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 ame impingement around
thermocouple. If ame 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 ame 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 conguration • Check vent conguration with manual.
Terminal may be recirculating
ue 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: ames will yellow as the replace 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 replace • The on/off switch is turned to OFF.
• The gas control valve is turned to PILOT or OFF.
• The pilot has gone out.
