K. Frequently Asked Questions
ISSUE
SOLUTIONS
Condensation on the glass
This is a result of gas combustion and temperature variations. As the fireplace warms, this
condensation will disappear.
Blue flames
This is a result of normal operation and the flames will begin to yellow as the fireplace is allowed to burn for 20 to 40 minutes.
Odor from fireplace
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
finishing materials and adhesives used near the fireplace. These circumstances may require
additional curing related to the installation environment.
Film on the glass
Metallic noise
10
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.
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.

Heatilator • GBST4336I, GBFL4136I • 2135-900 • 2/08
E. Negative Pressure
WARNING! Asphyxiation Risk! Negative pressure can
cause spillage of combustion fumes and soot. Fireplace
needs to draft properly for safety.
Draft is the pressure difference needed to vent fireplaces
successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of fireplace and chimney
Negative pressure results from the imbalance of air
available for the fireplace to operate properly. Causes for
this imbalance include:
• Ensure adequate outdoor air is supplied for combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fireplace.
• Avoid installing the fireplace near doors, walkways or
small isolated spaces.
• Recessed lighting should be of “sealed can” design; attic
hatches weather stripped or sealed; and attic mounted
ductwork and air handler joints and seams taped or
sealed.
• Range hoods
• Basement installations should be avoided due to stack
effect. Stack effect creates negative pressure in lower
levels. Hearth & Home Technologies recommends the
use of direct vent fireplaces in basements.
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
Location of the fireplace and chimney will affect performance. As shown in Figure 4.2, the chimney should:
• Clothes dryers
• Be installed through the warm space enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fire.
• Exhaust fans (kitchen, bath, etc.)
• Location of return-air to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks)
To minimize the effects of negative air pressure, the following must be considered:
• Install the fresh air kit. Install the intake on the side of
the house towards prevailing winds during the heating
season.
Recommended
Location
• Penetrate the highest part of the roof. This minimizes the
effects of wind turbulence.
• Be located away from trees, adjacent structures, uneven
roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized.
Consider the fireplace location relative to floor and ceiling
and attic joists.

Framing and Clearances
A. Selecting Appliance Location
When selecting a location for the appliance it is important to
consider the required clearances to walls (see Figure 5.1).
NOTICE: Illustrations reflect typical installations and are
FOR DESIGN PURPOSES ONLY. Illustrations/diagrams
are not drawn to scale. Actual installation may vary due to
individual design preference.
WARNING! Risk of Fire or Burns! Provide adequate
clearance around air openings and for service access.
Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

B. Constructing the Appliance Chase
To further prevent drafts, the wall shield and ceiling firestops should be caulked with high temperature caulk to
seal gaps. Gas line holes and other openings should be
caulked with high temp caulk or stuffed with unfaced insulation. If the appliance is being installed on a cement
slab, a layer of plywood may be placed underneath to
prevent conducting cold up into the room.
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield
firestops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.
C. Clearances
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.
Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building
envelope in any manner.
WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infiltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.
• Insulation and other materials must be secured to prevent
accidental contact.
• Failure to maintain airspace may cause overheating and
a fire.

Troubleshooting
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 technician in the diagnosis of a problem and the
corrective action to be taken. This troubleshooting guide can only be used by a qualified technician. Contact your dealer to
arrange a service call by a qualified technician.
A. Intellifire Ignition System
Symptom
Possible Cause
a. Incorrect wiring.
1. Pilot won’t light.
The ignitor/module
makes noise, but no
b. Loose connections or electrical
spark.
shorts in the wiring.
2. Pilot won’t light,
there is no noise or
spark.
Corrective Action
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor
are connected to correct terminals on module and pilot assembly.
Verify no loose connections or electrical shorts in wiring from
module to pilot assembly. Verify connections underneath pilot assembly 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.
Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 inch or 1/8 in. (3 mm).
d. Faulty module.
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.
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 wir- Remove and reinstall the wiring harness that plugs into module.
ing configuration or wiring harness. Verify there is a tight fit. Verify pilot assembly wiring to module. Remove and verify continuity of each wire in wiring harness. Replace
any damaged components.
3. Pilot sparks, but
Pilot will not light.
c. Improper wall switch wiring.
Verify that 110/VAC power is “ON” to junction box.
d. Module not grounded.
Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
e. Faulty 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.
a. Correct 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 incorrect.
Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in (3 mm).
c. Module is not grounded.
Verify module is securely grounded to metal chassis of appliance.
d. Module voltage output / Valve/Pilot
solenoid ohms readings.
Verify battery voltage is at least 2.7 volts. Replace batteries if voltage is below 2.7.

Intellifire Ignition System - (continued)
Symptom
4. Pilot lights but continues to spark, and main
burner will not ignite.
(If the pilot continues
to spark after the
pilot flame has been lit,
flame rectification has
not occurred.)
38
Possible Cause
a. A shorted or loose connection in flame
sensing rod.
Corrective Action
Verify all connections to wiring diagram in manual. Verify
connections underneath pilot assembly are tight. Verify
connections are not grounding out to metal chassis, pilot
burner, pilot enclosure or screen if present, or any other
metal object.
b. Poor flame rectification or contaminated With fixed glass assembly in place, verify that flame is enflame sensing rod.
gulfing flame sensing rod on left side of pilot hood. Flame
sensing rod should glow shortly after ignition. Verify correct pilot orifice is installed and gas inlet is set to pressure
specifications.
c. Module is not grounded.
Verify module is securely grounded to metal chassis of
appliance. Verify that wire harness is firmly connected to
the module.
d. Damaged pilot assembly or contaminated flame sensing rod.
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.
e. Faulty 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.
