for gas, including near the floor. If you smell gas, STOP! Follow “B” in the information on the safety label. If you don’t smell gas, go to the next step. TO TURN OFF GAS TO APPLIANCE 1. Turn thermostat to it’s lowest setting. 2. Turn off all electric power to the appliance if service is to be performed. 3. Remove cabinet door. 4. Push in gas control lever slightly and slide to “OFF”. Do not force. 5. Replace cabinet door. Page 9 PILOT ADJUSTMENT Locate the pilot adjustment screw on the valve. The pilot flame should surround at least the top 3/8” of the powerpile (pilot generator) or flame sensor (see Figure 7). The pilot is unregulated so it will be operating at inlet line pressure (Max. 7” w.c. for Natural Gas and 11” w.c. for Propane). To decrease the pilot flame, turn the screw clockwise (approximately six full turns to bottom of pilot light channel) until you produce sufficient flame at the minimum noise level. PILOT FLAME ADJUSTMENT: Pilot flame should envelop 3/8 to 1/2 inch of the tip of sensor. 3/8” to 1/2” 3/8” to 1/2” FIGURE 7B I.I.D. PILOT FIGURE 7A STANDING PILOT Pilot Adj. Screw Pilot Adj.

Turn thermostat to lowest setting and allow furnace to cool. 2. Turn off all electric power to furnace. 3. Remove lower grille. 4. Disconnect gas supply to valve. 5. Disconnect wires from gas valve. 6. Remove 15 screws holding burner door to burner box. Pull door forward to remove complete burner, gas valve assembly. 7. After inspecting and cleaning, place burner assembly back into burner box and tighten 15 screws. NOTE: Be sure door gasket is not damaged and will effect a proper seal or pilot outage will occur. 8. Connect wires back to valve. 9. Connect gas supply back to valve. 10. Turn on electric to furnace. 11. Follow lighting instructions, and replace lower grille. It is recommended that the furnace and all components be inspected at least annually by a qualified service person. This should include the burner, pilot, heat exchanger, and vent system. Be sure that the flow of combustion and ventilation air is not obstructed. IMPORTANT: Keep burner and control compartment clean. Vacuum control compartment at the start of the heating season and as often as needed. PROPER BURNER FLAME The burner flame may be observed by raising the sight glass cover. 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 8). 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. NOTE: It is advised that the burner flames be checked at least twice during the heating season for any changes in burner flame characteristics. The appliance area must be kept clear and free from combustible materials, gasoline, and other flammable vapors and liquids. This heater comes from the factory with the proper burner orifice for elevations up to 2,000 feet. Heaters installed above 2,000 feet must be derated 4% for every 1,000 feet. For the proper orifice size, find the Model Number and elevation on the orifice chart. Replace burner orifice.
