- purge the gas line with the glass door open.
- fill the tank.
- turn up the pilot flame.
- gently twist the pilot head to improve the flame pattern around the thermocouple.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection. - replace thermocouple.
- replace.
- connect a jumper wire across the wall switch terminals; if main burner lights, replace switch / thermostat.
- disconnect switch wires & connect a jumper wire across terminals 1 & 3; if the main burner lights, check the wires for defects and / or replace wires.
- remove stoppage in orifice. - replace.
- Vent has become blocked or disconnected. Correct. See Figure 2.
- Unit has overheated. See Figure 2
- 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.
- fill 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 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.W415-0377 / C / 09.23.05
TEST SOLUTION
- turn up pilot flame.
- replace pilot assembly.
- clean thermopile connection to the valve. Reconnect. - replace thermopile / valve.
- shorten wire to correct length or wire gauge.
- replace.
- Vent has become blocked or disconnected. Correct. See Figure 2. - Unit has overheated. See Figure 2

TROUBLE SHOOTING GUIDE
BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR REMOVED.
SYMPTOM PROBLEM
Main burner goes out; pilot stays on.
Main burner goes out; pilot goes out.
Pilot goes out when the gas knob is re- leased.
The gas valve has an interlock de- vice which will not allow the pilot burner to be lit until the thermo-
couple has cooled. Allow ap- proximately 60 seconds for the thermocouple to cool.
Pilot burning; no gas to main burner; gas knob is on 'HI'; wall switch / ther- mostat is on.
Pilot will not light.
Pilot flame is not large enough or not engulfing the thermopile
Thermopile shorting
Remote wall switch wire is too long; too much resist- ance in the system.
Faulty thermostat or switch.
Vent safety switch has opened. (Tripped)
Hi Limit switch has opened. (Tripped)
Refer to "MAIN BURNER GOES OUT; PILOT STAYS ON"
Faulty thermocouple. - replace.
System is not correctly purged.
Out of propane gas.
Pilot flame is not large enough
Pilot flame is not engulfing the thermocouple. Thermocouple shorting / faulty.
Faulty valve.
Themostat or switch is de- fective.
Wall switch wiring is defec- tive.
Main burner orifice is plugged. Faulty valve.
Vent safety switch has opened. (Tripped)
Hi Limit switch has opened.
(Tripped)
No spark at pilot burner
Out of propane gas Spark gap is incorrect
No gas at the pilot burner
