TROUBLESHOOTING
Continued
OBSERVED PROBLEM
Pilot goes out when wall switch
is ON
Spark ignitor will not light pilot
after repeated triggering of
red button
Fireplace produces a clicking/
ticking noise just after burner
is lit or shut off
POSSIBLE CAUSE
1. Millivolt output on thermo-
pile too high
1. Defective ignitor (no spark
at electrode)
2. Defective pilot or misaligned
electrode at pilot (spark at
electrode)
3. No gas or low gas pres-
sure
4. If using propane/LP gas, no
propane/LP gas in tank
1. Metal expanding while
heating or contracting while
cooling
REMEDY
1. Replace thermopile
1. Check for spark at electrode
and pilot. If no spark and
electrode wire is properly
connected, replace ignitor
2. Using a match, light pilot. If
pilot lights, turn off pilot and
trigger the red button again.
If pilot lights, an improper
gas/air mixture caused the
improper lighting and a
longer purge period is rec-
ommended. If pilot will not
light, check gap at electrode
and pilot. Gap should be
1/8" to have a strong spark.
If okay, replace pilot
3. A) Check remote shut off
valves from replace. Usu-
ally there is a valve near the
fireplace and sometimes
there is a valve near the
main. There can be more
than one valve between
replace and main
B) Low pressure can be
caused by a variety of situ-
ations such as bent line, or
gas supplier
4. Check propane/LP supply
and contact local propane/
LP supplier
1. This is normal with most
replaces. If noise is ex-
cessive, contact qualied
service person
