Check the thermopile with a millivolt meter. Take the reading at THTP& TP terminals of the gas valve. The meter should read 350 millivolts minimum, while holding the valve knob depressed in the pilot position, with the pilot lit, and the ON/OFF switch in the OFF position. Replace the thermopile if the reading is below the specifi ed minimum. With the pilot in the ON position, disconnect the thermopile leads from the valve. Take a reading at the thermopile leads. The reading should be 350 millivolts minimum. Replace the thermopile if the reading is below the minimum. Heat & Glo • 8000TV-OAK, 8000TV-OAK-IPI, 8000TVLP-OAKIPI • 2058-900 Rev. N • 11/08 Troubleshooting (continued) Symptom Possible Cause Corrective Action 3. (Continued) C. Back drafting may be tripping the spill switch. Negative pressure, wind or flue blockage may be causing spillage. Perform negative pressure diagnostics and inspect venting. D. Valve. Turn the valve knob to the ON position. Place the ON/ OFF switch in the ON position. Take a reading with a millivolt meter at the thermopile terminals. The millivolt meter should read greater than 125mV. If the reading is acceptable, and if the burner does not come on, replace the gas valve. E. Plugged burner orifice. Check the burner orifice for stoppage. Remove stoppage. F. Wall switch or wires. Check the wall switch and wires for proper connections. Place the jumper wires across the terminals at the wall switch. If the burner comes on, replace the wall switch. If the wall switch is OK, place the jumper wires across the wall switch wires at the gas valve. If the burner comes on, the wires are faulty or connections are bad. 4. Frequent pilot outage problem. A. Pilot flame may be too high or too low, or blowing out (high pressure), causing pilot safety to drop out. Clean thermocouple and adjust the pilot flame for proper flame impingement. Follow lighting instructions carefully. 5. The pilot and main burner extinguish while in operation. A. No LP in tank. Check the LP (propane) tank. Refill the fuel tank. B. Improper gas inlet pressure. Natural gas should be 5-14 in. w.c. LP should be 1014 in. w.c. Verify pressure with manometer. C. Inner vent pipe leaking exhaust gases back into the system. Check venting system for damage. Replace/repair improperly assembled pipe sections. D. Glass installed improperly. Check to ensure glass is installed properly. Replace fixed glass panel assembly. E. Thermopile or thermocouple. Replace pilot if necessary. F. Improper vent cap installation. Check for proper installation and freedom from debris or blockage. 6. Glass soots. A. Flame impingement. Adjust the log set so that the flame does not excessively impinge on it. Refer to log instructions. B. Improper air shutter setting. Refer to manual for shutter set points. Ensure that set point is correct for appliance/gas type. If unit has adjustable shutter, it may be necessary to increase shutter opening. C. Debris around air shutter. Inspect the opening at the base of the burner. NO MATERIAL SHOULD BE PLACED IN THIS OPENING. 7. Flame burns blue and lifts off burner. A. Insufficient oxygen being supplied. Ensure that the vent cap is installed properly and free of debris. Ensure that the vent system joints are tight and have no leaks. Ensure that no debris has been placed at the base of, or in the area of the air holes in the center of the base pan beneath the burner. Ensure that the glass is tightened properly on the unit, particularly on top corners. Heat & Glo • 8000TV-OAK, 8000TV-OAK-IPI, 8000TVLP-OAKIPI • 2058-900 Rev. N • 11/08 B. Intellifire Ignition System Symptom Possible Cause Corrective Action 1. Pilot won’t light. The ignitor/module makes noise, but no spark. A. Incorrect wiring. Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are connected to correct terminals on module and pilot assembly. B. Loose connections or electrical shorts in the wiring. Verify no loose connections or electrical shorts in wiring from module to pilot assembly. Verify connections underneath pilot assembly are tight; also verify connections are not grounding out to metal chassis, pilot burner, pilot enclosure, mesh screen if present, or any other metal object. C. Ignitor gap is too large. Verify gap of igniter to right side of pilot hood. The gap should be approximately .17 in. or 1/8 in. (3 mm). D. Module. Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor wire “I” from module. Place a grounded wire about 3/16 in. (5 mm) away from “I” terminal on module. Place ON/OFF rocker switch or wall switch in ON position. If there is no spark at “I” terminal module must be replaced. If there is a spark at “I” terminal, module is fine. Inspect pilot assembly for shorted sparker wire or cracked insulator around electrode. Replace pilot if necessary. 2. Pilot won’t light, there is no noise or spark. A. No power or transformer installed incorrectly. Verify that transformer is installed and plugged into module...
