|
| lights, an improper gas/air mixture caused |
|
| the bad lighting and a longer purge period |
|
| is recommended. If the pilot will not light, |
|
| ensure that the gap at the electrode and |
|
| pilot is 0.3 cm to have a strong spark. If the |
|
| gap is OK, replace the pilot. |
| c. No gas or low gas | Check the remote |

|
| gas main. There can be more than one (1) |
|
| valve between the fireplace and the main. |
| d. No LP in the tank | Check the LP (propane) tank. You may be |

| out of fuel. |
2. The pilot will | a. Defective thermocouple | Check that the pilot flame impinges on the |

|
| Disconnect the thermocouple from the |
|
| valve, place one millivolt meter lead wire |
|
| on the tip of the thermocouple 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 thermocouple is producing more than 15 |
|
| millivolts, replace faulty valve. |
