3. (Continued) | C. Valve. | Turn the valve knob to the ON position. Place the ON/ | |
|
| OFF switch in the ON position. Take a reading with a | |
|
| millivolt meter at the thermopile terminals. The millivolt | |
|
| meter should read greater than 125mV. If the reading | |
|
| is acceptable, and if the burner does not come on, re- | |
|
| place the gas valve. | |
|
|
| |
| D. Plugged burner orifice. | Check the burner orifice for stoppage. Remove stop- | |
|
| page. | |
|
|
| |
| E. Wall switch or wires. | Check the wall switch and wires for proper connec- | |
|
| tions. Place the jumper wires across the terminals at | |
|
| the wall switch. If the burner comes on, replace the | |
|
| wall switch. If the wall switch is OK, place the jumper | |
|
| wires across the wall switch wires at the gas valve. If | |
|
| the burner comes on, the wires are faulty or connec- | |
|
| tions are bad. | |

6. Glass soots. | A. Flame impingement. | Adjust the log set so that the flame does not exces- | |
|
| sively impinge on it. Refer to log instructions. | |
|
|
| |
| B. Improper air shutter setting. | Refer to manual for shutter set points. Ensure that set | |
|
| point is correct for appliance/gas type. If unit has ad- | |
|
| justable shutter, it may be necessary to increase shut- | |
|

|
|
| |
| C. Debris around air shutter. | Inspect the opening at the base of the burner. NO MA- | |
|
| TERIAL SHOULD BE PLACED IN THIS OPENING. | |

|
| Ensure that no debris has been placed at the base of, | |
|
| or in the area of the air holes in the center of the base | |
|
| pan beneath the burner. | |
|
| Ensure that the glass is tightened properly on the unit, | |
|
| particularly on top corners. | |
