THIS MANUAL HAS BEEN WRITTEN FOR THE SAFETY AND BENEFIT OF PROFESSIONAL CONTRACTORS, TRAINED IN THE SETUP AND INSTALLATION -OF- MANUFACTURED- HOMES: IT IS -NOT- INTENDED- TO ENABLE SOMEONE UNFAMILIAR WITH MANUFACTURED HOME SETUP TO PERFORM THE INSTALLATION. IF YOU HAVE NOT BEEN TRAINED IN SUCH SKILLS, ATTEMPTS TO REPAIR OR PERFORM SETUP FUNCTIONS SUCH AS BLOCKING, LEVELING, UTILITY CONNECTIONS, CLOSE-UP, ETC., COULD RESULT IN DAMAGE TO YOUR HOME OR INJURY TO YOURSELF OR OTHER PERSONS. Most states have specific licensing requirements for manufactured home installation contractors. Section V in your Homeowner's Manual lists State Administrative Agencies (SAA) that may be contacted for this information. If your state is not listed, you may contact the Department of Housing and Urban Development (HUD) in the city or nearby city in which you live and they can provide you with those requirements. Palm Harbor Homes requires that only experienced, qualified manufactured home installation specialists perform the installation of your new home. Your Retailer either has such people in his employ or will be able to contract the work with reputable, independent, local professionals. We encourage you to read these instructions to familiarize yourself with the installation procedure and recognize the importance of proper installation, especially the sections on "Site Preparation" and "Skirting", typically Homeowner responsibilities. Vital information regarding the design criteria of your home will be found on called a Data Plate, located inside the home. The Data Plate is your reference guide about the functioning of your home within the geographical area for which it has been designed. The Data Plate is typically located on a kitchen cabinet door or on a wall panel or door face near the electrical panel, utility room or bedroom closet. Most of the installation requirements are determined from the information contained on this certificate. Please review the information on the "Data Plate" with the Design Zone maps below, to ensure your home meets the design criteria for the geographical area of the site location. CAUTION: When site is located in coastal areas of either Wind Zone 2 or 3, and within 1500 ft of the coastline, the "DATA PLATE" should indicate compliance with "EXPOSURE D". Damages caused by or resulting from the installation process and/or settling are not covered by your new home warranty. Section 1, Before you begin Page 1 COPYRIGHT © 2000 BY PALM HARBOR HOMES, INC.

SECTION 1 - BEFORE YOU BEGIN SECTION 11- MISCELLANEOUS AND FINAL INSPECTIONS AWNING, CARPORTS, PORCHES, UTILITY ROOMS, ETC. Additional structures such as awnings carports, patio covers or attachments to a Palm Harbor home have not been taken into consideration nor calculated into the design for roof or wind loads. Any additions made to the home must be self-supporting and shall not interfere with exterior weatherproofing (i.e. shingles, flashing, gutters, siding). CLEARANCES If there are any low -hanging trees or bushes adjacent to your home, which could damage the exterior or the roof of the home, they should be trimmed or cut accordingly. Future growth of these bushes or trees should be considered in connection with their possible movement during wind conditions or under snow or ice loads. FINAL-INSPECTION Afterthe home has been completely set up, a final inspection should be made to ensure that no items have been overlooked which could cause a service problem. For your convenience, a typical "Final Inspection Check List" has been provided at the end of this section. Palm Harbor recommends that after approximately 60 days, recheck pier supports for settling and readjust as needed. Annual releveling may be required. CONSEQUENCES OF INCORRECT SETUP INCORRECT SITE PREPARATION, BLOCKING, LEVELING AND CONNECTION OF THE SECTIONS OR UTILITIES, COULD RESULT IN ONE OR MORE OF THE FOLLOWING: • Loosening of trim pieces, molding, walls, wall panels and ceiling panels. • Cracks in drywall ceiling and wall panels. • Excessive deflections in floor, ceiling and roof. • Poor waste line drainage due to reverse slope. • Damage to chassis and transportation system. • Buckling, bowing or loosening of exterior siding, trim, soffits, etc. • Cold spots due to voids in insulation.

All Rights Reserved. SECTION 1 — BEFORE YOU BEGIN The procedures outlined in this manual are intended to provide requirements for proper installation in compliance with the Federal Manufactured Home Construction and Safety Act of 1994 for manufactured homes. Terms used in this manual are those as defined in NCSBCS A225.1, Manufactured Home Installations, which is hereby incorporated by reference. In case of discrepancies, the Palm Harbor Manual shall prevail. This manual shall not be construed as relieving the installer of responsibility for compliance with State and/or local ordinances, codes and regulations established by the authorities having jurisdiction. Site preparation is the fundamental key to a successful installation and is typically a Homeowner responsibility. The major considerations are soil stability, moisture control and utility locations. FROST HEAVE: Special consideration must be given in cold climate areas where frost heave can be a problem. Frost heave can occur when moisture in the soil freezes below the footing, causing the piers that support the home to rise and result in serious damage to the home. Controlling the amount of moisture in the soil can reduce risk of frost heave. Soil type, grading and drainage, ground vapor retarder, skirting, crawlspace ventilation, heat loss through the floor and the apparent water table depth can all affect the amount of moisture available that can freeze. Local building officials or the authority having jurisdiction may require footings to be placed or poured below the frost line. If footings are not placed or poured on firm, undisturbed soil or compacted fill below the frost line, frequent pier and anchoring device adjustment may be required during the year. SOIL CONSIDERATION: Before a builder begins construction on a housing development or building, he will obtain Section 1, Before you begin Page 4 test data from soil analysis reports so he will know if his foundation design will support the structure(s) and sustain, within allowable stress and settlement limitations, all applicable design loads. The bearing capacity for the soil at your home site must be known to determine the correct relationship between footing size and pier spacing. A common method for determining the bearing capacity of soil relies on selecting values from tables of allowable or presumptive bearing capacities given in local building codes. Such tables are commonly obtained from the local authority having jurisdiction or local geographical surveys, however, the exact "type" of soil must be known. In general, the local office of the Soil Conservation Service (SCS) will have information available at no cost. You may also use a "pocket penetrometer", such as model 424-050, available through: SOILTEST Northwest Business Center 2260 Northwest Parkway Marietta, Georgia 30067 (404)980-0913/14 or1-800-356-4662 The minimum basis for the pier spacing tables contained in this installation manual is 1000 pounds per square foot (PSF).

SECTION 10 — SHIRTING AND VENTILATION VENTILATION REQUIREMENTS: ACCESS: An access door, allowing In addition to the vapor retarder, admittance to the underside of the home, ventilation of the crawlspace area under should be provided for maintenance and the home may also be required. To repair. When installed, the door should ensure adequate cross ventilation, measure at least four (4) square feet and provide ventilation openings in the have a least dimension of not smaller enclosure on all sides and at least one than 18 inches. If this door is screened, ventilation opening at each corner of the it may qualify in the ventilation enclosure. When site installed amenities, requirement but ensure that the door has such as a raised poured concrete floor louvers or some other provision for for deck or porch, prohibit installation of keeping rain from entering the enclosed vent openings, these vents should be underside of the home. Local relocated elsewhere along that side, or, jurisdictions may have additional the vent net free area of the vents to requirements. either side of the obstruction adjusted accordingly. APPLIANCE EXHAUSTS & Use vents that have provisions for DRAINS: The clothes dryer exhaust keeping rain from entering the enclosed vent MUST NOT BE ALLOWED to underside of the home. Louvered vents terminate underneath the home. Federal or vents with a hood or a shroud will Standards require the vent to be perform this function. exhausted outside the perimeter 1. The maximum distance between vents as shown above, is based on 80 square inches of "NET FREE" area for each vent. Do not use overall dimensions of vent for determining the net free area. Insect screens on the ventilation openings can restrict free air area as much as 50%. For vents with less than 80 square inches of net free area, reduce the distance between the vents accordingly. Example: selected vent has 40 square inches of net free area, then the adjusted distance between vents is: 40in2/80in2 x 25ft = 12.5 or 12'-6" 2. When ventilated skirting is used (i.e.: skirting with precut holes or slots) make sure the total accumulated free area provides at least one square foot of vent area for every 150 sgft of floor area (excluding porches/recessed entries). Section 10, Skirting & Ventilation Page 2 enclosure. Hot water heater temperature and pressure relief valve overflow drains and air conditioning condensate lines must also terminate outside the perimeter enclosure. Read the instructions on the installation of all appliances, including wood burning fireplaces and fuel burning sealed combustion water heaters and furnaces (if applicable) prior to the installation of perimeter skirting for the proper venting, access and/or draining of those appliances.

SECTION 1 - BEFORE YOU BEGIN SECTION 10 - SKIRTING AND VENTILATION B) Typical single- or multi -section The installation of perimeter skirting between the home and the ground not only enhances the appearance of the home -but -also -may -substantially- reduce heat loss through the floor. Provisions must be made, however, to allow for the dissipation of moisture which would otherwise enter the home. Damage caused by moisture due to improper grading and/or insufficient ventilation to the underside of the home is not covered by the Palm Harbor Homes New Home Warranty. GROUND VAPOR RETARDER: As stated previously under "Site Preparation" in Section-1, the ground surface under the home must be covered with 4 mil, or thicker, polyethylene or equivalent material, that resists ground moisture. The plastic cover must be overlapped at least 12" at all joints, and weighted down, so that it does not blow loose. See also the following details. A) Typical single- or multi -section with recessed entry ngol Section 10, Skirting & Ventilation Page 1 with open deck or covered porch/screen room. s Notes: 1. Unless footers/piers are required to be installed below grade (i.e.: frost line) the vapor retarder may be installed before setting piers. 2. Areas under recessed entries, open E2 porches or screened porches should be separated from the area underneath the main unit(s) by installing min. 4 mil. vapor retarder as shown, or, by skirting or foundation walls following the exterior walls of the main unit(s). In either case, the vapor retarder is not required under the recessed entry or porch areas. COPYRIGHT © 2000 BY PALM HARBOR HOMES, INC. All Rights Reserved. capacities less than 1000 PSF must be designed by a registered Professional Engineer or Architect and approved by the local authority having jurisdiction. - - Because Palm Harbor Homes has no control over the site planning and installation of your home, final responsibility of the site preparation, including soil stability and frost heave control lies with you, the Homeowner. Settling due to inadequate soil conditions and/or improper installation is also beyond our control and we strongly recommend that the pier supports be inspected frequently for settling and readjusted as needed. Decreased pier spacing may be required or larger footings may be necessary. Annual releveling even under ideal conditions may also become necessary. GRADING AND DRAINAGE: The ground directly below the home should be clean and free from tall grass. The area under all footings must be cleared of all organic material, such as grass and matted vegetation. The grade around and underneath the home MUST he sloped so that water will not accumulate or stand under the home. If water is allowed to flow beneath the home (even if it does not accumulate), erosion of the soil at the pier footings can occur and affect pier stability. Pier movement and resulting settlement can cause serious damage to the home. GROUND VAPOR RETARDER: Moisture can enter the home from the soil beneath it and cause damage to the floor structure, exterior walls and other building components. Section 1, Before you begin Page 5 The ground surface under your home must be covered with 4 mil (or thicker) polyethylene or equivalent material to resist ground water vapor when the -crawlspace—is--enclosed - -or skirted. Overlap the plastic cover at least 12" at all joints, and weigh it down with blocks, bricks or rocks so that it does not blow loose. See Section 10 for specific instructions and more details. GROUND LEVEL INSTALLATION ... Floor at grade Ground level installation refers to the installation of the home over an open, excavated area where the supporting piers and foundations are below finished ground level. This type of installation is not recommended in geographical locations where ground moisture is a problem. Provisions for drainage and ventilation must be made to allow for the dissipation of moisture in the excavated area, which would otherwise enter the home. Damage caused by moisture due to improper grading and/or insufficient ventilation to the underside of the home is not covered under the Palm Harbor Homes New Home Warranty. COPYRIGHT © 2000 BY PALM HARBOR HOMES, INC. All Rights Reserved. SECTION 1 — BEFORE YOU BEGIN PERMANENT FOUNDATION INSTALLATION If the home is to be placed on a permanent foundation (either over a basement or crawlspace), the foundation construction, including all provisions for utility connections should be made prior to the delivery of the home to the home site. Refer to the Detail below for a typical permanent foundation design. The detail shown is an example only. Specific site conditions will determine final foundation design. A registered professional engineer must design foundations. The manufacturing facility of your home may have some approved designs available. Check with your retailer on availability. Only competent, qualified professionals, experienced in this type of home installation should attempt to move sections over basement or crawlspace areas using commercially available mechanical equipment designed for this type of work. These devices are comprised of adjustable transfer beams that span the full basement with jack stands to support the transfer beams from the basement floor, and cradles that hold the home's I -beams. When properly operated, they allow safe, easy movement sideways, forward and backward, utilizing roller bearings with hand winches. If your home was constructed with provisions for a stairwell opening, the floor framing must be removed at that location. (Refer to the appropriate addendum accompanying this installation manual for more details.) Upon relocation of the home from its initial installation, such framing must be reinstalled.

Oil supply tanks affixed to the home shall be located as to require filling and draining from the outside and shall be in a place readily available for inspection. If the fuel supply tank is located in a compartment of the home, the compartment shall be ventilated at the bottom to permit diffusion of vapors and shall be insulated from the structural members of the body. Tanks so installed shall be provided with an outside fill and vent pip and an approved liquid level gauge. A readily accessible approved manual shut-off valve shall be installed at the outlet of oil supply tank. The valve shall be installed to close against the supply. All oil tanks, except for integrally mounted tanks, shall be equipped with an approved oil filter or strainer located downstream from the tank shut-off valve. The fuel oil filter or strainer shall contain a sump with a drain for the entrapment of water. Air Conditioning Equipment: When it comes to the size of your air conditioner or heat pump, bigger is not better. Air conditioners and heat pumps should be sized to meet the cooling needs of your home. Equipment that is too large will turn on and off frequently allowing moisture to build up in your home. The equipment will also cost more than properly sized products and result in higher energy costs. Section 9, Utility Connections & Tests, Page 7 COPYRIGHT © 2000 BY PALM HARBOR HOMES, INC. All Rights Reserved. SECTION 9 - UTILITY CONNECTIONS AND TESTS If there is a gas crossover, connect it per the applicable methods shown below. The gas piping system has been tested at the factory, however, before -the system is connected, the piping should be tested to ensure no leakage. Before turning on the gas, make certain METHOD A: FACTORY INSTALLED. MALECAP FEMALEFITTING. INSTALLED ON FEMALE CAP -i INLET SIDE. „ DIRECTION OF GAS FLOW CROSSOVER MUST BE LISTED FOR EXTERIOR USE. METHOD B: INSTALLED ON FLEX CONNECTOR INLETSIDE. FACTORY INSTALLED. MALE CAP OR � DIRECTION OF GAS FLOW CROSSOVER MUST BE LISTED FOR EXTERIOR USE. all gas connections have been made tight, all appliance valves turned off, and all unused or unconnected outlets are capped. After turning on the gas, test the gas piping and the connections to appliances for leakage with soapy water or bubble solution. Light all pilots and test appliance operation. In some localities, utility companies and/or building inspectors may require additional tests as follows: NOTE: Before a test -is begun, the temperature of the ambient air and of the piping should be approximately the same. Conduct the test(s) at such a time during the day when air temperatures will remain constant. 1.) Isolate all appliances with appliance shut-off valves. Pressure shall be measured with a mercury manometer or slope gauge graduated in increments of not greater than 1/10 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" (but not more than 14") water column and applying a bubble solution to all joints. WARNING DO NOT pressurize the system in excess of the pressures stated above. OIL CONNECTION For an oil -fired furnace, the installer must use only approved materials from the supply to the furnace connection. After the supply line is connected, check for leakage. Where penetration has been made through the bottom of the home, make sure all holes in the bottom board are sealed tight and made rodent -proof. Oil tanks and listed automatic pumps (oil lifters) installed for gravity flow of oil to SECTION 2 - FOOTERS AND PIERS WARNING! EACH SECTION (SINGLE OR MULTI WIDE) WEIGHS SEVERAL THOUSAND POUNDS! ADEQUATE BLOCKING MUST BE USED TO SAFEGUARD ALL PERSONNEL AND THE STRUCTURE DURING ALL PHASES OF INSTALLATION. WORKERS MUST NOT BE PERMITTED TO WORK UNDER THE HOME WHERE THEY MAY BECOME INJURED SHOULD THE HOME SLIP DURING THE INSTALLATION PROCESS. The tables included in this manual assume each section acts independently, regardless of whether the home being installed is a single-, double- or triple section. Select the appropriate width for the section being installed and space piers according to the individual section width. FOUNDATION DESIGN: The procedure described below and on the following pages represents a typical concrete block pier system utilizing precast concrete 8" x 16" x 4" OR 16" x 16" x 4" footing pads and 8" x 8" x 16" concrete blocks, common sizes used in the manufactured housing industry. This procedure offers MINIMUM installation requirements for the setup of Palm Harbor homes. Larger footings including poured concrete footings or runners may also be used. Multiple pads used in combination to achieve the required footing area may be used. OTHER APPROVED DESIGNS: Other foundation systems may also be acceptable provided the system has been designed by a registered professional engineer, approved for the use intended by local authority having jurisdiction, and installed in accordance with those approved plans and specifications; however, all applicable provisions of this Palm Harbor Homes Installation Manual shall apply. Approved plans, specifically designed for your home may be available from the home manufacturer. Please contact your retailer for availability. MANUFACTURED PIERS: Manufactured piers may also be used provided they are listed and labeled by an authorized approval agency and the piers are installed in accordance with their listing. If steel piers are used, steel channels or angles at least 6" long must be used to distribute the load to prevent web crippling. Manufactured piers and channels or angles must be certified to have a load capacity greater than or equal to the load it is to carry. Steel piers, channels or angles that are not constructed from material with corrosive resistive properties shall be made so by painting. FOOTINGS: The area under all footings must be cleared of all organic material such as grass and matted vegetation. All footings are required to be placed or poured on firm, undisturbed soil or compacted fill. Section 9, Utility Connections & Tests, Page 6 COPYRIGHT © 2000 BY PALM HARBOR HOMES, INC.

All Rights Reserved. All Rights Reserved. SECTION 2 - FOOTERS AND PIERS MAXIMUM PIER HEIGHT: The maximum allowable height for piers is indicated in the pier details above. However, for Wind Zone H and III installations, additional limitations to the pier height may be necessary, depending on the vertical tie down spacing and/or the attachment of the diagonal straps at the I-beam. See Section 7, Anchoring, for more details. CLEARANCES: An "average" minimum ground clearance of 18" must be maintained beneath the underside of the floor joists and 12" beneath the main I -Beam chassis. More clearance may be required for heat duct crossover. A minimum ground clearance of 8" must be maintained to all exterior siding materials. HERS V ER 12- MGH "Average" means at least 75% of the piers are at the minimum height. Conversely, the maximum pier height may be exceeded without the need to increase the pier design, when at least 75% of the piers are at the maximum height or less, and the remainder of the piers do not exceed the maximum height by more than 8 (eight) inches, except that single stacked piers shall not exceed 36 inches in height. SECTION 9 - UTILITY CONNECTIONS AND TESTS Connect the crossover wires in the junction box as follows: 1. The wires to be connected are either color coded, numbered, or of two different sizes. Separate the wires into the proper combination. 2. Strip the wires of each combination and connect the wires per color code (white to white, black to black, ground to ground) with the appropriate size wire nuts. 3. Make sure that the box and/or cover plate(s), if metal, are grounded by the use of the ground wire. Secure junction box cover(s) with machine screws, not sheet metal screws. Electrical bonding is also required between units per the following detail: STEEL OUTRIGGER OR HEADER NEAR MARRIAGE LINE MARRIAGE LINE It SOLDERLESS LUG BARE COPPER WIRE COILED UP AT FACTORY.

All Rights Reserved. SECTION 3 - BLOCKING AND LEVELING PROCEDURE GENERAL NOTES AND TABLES STEP 1. Confirm the home is structurally designed for the geographical area for which the home is to be installed by examining the structural design maps shown on the Data Plate located inside the home. Use the "Design Roof Load Zone Map" and the "Design Wind Zone Map" shown in SECTION 1 to determine the zone (South, Middle or North) where the home is to be installed. Use Table 1 for the Roof Load Zone to determine if perimeter blocking is required. Some homes, constructed with an optional structural package, may not require perimeter blocking and will be indicated as such on the Data Plate. Where greater roof live loads (snow loads) have been determined to exist in localized areas by the authority having jurisdiction through surveys or experience, such roof live loads shall apply and perimeter blocking may be required. See pier plan and/or DATA plate for design load of the home. Likewise, a home designed for higher roof loads may be installed in a lower roof zone. Example, a home designed for 30 PSF roof live load (obtained from the Data Plate) may be installed in the South Zone requiring only 20 PSF roof live load. The rows designated "South" in Table 1 may then be used to determine pier spacing and if perimeter blocking is required. STEP 2. If it was determined in Step 1 that perimeter blocking IS NOT required for the installation, use Table 1. Locate the rows that correspond to the zone for which the home is to be installed (South, Middle or North). Select the row with the soil bearing equal to or lower then the bearing capacity established earlier. If it was determined in Step 1 that perimeter blocking IS required for the installation, use Table 2, locate the rows that correspond to the zone for which the home is to be installed (South, Middle or North). Select the row with the soil bearing equal to or lower then the bearing capacity established earlier. STEP 3. Using Table 1 or Table 2 determined in Step 2, locate the column(s) that correspond to the width of each section and the footer size selected. STEP 4. At the intersection of the columns and rows determined in Steps 2 and 3 ascertain the required pier spacing to be placed at the I -Beams of each section. Spacing of the piers is measured from center to center. STEP 5. Determine the type of pier to be used based on the "AVERAGE' height of the piers installed. Refer to the "Typical Pier Design" Section. "AVERAGE' means piers installed in at least 75% of the overall length of the unit, must not be less than 12 " height (See Section 2 for detail). Note: Table I and Table 2 are based on typical 16xl6x4 footing pads. When other types or size of pads are used, refer to Table 1.1 , for I -Beam piers only, or Table 2.1, for perimeter piers. These tables list minimum pier design loads for various floor widths when spaced 4,6 or 8ft on center. The capacity of the desired pad for the soil conditions present must be equal to or greater than the load listed for the desired spacing. See also example in the Notes for Table 2 and 2.1.

SECTION 9 - UTILITY CONNECTIONS AND TESTS WATER CONNECTIONS The inlet for the waterline is typically located near the hot water heater. The Federal Standards require that this line be equipped with a master cold water full flow shut off valve installed in an accessible location. This valve is not supplied with the home but must be provided by the installer or homeowner. All field installed water piping must be flushed free of all debris prior to connection to the home's water inlet. If there is water service to multiple sections, connect the water supply crossover lines as shown in the applicable detail. METHOD A: �--MARRIAGE LINE I WATER LINES pppROVED FLE%CROSSOVER CONNECTOR(COPPER, POLYBUTYLENE, ETC.). METHOD B: �—MARRIAGE LINE To ensure that hot and cold lines are not cross connected, they have been color coded or tagged. If the water crossover connection is not within the insulated floor envelopes, wrap the exposed water lines in insulation and secure with a good pressure sensitive tape or non-abrasive strap, or enclose the exposed portion with an insulated box. If the local water supply exceeds 80 PSI, a pressure -reducing valve must be installed. Remove all aerators and open all faucets fully when turning on water for the first time and allow the water to run for several minutes. The home has been tested at the factory, however, check for leaks at the inlet, appliances and at the fixtures. DAMAGES CAUSED BY WAT LEAKS THAT COULD HA BEEN DETECTED DURING TI INSPECTION ARE N COVERED BY YOUR PAl 311 HOMES NEW HOMEI W If water piping at the inlet is exposed, a heat tape should be installed to prevent freezing.

Secure light to the outlet box and caulk to ensure watertight seal. Refer- -to the -instructions —mentioned above for the location of combustion air ducts. If applicable, this duct must be extended to the outside of the home. The combustion air inlet shall not allow material from the hearth to drop beneath the home. Typically, these ducts are factory installed, however, all instructions necessary for the installation of the combustion air ductwork are provided in the home, located either inside the fireplace or with the chimney parts shipped with the home. When extension of these ducts is not necessary, make sure to remove any protective coverings installed for shipment (i.e.: tape, caps, etc.), before using the fireplace. OTHER APPLIANCES Other appliances and/or materials may be shipped loose with the home. The installation and operating instructions for those appliances are, provided in the home, usually with the appliances themselves or in a drawer in the kitchen. Run hot water heater temperature and pressure relief valve overflow pipe to the perimeter of the home (through perimeter skirting, if applicable). Do not allow this drains to terminate directly beneath the home. EXTERIOR LIGHT INSTALLATION Some models may be shipped from the factory with lights not installed. If needed, attach mounting plate(s) with machine screws, not sheet metal screws. Attach wires per color code (white to white, black to black, ground to ground) with wire nuts. Make sure that the mounting plate(s), if metal, is (are) WARNING HOMES WITH COMBUST ERIOR SIDING (HARDBO YL, LOG, ETC.), INSURE 7 FLASH RING HAS I PERLY INSTALLED BETVI ELECTRICAL BOX AND ERIOR SIDING INTERIOR TRIM OUT Cut to size and secure the ceiling close-up material.

Install missing row(s) of shingles as required. Secure shingles per the shingle manufacturer's installation instructions (found on the shingle wrapper). EXTERIOR END WALLS, MULTI SECTIONS ONLY Cut closure material to the shape and size required and secure in place starting from the bottom up, i.e. bottom starter, vertical metal or siding, then roof overhang soffit and fascia. All closure material should be fitted and sealed as required to protect the structure or interior from the elements. BOTTOM BOARD REPAIR The bottom board underneath the home has been sealed at the factory; however, the bottom board may subsequently incur tears or punctures during transportation or installation. These holes must be sealed to prevent the entrance of rodents or insects. The bottom board may be repaired by the method listed below: Construct a repair piece to be placed over the tear or puncture utilizing scrap pieces of bottom board material. This material is a special high -strength rodent -resistant covering, and may be purchased from manufactured housing retailers or manufactured home supply outlets in your area. Apply the repair piece over the area to be repaired with contact cement and staple the piece at the perimeter with a flare tacker stapler. Manufactured housing supply outlets typically carry_ special repair kits and special pressure sensitive tapes for bottom board repair that work equally as well. Follow the manufacturer's instructions on the repair kit accordingly. HEAT DUCT CROSSOVER CONNECTION Install the crossover heat duct (min. R-8) as shown in the detail.

Either SECTION 3 — BLOCKING AND LEVELING PROCEDURE GENERAL NOTES AND TABLES Notes for Tables 2 and 2.1 1. Maximum I -Beam pier spacing as shown in Table 2 above for fixed size footing pads, or adjusted to larger area footing pads based on loads in Table 2.1. For either case, the maximum I -Beam pier spacing is-8'=0" for 8" I=beam chassis, 10'-O for 10"-I=Beam and IT-0"for 12"I-Beam-chassis: 2. Perimeter pier spacing as shown in Table 2, or adjusted to larger footing pads per loads in Table 2. 1, but in no case greater than 8'-0". 3. When perimeter piers are required, additional piers must be installed along the mating line of multiple section units where mating walls exist. Piers are not required in open span areas. Where mating walls exist on one section only, the maximum spacing is the same as the perimeter spacing as determined in 1 and 2 above. Where mating walls are directly opposite to each other (one on each section), the maximum spacing is half the perimeter spacing, or as determined for combined loading in table 2.1 above. These piers are in addition to the piers located at open span area columns.(see also Section 4) 4. The distance between any adjacent piers may deviate from the listed spacing by 10%G, so long as the overall average distance between piers is equal to or less than the listed spacing. 5. See footer details in Section 2 for double tooter configurations. 6. For 2x10 min. lumber footers, use pier spacing tabulated in the 16x16x4 column. Refer also to lumber footer configurations and requirements in Section 2 of this manual. 7. All the above requirements must be adhered to when a min. 4" thick slab is installed. For pier spacing on the slab, the double 16xl6x4 column may be used. The slab may count as the bottom layer of required pads as shown in Section 2. Special designs are required for slabs located in areas prone to frost heave. Special designs are also required for `ribbon' footing designs. 8. For 500 PFS soil, size the footing according to the pier load table in Section 4. 9. Example for using Alternate Tables 1.1 and 2.1: alternate pad desired has 1800 LBS bearing capacity in 1000 PSF soil. The home is a 14 wide to be installed in the 20 PSF roof load zone using perimeter blocking. a) In Table 2. 1, find the column for a 14 wide floor. b) Going down the column find a load which is equal to or less than the pad capacity of 1800 LBS. make sure to line up with the appropriate roof load (20 or `South' zone). c) From the table, read maximum spacing for I -Beam piers. Load at 8'-0" pier spacing is 2115Lbs, NO GOOD since pad capacity is 1800 LBS max. Load at 6'-0" is 1585lbs, OK since less than pad capacity. + I -Beam piers may be at max. 6'-0" d) Repeat procedure for perimeter piers. Load at 6'-0" is 2035 LBS > 1800 LBS 4 No Good Load at 4'-0" is 1360 LBS < 1800 LBS + OK FOOTING CAPACITY TABLE (POUNDS) FOOTING SOIL CAPACITY PS SIZE in. 500 1,000 1,500 2.000 1 2.500 3.000 16 x 16 x 4 600 1,490 2,377 3,265 4,154 5,150 16 x 32 x 4 1,490 3 266 4 743 6,289 7,500 8,681 18 x 18 x 4 835 1,960 3,085 4,192 5,317 6442 20 x 20 x 4 1,090 2,490 3,877 5,228 6,617 8,006' 24 x 24 x 6 1 700 3,710 5,710 7,555 9,555 11,329' 30 x 30 x 6 2 835 5,960 9,085 11,706' 14,831' 17,956' Notes: 1. Footers for loads exceeding 10,000LBS, or for the condition indicated by'*', require double stacked block piers (see pier `B' and pier `C'). 2. 16x32x4 footer consists of double stacked 16xl6x4. See tooter details. 3. For double 2x10 min, lumber footings, use the loads tabulated for 18x18x4 footers. 4. These footing loads are also applicable when an equal thickness of slab is installed. 5. Premanufactured footers may alternatively be used within the terms of their approval and max. load capacity.

SECTION 3 - BLOCKING AND LEVELING PROCEDURE GENERAL NOTES AND TABLES Column Loads: the following tables may be used to determine column loads when a load and pier diagram was not provided with the home. Make sure t0 use the Table corresponding with the roof load zone the homeis installed in. NOTE: Column loads are for individual sections. Loads for adjacent columns (one each section, directly across from each other), must be added together. WALLMORE THAN 16in IN WIDTH COLUMN POST OR WALL, LESS THAN 161n IN WIDTH. DOORR PAN °D PAN °C° OPEN'G PAN'B° ---------SPAN 'A' LESS THAN 48° IN WIDTH G COL COL COL Example: A 26 wide consisting of a 12 & 14 wide section is installed in Roof Load Zone SOUTH. Determine total loads for COL A, B, and C. Span "A" = 12 8, Span `B" = 10 ft. COL A: Span "A" to COL B is 12 8. From table below for "SOUTH" zone, the load for the 12 wide is 1050 lbs. and for the 14 wide, 1230 lbs. Total Load for COL A=1050+1230=2280lbs. COL B: Since COL B carries the loads from SPAN "A" and `B", the total span is 22 ft. Checking the table (SOUTH) for a 22 ft span on a 12wide, the load is 2041lbs. The load for the 14 wide section is 2391 lbs., for a combined total load at COL B of 4432 lbs. COL C: Span `B" to COL C is 10 ft. From table below (SOUTH), the load for the 12 wide section is 991 lbs. and 1161 lbs. for the 14 wide section. Total load for COL C=991+1161=2152 lbs. The remainders of the column loads in this example are determined the same way as COL C. DISTANCE X' must be added to the span distance when perimeter blocking is required by design, in addition, add 500 lbs. to each side as well.

For model specific pier locations, perimeter blocking requirements (if applicable), refer to the DATA PLATE and pier plans supplied with the home. 2.) Pier spacing is based on each section's floor width, I-beam spacing and Roof Load Zone and soil bearing capacity. Refer to applicable tables in this manual. 3.) For piers required at sidewall for openings larger than 4'-0", use a minimum 16x16x4 footer or equivalent. 4.) To determine the locations of centerline columns and the associated loads with these locations, refer to the model specific pier- or floor plan, included with this manual. If a specific pier- or floor plan has not been provided, use the column span tables in Section 3. If not already identified on the perimeter joist at the marriage line, mark these locations on the bottom of the interior perimeter joist with a nail or light color chalk or paint, so that they can be easily visible under the home after the sections are put together. Use the FOOTING CAPACITY table in Section 3 to determine the correct footing size for the associated load at the marriage line. EXAMPLE: A 14-wide section without perimeter blocking may, per print, have a 4000 lbs. column load at the marriage line. If the soil capacity at the installation site is 2000 PSF, in the FOOTING CAPACITY table read down the 2000 lbs. column until the footing capacity meets or exceeds the 4000 lb. load. The associated footing size in this example is an 18" x 18" x 4"footing (4192lbs),Ir the soil bearing capacity were 2500 lbs. or higher, a 16" x 16" x 4" footing would be sufficient at the 4000 lbs. column condition.

From the shipping supports, remove any gussets that may be applied over the perimeter joist. Do not remove the support itself. STEP 2. Position the heavier section of the home in the desired location. Carefully bring the lighter section as close as possible to the heavy section. We strongly recommend that the installer use a mechanical roller system specifically engineered for manufactured homes to help facilitate the safe moving of the sections during set up. STEP 3. Use the hitch jack to obtain approximate leveling of the heavy section of the home, placing pier supports under the main I -Beams no more than 24" from the front cross member (measured from the center of the pier to the outside edge of the front cross member). Use a lx6 or 2x6 between the I -Beam and the concrete cap to prevent cracking of the blocks or cap (see pier details). STEP 4. Jack up one side of the heavy section in the axle area with at least one jack in front of the axles and another jack behind the axles. Position the additional jacks along that I -Beam to distribute the load of the home. 1/4" X 1 1/2" X 1/8" MIN. PLATE RND. PIPE (WITH 1/8" MAX. CLEARANCE FOR JACK HEAD) X 1"APPDX. DEPTH. To prevent crippling of the I-beam web and help distribute the load, use steel channels or angles (see example). Carefully operate all jacks simultaneously to prevent excessive stress to the home and raise this side slightly higher than the desired elevation. Place pier supports in front of and behind the axles. If the spacing of these piers exceeded the required spacing indicated in Table 1 or 2, add a pier between the two axle piers. Removal of one or more axles may be necessary to comply with pier spacing requirements. Do not install piers under axles or at spring hanger locations. STEP 5. Repeat STEP 4 on the other I- beam of this section. STEP 6. Place the remaining supports under the main I -Beams maintaining proper spacing and support sizing previously determined. Also, ensure that the centerline of the rear pier supports are located within 24" of the rear of the home (See' typical multi wide pier x- section in the beginning of the section). Section 4, Multi Wide Installation, Page 2 COPYRIGHT cO 2000 BY PALM HARBOR HOMES, INC. All Rights Reserved. SECTION 4 - MULTI WIDE INSTALLATION STEP 7. Level the floor of the heavy section by jacking. The solid concrete cap at the top of each pier should be within 2" of the main I -Beam or perimeter joist. Use combinations of 2", 4" and 8" blocks to achieve this condition. Using a water level, adjust the level of the floor by shimming between the concrete pier cap and the main I -Beams with lx6 and/or 2x6 wood plate(s) and/or wedge-shaped wood shims if necessary. Wood shims must be at least 4" wide and 6" long and cannot exceed 1" in thickness. Shims must be driven tight perpendicular to the I -Beams (see also typical pier details). This shimming method may also be used for perimeter piers. STEP 8. Install the piers required under the center beam columns to support the roof load of the home. These column locations, loads and footings sizes were determined in the beginning of this section. If you identified these locations on the bottom of the interior perimeter joists with paint or chalk as recommended in that step, then place the appropriate piers at the corresponding column locations. Again, the solid concrete cap at the top of each column - supporting pier should be within 2" of the interior perimeter joist. Use combinations of 2", 4" and 8" blocks and concrete caps to achieve this condition. Shim between the concrete cap and the perimeter joist with lx6 and/or 2x6 wood plate(s) and/or wedge-shaped wood shims if necessary. Wood shims must be at least 4" wide and 6" long and cannot exceed 1" in thickness. Shims must be driven tight and perpendicular to the perimeter joist. Total thickness of the combined plates and shims should not exceed 3 1/4 inches.

For ease of anchor installation, locate these brackets now and install anchors directly -below them, or -angled back towards the main beams 30-40 degrees to avoid pier pad(s). Note: Brackets may be installed on either unit. Be sure to check column bracket locations on all sections and install the necessary anchors prior to locating the next section (see also Section 7). - When perimeter blocking is required, install piers along the outer perimeter of the units spaced as required per Table 2 in Section 3 of this manual. Install the piers as shown in the following detail. In addition to the piers along the outer perimeter, piers must also be installed EXTERIOR SIDEWALL - + I I r FLOOR DECKING MAIN I -BEAM �— INTERIOR CROSSMEMBER MAX.

Because they carry the load of two sections, the spacing is half the distance of the —spacing -required- forexterior walls. Perimeter piers are NOT required under open spans along marriage line. For Wind Zone II and III installations, additional piers are required under shearwall ends, where they attach to the sidewalls. Shear walls are indicated on the floor plans as darkened (Filled -in) interior wall sections. See also typical pier diagram on page 1 of this section. STEP 9. To limit air infiltration, a continuous gasket was installed at the factory. Before the sections are joined, carefully check for any voids that may exist in the gasket. It is important to repair these voids BEFORE the units are connected together as those areas may become inaccessible after the sections are joined. Failure to repair will result in excessive air infiltration and possible condensation. To repair or replace missing gasket, use caulking, foam tape or spray or other suitable materials. STEP 10. Using a mechanical roller system, slowly move the floor of the lighter section to meet the heavier section and align all walls and floors. Using the procedures described in Steps 4 through 7, block and level the light section of the home. Floors, ceilings and walls should meet along the entire marriage line. Once again, all contact areas must be checked for possible voids in the gasket and sealed as necessary. Under no condition should gaps larger than 3/4" be allowed between any of the framing members.

All Rights Reserved. SECTION 5 - SINGLE SECTION INSTALLATION Carefully operate all jacks simultaneously to prevent excessive stress to the unit and raise this side slightly higher- than the desired elevation. Place pier supports in front of and behind the axles. If the spacing of these piers exceeds the required spacing indicated in Table 1 or 2 as determined in Section 3, add a pier between the two axle piers. Removal of one or more axles may be necessary to comply with pier spacing requirements. Do not install piers under axles or at spring hanger locations. STEP 5: Repeat STEP 4 on the other main I-beam of the unit. STEP 6: Place the remaining supports under the main I -beams, maintaining proper spacing and support sizing previously determined in Sections 2 and 3. Also ensure that the centerline of the rear pier supports are located within 24" of the rear end of the unit. STEP 9: Perimeter supports are required under any sidewall offset or recessed condition. Supports may be necessary at areas -that -are subject -to extra weight or vibration such as laundry areas under the washer and dryer, and refrigerators or masonry front fireplaces that are located between the main I-beam and a perimeter joist. Install perimeter supports at exterior door openings that are less than 4'-0", unless door operates smoothly. Install perimeter supports at both sides of all exterior sidewall (not applicable to end walls) openings greater than 4'-0", such as large windows or a group of windows, sliding or French doors. STEP 10: If the unit is installed in a geographic area where perimeter blocking is required (as determined in Section 3), install them at the exterior perimeter joist at this time. The piers may be set back a maximum of 8", as shown in the detail below. STEP 7: Level the floor of the home by jacking. The solid concrete cap at the top EXTERIOR SIDEWALL of each pier should be within 2" of the main I-beam or perimeter joist. Use FLOOR DECKING combinations of 2", 4" and 8" blocks to MAIN I -BEAM achieve this condition. Using a water INTERIOR level, check the level of all piers and CROSSMEMBER adjust if necessary. Total thickness of the combined plates and shims should not exceed 3 1/4 inches. At all points along the I-beam, the elevation of the 8° lower flange of the I-beam should be ± e MAX. SEE APPLICABLE PIER DETAILS 3/8" and should not deviate more than 3/4" overall as measured by water level. STEP 8: Tape or repair any punctures or tears in the bottom board that may have occurred during positioning or jacking of the unit.

All Rights Reserved. SECTION 6 — TAG UNIT INSTALLATION STEP 1: Before attempting to attach the tag unit to the main unit, make sure the main unit has been completely blocked, leveled and anchored. STEP 2: Position the tag unit as close to the main unit as possible, at its intended location. Use the hitch jack to obtain approximate leveling. Install pier supports under the main I -beams no more than 24" from the front cross member. Blocking spacing, pier design and footer sizes are the same as for mother unit. Determine whether the tag and main unit floors are designed to line up or are step down from each other. Adjust the pier heights of the tag unit accordingly. STEP 3: Using a water level, check the level of all piers. At all points along the I -Beam, the elevation of the lower flange of the I-beam should be ±3/8" and should not deviate more than 3/4" overall as measured by water level. STEP 4: If the floor of the tag unit is level with main unit floor, connect the floors together as described in Section 4, Step 9. If the floors are offset from each other, use the following method: MAIN UNIT FLOOR TAG UNIT FLOOR FACTORY INSTALLED 1 1/2xl 1/2x3/16xl2 OR 1 1/2xl 1/2x11 GA. ANGLE IRON; TWO EACH END OF TAG UNIT, ONE IN CENTER OF TAG UNIT. STEP 5: Secure the tag unit end wall to the main unit sidewall per the following detail. Depending on the type of siding and/or which wind zone the tag unit was designed for, the sheathing shown in the detail may not be required. If required, the sheathing over the last stud bay was tacked in place for easy on site removal. Once the wall connections are complete, re -install sheathing and complete siding installation. TYP.

The strap should be through the buckle in this configuration BEFORE wrapping the strap around the I -Beam. b) •I -Beam Attachment: Next, bring long end of strap between I - Beam and floor of unit. Continue around the I-beam, thread through top notch of buckle for a second time and over the I - Beam to the anchor. Section 7, Anchoring, Page 4 A properly installed strap and buckle should look like the following detail. Be sure the end of the strap connecting to the anchor, departs from the top of the beam as shown. STEP 4. Anchor and Strap: Attach the other end of the strap to the anchor head per the following procedure: a) Insert bolt into head; attach nut to other side loosely. Bolt may be inserted from either side. b) Insert strap through slot in 5/8" diameter bolt. Push through slot at least to the far edge of the anchor head. c) Bend strap 90°. Use a socket wrench and take at least four COPYRIG O 2000 BY PALM HARBOR HOMES, INC. All Rights Reserved. SECTION 7 - ANCHORING b) Determine longitudinal ties required. Longitudinal ties are designed to resist net horizontal wind loads acting STEP 2. Mark all anchor locations to against the end wall of the home. They ensure no interference with other may or may not be required for Wind components such as piers, plumbing or Zones I, II or III depending on the heating/cooling ducts. Install anchors per home's length, width and height off the the anchor manufacturer's installation ground. Refer to the appropriate charts requirements. in this section. Longitudinal Stabilizing Devices, such as Tie Down Engineering's LSD or other equivalent systems, are the preferred method. For number of devices required, see Table 6 of this section. Note: some States may have prescriptive requirements, which may supersede manufacturer installation instructions. Conventional longitudinal anchoring systems which use ground anchors and straps may also be used, provided the connection of the strap to the unit Main I -beams provide for a pivoting strap connector to the beam. To determine the minimum number of longitudinal ties required per unit per end, using the conventional system, see Table 3.1 or 3.2 for Wind Zone I, Table 4.1 & 4.2 for Wind Zone II & III single section units and 5.1 & 5.2 for Wind Zone II & III multi section units. Note: some States may have prescriptive requirements, which may supersede manufacturer installation instructions. WARNINGM BEFORE YOU BEGIN, MAKE SURE TO INDICATE LOCATIONS OF ANY UNDERGROUND ELECTRICAL CABLES, GAS LINES, WATER AND/OR SEWER LINES, PRIOR TO ANCHOR INSTALLATIONS. FAILURE TO DO SO MAY RESULT IN SERIOUS PERSONAL INJURY OR EVEN DEATH. STEP 3. Installing diagonal tie downs: I -Beam Connection: Method I (preferred): connect the strap to the top flange of the main I -Beam using an approved clamping device. The device must also incorporate a swivel connection. These devices are available through Tie Down Engineering, Minute Man Anchors and other anchor equipment manufacturers/suppliers.

SECTION 7 - ANCHORING Federal Regulations require that Palm Harbor Homes provide an approved anchoring system, designed to transfer the design wind loads from the home to ground anchors. These anchoring devices are not provided by Palm Harbor Homes. Companies such as Tie Down Engineering, Inc., or Minute Man Anchors, Inc. as well as other comparable companies may be contacted to obtain approved anchoring equipment. To locate the nearest supplier of Tie Down Engineering, call toll free 1-800-241-1806 (www.tiedown.com). To locate the nearest supplier of Minute Man Anchors, call toll free 1-800-438-7277. Other anchoring systems are acceptable provided that the system has been designed by a registered professional engineer, or approved for the use intended by local authority having jurisdiction, and installed in accordance with those approved plans and specifications. Some State and/or Local zoning ordinances and/or State or local building codes may not require any anchoring systems, or may require additional anchoring requirements, based on the design wind loads prevalent in their respective areas. When the requirements are less stringent than those detailed in this manual, we suggest you follow the details in the manual. Consult with your installation contractor and/or dealer for any additional cost, if any. Palm Harbor Homes, Inc. claims no responsibility for the products used in setting up our homes unless we specifically supply these products. All anchoring devices must be installed in accordance with their listing. If your home (single- or multi -section) is designed for and installed in Wind Zone I, as previously determined from the Wind Zone Design Map in Section 1 and the DATA PLATE, only diagonal tie - down straps (a.k.a. "frame ties") are required, but, if vertical ties are factory installed, they must be connected to an approved anchor. Anchors and tie -downs are designed to prevent your home from sliding off the piers. To determine the number and spacing of the anchors and straps, refer to the tables in this section based on Wind Zone, unit width, pier height, anchor capacity and strap attachment. The tables are separated in the following categories: a) Single and Multi section units installed in Wind Zone I: TABLE 3 to 3.2 b) Single section units installed in Wind Zones H &III: TABLES 4.1 to 4.2 c) Multi section units installed in Wind Zones H & III: TABLES 5.1 to 5.2 d) Multi section, offset units Table 3.3 Wind Zone 1 Table 5.3 Wind Zone H&III Material specifications: I.)

SECTION 7 - ANCHORING withstanding a 50% overload (4725 lbs total). 2.) Anchors: Ground Anchors should be certified by a professional engineer, architect, and/or nationally recognized testing laboratory, and/or approved by the local authority having jurisdiction. In either case, the T minimum working load capacity should be at least equal to 3150 lbs. and capable of withstanding a 50% overload (4725 lbs. total). Anchors should be embedded below the frost line and at least 12" above the water table. 3.) Stabilizing devices: Unless required by the local authority having jurisdiction, approved stabilizing devices (steel plates) and/or other methods (concrete collars) need only be installed to resist lateral movements on anchors connected to diagonal ties only. 4.) Other approved systems: Other systems, specifically approved by Palm Harbor Homes or by the local authority having jurisdiction, may also be used. Please refer to addenda included with this manual or check with your local building department. STEP 1. a) Determine diagonal tie spacing requirements. If the home is designed and installed in Wind Zone 1, determine from Table 3, the maximum anchor spacing for the unit based on its floor widths and the height from the anchor head to the bottom of the floor. The first anchor from each end must be within 24" of that end. Important: on single section units, anchors MUST be opposite each other. Section 7, Anchoring, Page 2 Typ.
