TROUBLE SHOOTING

Problem	Possible Cause	Solution
Spark will not light the pilot after	Defective piezo igniter	Check connections to igniter
repeated pressing of spark igniter		-If igniter connections are good but
		there is no spark-replace igniter
	Broken spark electrode	-Check for broken ceramic insulation
		replace, electrode if broken
	Miss-aligned spark electrode	-If spark is not arcing from the
		electrode to pilot- adjust by loosening
		screws on pilot base. Adjust and re-
		tighten
Pilot will not remain lit	Problem with thermocouple circuit	-Check for proper connection of
		thermocouple to rear of valve. If
		loose, tighten lightly
		-Check pilot for full flame
		impingement around thermocouple.
		If the pilot is to small - Check gas
		pressure, adjust pilot rate screw,
		check pilot head for blockage.
		-Check thermocouple voltage at
		valve- must be greater than 5 mV. If
		low, replace thermocouple.
	Air in gas line - (Pilot flame dies while knob	-Bleed line.
	is depressed.)	-Check gas line pressure.
		-Contact dealer.
Burners will not remain lit	Problem with thermopile circuit	-Check gas line pressure.
		-Check for flame impingement on
		thermopile, if low see “Pilot will not
		stay lit”
		-Check thermopile for a Minimum of
		220 mV	when burner 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
	Terminal may be recirculating flue gases	manual
		-Check to see if terminal is on
		correctly
		-May need to install high wind
		termination cap
		-Contact dealer.
Glass fogs up	Normal conditions - after the appliance warms	up glass will clear
	** Due to additives in gas, glass may get hazy during normal use**
	Clean when needed.
Blue flames	Normal during start - flame will yellow as the
	appliance heats up.
Flames are burning “dirty” or	Flame impingement	-Check log position
Sooting		-Increase primary air by opening
		venturi shutters
