thermocouple
Thermocouple shorting / faulty.
Faulty valve.
Thermostat or switch is
defective
Wall switch wiring is defective.

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.
- 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.
- 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.
