13 Troubleshooting
With proper installation, operation, and maintenance your gas appliance will provide years of
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 | |
|
| spark. If the gap is OK, replace the pilot. | |
|
|
| |
| c. No gas or low gas pressure. | Check the remote | |
|
| 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 | |
|
| ||
|
| 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. | |
