Trouble Shooting

The  main  burner 

does  not  ignite 

when called for.

The gas valve may not be on.

• Check that the gas control knob is in the “ON” position.

Thermostat is not calling for 

heat.

• Adjust the thermostat several degrees above ambient temperature.

Problem with gas valve.

• Use a DC voltmeter to measure the voltage across the TPTH and 

TP terminals. Main operator voltage: Open circuit ≥ 325mV Closed 

circuit ≥ 100mV

• If voltage is not present, check the control circuit for proper 

operation.

• If proper control system voltage is present, replace the gas control.

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.

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 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.

Insufficient air 

for combustion

• Air tight house.

•  A  vacuum  in  room  due  to 

other air-moving device.

• Supply make up air to the unit.
