SAFETY RULES 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Improper installation, adjustment, alteration, service or maintenance can cause property damage, bodily injury or death. If you do not understand these instructions or your local codes, call local authorities, a qualified installer, service agency, gas supplier, or the manufacturer. Do not install this fan type wall furnace in a recreational vehicle trailer or mobile home.
VENTING - CONTINUED More than 10’ 10’ Ridge 10’ or Less Height above any roof surface within 10’ horizontally 2’ Min. 2’ Min. Ridge 3’ Min. 3’ Min. Chimney Chimney FIGURE A This appliance is equipped with a blocked flue switch. This switch, when activated, will interrupt the electrical circuit between the transformer and the gas valve causing the main burner flame to extinguish. The main burner will not re-light until the blocked flue switch has been manually reset.
COMBUSTION AND VENTILATION AIR When installed, this gas appliance must be provided with fresh air for combustion, ventilation, and dilution of hot flue gases. The minimum required volume of the area where the appliance is installed should be 50 cubic feet per 1,000 btu/hr. If installed in an area of the home that is considered an unconfined space, the natural infiltration of air around windows and doors will be adequate.
USING ADJACENT STUD SPACE FOR ALL COMBUSTION AIR FROM OUTSIDE LOCATION AND SPECIAL PRECAUTIONS The wall furnace should be located near the center of the house for best heat distribution. HOLES CONNECTING TO VENTILATED ATTIC CEILING PLATE AIR GRILLE If the area where the appliance is to be installed contains carpeting, tile or combustible materials, other than wood flooring, the appliance shall be installed on a metal plate, wood panel or other non-combustible materials.
GAS ROUGH-IN Check local codes for requirements as to the size and type of gas line required. See Figure 5 for location of gas inlet holes in furnace cabinet. Compounds used on threaded joints of gas pipe should be resistant to the action of liquefied petroleum gases. The gas line joints must be checked for leaks. This should be done with a soap solution – watching for bubbles on all connections. NEVER USE AN EXPOSED FLAME TO CHECK FOR LEAKS.
INSTALLATION / WHEN RECESSED (UP TO 9-1/4”) STEP 1.Cut out floor plate between 2x4 studs, so heater will set flat on floor. STEP 2.Make electrical connection of 115 V. wiring into junction box provided on top of header plate. STEP 3.Attach the base plate (purchased with the vent pipe) to the header plate using two No. 8 sheet-metal screws through the pre-punched holes. See Figure B. STEP 4.Square up and nail header plate in place between 2x4 studs placed on 16” centers (14-3/8” between studs).
Installation of B-W Gas Vent for one-story buildings or for first floor of multi-story buildings. Ceiling plate spacers to center B-W Gas Vent in stud space nail securely at both ends. Firestop spacers supplied by manufacturer of B-W Gas Vent Installation of B-W Gas Vent for each subsequent ceiling or floor level of multistory buildings. Plate cut away to provide passage of B-W Gas Vent Plate cut away for full width of stud space to provide ventilation.

PILOT FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with an ignition device which automatically lights the pilot. Do not try to light the pilot by hand. B. BEFORE OPERATING smell all around the appliance area for gas.
PROPER BURNER FLAME OPERATION A proper flame will have a dark blue inner mantle that sits right on top of the burners with a lighter blue outer mantle rising above the burner, (See Figure 11). There may be some yellow where the pilot flame and burner flame meet. There is no primary air adjustment on the burner, and proper flame is assured since the correct manifold pressure and orificing has been done at the factory.
