UP IN THE WRONG STRUCTURAL ZONE DOES NOT MEET THE REQUIREMENTS OF THE FEDERAL MANUFACTURED HOME CONSTRUCTION AND SAFETY STANDARDS. BEFORE COMMENCING SETUP, SEE CONSTRUCTION INFORMATION, LOCATED IN THE MASTER BEDROOM CLOSET OR AT THE ELECTRICAL DISTRIBUTION PANELBOARD, FOR DESIGNATION OF ZONE FOR WHICH THE HOME WAS CONSTRUCTED. SPECIAL CONSTRUCTION SUCH AS EXPANDO UNITS, TRIPLE WIDE UNITS, AND PERIMETER BLOCKED UNITS WILL BE COVERED IN SUPPLE- MENTS TO THIS MANUAL. CONTACT YOUR FACTORY OR DEALER IF THIS HOME HAS ANY SUCH FEA- TURES AND YOU DO NOT HAVE THE APPLICABLE SUPPLEMENTS. WARNING: ONLY TRAINED CREWS SHOULD INSTALL THE HOME. INSTALLERS SHOULD FOLLOW THE SAFETY INSTRUCTIONS PROVIDED IN THIS MANUAL. THIS HOME WEIGHS SEVERAL TONS USE ENOUGH- TEMPORARY WOOD BLOCKING TO SUPPORTTHE HOME DURING SETUP. No one should be allowed under the home unless it is securely in place, even if it is not mov 6u10rO, Iel T. tdMFe- The technical content of this Installation Manual has been reviewed by Underwriters' Laboratories, Inc. and found to'be in accordance with the Federal Manufactured Home Construction and Safety Standards. PROTECTIVE WINDOW COVERINGS (Continued) Protective coverings may also be installed over doors and sliding glass doors in a different manner than described previously. First, remove the mounting screws holding the door frame to the exterior wall. Then place the plywood (or wood frame) from Table 8 over the door opening and fasten the plywood and door frame back into the wall studs through the same holes in the door frame. Use #8 x 3" wood screws 12" o.c. for doors. Use #8 x 4" wood screws 6" o.c. for sliding glass doors. See Figure 8-6 for a typical application of this type of protective covering. —Door-Size ,See Table f /0 I STATE OF 'VDIANP`V\`� ,f //O N A L110\% �` SECTION B-B Plywood face / #8 x 3" Wood Screws grain / 12" o.c. max. #8 x 4" / Wood Screws 6" o.c. for a sliding glass door Fig. 8-6 Due to the limited time between when a storm warning is issued and when the storm could hit at your location, Skyline recommends that the items necessary for the protective coverings be purchased and prepared before a storm warning is issued. Cut plywood to size and mark it relative to window/door location. Store plywood and fasteners together in a dry place where it will be accessible. Once the protective coverings have been installed, the home should not be occupied. PROTECTIVE WINDOW COVERINGS (Continued) CHAPTER 2 DEFINITIONS 500 AIRPORT DR. MANSFIELD,TEXAS 76063 (817) 473-4421 Installation of Protective Covering as Required by H.U.D. for Zone II and III The following pages illustrate the application of an exterior window protection in the event of storms (such as hurricanes) as required by HUD. Please note: Installation of protective coverings (such as those listed below) will negate egress of the window. Homes with protective coverings (such as those listed below) cannot be occu- pied while the coverings are in place. Parts required:1. 3/4" plywood — enough for each window in the home. 2. #8 x 11/411 OR 11/2" wood screws (see below for quantity). The installation steps apply to both the vertical and horizontal sides of windows. The size of the window will affect the num- ber of fasteners needed. For windows with a face measurement of 30" wide x 30" high (or any smaller size), install 3 fasteners, spaced eight (8) to twelve (12) inches apart on the head and on the sill. Install four (4) fasteners, spaced eight (8) to twelve (12) inches apart on both the left and right frame sides. For windows larger than 30" x 30" with 46" x 60" being the maximum size, add one fastener to each side for each addi- tional eight (8) to twelve (12) inches in width and height. To determine the plywood size, (use 3/4" thick plywood) mea- sure the width and height of the return fin (edge to edge). Position plywood over the window. With plywood supported, drive one fastener through the plywood and window nailing fin near center of window sill. Repeat this procedure for the other required sill fasteners. With covering attached at sill, continue driving fasteners around perimeter of the plywood using the above spacing formula. After the storm has passed, reverse the above procedure to remove the covering. Store materials for future use. Be sure to fill all holes left by the removal of the screws with a suitable sil- icone type sealant. Material should have a long life rating. This will prevent water and air from entering the home.

All vegetation must be removed from under the home site. The site must be prop- erly graded and sloped to provide for storm drainage runoff. In particular, the area under the home must be graded to prevent water accumulation. Skyline Corp-mcommends-the— home site slope 10 feet in all directions away from the home. If the home is sited on sloping terrain or a hillside, the soil must be graded on all sides to channel storm runoff around the home and not under it. If the home is set in a pit, it is extremely important to provide water drainage from under and around the home. WARNING: THE AREA UNDER AND AROUND THE HOME MUST BE SLOPED TO PREVENT WATER ACCU- MULATION. EXCESSIVE MOISTURE UNDERTHE HOME CAN CAUSE UNNECESSARY DETERIORATION, AND CAUSE CONDENSATION PROBLEMS, WHICH COULD AFFECT THE HOME'S WARRANTY. IT COULD ALSO AFFECTTHE STABILITY OFTHE FOOTINGS AND PIERS WHICH SUPPORTTHE HOME. If the home is to be perimeter skirted or "pit -set," ventila- tion of the under -floor area is required to minimize the effect of moisture under the home. Ventilation openings must be provided in the under -floor enclosure or skirting on at least three (3) sides (preferable bn all sides) with a net area of at least one square foot per 150 square feet of floor area. The required ventilators are to be approximately equally spaced around the perimeter of the home with a ventilation opening --within-three (3) feet of each outside corner. Proper support of the manufactured home must allow for soil conditions in the immediate area. Pier footings must be placed on firm undisturbed soil (not loose fill) or soil which has been compacted to at least 90 percent of its maximum relative density. Support piers may also be placed directly on concrete slabs designed for manufactured home place- ment as found in manufactured home communities. After completion of grading and filling (if necessary), the bearing capacity of the soil at the depth of the footings should be determined. A pocket penetrometer (available from engineering supply houses) or other method accept- able to local jurisdictions may be used. If the soil cannot be tested but can be identified, Use the foundation bearing pressures shown in Figure 3-1 as a guide. If the soil cannot be identified, use the lowest value, 1,000 PSF. Under unusual conditions, or if the soil appears to be peat or uncompacted soil, consult a local geologist or professional engineer for aid. CAUTION EXCESSIVE WATER IN THE SOIL UNDER THE HOME WILL CAUSE UNNECESSARY DETERIORATION OF THE HOME AND AFFECTTHE COMFORT LEVEL IN THE HOME. CONTINUOUS STANDING WATER UNDER THE HOME CAN CAUSE CONDENSATION PROBLEMS AND AFFECT THE HOME'S WARRANTY.

''.f;ONAl���.`�' �, , FIG. 8-3 In the event of a windstorm, the corners of this home will sustain higher wind pressure than the rest of the home. Therefore, it is required that windows and doors located within 3 feet of any corner be designed to withstand these higher pressures. Figure 8-3 shows the typical locations of the corners. Table 8 has separate columns indicating the plywood requirements for standard wall area and wall area that is within 3 feet of a corner. After the windstorm is over and the plywood has been removed, all holes made by the screws in the 2 x 4s should be filled with a weather -resistant caulk. 5 54 CHAPTER 8 PROTECTIVE WINDOW COVERINGS If your home is destined to be set in Wind Zones II or III, then it has been designed to install protective window and door coverings, in the event of a windstorm.Two different types of protective coverings are available.Your home may have either, or both of these types. The first type of protective window covering is to attach plywood to a 2 x 4 member that has been installed around window and door openings. The plywood is attached to the 2 x 4 members with #8 wood screws. The type of plywood, screw length, and screw spacing will vary with the window or door size. See Table 8 for these requirements. Note that the window sizes listed in Table 8 are the small dimension of the window or door (See Figure 8-1). Large openings (such as sliding glass doors) are required to be covered with a plywood and lumber frame assembly.

C> IAPTER 4 FOUNDATION AND SUPPORT REQUIREMENTS NOTE: This chapter covers only foundations. Page 8 sum- marizes the usual types. Set-up procedures and methods for securing the home to its foundation are discussed in Chapter 5. A home that is certified for a higher roof load zone than the area that it is installed, may be set on a foundation system that is designed for the roof load zone for that area of the country. For example, a home that is certified to withstand a 30 PSF roof load is installed in a 20 PSF roof load zone area. The sup- port under the home need only be designed for the 20 PSF roof load, in accordance with the requirements set forth in this manual. PIERS Importance. Incorrect size, location or spacing of piers may cause serious structural damage to the home. It is important to install piers around the perimeter if required for the home. Failure to do so may lead to sagging floors, walls and roofs. Acceptable Types. Piers may be concrete blocks or pres- sure treated wood, capped and shimmed with wedges, or adjustable manufactured metal or concrete devices (see Figure 4-2). Manufactured piers should be listed and labeled for the required load capacity. DESIGN REQUIREMENTS Load -Bearing Capacity. The load that each pier must carry depends on factors such as the dimensions of the home, the roof live load, the spacing of the piers, and the way they are used to support the home. Center beam/marriage wall blocking is required for multisection homes. See tables 1 and 2 for pier capacities. Manufactured piers must be rated to at least these capacities, and locally con- structed piers must be designed to transmit these loads safely. Configuration. Figure 4-2 shows the recommended arrange- ment of concrete piers constructed on -site. Concrete blocks should have nominal dimensions of at least 8"x16". They must be stacked with their hollow cells aligned vertically. When piers are constructed of blocks stacked side -by -side, every layer should be at right angles to the previous one (See Figure 4-2). Cap hollow block piers as shown in Figure 4-2 to distrib- ute the structural load evenly across them. Caps may be of solid masonry or hard wood, and of the same length and width as the piers they rest upon. Avoid plywood, as it may lead to unwanted settling or movement. Use 4" x 6" hardwood shims (wedges) 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 (See Figure 4- Q 2). Drive them in tightly so they do not occupy more than 1" of vertical space. When the space to be shimmed is less than the minimum thickness of available caps or concrete blocks, dimension lumber may be used under the caps. Select manufactured pier heights so that their adjustable risers do not extend more than recommended by the man- ufacturer when finally positioned. All piers must rest on footings that either extend below the frost line or are otherwise protected from frost effects, and are placed on either undisturbed soil or compacted fill. DESIGN PROCEDURES Piers Less Than 36" High. Construct piers less than 36" high out of single, open or closed -cell concrete blocks, 8"x8"x16". Install them so that the long side is at right angles to the supported I-beam (See Figure 4-2). Position open cells vertically upon the footers. (See Figure 4-1). Horizontal offsets should not exceed 1/2" top to bottom. Mortar is not normally required. Manufactured piers should be listed and labeled. Do not extend their adjusting studs beyond the limits specified by the manufacturer. Piers 36" to 80" High. Construct all piers between 36" and 80" high, and all corner piers over three (3) blocks high, out of double, interlocked concrete blocks (See Figure 4-2). Mortar will not normally be required. Piers Over 80" High. Where permitted by local codes, lay them in concrete mortar with steel reinforcing bars inserted in the block cells and fill the cells with concrete. Where such construction is not permitted by local codes, have piers over 80" high designed by a registered professional or structural engineer. Location and Spacing. The location and spacing of piers depend upon the dimensions and weight of the home, the roof load zone, size, and type of construction of the footings. Other factors such as the location of doors or other openings and heavy pieces of furniture are also important. In general locate piers no more than 2' from either end, and not over 10' o.c. Single -Section Homes. Figure 572 shows the recommended locations and spacing of piers for single -section homes. Multi -Section Homes. Figure 5-3 shows the recommended location and spacing of piers for multi -section homes. Under Doors and Heavy Furniture. Place additional piers on both sides of exterior doors, side -wall openings wider than 4' (such as sliding glass doors), at Pavilion dormers, under porch posts, wood stoves, and under the expected locations of heavy pieces of furniture such as pianos, organs, waterbeds, etc. FOUNDATION AND SUPPORT REQUIREMENTS (Continued) DESIGN PROCEDURES (Continued) Footings. Support every pier with a properly designed foot- ing, as follows. ACCEPTABLE TYPES OF FOOTINGS. Concrete. Footings may consist of precast or poured -in - place concrete, pads, slabs, or ribbons with a 28-day com- pressive strength at 3,000 psi. Pressure -Treated Permanent Wood. Two layers of 2" thick pressure -treated wood planks, with the long dimension of the second layer placed perpendicular to that of the first, fastened and with cut edges painted or retreated, may also be used. Other Materials. You may also use other materials approved for this use by local authorities if they provide equal load - bearing capacity and resistance to decay. PLACEMENT IN FREEZING CLIMATES. Conventional Footings. For frost -susceptible soils, to pre- clude the harmful effects of ground frost heave, footings should usually be placed below the frost line. Consult local authorities to determine frost penetration. In the absence of a local code, use the frost penetration map as a guide. Floating Slab System. When properly engineered by a reg- istered professional engineer, compatible with the anchorage requirements of Chapter 5, and acceptable to the local author- ity having jurisdiction, a "floating slab system" may be used above the frost line. Insulated Foundations. Footings may also be placed above the frost line when the home is provided with a perimeter foundation or skirting having insulation properties sufficient to prevent freezing of the soil under or adjacent to every load -bearing component of the foundation and accept- able for this purpose by the local authority having jurisdic- tion. Useful design guidelines may be found in references at the end of this chapter. Insulation systems should be compatible with the requirement to cross ventilate the entire space under the home. Proper Sizing of Footings. Proper sizing of footings depends upon the load -carrying capacity of both the piers and the soil. See Table 4 ford recommended footing sizes. See Table 4B for minimum required concrete footing thick- ness. Footing size in no case shall be less than 144 sq. in. or smaller than the pier it supports. Permanent Foundations. Check local building codes and regulations and consult a registered professional or struc- tural engineer when you are setting your home on a per- manent foundation (such as a full basement, crawl space or load -bearing perimeter foundation). A permanent foundation design, which meets most local codes, may be available from Skyline Corporation. Please contact the Skyline division which manufactured the home or Skyline's National Director of Consumer Relations. Flood -Prone Areas. Skyline Corporation does not recom- mend locating homes in river or coastal flood -prone areas. Special elevation and anchoring techniques are required when locating in a flood -prone area. Consult a registered professional or structural engineer to make sure that the home design and construction conform to applicable federal; state and local codes and regulations. The FEMA publication listed below contains design and construction recommen- dations. Severe Wind Areas. Special foundation and anchoring techniques are required when locating in a severe wind area is unavoidable. Consult a registered professional or structural engineer. The HUD foundations design guide referenced herein contains recommendations for designing foundations and anchoring systems. Do not place your home in a wind zone more severe than the one indicated on the data plate located by your home's main electrical panel. Special Snow Load Conditions. Homes designed for and located in heavy snowfall areas or subject to other extreme loading conditions may require special piers or footings. See tables and/or special manufacturer's instructions provided with your home.

The electrical supply connection to the manufactured home may be made by any of the following methods depending on the manufactured home construction and electrical service: a. Listed 50 ampere manufactured home power supply cord..-(50-amp-service-only)— — - b. Permanent feeder connected to a factory installed mast weatherhead assembly. The routing, connection and support of the service drop is to be in accordance with local codes. c. Permanent feeder routed to the distribution panel through the factory installed feeder raceway which ter- minates beneath the manufactured home. A junction box or approved fitting must be used to connect the manufactured home feeder raceway to the supply raceway beneath the manufactured home. The proper feeder conductor sizes and the required junction box sizes are given in Table 7. After the connection has been made, the following tests should be conducted using approved test equipment: 1. Continuity test of circuit conductors 2. Polarity test 3. Continuity test of electrical grounding system OUTSIDE DISTRIBUTION PANEL BOARD Accessibility to distribution panel board, and the use of unit switches as disconnect means, is subject to the re- quirements of the local inspection authority. ELECTRICAL SYSTEM TEST With approved testing equipment, the following tests should be performed before connecting to the power source: -- - • Continuity Test of Circuit Conductors A continuity test with all branch circuit breakers and switches controlling individual outlets in the "on" posi- tion should be conducted. There should be no evidence of connection between any of the supply conductors (in- cluding neutral) and the grounding circuit. • Continuity Test of Electrical Grounding System All noncurrent carrying metal parts of the electrical system including fixtures, appliances and the chassis of the home should be tested for continuity with the grounding circuit. The following test should be conducted after connec- ting and energizing the electrical system. • Polarity and Grounding Tests of 15 and 20 AMP Recep- tacle Outlets With circuits and lighting circuits energized, use a receptacle polarity tester to check polarity and ground- ing of each receptacle outlet.

WARNING CARELESS INSTALLATION OF TELEPHONE AND CABLE TELEVISION LINES MAY BE HAZARDOUS. The manufactured home walls contain electrical circuits and the floor section may contain electrical circuits, plumbing or duct work. Extreme care must be exercised during drilling through and placing of communication cables within these cavities, to avoid contact with these home systems. Such work should be performed only by qualified personnel. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH. SOURCE: U.S. Dept. of Commerce Weather Bureau FIG. 4-2 0 Fn UTILITY SYSTEM CONNECTION AND TESTING (Continued) The gas piping system was pressure tested for leaks prior to shipment; however, it is essential that the system be retested by qualified personnel for leaks prior to use. (Many utility companies require this on -site test.) The in- structions printed on the tag near the gas supply connec- tion must be followed (See Fig. 7-1). In some localities, utility companies and/or building in- spectors -may -require additional tests as follows: 1. Isolate all appliances with appliance shutoff valves. PRESSURE SHALL BE MEASURED WITH A MER- CURY MANOMETER OR SLOPE GAUGE CALI- BRATED IN INCREMENTS OF NOT GREATER THAN 1110 POUND. 2. Pressurize the system to 3 psi and isolate the source of pressure from the gas piping. 3. Check the gauge after 10 minutes; there should be no drop in pressure. 4. Check the piping to appliances by pressurizing to at least 10 inches but no more than 14 inches water col- umn and applying a bubble solution to all joints and flexible connectors. CAUTION: DO NOT PRESSURIZE THE SYSTEM ABOVE THE PRESSURES STATED ABOVE. The connection to the gas supply should be made only by authorized representatives of the utility. NOTE: BEFORE A TEST IS BEGUN, THE TEMPERATURE OF THE AMBIENT AIR AND OF THE PIPING SHOULD BE APPROXIMATELY THE SAME — CONDUCT THE TEST AT SUCH A TIME DURING THE DAY WHEN AIR TEMPERATURES WILL REMAIN CONSTANT. Combination LP —Gas and Natural Gas System This gas piping system is designed for use of either liquefied petroleum gas or natural gas. NOTICE: BEFORE TURNING ON GAS BE CERTAIN APPLIANCES ARE DESIGNED FOR THE GAS CONNECTED AND ARE EQUIPPED WITH CORRECT ORIFICES. SECURELY CAP THIS INLET WHEN NOT CONNECTED FOR USE. When connecting to lot outlet, use a listed gas supply connector for manufactured homes rated at ❑ 100,000 Btuh or more. ❑ 250,000 Btuh Before turning on gas, make certain all gas connections have been made tight, all appliance valves are turned off, and any unconnected outlets are capped. After turning on gas, test gas piping and connections to appliances for leakage with soapy water or bubble solution, and light all pilots.

See Table 4 for minimum footing sizes based on pier loads and allowable soil bearing capacities. The footing sizes and pier loads are minimums required for the applicable conditions. The footing shall not be smaller than the pier it supports or 144 square inches. 2. The maximum spacing of supports is not to exceed 10 feet. 3. Where it is impractical to maintain spacing, such as in the axle area, the average of the distance to each adjacent support may be used to determine support requirements. For example: if the distances to the adjacent supports were 6'-0" and 8'-0", the average spacing would be 7'-0". 6'-0" 8'-0" I< >I< >I Pier A Pier B Pier C The average spacing for pier B would be (6 + 8) / 2 = 7 ft., therefore, pier B would be designed for 7 ft. pier spacing. 4.

Multiply this number by the span a pier is carrying to determine the required capacity of that pier. CHAPTER 7 UTILITY SYSTEM CONNECTION AND TESTING Many local jurisdictions have special requirements for utility connections and on -site inspection of these connec- tions. Consult with the proper authorities prior to utility con- nection. Use only qualified service personnel, familiar with local codes and licensed where required. The drainage and water systems were tested for leaks prior to shipment from the factory. It is essential that they be rechecked by qualified personnel for leaks that may have been caused by vibration during transportation. WATER The water system has been designed for an inlet water pressure of 80 psi. If the manufactured home is installed in areas where the water pressure exceeds 80 psi, a pressure reducing valve should be installed. The water system may be connected to any safe, potable water source. The connection is via a single 3/4 inch inlet beneath the home. A master shut-off full flow valve must be installed in the water supply line adjacent to the home; this valve should be a full port gate or ball valve with threaded or solderjoints. After removing the aerators from all the faucets, open all the faucet valves and allow the water to run for 15 minutes. This should remove any foreign particles left in the line that might cause an unpleasant taste or become lodged at faucet washers and cause dripping faucets. All exposed water piping subject to freezing should be protected by in- sulation and electric heat tapes (with an integral thermostat) listed for use with manufactured homes. It is recommend- ed that only UL listed heat tapes be used and installed in accordance with their installation instructions. DRAINAGE — CONNECTION The drainage connection is made at the 3-inch main drain outlet. Care should be exercised to slope and sup- port the drain line from the home to the site sewage system (1/4" per foot slope). DANGER: IMPROPER OR INADEQUATE TESTING, CON- NECTION OR MODIFICATION OF ANY PART OF GAS OR ELECTRICAL SYSTEMS, ESPECIALLY BY UNQUALIFIED PERSONNEL, MAY BE EXTREMELY DANGEROUS AND MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH. DRAINAGE —1, 1%, 13/4 & 2 BATH When applicable the parts required to bring all drain lines to a single point are provided as follows: 1. Pipe and fittings. 2. 1/4 pint of ABS solvent cement. 3. 10 feet of 3/4" x 2B gauge plumbing strap. 4. Ten 1/4" x 1" stove bolts. The procedure for bringing all drain lines to a single point is as follows: 1. Remove caps on drain outlets and connect supplied parts together as shown by the drain line schematic shipped with the house. (Do not apply cement.) 2. Check to be sure that the assembly has the proper 1/4 inch drop per foot. 3. Mark each joint to aid in reassembly. Start at outlet end of system and remove, cement and reassemble each slip joint one at a time. Be sure to apply the cement on both male and female ends with a good even coating. 4. Using the 3/4" x 28 gauge strapping, strap the drain line to the center crossmembers of the frame placing a strap at each member (4 feet apart). Use a 1/4" x 1" stove bolt to secure strap in place. 5. Connect home drain to site sewage system as for single bath previously discussed. 6. Check completed system for leaks. GAS — The gas piping system was designed for a range of 7 to 101/2" of water column for natural gas and 11 to 14" of water column for LP gas. The manufactured home gas supply pressure must be within this range for safe and effi- cient operation of the gas piping system. 48 INSTALLATION OF OPTIONAL FEATURES (Continued) FIELD INSTALLED TERMINATION OF FIREPLACE CHIMNEY.

CAUTION: THE HOME WEIGHS SEVERAL TONS. USE ADEQUATE TEMPORARY SUPPORT BLOCKING TO SAFEGUARD WORKERS. SKYLINE, CORP. RECOM- MENDS WOOD BLOCKING. Positioning Home. When not placing the home on a con- crete slab or poured -in -place footings, mark the corners of the home and lay out footings and support devices close to where they will be used. Then move the home or first sec- tion into position. Leveling and Blocking — Single -Wide Homes. 1. Before doing any jacking, place support piers for the home in the locations under the home as specified in the home installation instructions. 2. Use a minimum of two jacks, each with a rating of at least ten tons. 3. Jack only on the main chassis I-beam. Locate the jack directly under the vertical web of the I-beam. Do not jack on the seam Qoint between flanges) of a twin I-beam. 4. Use a large 3/8 inch thick steel plate, C-channel or other equivalent plate between the main chassis I-beam and the jack head to distribute the load. 5. The jack base and any blocking must be located on firm ground. 6. Do not operate the jacks while you are under the main I -beams of the home. 7. Use jacks only for raising the home. Do not rely on the jacks to support the home. 8. Place 4" x 6" X 48" min. safety timbers between the I -beams and ground in case of jack failure. Timber should be hardwood. 9. Raise the home in small increments and provide addi- tional blocking between the home and the piers and safety piers as the home is raised. FAILURE TO FOLLOW THESE WARNINGS MAY RESULT IN SERIOUS INJURY OR DEATH. Reminders before jacking... 1. Use only jacks in good condition with a minimum rating of 10 tons. 2. Use a minute man C-Channel jacking plate or equivalent between jack and steel I-beam to distribute the concen- trated loads. (See Figure 5-1) 3. Use a firm support under the jack base to prevent tipping or settling of the jack. Skyline recommends a 12" X 12" or larger pad. 4. Always follow the sequence of jacking outlined below to avoid overstressing structural members.

THE COMPLETED INSTALLATION MUST CONFORM TO ARTICLE 440 OFTHE NATIONAL ELECTRICAL CODE AND APPLICABLE LOCAL CODES. Factory installed branch -circuits for air conditioning are in- dicated on the data plate under the heading "Rating of Factory Installed Circuit"The maximum full load ampere draw for the desired air conditioning unit must not exceed the indicated branch circuit rating. "A" coil air conditioning units installed must be listed for use with the furnace in this home; for air condi- tioning installation, see the instructions shipped with the air conditioner. If a self-contained air conditioner is to be installed and connected to the heating supply duct the installation must include a damper beneath the furnace to prevent cool air from "backing -up" into the furnace during the cooling mode and a damper at the air conditioner supply to prevent heated air from "backing -up" into the air conditioner during the heating mode. It is recommended to wrap the dampers with insulation. The electrical connection is via a branch circuit terminating in a junction box beneath the home (See Fig. 6-3). The field installation wiring beyond the junction box must incorporate a fused disconnect (sized in accordance with NEC Article 440) located within sight of the condensing unit.The maximum fuse size -to -be -used with the fused_ disconnect is marked on the condenser data plate. The acceptability of the air conditioning equipment, rating the location of disconnect means, fuse type branch circuit protection, and connections to the equipment are to be determined by the local inspection authority. For some models the electrical connection is made to the home via a separate rigid conduit.The conduit is 1" and is run from the panelboard and terminates below the bottom board. A PVC cap is cemented to the end of the conduit and this must be cut off to provide access to the panel board. Wiring is then installed from the panelboard to the air conditioner per all applicable NEC & local codes and all requirements listed above. Condensation should not be allowed to drain under home.

After the home is located in its final position, you can preliminarily level it by using the hitch jack but only after adequately wheel blocking the home so it does not roll. 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. Jack low side of the home first. 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 1 or 2). 3. Next, jack the main I-beam at the front and position a pier within 2'-0" of the end of the I-beam. At the completion of this step, this side of the home should be approximately level. 4. Repeat Steps 2 and 3 for the other side of the home. At the completion of this step, the home should be roughly level from front to rear and from side to side. 5. Place the remaining pier supports under the main I-beam on each side taking care to maintain a maximum distance of no more than the spacing determined from Tables 1 or 2 with piers located with 2'-0" of each end of each I-beam. (See Fig. 5-2) 6. Level the home within reasonable tolerances, using a 6 foot carpenter's level, water level, or similar equipment. The final height adjustment is obtained by jacking the I-beam and placing hardwood shims between the piers and I-beam, or other approved methods such as adjustable piers. THIS LEVELING PROCESS IS IMPORTANT FOR APPEARANCE AND IS ESSENTIAL FOR THE PROPER OPERATION OF DOORS, WIN- DOWS, AND THE DRAINAGE SYSTEM. 7. Place additional supports at each side of sidewall door and window openings over 4'0" wide. (See Table 3A) 8. Within 90 days after initial set-up, the home should be releveled, if necessary, to compensate for any pier set- tlement. Follow the procedure in Item 6 above.

To complete the moisture -lint exhaust system the following must be performed: t. Remove the covers over the vent hole in the floor. 2. Push the duct through the hole provided in the floor and connect to the dryer in accordance with the dryer manu- facturer's instructions. NOTE: Some dryer manufacturers require that metallic duct be connected to the dryer and routed through floors and/or sidewalls. 3. Secure the termination fitting at the outside edge of the floor. NOTE: The termination fitting must be installed such that the dryer does not exhaust beneath the home.This may be accomplished by attaching the fitting to a piece of exterior grade plywood or, if the home is skirted, directly to the skirting. 4. Secure the flexible duct to the termination fitting with the provided clamp. (Do not use sheet metal screws or other devices which extend into the interior of the duct.) 5. Seal the duct penetration through the floor with a good grade of caulking. CAUTION: MATERIALS WHICH MAY BE PROVIDED FOR THE MOISTURE -LINT EXHAUST SYSTEM ARE NOT ACCEPTABLE FOR INSTALLATION OF GAS DRYERS. Homes factory equipped with a gas dryer will also have the moisture -lint exhaust duct and termination fitting pro- vided. To complete a roughed -in system follow steps 1-5 under Electric Dryer Venting. Homes with "stubbed -in" gas service will also have the moisture -lint exhaust system roughed -in. However, the ex- haust duct and termination fitting are not provided. Such termination fittings should be supplied with the dryer at time of installation. The gas connection and completion of the moisture -lint exhaust system must be made by qualified personnel in accordance with the dryer manufacturer's installation instructions. The gas connection must be tested (See Utility Hook-up and Testing) prior to use of the appli- ance. To complete the moisture -lint exhaust system, follow steps 1-5 under Electric Dryer Venting. GRILL/RANGE VENTING When a home is provided with a combination range (cook top)/grill that contains its own exhaust system, the exhaust must be routed such that it does not terminate beneath the home. To complete the exhaust system the following must be performed: 1. Remove the cover on the factory installed exhaust pipe protruding from beneath the floor in the vicinity of the range. 2. Secure the provided termination fitting at the outside edge of the floor. 3. Run the provided flexible metallic duct between the elbow protruding from the floor and the termination fit- ting. Support the duct and make the connections per the manufacturer's installation instructions provided with the grill/range. GAS WATER HEATER VENTING Homes factory equipped with certain types of gas water heaters may require special provisions to ensure proper ventilation. If the gas water heater installed in your home is not independently vented to the exterior of the home through a grilled opening in an exterior water heater door, then the following provisions must be followed. A. If the home is set on a crawlspace, or piers and skirting are used, then an air intake opening with a minimum free area of 32 square inches must be provided in the foundation wall or skirting. If the opening is covered by louvers or screen, the total free area must be 32 square inches. The air intake opening should be located as close as practical to the water heater location. B. If the home is set on a basement, then the following steps must be taken: 1. Fabricate a plenum box to encompass the air inlet assembly without alteration to the air inlet assembly itself. This plenum must have a minimum horizontal dimension of eight (8) inches. The minimum clearance between the air inlet assembly and the inner wall of the plenum shall be two (2) inches. The vertical height of the plenum shall be as necessary to ac- commodate the air inlet assembly without alteration. The air inlet assembly is a round tube that is extended from the bot- tom of the water heater through the floor. 2. To ensure proper air entry into the fabricated plenum box, a 6 inch minimum round (or equivalent cross -sectional area) duct is required. The duct shall be of a smooth surface, rigid variety (no flex pipe) and shall be connected to the plenum in a manner that does not reduce the cross sectional area of the pipe. 3. The air inlet shall be of damperless type and provide a free area not less than the cross -sectional area of the duct. A screen, if used, shall be 1/4 x 1/4 inch minimum.

Install the bulb. NOTE: SOME LIGHTS WILL USE TWO BOLTS WHICH THREAD INTO THE MOUNTING STRAP IN LIEU OF THE THREADED ROD ILLUSTRATED VENTILATION OF SKIRTING AND CRAWL SPACE ENCLOSURE Skirting or other crawl space enclosures, such as foun- dations, not only add to the appearance of the home but also provide important benefits in the reduction of heat loss. Enclosures also aid in reducing the danger and inconve- nience of damaged plumbing through freeze-up. Skyline Corporation recommends enclosing the underside of the home; however, it is very important that any enclosure be adequately ventilated. Ventilation openings need to be provided in the foundation or skirting along at least the two long walls of the home. The total area of ventilation openings should be at least 1 square foot for each 150 square feet of crawlspace area. An opening should be located within 3 ft. of each corner. PORCHES AND DECKS Some Skyline manufactured homes are constructed with factory -built porches or decks along the front, rear or main entry door side of the home. Porches and decks may be constructed with pressure treated wood floors which readily permit the passage of rain and/or snow through the floor. The area under porches or decks constructed with pressure treated decking lumber must be separated from the crawl space enclosure of the remainder of the home. Excessive moisture in the crawl space can be the cause of window or ceiling condensation and other problems associated with high moisture levels in the home. 19 W SET-UP PROCEDURES (Continued) UTILITY INTERCONNECTION 4.

In areas where exposed piping is subject to freezing, protect exposed piping with heat tapes listed for use on manufactured homes, and insulation. It is recom- mended that only U.L. listed heat tapes be used and installed in accordance with their listing. SETUP PROCEDURES (Continued) DOUBLE -WIDE INTERCONNECTION The procedure for connecting the homes is as follows. 1. Remove the temporary closure materials (polyethylene and batten strips) and position the halves as close to- gether as possible in the final desired location. Do not remove temporary beam supports until step 7 has been completed. 2. Move the first section of home into its desired position. Block and level it in the same manner as described for a single section home. Skyline Corp. recommends, if possi- ble, the heavy half be blocked and leveled first as it is eas- ier to lift and roll the light half and fit into place. 3. Install sill sealer insulating material (provided) around the ceiling (to the ridge beam at the ceiling panel line), end - walls and floor mating line. Fasten sill sealer with staples or nails. See Figure 5-8A. 4. Slide the two halves together with rolling and jacking equipment. Care must be taken during rolling and jacking operations to avoid overstressing structural members. With the halves together at the floor, align the floors at the ends of the home. It is better to have a minor misalign- ment under the siding where it cannot be seen and will not cause a problem, than a small misalignment that will be observed in the interior of the home. 5. With the home aligned at the floor and supported by its foundation, join the floors using 3/8" x 2-1/2" (4-1/2" lags with double perimeter joist) lag screws 2 to 3 feet on center. The centerline gap at the floor should be a maxi- mum of 3/16" Use the procedures outlined on page 16 to level the home and check supports and footings with ta- bles 2 and 3. 6. To obtain access into the ceiling cavity to bolt or alter- nately lag screw the ridge beam sections together, fold back the underlayment paper and remove the 16" wide sheathing panel(s) at the peak. Note that the shingles may not have been installed on one or both halves, at the 16" wide area at the peak. If one side is shingled, it is intended that the beams be lag screwed together. If nei- ther side is shingled, the beam may be lag screwed or bolted together. Bolts to be 3/8" x 4-1/2" at 48" o.c. with 3 additional bolts at 3" o.c. over interior beam supports. Lag screws to be 3/8" x 5" at 24" o.c. with 6 additional lag screws at W o.c. over interior beam supports. (If marriage walls and ridge beam halves have been plated with 3/8" sheathing, then the bolts/lags must be increased in length by 3/4" to 5-3/4".) Predrill 1/4" pilot holes for the lag screws at 1-1/2" down from the top of the beam and with a max- imum offset from the horizontal of 45 degrees. A gap be- tween beam halves up to 1" is allowable. Gaps larger than 1/2" must be filled with plywood or lumber shims. For 1/2" max gaps, increase fastener length 1/2". For 1" max. gaps increase fastener length 1-1/4". See Fig. 5-7.

Prior to interconnecting the ridge beam halves, examine the ridge beam ends. Should there be a slight misalign- ment, it can be eliminated by placing a jack under the low side of main beam on one half and use the jack to raise the beam. The alignment can be held by properly bolting or lag screwing the beam halves together. See Fig. 5-8. 8. Place additional pier supports at the centerline at the interior column locations marked on the floor with indica- tor straps or paint (see Figure 5-3 and 5-4 and Table 3). Skyline Corp. provides pier location diagrams for all multi - wide models. These diagrams show the required loca- tions of piers and are very useful in determining pier placement prior to taking receipt of home. Additional piers are required each side of exterior doors and sidewall openings greater than 4' in width. See Table 3A for these pier load requirements. 9.

Note: If unit has multiple cable splices the circuits will be identified by the attached code markers. Heating Crossover There are two basic hookup procedures for all designs. The first procedure is the standard design and is a single 12" diameter flexible duct. The second procedure is an optional design that includes a varying number of 5" or 6" crossover ducts that are installed in the floor. The method of installation for the standard design is as follows: 1. Connect each end of the provided insulated 12" diame- ter flexible duct to the metal duct connector on each half of the home by sliding duct over metal tabs on duct connector. 2. After mechanical connections are made, tape each con- nection with 2-inch wide duct tape to ensure an airtight seal. 3. Permanently secure the crossover duct with straps as shown in Fig. 5-29. Do not allow duct to rest on the ground. Maintain at least a 4-inch clearance between duct and the ground. The method of installation for optional design with stan- dard frame is as follows: 1. Remove access panels at crossover ducts. The access panels are located below the floor. 2. Cross cut bottom board at 8" holes in reinforcing plates. 3. Extend the flexible ducts from each half through the access holes (See Fig. 5-29A). CROSSOVER DUCT FIG. 5-29 DUCT NOTES: 5 STRAPS AS SHOWN TO FLOOR JOISTS.

SETUP PROCEDURES (Continued) MANUFACTURED HOME TIE -DOWN INSTRUCTIONS The support system must also resist lifting, sliding, and overturning forces resulting from side winds. A method used is to install ground anchors and tie -down straps in addition to the piers. Tie -downs as described are the minimum nec- essary if the home is to withstand its design loads without dislocation. On multi -section homes, sections must be fas- tened together and level before tie -dawn straps are installed. WARNING BEFORE GROUND ANCHOR INSTALLATION, DETER- MINE THAT THE ANCHOR LOCATIONS AROUND THE HOME WILL NOT BE CLOSE TO ANY UNDERGROUND ELECTRICAL CABLES, WATER LINES OR SEWER PIPING. FAILURE TO DETERMINE THE LOCATION OF UNDERGROUND ELECTRICAL CABLES MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.' NOTE: IN THE FRAME TIE -DOWN SYSTEM, IT IS Ili TANT TO USE MATERIALS OF PROPER DESIGN AND OF ADEQUATE QUALITY. THE MATERIAL SPECIFICA- TIONS CONTAINED HEREIN SHOULD BE CONSIDERED AS MINIMUM REQUIREMENTS. Materials not furnished with the home which will be nec- essary to complete the tie -down system must meet the re- quirements set forth below. Such materials would include: 1. Cable or steel strap with a breaking strength of at least 4,725 pounds e.g. galvanized aircraft cable at least 1/4" diameter orType 1, Finish B, Grade 1 steel strapping 1-1/4" wide and 0.035" thick, conforming with ASTM D3953-91. 2. Galvanized connection devices such as turnbuckles, eyebolts, strap buckles, and cable clamps should be rated at 3,150 working load minimum. 3. Ground anchors - capable of withstanding at least a 4725 pound pull. Anchors must be installed as specified by the anchor manufacturer. Stabilizers or concrete col- lars may be required by anchor manufacturer. THE HOME MUST BE IN ITS FINAL LEVEL POSITION PRIOR TO TYING IT DOWN. The procedure for tying down the manufactured home is as follows: 1. Position and install the ground anchors under exterior walls so that the final strap angle and height (H) will be within the limits shown in tables 5 thru 6C. 2. Connect the straps to the frame and ground anchors (See Figs. 5-9 and 5-10). Straps wrapped around the (- Beam as shown in Fig. 5-9 require protection from pre- mature failure due to sharp corners. Fig. 5-9A illustrates one method to protect against sharp corner damage. Other methods (such as beam clamps - Tie -Down Engineering part no. 59003 or equivalent) approved by the local building authority having jurisdiction may be used. 3. Tighten the straps using the tensioning device provided with the ground anchors. Use caution to avoid overten- sioning the straps which might pull the home off the piers. It is recommended that all straps be tightened only enough to remove slack. Then, after all straps are installed and the slack removed, tension the straps. 4. The strap tension should be rechecked at frequent inter- vals until all pier settlement has stopped. CAUTION: DURING THE RELEVELING PROCESS, DO NOT JACK THE HOME AGAINST TIGHT STRAPS. Protect sharp comers with 26Ga. (0.019" min.) x 2" galvanized steel strapping material formed to fit around beam flanges. Sharp come protection at top and bottom of beam if strap is wrapped around beam.

HardiPanel Application FIG. 5-20 25 Rd SETUP PROCEDURES (Continued) DOUBLE -WIDE EXTERIOR CLOSURE VINYL LAP SIDING Apply a 2" wide strip of duct tape at the marriage joint of the endwalls for the entire height of the walls. Apply the duct tape directly over the sheathing. The siding panels should be attached using galvanized steel or aluminum 16 ga. 1/2 by 1" staples. (6d galvanized nails may also be used). Staples should be driven so that there is -a 1/32" clearance between the siding and -staple crown to allow some lateral movement. Fasten every 16" at the stud location. See Figure 5-19 Detail A for proper fastening. Snap the bottom course of siding into the starter strip and fasten to the wall. Leave a 1/4" space at corner posts and'J' channels around window and door openings to allow for expansion. Do not fasten within 4" of an accessory. Vertical butt joints in panels should overlap 1 ". Do not fasten the panel within 4" of the joint. Install vinyl, aluminum, felt or other suit- able material for flashing at bottom corners of doors and windows per Figure 5-19 Detail E. Apply caulk around siding and light blocks, water faucets, or other small penetrations. Install successive courses similarly to the first. Butt joints in adjacent courses should be offset by aty least 24". Joints in alternate courses should be aligned vertically (See Figure 5-19 Detail B). Panels will have to be cut at headers and sills. A single panel should extend without joints across the width of the opening. When cutting a panel at a sill, measure the dis- tance between the bottom of the opening and the top lock of the lower course, then deduct 1/4" (See Fig. 5-19 Detail C). Slide the cut panel into the under sill trim and install. Note that the under sill trim piece may have to be furred to main- tain the proper pitch of the siding. Measure and cut the header panel in the same manner as indicated above. The top sections at the gable will need to be angle cut. Use two scrap pieces of siding to make a pattern (See Fig. 5-19 Detail D). Interlock one piece with the siding panel below. Hold the other piece on top against the gable. Mark a line on the bottom piece and cut. Use this piece as a pattern for cutting gable pieces. Install the gable pieces by inter- locking with the lower course, sliding into the gable 'J' rail and fastening.

This criteria is as follows: 1. Width of the home. 2. Main I-beam spacing of the home. 3. Wind-Zone-areawherehome is to be placed. 4. Distance from bottom of I-beam to ground. 5. Torque reading of the soil. 6. Nominal roof pitch of unit (for double-wides). For this example assume the home being installed is a 14 foot wide (single -wide) by 66 feet long. The home is being installed in Wind Zone I, and the main I-beam spacing has been established at 99-1/2 inches. The home has a 12 inch tall I-beam, and the clearance from the I-beam to the ground is measured at 20 inches. To determine the distance (H) from the ground to the underside of the floor add the I-beam depth (12") to the clearance between I-beam and the ground (20'). Therefore H = 12" + 20" = 32". From Table 5 on page 22 (Wind Zone 1) determine the maximum allowable strap spacing. Enter table at left hand side for 14' wides, and check the maximum pier height (H) for 99.5" I-beam spacing. H max. = 35" with straps/anchors spaced at 12' o.c. maximum. Therefore, tie -down strap spacing should not exceed 12 foot on center. If the home were placed in a Wind Zone II or III area, the tables on pages 26 or 27 would be used. Next, determine the correct soil anchors to be used. An anchor soil test probe is required to test the soil where the example home is to be set. The soil test probe looks like_a long drill bit with a fitting at the top which accepts a torque wrench. The torque required to turn the probe, when the probe reaches the desired anchor depth is measured. The anchor manufacturer provides a chart relating the measured torque value to the type of anchor required to provide the desired holding force. AN INCORRECTLY SELECTED ANCHOR WILL NOT PROVIDE THE REQUIRED LOAD RESISTANCE. For this example, assume a torque of 300 inch -pounds was measured at a probe depth of 4 feet. A class 4 soil is indicated from the anchor manufacturer data. The correct anchor would be identified and rated for a class 4 soil. Soil anchors must be installed as directed by the anchor manufacturer. If the direction of the pull is not in line with the shaft of the anchor, a concrete cylinder collar or a ground anchor stabilizer plate is required. The anchor manufacturer installation instructions should describe the correct anchor placement with regard to direction, water table level and frost line location. Sidewall straps are factory installed. Z Ground anchor (typical).
