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 pressure
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 the elec-
trode 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 recommended.
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 fireplace. Usually
there is a valve near the fire-
place and sometimes there is a
valve near the main. There can
be more than one (1) valve be-
tween the fireplace and main
B) Low pressure can be caused
by a variety of situations such
as bent line, or gas supplier
4. Check propane/LP supply
and contact local propane/LP
supplier
1. This is common with most
fireplaces. If noise is exces-
sive, contact qualified service
person
