Main burner goes
out; pilot stays on.
Pilot flame is not large
enough or not engulfing the
thermopile
- 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 resist-
ance 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 / thermostat
is on.
Themostat or switch is de-
fective.
- connect a jumper wire across the wall switch terminals; if main
burner lights, replace switch / thermostat.
Main burner orifice is plugged. - remove stoppage in orifice.
Faulty valve.
- replace.
Wall switch wiring is defec-
tive.
- disconnect wires from valve. Connect a jumper wire across termi-
nals 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 allow
the pilot burner to
be lit until the ther-
mocouple has
cooled. Allow ap-
proximately 60
seconds for the
thermocouple to
cool.
System is not correctly
purged.
- purge the gas line. If a glass door has been installed, ensure that
the door is open or removed prior to purging.
Thermocouple shorting /
faulty.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace Oxygen Depletion Sensor System
- test and replace valve.
Faulty valve.
- replace.
Out of propane gas. - fill the tank.
Pilot flame is not large
enough. (Supply pressure
too low.)
- service or replace Oxygen Depletion Sensor System

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 the electrode if the ceramic insulator is cracked or broken.
- replace the push button ignitor.
No spark at pilot burner
- fill the tank.Out of propane gas
No gas at the pilot burner
- check that the manual valve is turned on.
- check the pilot orifice for blockage.
- replace the valve / Oxygen Depletion Sensor System.
- call the gas distributor.
