14 Troubleshooting

With proper installation, operation, and maintenance your gas appliance 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.

A. Standing Pilot Ignition System

Symptom

Possible Causes

Corrective Action

 

 

 

1. After repeated triggering

a. Defective ignitor.

Check the spark at the electrode and pilot. If no spark and electrode

of the red or black piezo

 

wire is properly connected, replace the ignitor.

ignitor button, the spark

 

 

b. Defective pilot or misaligned

Using match, light the pilot. If the pilot lights, turn off the pilot and

ignitor will not light the pilot.

 

electrode (spark at electrode).

trigger the red piezo ignitor button again. If the pilot lights, an im-

 

 

proper gas/air mixture caused the bad lighting and a longer purge

 

 

period is recommended. If the pilot will not light, ensure 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 valves 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

a. Defective thermocouple.

Check that the pilot flame impinges on the thermocouple. Clean

after carefully following the

 

and/or adjust the pilot for maximum flame impingement.

lighting instructions.

 

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 valve.

If the thermocouple is producing more than 15 millivolts, replace

 

 

faulty valve.

 

 

 

3. The pilot is burning,

a. ON/OFF switch or wires

Check the ON/OFF switch and wires for proper connections. Place

there is no burner flame,

defective.

the jumper wires across the terminals at the switch. If the burner

the valve knob is in the ON

 

comes on, replace the defective switch. If the switch is OK, place the

position, and the ON/OFF

 

jumper wires across the switch wires at the gas valve. If the burner

switch is in the ON position.

 

comes on, the wires are faulty or connections are bad.

 

 

 

 

b. Thermopile may not be gener-

If the pilot flame is not close enough physically to the thermopile,

 

ating sufficient millivoltage.

adjust the pilot flame.

 

 

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 millivolt meter. Take the reading 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 in the OFF

 

 

position. Replace the faulty thermopile if the reading is 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 read-

 

 

ing should be 325 millivolts minimum. Replace the thermopile if the

 

 

reading is below the minimum.
