K. Frequently Asked Questions
ISSUE
SOLUTIONS
This is a result of gas combustion and temperature variations. As the fireplace warms, this
condensation will disappear.
Condensation on the glass
This is a result of normal operation and the flames will begin to yellow as the fireplace is al-
lowed to burn for 20 to 40 minutes.
Blue flames
When first operated, this fireplace may release an odor for the first several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from finish-
ing materials and adhesives used near the fireplace. These circumstances may require ad-
ditional curing related to the installation environment.
Odor from fireplace
This is a normal result of the curing process of the paint and logs. Glass should be cleaned
within 3 to 4 hours of initial burning. A non-abrasive cleaner such as gas appliance glass
cleaner may be necessary. See your dealer.
Film on the glass
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
the sound produced by a furnace or heating duct. This noise does not affect the operation or
longevity of the fireplace.

Troubleshooting
12
With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do
experience a problem, this troubleshooting guide will assist a qualified service technician in the diagnosis of a problem and
the corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician. Contact
your dealer to arrange a service call by a qualified service technician.
A. Intellifire Ignition System
Symptom
Possible Cause
Corrective Action
1. Pilot won’t light.
The ignitor/module
makes noise, but no
spark.
A. Incorrect wiring.
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are
connected to correct terminals on module and pilot assembly.
B. Loose connections or electrical
shorts in the wiring.
Verify no loose connections or electrical shorts in wiring from mod-
ule to pilot assembly. Verify connections underneath pilot assem-
bly are tight; also verify connections are not grounding out to metal
chassis, pilot burner, pilot enclosure, mesh screen if present, or any
other metal object.
C. Ignitor gap is too large.
D. Module.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place a grounded wire about 3/16 in. (5
mm) away from “I” terminal on module. Place ON/OFF rocker switch
or wall switch in ON position. If there is no spark at “I” terminal module
must be replaced. If there is a spark at “I” terminal, module is fine.
Inspect pilot assembly for shorted sparker wire or cracked insulator
around electrode. Replace pilot if necessary.
2. Pilot won’t light,
there is no noise or
spark.
A. No power or transformer installed
incorrectly.
Verify that transformer is installed and plugged into module. Check
voltage of transformer under load at spade connection on module
with ON/OFF switch in ON position. Acceptable readings of a good
transformer are between 3.2 and 2.8 volts AC.
B. A shorted or loose connection in
wiring configuration or wiring har-
ness.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fit. Verify pilot assembly wiring to module. Re-
move and verify continuity of each wire in wiring harness. Replace
any damaged components.
C. Improper wall switch wiring.
D. Module not grounded.
Verify that 110/VAC power is “ON” to junction box.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
E. Module.
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place ON/OFF rocker switch or wall
switch in ON position. If there is no spark at “I” terminal module
must be replaced. If there is a spark at “I” terminal, module is fine.
Inspect pilot assembly for shorted sparker wire or cracked insulator
around electrode.
3. Pilot sparks, but
Pilot will not light.
A. Gas supply.
Verify that incoming gas line ball valve is “open”. Verify that inlet
pressure reading is within acceptable limits, inlet pressure must not
exceed 14 in. W.C.
B. Ignitor gap is too large.
C. Module is not grounded.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
Verify module is securely grounded to metal chassis of appliance.
D. Module voltage output / Valve/Pilot Verify battery voltage is at least 2.7 volts. Replace batteries if volt-
solenoid ohms readings. age is below 2.7.

gulfing flame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. Verify cor-
rect pilot orifice is installed and gas inlet is set to pressure
specifications. Clean flame sensing rod with emery cloth to
remove any contaminants that may have accumulated on
flame sensing rod.
C. Module is not grounded.
Verify module is securely grounded to metal chassis of ap-
pliance. Verify that wire harness is firmly connected to the
module.
D. Damaged pilot assembly or contami-
Verify that ceramic insulator around the flame sensing rod
is not cracked, damaged, or loose. Verify connection from
flame sensing rod to white sensor wire. Clean flame sensing
rod with emery cloth to remove any contaminants that may
have accumulated on flame sensing rod. Verify continuity
with a multimeter with ohms set at lowest range. Replace
pilot if any damage is detected.
nated flame sensing rod.
E. Module.
Turn ON/OFF rocker switch or wall switch to OFF position.
Remove ignitor wire “I” from module. Place ON/OFF rocker
switch or wall switch in ON position. If there is no spark at “I”
terminal module must be replaced. If there is a spark at “I”
terminal, module is fine.
