SYMPTOM PROBLEM TEST SOLUTION
Main burner goes
out; pilot stays on.
Pilot fl ame is not large
enough or not engulfi ng
the thermopile.
- Turn up the pilot fl ame.
- 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 connect length or wire gauge.
Faulty thermostat or
switch.
- Replace.
Main burner goes
out; pilot goes
out.
Refer to “MAIN BURNER
GOES OUT; PILOT
STAYS ON”
Vent is blocked
- Check for vent blockage.
Vent is re-circulating - Check joint seals and installation
Flexible vent has become
disconnected from fi replace.
- Re-attach to fi replace.
- Cap was not replaced.
Pilot goes out
when the gas
knob is released.
The gas valve
has an interlock
device which
will not allow
the pilot burner
to be lit until the
thermocouple
has cooled. Allow
approximately 60
seconds for the
thermocouple to
cool.
System is not correctly
purged.
- Purge the gas line.
Out of propane gas. - Fill the tank.
Pilot fl ame is not large
enough.
- Turn up the pilot fl ame.
Pilot fl ame is not engulfi ng
the thermocouple
- Gently twist the pilot head to improve the fl ame
pattern around the thermocouple.
Thermocouple shorting /
faulty.
- Loosen and tighten thermocouple.
- Clean thermocouple and valve connection.
- Replace thermocouple.
- Replace valve.
Faulty valve. - Replace.
Pilot burning;
no gas to main
burner; gas
knob is on ‘HI’;
wall switch /
thermostat is on.
Thermostat 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 orifi ce is plugged. - Remove stoppage in orifi ce.
Faulty valve. - Replace.
Pilot will not light. No spark at pilot burner. - Check if pilot can be lit by a match.
- Check that the wire is connected to the push button igniter.
- Check if the push button igniter 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
Out of propane gas. - Fill the tank.
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 ensure proper
electrode location, tighten securing nut (fi nger tight plus 1/4 turn).
No gas at the pilot burner. - Check that the manual valve is turned on.
- Check the pilot orifi ce for blockage.
- Replace the valve.
- Call the gas distributor.
