Troubleshooting

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, adjust 

by loosening 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 5mV.  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 in thermopile. If low, 

see “Pilot will not remain lit”.

• Check thermopile for minimum of 300mV 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 stay 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.
