Main burner goes
out; pilot goes out.
Main burner goes
out; pilot stays on.
Pilot fl ame is not large enough
or not engulfi ng the thermo-
pile
- turn up pilot fl ame.
- replace pilot assembly.
Thermopile shorting
- clean thermopile connection to the valve. Reconnect.
- test and replace thermopile if required.
Temperature setting on trans-
mitter is satisfi ed
- turn up temperature setting.
Pilot goes out while
s t a n d i n g ; M a i n
burner is in ‘OFF’
position.
Pilot burning; no
gas to main burner;
Flame height is on
‘HI’; Remote and
transmitter ON
Remote receiver
- disconnect switch wires &connect a jumper wire across terminals
1 & 3; if the main burner lights, check the wires for defects and / or
replace wires.
M a i n b u r n e r o r i f i c e i s
plugged.
- remove stoppage in orifi ce.
Faulty thermopile.
- test and replace if required.
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.
Refer to “MAIN BURNER GOES OUT; PILOT STAYS ON”
Vent is blocked
Vent is re-circulating
- check for vent blockage.
- check joint seals and installation.
8” fl exible vent has become
disconnected from fi replace.
- re-attach to fi replace.
Pilot will not light.
- check if pilot can be lit by a match
- check that the wire is connected to the spark module.
- check batteries.
- replace the wire if the wire insulation is broken or frayed.
- replace the electrode if the ceramic insulator is cracked or broken.
- replace spark module.
No spark at pilot burner
- fi ll the tank.
Out of propane gas
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 loca-
tion, 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.
- call the gas distributor.

BURNER
THERMOCOUPLE
THERMOPILE
Flames are consis-
tently too large or
too small. Carbon-
ing occurs.
Unit is over-fi red or under-
fi red.
- check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock-wise
2 or 3 turns and then placing pressure gauge tubing over the test point.
Gauge should read 7” (minimum 4.5”) water column for natural gas or
13” (11” minimum) water column for propane. Check that main burner
is operating on “HI”.
Outlet pressure can be checked the same as above using screw (B).
Gauge should read 3.5” water column for natural gas or 10” water column
for propane. Check that main burner is operating on “HI”.
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN
SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVER-
TORQUE.
Leak test with a soap and water solution.
