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 or replace the battery
in module.
Misaligned spark electrode. • If spark is not arcing from electrode to pilot, loosen
the screws on the pilot base adjust and tighten.
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 flame impingement around
thermocouple. If flame 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 flame impingement on thermopile. If low,
see “Pilot will not remain lit”.
• Check thermopile for minimum of 200mV 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
recirculating flue 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: flames will yellow as the fireplace heats up.
Flames are burning
“dirty” or sooting
Flame impingement • Check log positioning.
• Check vent restrictor for proper setting.
• See also “Burners will not remain lit.”
