• If knob does not pop up when released, stop and immediately call your service technician or gas supplier. • If after several tries, the pilot will not stay lit, turn the gas control knob to "OFF" and call your service technician or gas supplier. 11. Replace glass door. 12. Turn gas control knob to “ON” position. 13. For RN/RP appliances turn the On/Off switch to “ON” position or set thermostat to desired setting. 14. Turn on all electrical power to the fireplace. Euro SIT SIT NOVA Honeywell PILOTON OFF ON PILOT OFF OFF 3 4 5 1 2OFF Pilot 3/8" - 1/2" To Turn Off Gas To Heater 3. Open control access panel. 4. Push in gas control knob slightly and turn clockwise to "OFF". Do not force. 5. Close control access panel. 1. Turn the On/Off switch to Off position or set the thermostat to lowest setting. 2. Turn off all electric power to the fireplace if service is to be performed. Pinnacle & Stardance Direct Vent - Rear Vent Gas Heaters Troubleshooting / Honeywell #8420 Gas Control System NOTE: Before troubleshooting the gas control system, be sure the external gas shutoff is in the “ON” position. WARNING: REMOVE THE GLASS PANEL BEFORE PERFORMING ANY GAS CONTROL SERVICE WORK. SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION 1. Spark ignitor will not light 2. Pilot will not stay lit after carefully following the lighting instructions 3. Pilot lights, no gas to burner, valve knob ON, remote switch (rocker switch) ON 4. Frequent pilot outage A. Defective or misaligned electrode at the pilot B. Defective ignitor (push button) A. Defective pilot generator (thermocouple) B. Defective automatic valve operator A. Remote switch or wires defective B. Thermopile may not gener- ate sufficient voltage C. Plugged burner orifice D. Defective automatic valve operator A. Pilot flame may be too low or high, (blowing or lifting), causing the pilot to drop out B. Possible blockage of the vent terminal Using a match, light pilot. If pilot lights, turn off pilot and push the ignitor button again. If pilot will not light, check gap at electrode and pilot - it should be 1/8” to have a strong spark. Push piezo ignitor button. Check for spark at electrode and pilot. If there is no spark at the pilot, and electrode wire is properly connected, replace ignitor. Check pilot flame. It must impinge on the thermocouple or thermopile. NOTE: This pilot burner assembly uses both a thermocouple and a thermopile. The thermo- couple operates the pilot flame. Tighten the thermo- couple. The thermopile operates the main valve (ON and OFF). Clean and/or adjust pilot for maximum flame impingement on thermocouple and thermopile. Turn valve knob to ‘Pilot’. Maintain flow to pilot; millivolt meter should read greater than 10mV. If the reading is okay and the pilot does not stay on, replace the gas valve. NOTE: An interrupter block (not supplied) must be used to conduct this test. Check rocker switch and wires for proper connection. Use jumper wires across terminals at rocker switch. If burner lights, replace rocker switch. If okay, use jumper wires across rocker switch wires at the valve; if burner lights, wires are faulty or connections are bad. 1. Be sure wire connections from thermopile at gas valve terminals are tight and thermopile is fully inserted into pilot bracket. 2. One of the rocker switch wires may be grounded. Remove rocker switch wires from valve terminals. If burner now stays lit, trace rocker switch wiring from ground. It may be grounded to the appliance or the gas supply line. 3. Check the thermopile with a millivolt meter. Take reading at thermopile (“TP” and “TP/TH”) terminals of gas valve. Should read 325 millivolts minimum while holding valve knob depressed in PILOT position and with rocker switch OFF. Replace faulty thermopile if reading is below specified minimum. Check burner orifices for debris, and remove. Turn knob to ON, place rocker switch to ON, millivolt meter should read greater than 10 mV. If the reading is okay and the burner does not light, replace the valve. Clean and/or adjust pilot flame for maximum flame impingement on thermocouple and thermopile. Check the vent terminal for blockage. Pinnacle & Stardance Direct Vent - Rear Vent Gas Heaters Instructions for RF Comfort Control Valve The Comfort Control Valve allows remote control of temperature, fan and flame appearance. NOTE: The antenna should hang in free air away from grounded metal. Operation 1. If the manual switch is in remote position, switch it to LOCAL. (Fig. 53) 2. Turn the pilotstat knob counterclockwise from OFF to the PILOT position, push the knob down, and hold in position. The pilot valve opens and allows gas to flow to the pilot burner. 3. Push plunger on the piezo until the pilot burner is lit. When the pilot burner is lit, the LED on the control will come on after approximately 40 seconds and will provide 1 short blink continuously in the normal mode. When the light turns off which will be approximately 10 seconds after it has been continuously red, the recei...
