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.
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.
• 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.
• Check thermocouple voltage at valve. It
must be greater than 5 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 300 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
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.
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.
• Increase primary air by opening the venturi
shutter and/or by opening the vent restrictor.
See also “Burners will not remain lit.”
Remote control doesn’t
work
Problem with the remote • One or more of the batteries are dead. See
remote control instructions.
Problem with fireplace • The on/off switch is turned to OFF.
• The gas control valve is turned to PILOT or OFF.
• The pilot has gone out.
