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.

Symptom Possible Cau se Corrective Action
1. After repeated
triggering of the red
or black piezo button,
the spark ignitor will
not light the pilot.
a. Defective ignitor. Check the spark at the electrode and pilot. If no spark and electrode wire is
properly connected, replace the ignitor.
b. Defective pilot or
misaligned electrode
(spark at electrode).
Using match, light the pi lot. If the pilot lights, turn off the pi lo t a nd trigger the red o r
black piezo button again. If the pilot lights, an improper gas/air mixture caused the
bad lighting and a longer purge period is recommended. If the pilot will not light,
ensure the the gap at the electrode and pilot is one-eighth (1/8) inch to have a
strong spark. If the gap is OK, replace the pilot.
c. No gas or low gas
pressure. Check the remote shut-off valvess from the fireplace. Usually, there is a valve near
the gas main. There can be more than one (1) valve between the fireplace and the
main.
d. No LP in tank. Check the LP (propane) tank. You may be out of fuel.
2. The pilot will not
stay lit after ca re fully
following the lighting
instructions.
a. Defective
thermocouple. Check that the pilot flame impinges on the thermocouple. Clean and/or adjust the
pilot for maximum flame impingement.
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
copper lead. Start the pilot and hold the valve knob in. If the millivolt reading is less
than 15mV, replace the thermocouple.
b. Defective va lve. If the thermocouple is produci ng more than 15 milli volts , re place faulty valve.
3. The pilot is
burning, there is no
gas burner, the valve
knob is in the ON
position, and the
ON/OFF switch is in
the ON position.
a. ON/OFF switch or
wires defective. Check the ON/OFF switch and wires for proper connections. Place the jumper
wires across the terminals at the switch. If the burner comes on, replace the
defective switch. If the switch is OK, place the jumper wires across the switch wires
at the gas valve. If the burner comes on, the wires are faulty or connections are
bad.
b. Thermopile may
not be g e nerating
sufficient mi lli voltage.
If the pilot flame is not close enough physically to the thermopile, adjust the pilot
flame.
Be sure the wire connections from the thermopile at the gas valve terminals are
tight and that the thermopi le is fully inserted i nto the pilot brack e t.
Check the thermop i le with a millvolt meter. Take the readi ng at TH-TP&TP
terminals of the gas valve. The meter should read 325 millivolts minimum, while
holding the valve knob depressed in the pilot position, with the pilot lit, and the
ON/OFF switch i n the OF F position. Rep lace the faulty thermopile i f the reading is
below the specified mi nimum.
With the pilot in the ON p osition, di s c o nnect the thermopile le a d s 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 va lve. Turn the valve knob to the ON po s ition. Place the ON/O F F switch in the ON
position. C he c k the mi llivolt meter a the thermo p ile terminals. The mi llivolt meter
should read greater than 125mV. If the reading is acceptable, and if the burner
does not come on, replace the gas valve.
d. Plugged burner
orifice. Check the burner orifice for stoppage. Remove stoppage.
e. Wall switch or
wires are defective. Follow the corrective action in Symptom and Possible Cause 1.a above. Check
the switch and wiring. Replace where defective.
