Main burner goes
out; pilot stays on.
Pilot fl ame is not large enough
or not engulfi ng the thermo-
pile
- service or replace Oxygen Depletion Sensor System
- correct piping and/or regulator to provide correct pressure
Thermopile shorting
- clean thermopile connection to the valve. Reconnect.
- replace Oxygen Depletion Sensor System / 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.
Pilot burning; no
gas to main burner;
gas knob is on ‘HI’;
wall switch / ther-
mostat is on.
Themostat or switch is de-

- connect a jumper wire across the wall switch terminals; if main burner
lights, replace switch / thermostat.
M a i n b u r n e r o r i f i c e i s - remove stoppage in orifi ce.
Faulty valve.
- replace.
Wall switch wiring is defec-
tive.
- disconnect wires from valve. Connect a jumper wire across terminals
1 & 3; if the main burner lights, check the wires for defects and / or
replace wires.
Pilot goes out when
the gas knob is re-
leased.
The gas valve has
an interlock device
which will not al-
low the pilot burn-
er to be lit until
the thermocouple
has cooled. Allow
approximately 60
seconds for the
thermocouple to
cool.

- purge the gas line.
Thermocouple shorting /
faulty.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace Oxygen Depletion Sensor System
- test and replace valve.

No spark at pilot burner
- fi ll the tank.
Out of propane gas
No gas at the pilot burner
- check that the manual valve is turned on.
- check the pilot orifi ce for blockage.
- replace the valve / Oxygen Depletion Sensor System.
- call the gas distributor.
