B. Limited Lifetime Warranty
Hearth & Home Technologies
LIMITED LIFETIME WARRANTY
Hearth & Home Technologies, 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.

WARRANTY CONDITIONS:
• This warranty only covers HHT appliances that are purchased through an HHT authorized dealer or distributor. A list of
HHT authorized dealers is available on the HHT branded websites.
• This warranty is only valid while the HHT appliance remains at the site of original installation.
• This warranty is only valid in the country in which the HHT authorized dealer or distributor that sold the appliance
resides.
• Contact your installing dealer for warranty service. If the installing dealer is unable to provide necessary parts, contact
the nearest HHT authorized dealer or supplier. Additional service fees may apply if you are seeking warranty service
from a dealer other than the dealer from whom you originally purchased the product.
• Check with your dealer in advance for any costs to you when arranging a warranty call. Travel and shipping charges
for parts are not covered by this warranty.
WARRANTY EXCLUSIONS:
This warranty does not cover the following:
• Changes in surface finishes as a result of normal use. As a heating appliance, some changes in color of interior and
exterior surface finishes may occur. This is not a flaw and is not covered under warranty.
• Damage to printed, plated, or enameled surfaces caused by fingerprints, accidents, misuse, scratches, melted items,
or other external sources and residues left on the plated surfaces from the use of abrasive cleaners or polishes.
• Repair or replacement of parts that are subject to normal wear and tear during the warranty period. These parts
include: paint, wood, pellet and coal gaskets, firebricks, grates, flame guides, batteries and the discoloration of glass.
• Minor expansion, contraction, or movement of certain parts causing noise. These conditions are normal and complaints related to this noise are not covered by this warranty.
• Damages resulting from: (1) failure to install, operate, or maintain the appliance in accordance with the installation
instructions, operating instructions, and listing agent identification label furnished with the appliance; (2) failure to
install the appliance in accordance with local building codes; (3) shipping or improper handling; (4) improper operation, abuse, misuse, continued operation with damaged, corroded or failed components, accident, or improperly/
incorrectly performed repairs; (5) environmental conditions, inadequate ventilation, negative pressure, or drafting
caused by tightly sealed constructions, insufficient make-up air supply, or handling devices such as exhaust fans or
forced air furnaces or other such causes; (6) use of fuels other than those specified in the operating instructions; (7)
installation or use of components not supplied with the appliance or any other components not expressly authorized
and approved by HHT; (8) modification of the appliance not expressly authorized and approved by HHT in writing;
and/or (9) interruptions or fluctuations of electrical power supply to the appliance.
• Non-HHT venting components, hearth components or other accessories used in conjunction with the appliance.
• Any part of a pre-existing fireplace system in which an insert or a decorative gas appliance is installed.
• HHT’s obligation under this warranty does not extend to the appliance’s capability to heat the desired space. Information is provided to assist the consumer and the dealer in selecting the proper appliance for the application. Consideration must be given to appliance location and configuration, environmental conditions, insulation and air tightness of
the structure.
This warranty is void if:
• The appliance has been over-fired or operated in atmospheres contaminated by chlorine, fluorine, or other damaging
chemicals. Over-firing can be identified by, but not limited to, warped plates or tubes, rust colored cast iron, bubbling,
cracking and discoloration of steel or enamel finishes.
• The appliance is subjected to prolonged periods of dampness or condensation.
• There is any damage to the appliance or other components due to water or weather damage which is the result of, but
not limited to, improper chimney or venting installation.
LIMITATIONS OF LIABILITY:
• The owner’s exclusive remedy and HHT’s sole obligation under this warranty, under any other warranty, express or
implied, or in contract, tort or otherwise, shall be limited to replacement, repair, or refund, as specified above. In no
event will HHT be liable for any incidental or consequential damages caused by defects in the appliance. Some states
do not allow exclusions or limitation of incidental or consequential damages, so these limitations may not apply to you.
This warranty gives you specific rights; you may also have other rights, which vary from state to state. 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
EXPRESSED WARRANTY SPECIFIED ABOVE.

M. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass
Blue fl ames
Odor from appliance
Film on the glass
Metallic noise
Is it normal to see the pilot fl ame burn
continually?
This is a result of gas combustion and temperature variations. As the appliance warms, this
condensation will disappear.
This is a result of normal operation and the fl ames will begin to yellow as the appliance is al-
lowed to burn for 20 to 40 minutes.
When fi rst operated, this appliance may release an odor for the fi rst several hours. This is caused
by the curing of the paint and the burning off of any oils remaining from manufacturing. Odor may
also be released from fi nishing materials and adhesives used around the appliance.
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 fi replace 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 appliance.
In an intermittent pilot ignition system (IPI), the pilot fl ame should turn off when appliance is
turned off. Some optional control systems available with IPI models may allow pilot fl ame to
remain lit. In a standing pilot system the pilot will always stay on.

Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system confi guration to be used.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Framing and fi nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualifi ed
service technician, service agency or your dealer.
Installation and service of this appliance should be
performed by qualifi ed personnel. Hearth & Home
Technologies suggests NFI certifi ed or factory

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).
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 traffi c and away from furniture and draperies.

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 be enclosed inside the chase.
NOTICE: Treatment of ceiling fi restops and wall shield
fi restops 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.
Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration 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 fi re-
stops 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.
COMBUSTIBLE FLOORING MAY BE INSTALLED

than wood.
WARNING! Risk of Fire! Maintain specifi ed air space
clearances to appliance and vent pipe:
• 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 fi replace or chimney.
• Failure to maintain airspace may cause overheating and
a fi re.
D. Mantel and Wall Projections
WARNING! Risk of Fire! Comply with all minimum clearances as specifi ed. Framing or fi nishing material closer than
the minimums listed must be constructed entirely of noncombustible materials (i.e., steel studs, concrete board, etc).
