Trouble Shooting
Problem Possible Cause Solution
Spark will not light
the pilot after
repeatedly pressing
the spark ignitor
Defective piezo ignitor. • Check connections to ignitor.
• If ignitor connections are good but no spark,
replace ignitor.
Broken spark electrode. • Check for broken ceramic insulation.
• Replace electrode if broken.
Low battery or bad
electronic module.
• Replace the electronic module.
• Replace the battery in module.
Misaligned spark
electrode.
• If spark is not arcing from electrode to pilot - adjust
by loosening the screws on the pilot base. Adjust
away from burner and retighten.
Pilot will not remain
lit
Problem with
thermocouple circuit.
• Check for proper connection of the thermocouple to
the rear of the valve. If loose, fully tighten lightly.
• Check pilot for full ame impingement around
thermocouple. If ame is too small, check gas
pressure, adjust pilot rate screw, check pilot head for
damage or blockage.
• Check thermocouple voltage at rear of valve.
It must be greater than 7 mV. If low, replace
thermocouple.
Air in gas line (pilot
dies while knob is
depressed).
• Bleed line.
• Check gas line pressure.
• Contact dealer.
Burners will not
remain lit
Problem with
thermopile circuit.
• Check gas line pressure .
• Check for ame impingement on thermopile. If low,
see “Pilot will not remain lit”.
• Check thermopile for minimum of 200 mV 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
conguration.
• Check vent conguration with manual.
Terminal may be
recirculating ue gases.
• Check to see if terminal is on correctly.
• May need to install high wind termination cap.
• Contact dealer.
Improperly set vent
restrictor plate.
• See venting section for proper restrictor setting.
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: ames will yellow as the replace heats up.
Flames are burning
“dirty” or sooting
Flame impingement • Check log positioning.
• Check vent restrictor for proper setting.
• Increase primary air by opening venturi shutter.
• See also “Burners will not remain lit.”
