FIGURE 13 : Installation of Furnace INSTALLATION OF THE FURNACE Remove the front panels and set the fumaca onto the duct connector. Slide it back until the rear of the unit engages the Iocator bracket. 2. Secure the front of the furnace with two screws at the mounting holes provided. 3. Secure the top of the furnace to a structural member using screw through the strap at the back of the furnace. Strap may be moved to any of the holes located along the top back of the furnace. Installer may provide an equivalent method, such as screws through the casing side. COMBUSTION LA, CAUTION] The inner flue pipe must be present. It is mandatory that the combustion air pipe and flue pipe assembly be fully engaged. The combustion air pipe MUST be securely fastened to the furnace with a sheet metal screw in the hole provided. Use a 1/2" blunt or sharp end sheet metal screw to fasten roof jack combustionair pipe to furnace combustion air colla_ Screw hole is provided in the pipe and collar Excessively long screws may extend to flue pipe and puncture it. Screws are not to exceed 1 1/2"in length. NOTE: Combustion air tube and flue pipe are part of the same assembly. Only the combustion air tube need be fas tened to the furnace. 1. Check to be certain that the flue pipe and combustion air tube are present. 2. Pull the telescoping flue tube and combustion air tube assembly down from the roof jack. Slide the flue tube/ combustion air tube assembly down firmly over the fur nace flue outlet and combustion air cellar. Insure that the back, side and front of combustion air tube collar is fully engaged and is in contact with gasket, Fasten the combustion air tube to the furnace combustion air collar usinga 1/2 inchsheet metal screw. (Screw hole provided in combustionair tube and fumaca combustionair collar. See Figure 14. It is mandatory that the combustion air and flue tube assembly be fully engaged at back sides and front, and combustion air SECURE STRAP tube securely fastened to the fumace with a sheet metal screw TO WALL_ in the screw hole provided, COMBUSTION FRONT OF FURNACE #8 OR #10 SCREW RECOMMENDED FIGURE 14 : Connecting Roof JAck to Furnace Unitary Products Group 035-16328-092 Rev. C (0902) CEILING RINGS The coiling ring is to meet fire stop requirements. Accessory Ceiling Ring (PIN 7660-2841) may be used, (See Figure 15) or the manufactured home manufacturer or the installer may use other approved methods to stop fire. If required, three (3) sections of Accossory Ring may be used as shown in Figure 15 to provide closer clearance around roof jack, A B FIGURE 15 : Ceiling Rings ELECTRICAL WIRING IlIA CAUTIiQN TO INSTALLER: Incoming power must be polarized. Observe color coding. AWARNING! SHOCK HAZARD -DISCONNECT ELECTRI CAL POWER SUPPLY TO THE UNIT BEFORE SERVICING TO AVOID THE POSSIBILITY OF SHOCK INJURY OR DAMAGE TO THE EQUIPMENT CONNECT POWER SUPPLY WIRES 1. Remove the field wiring cover. 2, Insert 115 volt wires through the large plastic bushing on the left side of the furnace (See Figure 16). If conduit is used it should be secured to the control box. 3. Connect the "hot" wire to the BLACK pigtail lead, and the "neutral" wire to the WHITE pigtail lead. 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, CONNECT THERMOSTAT WIRES 1. Insert 24 voltwires throughthe smallplastic bushing just above the control panel. 2. Connect the thermostat wires to the furnace low voltage pigtails...
