Trouble Shooting
Problem Possible Cause Solution
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 there is 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
away from burner and retighten.
Pilot will not remain lit Problem with thermocouple
circuit.
• Check for proper connection of the thermocouple to
the rear of the valve. If loose, tighten lightly.
• 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 or blockage.
• Check thermocouple voltage at rear of 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 200 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 the 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.
• See also “Burners will not remain lit.”
Flame goes out / comes
on frequently during a
short period of time.
Defective rocker switch. • Check rocker switch connections.
• Replace switch if necessary.
