11. TROUBLE SHOOTING

Problem	Possible Cause	Solution
Spark will not arc to the pilot after	Defective piezo ignitor	Check connections to ignitor
repeated pressing of spark ignitor		-If ignitor connections are good but there is no
		spark-replace ignitor
	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 away from burner 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 rear of valve-
		must be greater than 5 mV. If low , replace
		thermocouple.
	Air in gas line - (Pilot flame dies while	-Bleed line.
	knob is depressed.)	-Check gas line pressure.
		-Contact dealer.
Burners will not remain lit	Problem with thermopile circuit	-Check gasline 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.
		BV only: - Check for spillage at draft hood that
		may trip spill switch.
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.
BV only: insufficient air for	- Air tight house	- supply make up air to the unit.
combustion	- A Vacuum in room due to other air
	moving device
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 Sooting	Flame impingement	-check log position
		-increase primary air by opening venturi
		shutters
		see also “Burners will not stay lit”
