Anleitung Zusammenfassung
To clean burner ports, disconnect the gas supply to the valve. Remove the burner assembly from the combustion chamber. Remove pilot burner from main burner and then remove the main burner. Force water into the ports and blow dry with vacuum cleaner air, or low pressure compressed air. The correct flame will be blue, extending past the thermopile. The flame will surround the thermopile just below its tip. Natural gas pilots require adjusting when the inlet gas pressure is above 5" w.c. (1.245kPa). Remove the pilot cover screw on the control valve 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. Examine the pilot flame before and during each heating season. PROPER PILOT FLAME Figure 9 Figure 10 TROUBLESHOOTING GENERAL All furnaces have been fire-tested to check for proper operation. This includes main burner flame, pilot flame, and gas control operation. If the furnace fails to function on initial installation, it is advisable to re-check the following: 1. Inlet gas pressure. 2. Type of gas being used and that shown on the rating plate. The Service Department at Empire Comfort Systems, Inc. may be contacted to assist in servicing furnace. Servicing the Pilot and Main Burner, Pilot Orifice, Thermopile and Main Burner Orifice Disconnect the gas supply at the inlet to the control valve. Remove the burner assembly to which the above components are attached. Pilot Does Not Light With air in the gas line, such as when the furnace is first installed or was "OFF" all summer, the pilot flame may be too lean to ignite on the first few trials. Turn the gas control knob to PILOT position and depress the gas control knob. Hold the gas control knob down to bleed the line; 1. Use lighter rod to light pilot with a match. If Pilot Does Not Light By Any Means 1. Check gas control knob for being in the "Pilot" position. 2. Checkpilotadjustmentforbeingfullopen(counterclockwise to open). 3. If gas is available in the supply tubing, the pilot orifice and/or pilot burner is probably restricted by a spider web. Clean pilot assembly and relight. If Pilot Does Not Remain "On" After Releasing Gas Control Knob 1. Follow instructions and hold gas control knob down longer and harder. 2. Determine if pilot flame extends past thermopile; if not, adjust pilot flame or clean pilot burner. 3. Replace thermopile if millivolt reading is less than 300 millivolts when wall thermostat or remote bulb is turned OFF. Replace gas control if magnet dropout millivolt reading is over 100 millivolts. Pilot Outage During Normal Operation 1. Check input by manifold pressure gauge or gas meter. 2. Check millivolt output when furnace is in operation. If millivolt output decreases during furnace operation gas control may be defective. Main Gas Valve Does Not Open When Thermostat Is Turned "On" 1. Check millivolt output of thermopile. 2. Thermostat wires may be broken. 3. Thermostat may be defective. Page 14 12425-7-0406 PARTS LIST ATTENTION: When ordering parts, it is very important that part number and description of part coincide.
