Warranty
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 compo-
nents 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.
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, light bulbs, batteries and the discolor-
ation of glass.
•
•
Minor expansion, contraction, or movement of certain parts causing noise. These conditions are normal and com-
plaints 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 opera-
tion, 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. Informa-
tion is provided to assist the consumer and the dealer in selecting the proper appliance for the application. Consider-
ation 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.

Properly seasoned wood is important for successful opera-

deteriorate over time and will need occasional replacement.
Seasoned firewood is wood that is cut to size, split and air
dried to a moisture content of around 20%.
WARNING! Risk of Fire! Use only the factory-supplied
integral grate.
Imagine a wooden bucket that weighs about eight pounds.
Fill it with a gallon of water, put it in the fireplace and try to
burn it. This sounds ridiculous but that is exactly what you
are doing if you burn unseasoned wood.
•
•
Keeps logs in place.
Allows proper air circulation around the fire.
A tree cut down a year ago and not split is likely to have
almost as high a moisture content now as it did when it was
cut.
E. Firescreen
The firescreen is provided to control sparks. Keep it closed
when the fireplace is in use.
Please refer to Section 2.M. for more detail.
WARNING! Risk of Fire or Burns!
•
Screen will not prevent burning materials from falling
out.
C. Starting a Fire
•
Screen pulls or handles may be hot.
NOTICE: You must establish a good draft to prevent smoke
spillage into the room.
F. Flue Damper
•
•
Refer to Figure 2.1 for location of control.
WARNING! Risk of Fire! Keep combustible materials,
gasoline and other flammable vapors and liquids clear of
the fireplace.
Must be in fully open position (handle up toward the top
of the fireplace) during operation of the fireplace.
Before lighting the fireplace, verify fully open position by
looking up from the inside of the fireplace.
DO NOT:
•
• store flammable materials close to the fireplace
• use gasoline, lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or “freshen up” a fire in
this fireplace.
WARNING! Risk of Fire and Asphyxiation! Open
damper prior to operating fireplace. A closed damper
overfires the fireplace and will cause smoke and flames
to spill into the room.
Keep all flammable liquids well away from the fireplace while
it is in use. Combustible materials may ignite.
•
The first three or four fires should be of moderate size to
allow the oils and binders to be burned from the fireplace
and molded brick panel, and paint to cure. You may notice
an industrial odor the first few fires. This is considered
normal.
G. Outside Air
•
•
Refer to Figure 2.1 for location of controls.
Outside air doors should be in the fully opened position
during operation of the fireplace.
•
Before lighting the fireplace, turn both handles & pull out
to open. Reverse steps to close and lock.
•
•
•
•
Use well-seasoned wood (see Section 2.M.).
Open the flue damper to a fully open position.
Open outside air.
Place crumpled or twisted paper under the fireplace
grate.
H. Molded Brick Panel
•
The molded brick panel is shipped separately, but required
to contain heat and provide an attractive interior.
It will deteriorate over time and will need occasional
replacement. Small hairline cracks and discoloration are
normal and do not affect its safety.
Cracks in the mortar may occur and do not affect the
safety of the unit. If mortar falls out of the joints and metal
is exposed, replace or patch the mortar.
•
•
Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the fireplace grate.
•
Pre-warm the flue to establish a draft to help reduce smoke
spillage during start-up. Hold a rolled up piece of burning
newspaper under the flue damper for a few moments.
Light the crumpled paper to ignite the kindling.
Add small pieces of wood until a hot bed of embers has
been established.
Add a minimum of three average size pieces of split
firewood, placed to allow combustion air and flames
between them.
•
•
•
•
(See Molded Brick Panel Maintenance, Section 3.C.)
•
WARNING! Risk of Fire! DO NOT burn fireplace without
molded brick panel. Use only molded brick panel supplied
by Hearth & Home Technologies, Inc.
CAUTION! Odors and vapors released during initial op-
eration may be irritating to sensitive individuals. Open
windows for air circulation.
NOTICE: Do not substitute for HHT mortar. Other materials
may stain the molded brick panels.

Your fireplace performance depends on the quality of the
firewood you use.
-
-
Soft wood - about nine months
Hard wood - about eighteen months
•
•
•
•
Seasoned wood contains about 8,000 BTUs per pound .
Hard woods are more dense than soft woods.
Hard woods contain 60% more BTUs than soft woods.
Hard woods require more time to season, burn slower and
are harder to ignite.
NOTICE: Seasoning time may vary depending on drying
conditions.
•
•
•
Soft woods require less time to dry, burn faster and are
easier to ignite.
Start the fire with soft wood to bring the fireplace up to
operating temperature and to establish draft.
Add hard wood for slow, even heat and longer burn
time.
Storing Wood
Steps to ensure properly seasoned wood:
•
•
•
•
Stack wood to allow air to circulate freely around and
through woodpile.
Elevate wood pile off ground to allow air circulation
underneath.
Smaller pieces of wood dry faster. Any piece over 6 in.
(152 mm) in diameter should be split.
Wood (whole or split) should be stacked so both ends of
each peice are exposed to air. More drying occurs through
the cut ends than the sides.
Soft woods
Hard woods
•
•
•
•
•
•
•
Douglas Fir
Pine
•
•
•
•
Oak
Maple
Apple
Birch
Spruce
Cedar
Poplar
Aspen
Alder
•
Store wood under cover to prevent water absorbtion
from rain or snow. Avoid covering the sides and ends
completely.
WARNING! Fire Risk! DO NOT store wood:
• in front of the fireplace.
• in space required for loading or ash removal.
Moisture
WARNING! Risk of Fire!
•
Do not burn wet or green wood.
Processed Solid Fuel Firelogs
•
Wet, unseasoned wood can cause accumulation of
creosote.
Manufactured firelogs may be used with this fireplace.
Hearth & Home Technologies Inc. recommends the use of
UL Classified processed fuel firelogs. Follow the manufac-
turer’s lighting and safety instructions.
The majority of the problems fireplace owners experience
are caused by trying to burn wet, unseasoned wood.
•
Wet, unseasoned wood requires energy to evaporate the
water instead of heating your home, and
Evaporating moisture cools your chimney, accelerating
formation of creosote.
Using firelogs may require more frequent chimney inspec-
tion and cleaning.
•
Do not poke or stir the logs while they are burning. Use
only firelogs that have been evaluated for the application in
manufactured fireplaces and refer to firelog warnings and
caution markings on packaging prior to use.

B. Chimney Inspection/Cleaning
A. Disposal of Ashes
Frequency: At least twice a year during heating season or
as recommended by a certified chimney sweep
By: Certified chimney sweep
Frequency: When they reach bottom of grate
By: Homeowner
WARNING! Risk of Fire! Ashes could contain hot embers.
WARNING! Risk of Fire! Ignited creosote is extremely
HOT. Prevent creosote buildup.
•
•
Place ashes in a metal container with a tight-fitting lid.
The closed container should be placed on a non-
combustible floor or on the ground, well away from all
combustible materials, pending final disposal.
Refer to Figure 3.1 to remove/reinstall termination caps.
Creosote - Formation and Need for Removal
•
If the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled.
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture to
form creosote. The creosote vapors condense in the rela-
tively cool chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on the flue lining. When
ignited this creosote makes an extremely hot fire.
WARNING! Risk of Fire! A chimney fire can permanently
damage your chimney system and nearby structures.
In the event of a chimney fire, Hearth & Home Technolo-
gies Inc. recommends
•
•
replacement of the chimney, and
inspection of the adjacent structure to the provisions of
NFPA Level III inspection criteria
The chimney shall be inspected at least twice a year during
the heating season to determine when a creosote buildup
has occurred.
When creosote has accumulated it shall be removed to
reduce the risk of a chimney fire.

B. Design and Installation Considerations
D. Negative Pressure
WARNING! Risk of Asphyxiation! Negative pressure can
cause spillage of combustion fumes and soot. Fire must
draft properly for safe operation.
NOTICE: Check building codes prior to installation.
•
Installation MUST comply with local, regional, state and
national codes and regulations.
•
Consult insurance carrier, local building inspector, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Negative pressure results from the imbalance of air avail-
able for the fireplace to operate properly. It can be stron-
gest in lower levels of the house.
Causes include:
Before installing, determine the following:
•
•
•
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 such as:
- Recessed lighting
•
•
•
•
•
Where the fireplace is to be installed.
The vent system configuration to be used.
Gas supply piping.
Framing and finishing details.
Whether optional accessories are desired.
•
•
•
•
C. Draft
Draft is the pressure difference needed to vent fireplaces
successfully. When a fireplace is drafting successfully, all
combustion by-products are exiting the home through the
chimney.
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
Considerations for successful draft include:
•
•
•
Ensure adequate outdoor air for all 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
•
•
Preventing negative pressure
Location of fireplace and chimney
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the fireplace
system caused by:
•
•
•
•
•
•
•
•
Inadequate draft due to environmental conditions
Downdrafts
Tight sealing construction of the structure
Mechanical exhausting devices
Improper positioning of the chimney in a not-recommended
location on the roof.
•
Basement installations should be avoided
NOTICE: The fireplace provides some outside air for
combustion. Other methods may be necessary if more air
is required.
NOTICE: Hearth & Home Technologies Inc. recommends the
use of direct vent appliances in basements.

E. Locating your Fireplace & Chimney
Location of the fireplace and chimney will affect perfor-
mance.
•
Install within the warm air 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 loading.
Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
Minimize the use of chimney offsets.
•
•
Consider the fireplace location relative to floor and ceiling
and attic joists.
•
Take into consideration the termination requirements in
Section 8 and Section 9.
NOTICE: Locating the fireplace in an area of considerable
air movement can cause intermittent smoke spillage from
fireplace. Do not locate fireplace near

•
•
•
Measure the total vertical height of the fireplace installation
from the base of the fireplace assembly to the approximate
location of the bottom of the termination cap.
Subtract the effective height of the fireplace assembly (see
Figure 8.2) from the total vertical height to determine the
overall height of the chimney installation.
Create a schematic for your application similar to Figure
8.2 showing components required (referring to Table 8.1).

B. Using Offsets/Returns
•
•
Use an offset/return to bypass overhead obstructions.
An offset and return can be used as a single entity or separated by chimney section(s).
WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause
overheating and fire.
•
•
•
Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 8.3.
Find the appropriate A dimension listed in Table 8.2.
The B dimension coinciding with the A dimension measurement in Table 8.2 represents the required vertical clearance
needed to complete the offset/return.
•
Read across the chart to find the number of chimney sections/model numbers needed between the offset and return.
Example:
A
Your “A” dimension from Figure 8.3 is 14 1/2 in. (368
mm). Using Table 8.2 the dimension closest to, but not
less than 14 1/2 in. (368 mm) is 15 3/4 in. (400 mm) using
a 30° offset/return.
B
You determined from the table that you would need
36 5/8 in. (930 mm) (Dimension “B”) between the offset
and return.
The chimney component that best fits your application is
two SL1112s.

C. Assemble Chimney Sections
WARNING! Risk of Fire! DO NOT install substitute or dam-
aged chimney components.
•
Use only those components described in this manual.
Substitute or damaged chimney components could impair
safe operation and cause overheating and fire.
•
Support the pipe during construction and check to be sure
inadvertent loading has not dislodged the chimney section
from the fireplace or at any chimney joint.
•
•
Attach a straight chimney section or an offset to the top
of the fireplace.
Place inner flue to the inside of the chimney section below
it. Place the outer casing outside the outer casing of the
chimney section below it. Refer to Figure 8.4.
Figure 8.4 Assembling Chimney Sections
NOTICE: Chimney sections cannot be disassembled once
locked together. Plan ahead!
•
Lock chimney sections and/or offsets/returns together by
pushing downward until the top section meets the stop
bead on the lower section.
•
•
Pull on the top section to make sure it is fully engaged
and will not separate.
You may use #6 or #8 sheet metal screws no longer than
1/2 in. (13 mm) to fasten chimney sections together. Do
NOT penetrate inner flue.
WARNING! Risk of Fire! You MUST use screws (pro-
vided) to fasten offset/returns to chimney sections to
keep the chimney parts from twisting. Failure to do so
could cause fire.
•
Fasten offset/returns to chimney sections. Insert the
screws (provided) through the predrilled holes. Do NOT
penetrate inner flue.
•
•
Secure chimney returns with hanger straps (provided);
fasten to studs or joists.
Vertical straight runs of chimney must be supported every
35 ft (10.7 m).

Chase Installations
9
Gas line holes and other openings should be caulked with
high temperature caulk or stuffed with unfaced fiberglass
insulation. If the fireplace is being installed on a cement
slab, we recommend that in cold climates, a sheet of
plywood or other raised platform be placed underneath to
prevent conducting cold up into the room.
A. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
fireplace and/or its vent system. Vertical chimneys that
run on the outside of a building must be installed inside a
chase.
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.
Three examples of chase applications are shown in Fig-
ure 9.2.
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney offset through exterior wall and enclosed in chase.
3. Chase constructed on roof.
A chase 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. All outer walls need to be insulated.
Note: In cooler climates, all chase walls should be insulated.
Building codes require false ceiling and ceiling firestops
at each floor of the chase or every 10 ft (3.05 m) of clear
space to control spread of fire.
Walls, ceiling, base plate and cantilever floor at the first
level of the chase should be insulated. See Figure 9.1.
Vapor and air infiltration barriers should be installed in the
chase as per regional codes for the rest of the home. Addi-
tionally, Hearth & Home Technologies recommends that the
inside surfaces be sheet rocked and taped (or the use of an
equivalent method) for maximum air tightness.

Mix approximately 1/3 of the mortar material with 1/2
gallon of water in the mixing bucket. Stir the mixture with
the mixing attachment and drill. The consistency should
allow the material to be squeezed from the mortar bag but
not too runny.
Fill the mortar bag with the prepared mixture.
Apply mortar by squeezing the material from the mortar
bag into the joint lines. If filling a vertical line, start from
the top and work down. Apply slowly. Mixture should be
flush or higher than the panel surface.
Mix more material as necessary to finish the job and then
let the unit set until firm, may take two hours or more.
Thoroughly clean the bag, tools and mixing bucket.
Use a joint striker and strike the material in the joints. The
excess material should fall off somewhat dry.
Sweep the loose material off the floor of the unit.
Final cleanup with sponge and water.
F. Install Mortar
Note: We recommend mortar be applied after
facing materials are installed.
Tools Required:
•
•
Mortar bag
Drill
Trowel
3/32 drill bit (provided)
Phillips screwdriver
Joint striker
Mixing bucket
Sponge or spray bottle
•
Drill with mixing attachment (optional)
Bucket of water
•
•
The mortar material provided should be sufficient to com-
plete the installation of the molded brick panels without
considerable waste.
•
•
•
VERY IMPORTANT: Allow the mortar 72 hours to cure
before operating the fireplace.
NOTICE: Do not substitute for HHT mortar. Other materials
may stain the molded brick panels.
Mortar should be applied
after finishing material is
installed. Mortar will be
applied between finishing
materials and molded
brick edges, bottom and
sides.
The non-combustible finishing
material across the top of
fireplace opening will be even
with lower edge of metal face.
Non-combustible finishing
materials MUST overlap
side faces by 1 1/4 in. (32 mm)
to cover the edges of the
panels. Finished opening
should be 38 x 42 in. (965 x
1067 mm) to allow for door
installation.
The seam between
finishing materials and
firebox top must be sealed
with non-combustible
sealant.
The surface of the finished hearth extension and
the surface of the hearth panel should be level.
