TROUBLESHOOTING

Continued

OBSERVED PROBLEM POSSIBLE CAUSE

REMEDY

Pilot burning, no gas to burner, valve knob "ON", wall switch "ON"

1.Wall switch or wires defective

2.Thermopile may not be generating sufficient mil- livoltage.

3.Plugged burner orifice

1.Check wall switch and wires for proper connections. Jump- er wire across terminals at wall switch. If burner comes on, replace defective wall switch. If okay, jumper wires across wall switch wires at valve. If burner comes on, wires are faulty or connections are bad

2.Check thermopile with mil- livolt meter. Take reading at thermopile terminals of gas valve. It should read 325 mil- livolts minimum with optional wall switch "OFF". Replace faulty thermopile if reading is below specified minimum.

3.Check burner orifice for stop- page and remove
