SYMPTOM
Main burner goes Pilot fl ame is not large enough
out; pilot stays on. or not engulfi ng the thermo-
pile
Thermopile shorting
Remote wall switch wire is too
long; too much resistance in
the system.
Faulty thermostat or switch.
Main burner goes
Refer to "MAIN BURNER GOES OUT; PILOT STAYS ON"
out; pilot goes out.
Vent is blocked
Vent is re-circulating
4" fl exible vent has become
disconnected from fi replace.
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.
Pilot burning; no
gas to main burner;
gas knob is on 'HI';
wall switch / ther-
mostat is on.
Pilot will not light.
Out of propane gas
Spark gap is incorrect
No gas at the pilot burner

PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR OPEN
PROBLEM
S y s t e m i s n o t c o r r e c t l y
purged.
Out of propane gas.
Pilot flame is not large
enough
Pilot fl ame is not engulfi ng the
thermocouple.
Thermocouple shorting /
faulty.
Faulty valve.
Themostat or switch is de-
fective.
Wall switch wiring is defec-
tive.
M a i n b u r n e r o r i f i c e i s
plugged.
Faulty valve.
No spark at pilot burner
TEST SOLUTION
- turn up pilot fl ame.
- replace pilot assembly.
- clean thermopile connection to the valve. Reconnect.
- replace thermopile / valve.
- shorten wire to correct length or wire gauge.
- replace.
- check for vent blockage.
- check joint seals and installation.
- re-attach to fi replace.
- 7"ø cap was not replaced
- purge the gas line.
- fi ll the tank.
- turn up the pilot fl ame.
- gently twist the pilot head to improve the fl ame pattern around the
thermocouple.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace thermocouple.
- replace valve.
- replace.
- connect a jumper wire across the wall switch terminals; if main burner
lights, replace switch / 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.
- remove stoppage in orifi ce.
- replace.
- 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.
- fi ll 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 loca-
tion, tighten securing nut (fi nger tight plus 1/4 turn).
- check that the manual valve is turned on.
- check the pilot orifi ce for blockage.
- replace the valve.
- call the gas distributor.
