Problem with gas valve.

• Use a DC voltmeter to measure the voltage across the

 

 

TPTH and TP terminals. Main operator voltage: Open

• If voltage is not present, check the control circuit for

 

 

proper operation.

 

 

• If proper control system voltage is present, replace the

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.

“Pilot will not remain lit”.

 

 

• Check thermopile for minimum of 300 mV when burner is

 

 

switched on.

 

 

• Check wiring to thermostat for breaks.

Leak in vent pipe

• Check for leaks in vent connections.

 

 

 

 

Improper vent configuration

• Check vent configuration with manual.

• 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.

• Increase primary air by opening the venturi shutter and/

 

 

or by opening the vent restrictor.

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.
