PROBLEM
- turn up pilot fl ame.
- replace pilot assembly.
- clean thermopile connection to the valve. Reconnect.
- replace thermopile / valve.
- shorten wire to correct length or wire gauge.
- replace.
- purge the gas line.
- fi ll the tank.
- turn up the pilot fl ame.
- gently twist the pilot head to improve the fl ame pattern around the
thermocouple.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace thermocouple.
- replace valve.
- replace.
- connect a jumper wire across the wall switch terminals; if main burner
lights, replace switch / thermostat.
- disconnect the switch wires & connect a jumper wire across terminals
1 & 3; if the main burner lights, check the wires for defects and / or
replace wires.
- replace.
- 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 the electrode if the ceramic insulator is cracked or broken.
- replace the push button ignitor.
- fi ll the tank.
- spark gap should be 0.150" to 0.175" (5/32" to 11/64" approx.) from
the electrode tip and the pilot burner. To ensure proper electrode loca-
tion, tighten securing nut (fi nger tight plus 1/4 turn).
- check that the manual valve is turned on.
- check the pilot orifi ce for blockage.
- replace the valve.
- call the gas distributor.
