TROUBLE SHOOTING

Problem	Possible Cause	Solution
Spark will not light the pilot after	Defective piezo igniter	Check connections to igniter
repeated pressing of spark		-If igniter connections are good but
igniter		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	-Bleed line.
	while knob 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
		300 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 manual
	Terminal may be recirculating flue	-Check to see if terminal is on correctly
	gases	-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
	the appliance heats up.
Flames are burning “dirty” or	Flame impingement	-Check log position
Sooting		-Increase primary air by opening
		venturi shutters
		See also “Burners will not stay lit”
Flame goes out / comes on	Improper placement of	Move bulb to cooler location
frequently during a short period	thermostatic bulb
of time
