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 correct 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 appliance.
- Re-attach to appliance.
- Cap was not replaced.
Pilot goes out when the gas
knob is released.
If equipped, 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.
Thermocouple shorting / faulty. - Loosen and tighten thermocouple.
- Clean thermocouple and valve connection.
- Replace thermocouple.

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 goes out while
standing; Main burner is in
‘OFF’ position.
Gas piping is undersized. - Turn on all gas appliances and see if pilot fl ame fl utters,
diminishes or extinguishes, especially when main burner
ignites. Monitor appliance supply working pressure.
- Check if supply piping size is to code. Correct all undersized piping.
Main burner fl ame is a blue,
lazy, transparent fl ame.
Blockage in vent. - Remove blockage. In really cold conditions, ice buildup may
occur on the terminal and should be removed as required.
To minimize this from happening again, it is recommended
that the vent lengths that pass through unheated spaces
(attics, garages, crawl spaces) be wrapped with an insulated
mylar sleeve. Prevent sleeve from sagging. Contact your
local authorized dealer for more information.
Flames are very aggressive. Door is ajar. - Ensure the mechanical means of securing the door is
providing a tight seal.
Venting action is too
great.
- Check to ensure venting is properly sealed.
- If restriction is required see “RESTRICTING VERTICAL
VENT” section.
