Spark will not light the

Defective piezo ignitor

 

• Check connections to 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 and

 

 

 

 

 

 

 

tighten.

 

 

 

Pilot will not remain lit

Problem with thermocouple

• Check for proper connection of the thermocouple to

 

 

 

 

circuit

 

 

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 5mV. If low, replace thermocouple.

 

 

 

 

 

 

 

 

 

 

Air in gas line (pilot dies

• Check for flame impingement in thermopile. If low,

 

 

 

 

 

 

 

see “Pilot will not remain lit”.

 

 

 

 

 

 

 

• Check thermopile for minimum of 300mV 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.

• Check to see if terminal is on correctly.

 

 

 

 

recirculating flue gases

 

• 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”

Flame impingement

 

• Check log positioning.

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.
