C (0902) ROOF JACK NEW HOME INSTALLATION If this furnace is installed on a new home do the following: 1. Inspect the furnace top collars for signs of insulation or ceiling debris which might have fallen in during cutting of the ceiling and roof holes. Remove all debris before continuing. 2. Only use the appropriate roof jack. See Figures 6 & 7 for correct application. After unpacking the roof jack, check the rain caps. Insure they are not damaged, tilted or crooked. Do not twist, crush or sit on the roof caps during installation. Damaged roof caps will cause improper furnace operation. The furnace will not heat properly and could result in explosion. 3. Do not exceed the maximum height as determined from Figures 6 & 7. Installer should allow an additional 1-1/2" travel before the flue pipe assembly is fully extended against the built-in stop. This provides an additional safeguard against the flue assembly being pulled from the roof jack during transportation or other stress conditions. Before inserting the vent pipe into the furnace top, inspect the furnace flue and combustion air opening for debris or insulation which have fallen in during pre-installation steps. Do not proceed unless all debris have been cleaned out or removed. 4. After installing roof jack on furnace top collar, check to make sure there is no gap in back or side between the pipe collar and the furnace casing top. If necessary to prevent excessive air leakage, the installer should seal joints in the combustion air tube with aluminum type or other suitable sealant. Failure to follow all venting instructions can result in fire, asphyxiation, or explosion. EXISTING FURNACE REPLACEMENT If this furnace replaces an existing furnace, do the following: INSTALLATION IN SNOW REGIONS 1. If a 2nd roof, roof cap or addition has been made to the existing roof of the home, remove the old roof jack completely! To avoid the possibility of an improperly installed pipe or gaps in the old roof jack, INSTALL A NEW ROOF JACK. Your ceiling and roof height will determine the correct roof jack to use. Refer to the vent selection table, of the furnace installation instructions. When the combustion air pipe inlet is covered or blocked with snow, the furnace will not operate properly due to the depleted combustion air supply. After unpacking the roof jack, check the rain caps. Insure they are not damaged, tilted or crooked. Do not twist, crush or sit on the roof caps during installation. Damaged roof caps will cause improper furnace operation. The furnace will not heat properly and could result in explosion. LOCATING AND CUTTING ROOF JACK OPENING 2. 3. Before inserting the roof jack into the furnace top, inspect the furnace flue and combustion air opening for debris or insulation which might have fallen in during preinstallation steps. Do not proceed unless all debris has been cleaned out or removed. 4. After installing roof jack on furnace top collar, check to make sure there is no gap in back or side between the pipe collar and the furnace casing top. 5. Use only the pipes provided with the roof jack assembly. Do not add to or adapt other sheet metal pipes. Do not cut, insert or add other pipes to this assembly. 6. 6 In no case should there be a gap between sections of the flue pipe or the combustion air pipe. If necessary to prevent excessive air leakage, the installer should seal joints in the combustion air tube with aluminum type or other suitable sealant. Therefore, if the furnace will be located in regions where snow accumulation on the roof exceeds 7" or in H.U.D. Snow Load Zones, a roof jack extension (Part No. 7680B6541) is recommended. To facilitate the proper installation of the roof jack, it is very important that the roof jack opening in the ceiling and roof be on the same vertical center line as the furnace flue collar. See Figure 9. Mark this location on ceiling and scribe a circle with a 5" radius (10" diameter) around this mark. Cut opening for roof jack through ceiling and roof. (If furnace was installed during construction, cover furnace and flue opening to prevent debris from entering flue when hole is cut for roof jack.) INSTALLING ROOF JACK IN ROOF (See Figure 6 & 7 for Dimensional requirements.) Insert roof jack into opening in the roof. The roof jack should be secured to the furnace before roof flange (flashing) is secured to the roof. This will insure a better alignment of the flue pipe and furnace flue collar. Caulk around and under roof flange to provide a water tight seal, before securing roof jack flashing to roof. Unitary Products Group 035-16328-002 Rev.

If sealant was not used, the installer should tape the mating flanges to provide a good air seal. NOTE: Duct sealant and tape must be classified as meeting HUD Standard 3280.715, U.L. Standard 181A. If tape is used to provide a better air seal, it should be a type approved by the applicable national or local codes. 10 The duct connector is designed for use on ducts down to 12" in width. When using the connector on smaller width ducts, there will not be sufficient clearance to bend the tabs on two sides of the duct connector. In such cases the tabs may be attached to the sides of the duct by using sheet metal screws or other suitable fasteners. Holes for sheet metal screws are provided in three (3) tabs on each side of the duct connector. If more than 3 tabs need to be used to provide a more secure and air tight connection, the remaining tabs can also be fastened to the duct with screws after drilling the required screw holes.

Secure all connections with suitable wire nuts and wrap with electrical tape. 4. Connect the “ground" wire to the grounding screw. 5. Reinstall the control panel cover and secure mounting screw. Eighteen gauge thermostat wire is highly recommended. Smaller gauge thermostat wire may be used only if the guideline below is followed. THERMOSTAT WIRE LENGTH (FURNACE TO THERMOSTAT) THERMOSTAT WIRE GAUGE 0 - 45 feet 0 - 70 feet 22 20 Do not use thermostat wire smaller than 22 gauge. If thermostat wire smaller than 18 gauge is used, pay particular attention that the connections between the different wire sizes are tight. Operational problems may be caused by loose connections or by the use of thermostat wire that is too small to carry the required load. Any such problems are the responsibility of the installer. A separate 115 V.A.C. supply circuit must be used for the furnace. The circuit should be protected by a 15 amp fuse or circuit breaker.

C (0902) GAS PIPING INSTALLATION AND CHECKING OF GAS LINE Gas Supply piping must be sized in accordance with the recommendations contained in National Fuel Gas Code (ANSIZ223.1, NFPA-54) unless local codes or regulations state otherwise. Materials used and pipe sizing for U.S. manufactured homes must comply with requirements contained in Manufactured Homes A119.1, Recreational Vehicles A119.2 and H.U.D. Title 24, Section 3280.705 and any local or state codes. NOTE: The gas line inlet on the gas valve is 1/2-14 N.P.T. The gas line may be installed through the furnace floor or furnace side to the gas valve. To install gas line and to connect it to the gas valve, care must be taken to hold gas valve firmly to prevent misalignment of the burner orifice, or to damage gas valve which could result in improper heating, explosion, fire or asphyxiation. DO NOT USE EXCESSIVE PIPE SEALANT ON PIPE JOINTS. Pipe sealant, metal chips or other foreign material that could be deposited in the inlet of the gas valve, when gas pipe is installed or carried through the gas piping into the gas valve inlet after installation, may cause the gas valve to malfunction and could result in possible improper heating, explosion, fire or asphyxiation. Also, pipe sealant must be resistant to Propane gas. For natural gas operation, the furnace is designed for 7" W.C. inlet gas pressure. Pressure to main burner is then reduced to 3 1/2" W.C. For Propane gas operation, the furnace is designed for 11" W.C. inlet gas pressure. Pressure to main burner is then reduced to 10" W.C. IMPORTANT - When converting gas valve from or to Propane gas, it will be necessary to change main burner orifice to prevent an underfired or overfired condition. See label inside lower furnace door for complete instructions. Pilot Adjustment On models equipped with standing pilot ignition, the pilot should be adjusted so that the flame is approximately 1” in height (500 BTU / hr.). This will allow proper burner ignition without excessive fuel usage. The pilot adjustment screw is located on the top of the gas valve. Observing Burner Operation 1. Observe burner to make sure it ignites. Observe color of flame. On natural gas the flame will burn blue with appreciably yellow tips. On Propane gas a yellow flame may be expected. If flame is not the proper color call a qualified service technician for service. 2. Let furnace heat until blower cycles on. 3. Turn thermostat down. 4. Observe burner to make sure it shuts off. 5. Let the furnace cool and blower cycle off. Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the furnace and allow burner to run until furnace cools down and blower shuts off before shutting off the electrical supply. Where regulations require, a main shut-off valve shall be installed externally of furnace casing. After piping has been installed, turn gas on and check all connections with a leak detector or soap solution. Never use open flame to test for gas leaks as fire or explosion could occur. Do not test the fuel system at more than 14" W.C. after furnace has been connected to fuel line. Such testing could void the warranty. Any test run above 14" W.C. may damage furnace control valve which could cause an explosion, fire or asphyxiation. If the gas input to the furnace is too great because of excessive gas pressure, wrong size orifice, high altitude, etc., the burner flame will be sooty and may produce carbon monoxide, which could result in unsafe operation, explosion, and/ or fire or asphyxiation. A dirt leg may be required by some local codes to trap moisture and contaminations. Unitary Products Group If any abnormalities are observed when checking for correct operation, such as burner failing to ignite or to turn off, sooty flame, etc., call your nearest authorized service technician as shown in the Service Center List included in the home owner envelope with the furnace. If Furnace Fails to Operate Properly 1. Check setting of thermostat - and position of HEAT/ COOL switch if air conditioning is installed. If a set-back type thermostat is employed be sure that the thermostat is in the correct operating mode. 2. Check to see that electrical power is ON. 3. Check to see that the knob or switch on the gas control valve is in the full ON position. 4. Make sure filters are clean, return grilles are not obstructed, and supply registers are open. 5. Be sure that furnace flue piping is open and unobstructed. If the cause for the failure to operate is not obvious, do not attempt to service the furnace yourself. Call a qualified service agency or your gas supplier. 19 035-16328-002 Rev. C (0902) FINAL PROCEDURE FURNACE AND AIR CONDITIONER INSTALLATIONS INSTALL FURNACE DOORS Install the lower door first by sliding the bottom of the door down until the tabs on the casing base engage the slots in the bottom door end cap. Then push the top of the lower door in until the door clips snap into place. Install the upper door in a similar manner, first engaging the slots in the top of the upper door on the tabs on the casing top. Then snap the bottom of the upper door into place against the casing. FINISH AND TRIM Alcove and Closet Installations may now be finished and trimmed as necessary. If an air conditioner is installed which does not use the blower for air distribution and operates completely independent of the furnace, the thermostat system must have an interlock to prevent the furnace and air conditioner from operating at the same time. This interlock system usually contains a heat-cool switch which must be turned to either HEAT or COOL to activate either heating or cooling operation, or a positive OFF switch on the cooling thermostat. When used in connection with a cooling unit the furnace shall be installed parallel with or on the upstream side of the cooling unit to avoid condensation in the heat exchanger. For installations with a parallel flow arrangement, the furnace must be equipped with a damper to prevent cold air from being discharged up around the heat exchanger. Cold air causes condensation inside the exchanger and can cause it to rust out which can allow products of combustion to be circulated into the living area by the furnace blower resulting in possible asphyxiation. An air flow activated automatic damper, P/N 7900-6771, is available from furnace manufacturer. See Figure 24. AUTOMATIC DAMPER NOTE: See label on coil panel for conversion and lighting instructions. Obtain a temperature rise within the ranges specified on the name plate.
