Trouble Shooting
Problem
Possible Cause
Solution
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.
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.
