it may be necessary to decrease the input rating by chang-
ing the existing burner orifice to a smaller size. Input rate
should be reduced by 4% for each 1000 ft above a 2000 ft
elevation in the U.S.A., or 10% for elevations between 2000
and 4500 ft in Canada. If the heating value of the gas has
been reduced, these rules do not apply. To identify the prop-
er orifice size, check with the local gas utility.
NOT INTENDED FOR USE AS A PRIMARY HEAT
SOURCE. This appliance is tested and approved as either
supplemental room heat or as a decorative appliance. It
should not be factored as primary heat in residential heating
calculations.

Getting Started
2
A. Design and Installation Considerations
Heatilator B-vent gas appliances are designed to operate
with all exhaust gases expelled to the outside of the building,
and combustion air pulled from the room.
CAUTION
Check building codes prior to installation.
•
Installation MUST comply with local, regional,
state and national codes and regulations.
•
Consult insurance carrier, local building, fire
officials or authorities having jurisdiction about
restrictions, installation inspection, and permits.
When planning an appliance installation, it’s necessary to
determine the following information before installing:
•
Where the appliance is to be installed. See Sections 3
and 4.
•
The vent system configuration to be used. See Sections
5 and 6.
•
•
•
Gas supply piping. See Sections 7 and 9.
Electrical wiring. See Sections 7 and 10
Framing and finishing details. See Sections 3, 6
and 11.
•
Whether optional accessories—devices such as a fan, wall
switch, or remote control—are desired. See Section 16.
WARNING
Keep appliance dry.
•
Mold or rust may cause
odors.
•
Water may damage controls.

To minimize the effects of negative air pressure, the follow-
ing must be considered:
B. Negative Pressure
•
Install the outside air kit. Install the intake on the side of
the house towards prevailing winds during the heating
season.
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 a “sealed can” design; attic
hatches weather stripped or sealed; attic mounted duct
work and air handler joints and seams taped or sealed.
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.
WARNING
Asphyxiation Risk
•
•
•
•
•
Negative pressure can cause spillage of
combustion fumes and soot.
Fire needs to draft properly for safe
operation.
•
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
Negative pressure results from the imbalance of air avail-
able for the fireplace to operate properly. Causes for this
imbalance include:
Location of the fireplace and chimney will affect performance.
As shown in Figure 2.1 the chimney should:
•
•
•
Exhaust fans (kitchen, bath, etc.).
Range hoods.
Combustion air requirements for furnaces, water heaters
and other combustion appliances.
Clothes dryers.
Location of return-air vents to furnace or air
conditioning.
Imbalances of the HVAC air handling system.
Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks).
•
Be installed through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fire.
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.

B. Construct the Appliance Chase
WARNING
A chase is a vertical boxlike structure built to enclose the gas
appliance and/or its vent system. Vertical vents that run on
the outside of a building may be, but are not required to be,
installed inside a chase.
Fire Risk
•
•
Construct chase to all clearance
specifications in manual.
Locate and install appliance to all
clearance specifications in manual.
Construction of the chase may vary with the type of build-
ing. These instructions are not substitutes for the require-
ments of local building codes. Local building codes MUST
be checked.
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.
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, Hearth & Home Technologies recom-
mends that the inside surfaces be sheet rocked and taped
(or the use of an equivalent method) for maximum air tight-
ness.
To further prevent drafts gas line holes and other openings
should be caulked with high temp caulk or stuffed with un-
faced insulation. If the appliance is being installed on a ce-
ment slab, we recommend that a layer of plywood be placed
underneath to prevent conducting cold up into the room.

I. Air Shutter Setting
This appliance has an adjustable air shutter (which controls
the primary air) factory set for the minimum vertical vent run
(see Figure 12.10). If your installation has more than the
minimum required vertical vent length, adjustment of the air
shutter may be necessary to obtain optimal flame appear-
ance. This should be adjusted by a qualified installer at
the time of installation.
•
If the vent configuration is installed incorrectly, the
vent may cause the flames inside the appliance to lift
or “ghost,” which is a dangerous situation. Inspect the
flames after installation to ensure proper performance. If
the vent configuration is correct, yet the flames are lifting
or ghosting, shut off the gas to the appliance and contact
the dealer.
Figure 12.10Air Shutter
•
Your air shutter is provided at 1/8 in. open for natural
gas, 3/8 in. open for propane (30 in./33 in. appliances),
and full open for 36 in. and 42 in. propane appliances. In
the event soot is accumulating in your appliance, the air
shutter should be opened farther. This can be done by
opening the control access panel and locating the two wing
studs and two wing nuts attaching the valve assembly to
the firebox. Remove the wing nuts and wing studs, slide
the valve assembly to the left and lower. Rotate the valve
assembly horizontally and remove from underneath the
appliance. See Figure 12.11.
Note: To avoid damage to the pilot assembly,
remove the valve assembly pilot side first.
If the valve assembly gasket is damaged, it
should be replaced.

E. Frequently Asked Questions
Issue
Solutions
Condensation on the glass
This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will
disappear.
Blue flames
This is a result of normal operation and the flames will begin to yellow as the appliance is allowed to burn for 20 to
40 minutes.
Odor from appliance
Film on the glass
When first operated, this appliance may release an odor for the first several hours. This is caused by the curing of
the paint and the burning off of any oils remaining from manufacturing.
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 to remove deposits left by oils from the manufacturing process. A non-abrasive cleaner such as gas
fireplace glass cleaner may be necessary. See your dealer.
Metallic noise
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.
Is it normal to see the pilot
In an Intellifire ignition system it is normal to see the pilot flame, but it should turn off when ON/OFF is turned off.
flame burn continually?
In a standing pilot system the pilot will always stay on.

Troubleshooting
14
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 person 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.
A. Standing Pilot Ignition System
Symptom
Possible Causes
Corrective Actions
1.
After repeated triggering
of the red or black piezo
ignitor button, the spark
ignitor will not light the
pilot.
A.
B.
Defective ignitor.
Check the spark at the electrode and pilot. If there is no spark and the
electrode wire is properly connected, replace the ignitor.
Defective pilot or
misaligned electrode
(spark at electrode).
Using a match, light the pilot. If the pilot lights, turn off the pilot and trigger
the red or black piezo ignitor button again. If the pilot lights, an improper
gas/air mixture caused the bad lighting and a longer purge period is
recommended. If the pilot will not light, ensure the gap at the electrode and
pilot is 1/8 in. to have a strong spark. If the gap is OK, replace the pilot.
C.
No gas or low gas
pressure.
Check the remote shut-off valves from the appliance. There is usually a
valve near the gas main. There can be more than one valve between the
appliance and the main.
D.
A.
No LP in tank.
Check the LP (propane) tank. You may be out of fuel.
2.
The pilot will not stay lit
after carefully following
the lighting instructions
Defective thermocouple.
Check that the pilot flame impinges on the thermocouple. Clean and/or
adjust the pilot for maximum flame impingement.
Ensure that the thermocouple connection at the gas valve is fully inserted
and tight (hand tighten plus 1/4 turn).
Disconnect the thermocouple from the valve, place one millivolt meter lead
wire on the tip of the thermocouple and the other meter lead wire on the
thermocouple copper lead. Start the pilot and hold the valve knob in. If the
millivolt reading is less than 15mV, replace the thermocouple.
B.
A.
Defective valve.
If the thermocouple is producing more than 15 millivolts, replace faulty valve.
3.
The pilot is burning, there
is no gas burning, the
valve knob is in the ON
position, and the ON/
OFF switch is in the ON
position.
ON/OFF switch or wires
are defective.
Check the ON/OFF switch and wires for proper connections. Place the
jumper wires across the terminals at the switch. If the burner comes on,
replace the defective switch. If the switch is OK, place the jumper wires
across the switch wires at the gas valve. If the burner comes on, the wires
are faulty or connections are bad.
B.
Thermopile may not be
generating sufficient
millivoltage.
If the pilot flame is not close enough physically to the thermopile, adjust the
pilot flame.
Be sure the wire connections from the thermopile at the gas valve terminals
are tight and that the thermopile is fully inserted into the pilot bracket.
Check the thermopile with a millivolt meter. Take the reading at TH-TP&TP
terminals of the gas valve. The meter should read 325 millivolts minimum
while holding the valve knob depressed in the pilot position, with the pilot lit,
and the ON/OFF switch in the OFF position. Replace the faulty thermopile of
the reading is below the specified minimum.
With the pilot in the ON position, disconnect the thermopile leads from
the valve. Take a reading at the thermopile leads. The reading should be
325 millivolts minimum. Replace the thermopile if the reading is below the
minimum.
C.
Defective valve.
Turn the valve knob to the ON position. Place the ON/OFF switch in the ON
position. Check the millivolt meter at the thermopile terminals. The millivolt
meter should read greater than 125mV. If the reading is acceptable, and if
the burner does not come on, replace the gas valve.
D.
E.
Plugged burner orifice.
Check the burner orifice for stoppage. Remove stoppage.
Wall switch or wires are
defective.
Follow the corrective action in Symptom and Possible Cause 1.A. above.
Check the switch and wiring. Replace where defective.

B. Intellifire Ignition System
Symptom
Possible Causes
Corrective Actions
1.
The ignitor/module makes
noise, but no spark.
A.
B.
Incorrect wiring.
Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are
connected to the correct terminals on the module and the pilot assembly.
Reversed wires at the module may cause the system to make a sparking
noise, but the spark may not be present at pilot hood.
Loose connections or
electrical shorts in the
wiring.
Verify there are no loose connections or electrical shorts in wiring from
module to pilot assembly. The rod closest to the pilot hood should be ignitor.
Verify connections underneath pilot assembly are tight; also verify the
connections are not grounding out to the metal chassis, pilot burner, pilot
enclosure, mesh screen if present, or any other metal object.
C.
D.
Ignitor gap is too large.
Faulty module.
Verify gap of ignitor to pilot hood. The gap should be approximately .17 in. or
1/8 in.
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. Hold ground wire about 3/16 in. away from “I” terminal on module. 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.
2.
Pilots won’t light, there is
no noise or spark.
A.
B.
Transformer installed
incorrectly.
Verify that transformer is installed and plugged into module. Check voltage of
transformer under load at space 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.
A shorted or loose
connection in wiring
configuration or wiring
harness.
Remove and reinstall the wiring harness that plugs into module. Verify there is
a tight fit. Verify pilot assembly wiring to module. Remove and verify continuity
of each wire in wiring harness.
C.
D.
E.
Improper wall switch
wiring.
Verify wall switch is wired correctly.
Module not grounded.
Verify black ground wire from module wire harness is grounded to metal
chassis of appliance.
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. Hold ground wire about 3/16 in. away from “I” terminal on module. 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 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.)
A.
B.
A shorted or loose
connection in sensor rod.
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.
Poor flame rectification or
contaminated sensor rod.
Verify flame is engulfing sensor rod. If the pilot assembly does not have a
ground strap, consider installing one to increase flame rectification. Verify
correct pilot orifice is installed and inlet gas specifications are met. Flame
carries rectification current, not the gas. If flame lifts from pilot hood, the
circuit is broken. A wrong orifice or too high an inlet pressure can cause pilot
flame to lift. The sensor rod may be contaminated. Clean sensor rod with
emery cloth.
C.
D.
Module is not grounded.
Verify that module is securely grounded to metal chassis of appliance. Verify
that the wire harness is firmly connected to module.
Damaged pilot assembly
or dirty sensor rod.
Verify that ceramic insulator around the sensor rod is not cracked, damaged,
or loose. Verify connection from sensor rod to white sensor wire. Clean
sensor rod with emery cloth to remove any contaminants that may have
accumulated on sensor rod. Verify continuity with a multimeter with ohms set
at lowest range.
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. Hold ground wire about 3/16 in. away from “I” terminal on module. 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.

Conditions, Exclusions, & Limitations of Liability
A. Both the Limited Lifetime and 1 Year Limited Warranties supplied by HHT apply only while the Appliance is in its location of original
installation. HHT’s obligation under this warranty does not extend to damages resulting from (1) installation, operation or maintenance
of the Appliance not in accordance with the Installation Instructions, Operating Instructions, and the Listing Agent Identification Label
furnished with the Appliance; (2) installation which does not comply with local building codes; (3) shipping, improper handling, improper
operation, abuse, misuse, accident or unworkmanlike repairs; (4) environmental conditions, inadequate ventilation or drafting caused by
tight sealing construction of the structure, air handling devices such as exhaust fans or forced air furnaces, or other causes; (5) use of
fuels other than those specified in the Operating Instructions; (6) installation or use of components not supplied with the Appliance or any
other components not expressly authorized and approved by HHT; and/or (7) modification of the Appliance not expressly authorized and
approved by HHT in writing. This warranty is limited to only the component parts manufactured or supplied by HHT.
B. HHT’s liability under both the Limited Lifetime Warranty and the 1 Year Limited Warranty is limited to the replacement and repair of
defective components or workmanship during the applicable period. HHT may fully discharge all of its obligations under such warranties
by repairing the defective component(s) or at HHT’s discretion, providing replacement parts at no charge and paying reasonable labor
and freight costs.
C. EXCEPT TO THE EXTENT PROVIDED BY LAW, HHT MAKES NO EXPRESS WARRANTIES OTHER THAN THE WARRANTY
SPECIFIED HEREIN. THE DURATION OF ANY IMPLIED WARRANTY IS LIMITED TO DURATION OF THE WARRANTY SPECIFIED
ABOVE.
D. Some states do not allow exclusions or limitations of incidental or consequential damages, so those limitations may not apply to you.
This warranty gives you specific rights; you may also have other rights which vary from state to state.
