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.
System is not correctly purged. - purge the gas line with the glass door open.
Out of propane gas. - fill the tank.
Pilot flame is not large enough - turn up the pilot flame.
- gently twist the pilot head to improve the flame pattern
around the thermocouple. Pilot flame is not engulfing the
thermocouple.
Thermocouple shorting / faulty. - loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace thermocouple.
- replace valve.
Faulty valve. - replace.
Pilot will not light. - 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. No spark at pilot burner
- fill the tank. Out of propane gas
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.
- call the gas distributor.
Pilot burning; no gas
to main burner; gas
knob is on 'HI'; wall
switch / thermostat is
on. Themostat or switch is defective. - connect a jumper wire across the wall switch terminals; if
main burner lights, replace switch / thermostat.
Wall switch wiring is defective. - 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.
Main burner orifice is plugged. - remove stoppage in orifice.
Faulty valve. - replace.
Pilot goes out while
standing; Main burner
is in 'OFF' position. Gas piping is undersized. - turn on all gas appliances and see if pilot flame flutters,
diminishes or extinguishes, especially when main burner
ignites. Monitor appliance supply working pressure.
- check if supply piping size is to code. Correct all under-
sized piping.
Main burner goes out;
pilot stays on. Pilot flame is not large enough or
not engulfing the thermopile - turn up pilot flame.
- replace pilot assembly.
Thermopile shorting - clean thermopile connection to the valve. Reconnect.
- replace thermopile / valve.
Remote wall switch wire is too
long; too much resistance in the
system. - shorten wire to correct length or wire gauge.
Faulty thermostat or switch. - replace.
