PLAN SITE ACCESS Planning the route to the site is typically the responsibility of the retailer or transporta- tion company. Whoever is responsible must secure state permits from the states through which the home will pass. In planning the route, avoid obstructions that might interfere with the passage of the home, such as low hanging wires and trees, low overpasses, and bridges not suitable for the load. Contact the utility company if wires need to be moved. Do not allow branches, bushes, or other foliage to scrape against the home as the home is moved to the site. Avoid ditches, berms, steep slopes, and soft ground. Identify and fill any holes and soft spots into which the transporter's wheels may sink. Avoid moving over steep changes in grade (20 degrees or more). If required, provide for home storage and staging areas on the site. Plan the delivery and staging of home sections and materials so that after all deliveries are complete, home sections and materials can be accessed for use and installed in the appropriate sequence. Orient home sections so they do not have to be rotated or excessively ma- neuvered during the installation process. Plan for temporary needs, such as dump- sters, portable toilets, crew parking, delivery vehicle drop-offs and concrete mixer de- liveries. Before moving the manufactured home to the site, inform the IAHJ and make sure the site is prepared and utilities are available. STEP 2. DETERMINE HOME LOCATION AND LAYOUT The home location may have already been determined by others_ If not, plan the home location and layout in compliance with the regulations researched in Getting Started, STEP 5. CHECK LOCAL CODES AND SECURE PERMITS (p. 8). Contact utilities for locations of existing infrastructure, such as underground cables, pipes, and electrical lines. When planning the site improvements, consider the following: • The home location should be level. • Avoid contact with large trees, steep slopes, poorly drained areas, and poten- tial flood zones. • Preserve trees and shrubs for shade, visual screens, and windbreaks. • Plan the driveway, parking areas, septic, well, other structures, and utility lines. v , i. VZZ Site Preparation. The home manufacturer has no con- trol over the site planning and installation of the home unless the manufacturer is responsible for the home's installation. Final responsi- bility for site preparation, including soil stability and frost heave control, lies with the installer. An improperly prepared site may result in the denial of a foundation - related warranty claim. �Z Fire separation.

STEP 3. CLEAR AND GRADE THE SITE Trim overhanging foliage considering'future growth, potential storms, swaying ;in wind and snow/ice-weighted branches. Remove organic material such, as vegetation, wood, roots, twigs, dead branches, grass, and brush from directly under the home.,Re'move any debris that could become termite infested from the site and surrounding area. Re- move all other debris from the home location, including roots from beneath footing loca- tions. Properly dispose of all items. Crown the site (Figure 4) away from the foundation for the first ten feet with a minimum slope of 1/2 inch per foot. Where property lines, walls, slopes, or other physical condi- tions prohibit this slope, provide the site with drains, swales, or grading to drain water away from the structure. Any fill required to grade the site should be inorganic "con- trolled fi_II" applied in a maximum of four inch layers, compacted between each layer to at least 90% of its maximum relative density. Direct runoff away from the site using ditches and berms (Figure 5). If the home will have skirting, start grading from two feet in from the edge of the home. `/ r� L� H se y y y Arrows Indicate direction of water flow. Grade the ground so that water under porches, decks, and recessed entries flows away from the home. If proper grading is not possible, use other methods such as a drain tile and automatic sump pump system to remove any water that may collect un- der the home. The home is suitable for the installation of gutters and downspouts. When gutters and downspouts are installed, direct runoff away from the home. aun MR 1/15/09 Site, drainage. Moisture un- der the home can result in structural damage to the floor system and other parts of the home.

Inadequate soil bearing capacity or a support sys- tem mismatched to the soil characteristics can result in excessive or differential settlement of the home, which can cause the home to go out of level, resulting in jammed doors and win- dows, cracks in finishes and ruptured plumbing connections. — ^ Skyline Corporation (4-48 PG. 1) 119.2009 9:22 AM STEP 4. DETERMINE SOIL CONDITIONS Examine the soil type under the proposed home location to make sure it is suitable for placement of a home. The design of the home's support system, including footing/pier spacing and size, will in part be determined by the bearing capacity of the soil, and 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 excavated) 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. 14 • The water table must be below the lowest level of the planned support sys- tem/foundation. A soil's bearing capacity can be greatly reduced when it is saturated with water. Note that water tables may vary with seasonal or cli- mactic conditions. Consult a geologist or the LAHJ if you are unsure of the water table level. • The soil must not be a highly expansive type. Expansive soils can expand when they become saturated with water, causing the home to shift and be- come unlevel. If soils are expansive, contact a registered engineer, or regis- tered architect to assist with the design of the foundation system. STEP 5. DETERMINE SOIL -BEARING CAPACITY AND FROST LINE The soil under a home must be capable of withstanding the loads imposed by the weight of the home, its support system and furnishings, as well as any loads imposed by wind, snow, or other climactic conditions. SOIL -BEARING CAPACITY Determine the soil -bearing capacity in pounds per square foot (psf) before designing a support system. The higher the capacity (psf), the more weight the soil can hold without unduly compressing. As the soil -bearing capacity increases, footings can be reduced in size or spaced farther apart. Use one or more of the following methods to determine the site's soil bearing capacity: • Test the soil. Hire a registered geologist, registered engineer, or registered architect to determine the soil classification and maximum allowable soil bear- ing capacity by testing the soil in accordance with generally accepted engi- neering practice. • Obtain soil records. The local office of the U.S. Department of Agriculture's Natural Resources Conservation Service (www.soils.usda.gov) and/or the LAHJ may have test results and/or soil analyses on file for the area. • Conduct a pocket penetrometer test. Use a pocket penetrometer to esti- mate allowable soil -bearing capacity as follows: 1. Select a location that will be under a footing. 2. Clear an area of a minimum of one square foot at least four inches deep or to the depth of the bottom of the planned footing. 3. Using the instructions provided with the pocket penetrometer, take at least five readings. 4. Discard the high and low readings and average the remaining readings. Round this result down to the nearest soil -bearing value shown in the right column of Table 4. 5. Confirm that the rounded result matches the soil description on Table 4. • Determine soil -bearing value by visual examination. If one of the options above is not available, the values on Table 4 can be used to establish soil - bearing capacity by visual examination. This method provides lower capacity values than the options above. Accurate soil identification typically requires special training or expertise. An engineer or building code official may be able to assist in classifying the soil found on the site. PFs #Q, iq; conf• to aun MHcss 1115/09 V 1? �_Zd Soil bearing capacity. Sup- port systems on soils with bearing capacities less than 1,000 psf must be designed by a registered engineer or registered architect and approved by the LAHJ. Limitations of pocket pene- trometers. Pocket pene- trometers do not work on sand or gravel. Use Table 4 to determine allowable pressure for these types of soils. If you encounter a layer of gravel, test the soil under the gravel. Do not put the penetrometer on stones larger than its tip as this will provide an inaccu- rate reading. 009 9:22 AN!

Note that soil types may vary across a home site. In this case, the soil with the lowest bearing capacity should be assumed when designing the support system. Keep a re- cord of the soil -bearing capacity value; it will be used later to design the home's sup- port system. FROST LINE In climates subject to ground. freezing, consult the LAHJ, a registered engineer, or reg- istered architect to determine the depth of the frost line.

DESIGN POINT LOAD SUPPORTS All homes will need supports, and therefore footings, under the frame, marriage line (for multi -section homes), exterior wall openings and other heavy point loads. The home manufacturer may have provided a blocking diagram (or tags, labels, paint or other markings under the home) indicating the required locations and/or loads for perimeter, marriage line and/or frame supports specifically for this home. If so, the dia- gram or tags take precedence over the directions provided in this manual. Create a sketch of the home that includes the exterior walls, the frame I -beams and the marriage line(s), if a multi -section home. The sketch will be used in this chapter to lo- cate each support, and note the size of the corresponding footing. Figure 7 is an ex- ample of such a support plan.

A load -bearing perimeter wall foundation system uses a wall along the outer edge of the home to support the home's outside walls. This perimeter support works with interior supports such as piers, columns, and cross beams that support the home's frame and, if multi -section, marriage line. ® STEP 1.

OBTAIN A FOUNDATION DESIGN If a load -bearing perimeter wall foundation design has not been provided by the home manufacturer, it is the responsibility of the retailer and/or home owner to provide a de- sign approved by an engineer or architect, licensed in the state where the home will be installed. The approved design must comply with the LAHJ regulations for foundation design, waterproofing, and drainage, and the following: • The foundation perimeter bearing wall must be supported with a concrete slab or continuous strip footing around the perimeter of the home. Interior piers must be supported by a slab or footings. If footings are used under interior piers, they may be designed as in Prepare Footings, p. 18. • Slabs must extend to the edges of the home. • Footings and slabs must be protected from the effects of frost heave by ex- tending the footings to or below the frost line or by using a frost protected shallow foundation design. STEP 2. EXCAVATE Earate for the foundation, ¢.op y disposing of the earth that is not needed for or site -grading purposes. STEP 3. CONSTRUCT THE FOOTINGS OR SLAB Cm-tstruct the foundation according to the approved design, including the perimeter foundation wall, drainage system, footing(s), and/or slab. STEP 4. CONSTRUCT THE PERIMETER WALL Unless the approved design requires otherwise, construct the perimeter wall with mor- tared and reinforced concrete blocks or reinforced poured-in-piace concrete. Install re- inforcement according to the approved design or LAHJ. Install ventilation and access openings according to the approved design, or if not specified, according to the re- quirements in Complete Under the Home, STEP 3 INSTALL SKIRTING (p. 97). When constructing pockets for an H-beam system, measure the beam depth and lo- cate the pockets carefully. It is critical that when the home's frame rests on top of the H-beam, the perimeter of the floor rests squarely on the foundation wall sill plate Using engineered designs. This section is NOT in- tended to provide a com- plete design for a buildable foundation. A complete design must be obtained that is suitable for the local area and sealed by a pro- fessional engineer or regis- tered architect, licensed in the state. Foundation ready home. Make sure that homes to be installed on a basement or a crawlspace have been ordered with a recessed frame or as foundation - ready, where the frame is designed to avoid interfer- ence with the foundation wall.

STEP 1. PREPARE FOR SET Before beginning the home set, complete the following: • Confirm that the site is property cleared and graded (see Prepare the Site, p. 13_ • Eirsuae that the footings are in place and properly located. Install any utilities that will be difficult to install (e.g. those below grade be- neath the home) after the home is in place. • Secure or remove from the home and properly store all ship loose items (refer to shipping documents for items shipped with the home). • Inspect the home interior, exterior and all provided materials, appliances, and equipment. Immediately report any damage or shortages to the manufacturer. • . The ground moisture retarder may be installed now or after the home is com- plete. See Complete Exterior Work, STEP 2. INSTALL GROUND MOIS- TURE RETARDER (p. 96) for requirement and then return here. For perimeter bearing wall foundations: • Check that the length and width of the home match with the foundation walls. • Check that the two main diagonal measurements of the foundation are equal. • Check that the foundation walls and other support points are within 1/4 inch of level overall and within 1/8 inch of level within any four foot distance. • For naiti-section homes, check that each pair of diagonal measurements for eat portion of the foundation corresponding to a home section are equal. car w4Lf-section homes, find the electrical bonding lugs on the front or rear x rs_ Reverse them to the inside of the outrigger using star washers so w4l be accessible after the home is placed on the foundation walls. • tf L--;irg an H-beam system, remove the frame's shackle hanger if it will inter- paper placement of the beam. STEP CP 2. POSITION HOME SECTION Posi'mn the home section in its final location (if possible, move the heaviest section of the home into place first). Then place materials needed to construct support piers near flheir final locations under the home as determined in Prepare Footings, (p. 18). STEP 3. LIFT HOME Thy are three primary methods available to place the home on the foundation: jack- ir g roffu g and awning_ Jacks, often with roller systems, are typically used for pier and . d "r ems, roller systems are commonly used for crawlspace foundations with load -bed perimeter walls; and cranes are most commonly used for basement foun- dations. Clearances under the home. After the home is leveled, the resulting dis- tance between the bottom of the entire chassis main frame beam and the ground must be no less than 12 inches. Utilize proper cribbing. Manufactured homes weigh several tons. No one should be under the home (whether it is mov- ing or stationary) unless proper cribbing is in place (Figure 17). Failure to util- ize proper cribbing may result in serious injury or death. Leveling during jacking. Keep the home's floor as level as possible during jacking. Twisting or warping the floor can dam- age the structure and finish- ing. Use as many jacks as necessary to keep the floor flat and level.

CRANES When using a crane, follow these guidelines: • Position the home sections) and crane (taking the boom reach into consid- eration) such that they do not have to be repositioned during the set. • Use enough property 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 oorrpression forces on the eaves and to reduce any tendency to slip. • Conned a rope to at least one point on the home so it can be controlled while ak)tL- • 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. Fora 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.

POSITION ADDITIONAL HOME SECTIONS Follow this procedure to install additional home sections: 1. Remove obstructions. Remove protruding nails and staples or anything else that will keep the home sections from fitting together snugly. If present, cut the temporary ceiling and floor plates at the edges of marriage line openings tak- ing care not to damage ceiling or floor coverings or displace temporary mar- riage line support posts (these supports and the plates will be removed after the home sections have been structurally connected). 2. Complete crossovers. Before moving the two sections together, complete any crossover connections that require access from the open marriage line, including the attic duct connection (if present) and marriage wall interior elec- trical connections (see Connect Crossovers, p.52). 3. Position section. Position the section as closely as possible (ideally within six inches) and line up with the previously set section.

Pori an antifreeze solution into all drain traps, including sinks, tubs, and toilets- Be sure that the antifreeze is safe for the fixtures and P- traps. STEP 3. CONNECT GAS SERVICE CONNECTION If the home uses natural or kpid petroleum gas (LPG, also known as propane) for water or space heating, cooking or other appliances, follow the procedure described below: 1. Inspect vents. Assure that all exhaust vents on gas -fired equipment are se- curely connected and that roof jades and stacks have not come loose during transit and they are properly installed. 2. Review appliance instructions. Review each appliance manufacturer's in- structions before the home is connected to the gas supply. Most gas appliances are typically configured to operate on natural gas. If the gas supply will be LPG, consult the appliance manufacturer's instructions to determine what changes need to be made. For homes located above 3,000 feet, appliances may require a different orifice. 3. Remove cap. Remove the protective cap from home inlet pipe and install a full flow shut-off valve at the supply inlet Figure 96). 4. Install regulator- The gas piping system is designed for a pressure that is at least seven inches of water column (4 oz_ per sq in or 0.25 psi) but not more than 14 inches of water column (8 oz. per sq in or 0.5 psi). If gas from any sup- ply source exceeds, or could exceed this pressure, install a regulator if required by the LAHJ. 5. Connect supply. Using matching threaded fittings, connect the gas supply to the inlet side of the shut-off valve. 6. Close valves. Close all valves at appliances prior to opening the main supply valve.

TESTING After testing the electr� system and connecting the water lines check the water system for leaks using one of the procedures described below. Before testing, close all water faucets, spigots, and todet-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 together. This will protect the hot water tank from damage and protect those involved 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 loca- tion shown in Figure 84. Pressurize the system with water at 100 psi, and then isolate it from the pressure source. Bleed all air from the highest and farthest points in the system. 4. Hold presses 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 c5scarding bad pipe sections or joints and installing new pipe or joints with coupik-igs_ 6. Repeat. Repeat the test until all leaks have been eliminated. Pneumatic: 1. Bypass water heater.

Skyline Corporation (4-48 PG. 1) V9/2009 9:22 AM SIDEWALL VERTICAL ANCHORS Homes designed for Wind Zones II and III also require vertical tie -downs along the side- walls. The vertical tie -down anchor straps (or brackets for connecting to the home) are factory installed and indicate the locations. Vertical and frame side wall tie -downs may connect to one double -headed anchor or each to its own dedicated anchor. Any factory -installed sidewall tie -down straps must be connected to a ground anchor re- gardless of the wind zone in which the home is placed. END WALL FRAME ANCHORS End wa11 frame tie -downs are especially important for homes that are wider, and have higher roof pitches because those features increase the surface area exposed to wind loads at the ends of the home.

Configure skirting. Run the skirting along fhe perimeter of the home's heated, conditioned space. Do not enclose with skirting areas under recessed entries, porches, or decks (whether constructed as part of the home or added on site) unless skirting is of the fully vented type and installed so as to allow water to freely flow out from under the home. 2. Fasten 'skirting. Recess the skirting under the siding or trim and attach it to the home in a manner that prevents water from being trapped between the siding or trim and the skirting. For wood, aluminum, or fiberglass skirting, in- stall a skirt rail (lumber strip) under the floor inset at least 1-1/2 inches from the edge of the siding for attachment of the skirting. Allow for frost heave when installing skirting in areas subject to frost. 3. Provide ventilation. Unless the skirting has integral ventilation openings that meet the following ventilation requirements, install equally sized ventilation openings on at least two opposite sides of the foundation. Size ventilation area to equal at least one square foot or each 150 square feet of under -floor area (or for each 1,500 square feet if a ground moisture retarder is installed according to STEP 2.
