- fill 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
location, tighten securing nut (finger tight plus 1/4 turn).
No gas at the pilot burner
- check that the manual valve is turned on.
- check the pilot orifice for blockage.
- replace the valve.
- call the gas distributor.
Main burner goes
out; pilot stays on. Pilot flame is not large
enough or not engulfing the
thermopile - turn up pilot flame.
- replace pilot assembly.
Thermopile shorting - clean thermopile connection to the valve. Reconnect.
- replace thermopile / valve.
Remote wall switch wire is
too long; too much resis-
tance 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
Vent is re-circulating
- check for vent blockage.
- check joint seals and installation.
4" flexible vent has become
disconnected from fireplace.
- re-attach to fireplace.
Remote wall
switch is in "OFF"
position; main
burner comes on
when gas knob is
turned to "ON" po-
sition. Wall switch is mounted up-
side down
- reverse.
Faulty valve.
- replace.
- replace. Remote wall switch is
grounding.
- check for ground (short); repair ground or replace wire. Remote wall switch wire is
grounding.
Flames are con-
sistently too large
or too small.
Carboning occurs. - 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
OVERTORQUE.
Leak test with a soap and water solution. Unit is over-fired or under-
fired.
