5 Troubleshooting

With proper installation, operation, and maintenance your gas fireplace will

provide years of trouble-free service. If you do experience a problem, this

troubleshooting guide will assist a qualified service person in the diagnosis

of a problem and the corrective action to be taken. This troubleshooting

guide can only be used by a qualified service technician.

Ensure that the thermocouple connection at the gas valve is fully inserted and tight

 

 

 

 

(hand tighten plus 1/4 turn).

 

 

 

 

Disconnect the thermocouple from the valve, place one millivolt meter lead wire on

 

 

 

 

the tip of the thermcouple and the other meter lead wire on the thermocouple

than 15mV, replace the thermocouple.

 

 

b. Defective valve.

 

If the thermocouple is producing more than 15 millivolts, replace faulty valve.

Be sure the wire connections from the thermopile at the gas valve terminals are

 

 

 

 

 

 

 

 

tight and that the thermopile is fully inserted into the pilot bracket.

 

 

 

 

Check the thermopile with a millvolt meter. Take the reading at TH-TP&TP

 

 

 

 

terminals of the gas valve. The meter should read 325 millivolts minimum, while

below the specified minimum.

 

 

 

 

With the pilot in the ON position, disconnect the thermopile leads from the valve.

 

 

 

 

Take a reading at the thermopile leads. The reading should be 325 millivolts

 

 

 

 

minimum. Replace the thermopile if the reading is below the minimum.

 

 

c. Defective valve.

 

Turn the valve knob to the ON position. Place the ON/OFF switch in the ON

 

 

 

 

position. Check the millivolt meter a the thermopile terminals. The millivolt meter

 

 

 

 

should read greater than 125mV. If the reading is acceptable, and if the burner

 

 

 

 

does not come on, replace the gas valve.
