Lighting Instructions 1. STOP! Read the safety information above. 2. Turn off all electrical power to the fireplace. 3. Turn the On/Off switch to “OFF” position, set the remote to OFF or set thermostat to lowest level. 4. Open control access panel. 5. Push in gas control knob slightly and turn clockwise to “OFF”. 10. Push the control knob all the way in and hold. Immediately light the pilot by repeatedly depressing the piezo spark ignitor until a flame appears. Continue to hold the control knob in for about one (1) minute after the pilot is lit. Release knob and it will pop back up. Pilot should remain lit. If it goes out, repeat steps 5 through 8. 6. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information above. If you do not smell gas, go to the next step. 7. Remove glass door before lighting pilot. (See Glass Frame Removal section). 8. Visibly locate pilot by the main burner. 9. Turn knob on gas control counterclockwise to “PILOT”. • 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. Turn the On/Off switch to “ON” position or set thermostat to desired setting. 14. Turn on all electrical power to the fireplace. 3/8" - 1/2" Euro SIT SIT NOVA Honeywell ............ . ..... .. . PILOT OFF OFF 3 4 5 1 2OFF Pilot To Turn Off Gas To Heater 3.

Symptom Possible Causes Corrective Action 1. Spark ignitor will not light A. Defective or misaligned electrode at pilot Using a match, light pilot. If pilot lights, turn off pilot and push the red button again. If pilot will not light - check gap at electrode and pilot-should be 1/8” to have a strong spark. B. Defective ignitor (Push Button) With the control knob in the pilot position, push the control knob all the way and hold. Check for spark at electrode and pilot. If no spark to pilot, and electrode wire is properly connected, replace the battery in the ignitor module and try again. Refer to Maintenance Section. If the problem still exists, replace the ignitor module box. 2. Pilot will not stay lit after carefully following lighting instructions A. Defective pilot generator (thermocouple), remote wall switch Check pilot flame. Must impinge on thermocouple/thermopile. NOTE: This pilot burner assembly utilizes both a thermocouple and a thermopile. The thermocouple operates the main valve operation (On and Off). Clean and or adjust pilot for maximum flame impingement on thermopile and thermocouple. B. Defective automatic valve 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. 3. Pilot burning, no gas to main burner A. Wall switch or wires defective Check wall switch and wires for proper connections. Jumper wire across terminals at wall switch, if burner comes on, replace defective wall switch.. If okay, jumper wires across wall switch wires at valve, if burner comes on, wires are faulty or connections are bad. B. Thermopile may not be generat1. Be sure wire connections form thermopile at gas ing sufficient millivoltage valve terminals are tight and thermopile is fully inserted into pilot bracket. 2. One of the wall switch wires may be grounded. Remove wall switch wires form valve terminals if pilot now stays lit, trace wall switch wiring for ground. May be grounded to fireplace or gas supply. 3. Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve. Should read 250-300 millivolts (minimum 150) while holding valve knob depressed in pilot position and wall switch “Off”. Replace faulty thermopile if reading is below specified minimum. C. Plugged burner orifice Check burner orifices for debris and remove. D. Defective automatic valve operator Turn valve knob to “On”, place wall switch to “On” millivolt meter should read greater than 150mV. If the reading is okay and the burner does not come on, replace the gas valve. 4. Frequent pilot outage problem A. Pilot flame may be too low or blowing (high) causing the pilot safety to drop out Clean and/or adjust pilot flame for maxi...
