TROUBLESHOOTING
NOTE:
Before troubleshooting the system, make sure the gas shutoff valve is ON. The two most common causes of a malfunctioning gas
appliance are:
1. Loose wiring connections
2. Construction debris clogging pilot and/or gas control valve filter
OBSERVED PROBLEM
POSSIBLE CAUSE
REMEDY
Pilot will not light
1. No gas supply or shutoff valve is OFF
2. Air in gas line
3. Construction debris clogging pilot orifice
4. Low gas pressure
5. Control valve knob is not on the PILOT position
6. Kinked pilot line
7. Bad valve
8. Vent damper not fully open
1. Check to see if you have gas supply
2. Hold regulator control valve in the PILOT
position for 2 to 3 minutes to purge air.
If you smell gas stop and wait for a few
minutes before trying to light fireplace
3. Remove debris and dirt, inspect and clean
any other possible obstructions
4. Contact your gas supplier
5. Refer to section on pilot lighting
6. Have a qualified technician replace pilot line
7. Replace regulator valve
(see Accessories,
Page 27
)
8. Open vent damper until fully locked in OPEN
position
Pilot will not stay lit
1. Loose wiring on thermopile to regulator valve. No
millivolt current is being sent back to regulator
2. If valve knob and wall switch are in the ON posi-
tion, probable defective regulator valve
3. Vent damper not fully open
1. Check wiring connections. Refer to wiring
diagram shown in Wall Switch Installation,
Page 11
2. Have a qualified technician replace valve
3. Open vent damper until fully locked in OPEN
position
No gas to burner, although wall switch and valve are
set to the ON position
1. Wall switch wires defective or too long
2. Thermopile not generating sufficient voltage
1. Check electrical connections
2. See Pilot will not stay lit, above
Frequent pilot outage
1. Pilot flame may be too low, causing safety pilot
to “drop out”
2. Improper venting or excessive blockage
1. Clean and adjust pilot flame for maximum
flame impingement on thermopile
2. Have vent system inspected, including
termination cap. Remove any restriction
or obstruction
Pilot goes out when wall switch is ON
1. Millivolt output on thermopile too high
1. Replace thermopile
Spark igniter will not light pilot after repeated trig-
gering of red button
1. Defective igniter (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. Check for spark at electrode and pilot. If
no spark and electrode wire is properly
connected, replace igniter
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
fireplace and sometimes there is a valve
near the main. There can be more than one
valve between fireplace and main
B) Low pressure can be caused by a variety
of situations such as bent line, or gas sup-
plier
4. Check propane/LP supply and contact local
propane/LP supplier
Fireplace produces a clicking/ticking noise just after
burner is lit or shut off
1. Metal expanding while heating or contracting
while cooling
1. This is normal with most fireplaces. If
noise is excessive, contact qualified service
person
