WARNING
!
WITH THE GLASS DOOR OPEN OR REMOVED.
DO NOT USE ABRASIVE CLEANERS.
PROBLEM
Pilot fl ame is not large enough
or not engulfi ng the thermopile.
Thermopile shorting.
Remote wall switch wire is too long;
too much resistance in the system.
Faulty thermostat or switch.
Refer to "MAIN BURNER GOES OUT; PILOT STAYS ON"
Vent is blocked
Vent is re-circulating
Flexible vent has become
disconnected from appliance.
System is not correctly purged
Out of propane gas.
Pilot fl ame is not large enough.
Thermocouple shorting / faulty.
Faulty valve.
Thermostat or switch is
defective
Wall switch wiring is defective.
Main burner orifi ce is plugged.
Faulty valve.
Gas piping is undersized.
Blockage in vent.
Door is ajar.
Venting action is too
great.
TEST SOLUTION
Turn up the 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 appliance.
Cap was not replaced.
-
Purge the gas line.
-
Fill the tank.
-
Turn up the pilot fl ame.
-
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.
-
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.
-
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.
Ensure the mechanical means of securing the door is
-
providing a tight seal.
Check to ensure venting is properly sealed.
-
If restriction is required see "RESTRICTING VERTICAL
-
VENT" section.
