PROBLEM
- 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.
- 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 location, tighten securing nut (finger tight plus 1/4
turn).
- check that the manual valve is turned on.
- check the pilot orifice for blockage.
- replace the valve.
- call the gas distributor.
- fill the tank.
- fill the tank.
- turn up the pilot flame.
- turn up pilot flame.
- replace pilot assembly.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace thermocouple.
- replace valve.
- replace.
- replace.
- remove stoppage in orifice.
- replace.
- connect a jumper wire across the wall switch terminals; if
main burner lights, replace 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.
- turn on all gas appliances and see if pilot flame flutters,
diminishes or extinguishes, especially when main burner ig-
nites. Monitor supply pressure.
- check if supply piping size is to code. Correct all undersized
piping.
- turn up pilot flame.
- replace pilot assembly.
- clean thermopile and thermopile connection to valve.
- shorten wire to correct length or wire gauge.
- replace
