Troubleshooting

Problem	Possible Cause	Solution
Spark will not light the	Defective piezo ignitor	• Check connections to ignitor.
pilot after repeatedly		• If ignitor connections are good but no spark, replace
pressing the spark ignitor		ignitor.
	Broken spark electrode	• Check for broken ceramic insulation, replace
		electrode if broken.
	Misaligned spark electrode	• If spark is not arcing from electrode to pilot, adjust
		by loosening the screws on the pilot base. Adjust and
		tighten.
Pilot will not remain lit	Problem with thermocouple	• Check for proper connection of the thermocouple to
	circuit	the rear of the valve; if loose fully tighten.
		• Check pilot for full flame impingement around
		thermocouple. If flame is too small, check gas
		pressure, adjust pilot rate screw, check pilot head for
		damage.
		• Check thermocouple voltage at valve. It must be
		greater than 5mV. If low, replace thermocouple.
	Air in gas line (pilot dies	• Bleed line.
	while knob is depressed)	• Check gas line pressure.
		• Contact dealer.
Burners will not remain	Problem with thermopile	• Check gas line pressure .
lit	circuit	• Check for flame impingement in thermopile. If low,
		see “Pilot will not remain lit”.
		• Check thermopile for minimum of 300mV when
		burner is switched on.
		• Check wiring to thermostat for breaks.
Flame lifting	Leak in vent pipe	• Check for leaks in vent connections.
	Improper vent configuration	• Check vent configuration with manual.
	Terminal may be	• Check to see if terminal is on correctly.
	recirculating flue gases	• May need to install high wind termination cap.
		• Contact dealer.
Glass fogs up	Normal Condition: after the appliance warms up the glass will clear.
	**Due to additives in gas, glass may get hazy during operation** Clean as needed.
Blue Flames	Normal during start up: flames will yellow as the fireplace heats up.
Flames are burning	Flame impingement	• Check log positioning.
“dirty” or sooting		• Increase primary air by opening the venturi shutter
		and/or by opening the vent restrictor.
		See also “Burners will not stay lit”.
Remote control doesn’t	Problem with the remote	• One or more of the batteries are dead. See remote
work		control instructions.
	Problem with fireplace	• The on/off switch is turned to OFF.
		• The gas control valve is turned to PILOT or OFF.
		• The pilot has gone out.
