|
Pilot goes out when the gas knob is re- leased.
The gas valve has an interlock device which will not allow the pilot burner to be lit until the thermo- couple has cooled. Allow approximately 60 seconds for the thermocouple to cool.

Pilot will not light. | No spark at pilot burner | - | check if pilot can be lit by a match |
|
| - | check that the wire is connected to the push button ignitor. |
|
| - | check if the push button ignitor needs tightening. |
|
| - | replace the wire if the wire insulation is broken or frayed. |
|
| - | replace electrode if ceramic insulator is cracked or broken. |
|
| - | replace the push button ignitor. |
|
|
|
|
| Out of propane gas | - | fill the tank. |
| Spark gap is incorrect | - | spark gap should be 0.150" to 0.175" (5/32" to 11/64" |
|
| approx.) from the electrode tip and the pilot burner. To en- | |
|
| sure proper electrode location, tighten securing nut (finger | |
|
| tight plus 1/4 turn). | |
| No gas at the pilot burner | - | check that the manual valve is turned on. |
|
| - | check the pilot orifice for blockage. |
|
| - | replace the valve. |
