Page 12 12431-9-0408 PILOT FLAME CHARACTERISTICS The correct pilot flame (Figure 11) will be blue, extending past PROPER FLAME ADJUSTMENT the thermocouple. The flame will surround the thermocouple just below the tip. Natural gas pilots require adjusting when the inlet gas pressure is above 5" w.c. Remove the pilot cover screw on the control valve (Figure 3, page 8), and turn the adjustment screw clockwise to reduce flame. Replace pilot cover screw to eliminate gas leaking at that control valve opening. LP gas (propane) will not require adjustment. After use, cleaning may be required for the proper flame. Figure 11 MAIN BURNER FLAME CHARACTERISTICS The correct flame will be a short blue inner flame with a much larger light blue outer flame. The main burner (Figure 12) shows the approximate height of each part of the flame for each gas. The burner does not have a primary air adjustment. The flame will be correct if the factory-set pressure and orifice opening are used. After the furnace has been operating, the burner ports may be blocked by foreign matter carried in by combustion air. Therefore, cleaning of the burner may be needed for proper flame. To clean burner port disconnect the gas supply to the valve, and remove the eight screws fastening the burner door. After removing the burner door from the combustion chamber, remove rear burner, pilot burner and front burner. With front and rear burners removed from furnace, force water into the ribbon ports and dry with air pressure. Figure 12 12431-9-0408 Page 13 WIRING Wiring The appliance, when ...
