Hearth & Home Technologies Inc.
LIMITED LIFETIME WARRANTY
Hearth & Home Technologies Inc., on behalf of its hearth brands (”HHT”), extends the following warranty for
HHT gas, wood, pellet, coal and electric hearth appliances that are purchased from an HHT authorized dealer.
WARRANTY COVERAGE:
HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership
of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance
will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered components manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period,
HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its
obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product
itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty
is subject to conditions, exclusions and limitations as described below.
WARRANTY PERIOD:
Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage
begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent,
authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months
following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for
parts and labor for covered components is produced in the following table.
The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for
gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These
time periods reflect the minimum expected useful lives of the designated components under normal operating conditions.

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
When first operated, this appliance 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 appliance. These circumstances may require additional curing
related to the installation environment.
Film on the glass
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.
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 appliance.
Is it normal to see the pilot
flame burn continually?
In an IntelliFire ignition system (IPI), the pilot flame should turn off when appliance is turned off.
Some optional control systems available with IPI models may allow pilot flame to remain lit. In a
standing pilot system the pilot will always stay on.

Carefully remove the appliance and components from
the packaging.
The vent system components and decorative doors and
fronts may be shipped in separate packages.
If packaged separately, the log set and appliance grate
must be installed.
Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
Read all of the instructions before starting the installation.
Follow these instructions carefully during the installation
to ensure maximum safety and benefit.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged,
incomplete or substitute components. Keep appliance dry.
Hearth & Home Technologies disclaims any responsibility for,
and the warranty will be voided by, the following actions:
• Installation and use of any damaged appliance or vent system
component.
• Modification of the appliance or vent system.
• Installation other than as instructed by Hearth & Home

Heatilator • Novus B-Vent Series • 4055-188 • Rev. R • 1/12
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:
•
•
•
Exhaust fans (kitchen, bath, etc.)
Range hoods
Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
• 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.
Ensure adequate outdoor air is supplied for combustion
appliances and exhaust equipment.
Recommended
Location
Location
Not
Recommended
•
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.
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.
Location of the fireplace and chimney will affect performance. As shown in Figure 4.2, the chimney should:
•
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.
• 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. Constructing the Appliance Chase
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.
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.
should be caulked with caulk with a minimum of 300ºF continuous exposure rating to seal gaps. Gas line holes and
other openings should be caulked with caulk with a minimum of 300ºF continuous exposure rating or stuffed with
unfaced insulation. If the appliance is being installed on a
cement surface, a layer of plywood may be placed underneath to prevent conducting cold up into the room.
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.
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. To
further prevent drafts, the wall shield and ceiling firestops
•
Insulation and other materials must be secured to
prevent accidental contact.
•
The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
•
Failure to maintain airspace may cause overheating and
a fire.
Note: If the inside of the framed cavity is to be finished, the framing dimensions must include the finished surface. Example: If
drywall is to be attached to the rear wall, the depth must be measured from the drywall surface.

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 in. or 1/8 in. (3 mm).
d. 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
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. Replace
any damaged components.
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. 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. Gas supply.
Verify that incoming gas line ball valve is “open”. Verify that inlet
pressure reading is within acceptable limits.
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.

A. 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.)
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. Polish flame sensing rod with fine steel wool 
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
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. Polish flame sensing rod with fine steel wool 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. 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.
