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.
No spark at pilot. 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.
Wire damaged to electrode.
•Replace ignitor.
Pilot will not
remain lit.
Problem with thermocouple
circuit.
• Check for proper connection of the thermocouple to the front 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 pilot orifice for debris.
• 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 and bad connections.
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
• Increase primary air by opening the venturi shutter.
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.
