A. Your Fireplace
WARNING! DO NOT operate fi replace before reading and understanding operating instructions. Failure to operate fi replace
according to operating instructions could cause fi re or injury.
Properly seasoned wood is important for successful
operation of your fi replace. Most woodburning fi replace
problems are caused by burning wet, unseasoned wood.
Seasoned fi rewood is wood that is cut to size, split and air
dried to a moisture content of around 20%.
Imagine a wooden bucket that weighs about eight
pounds. Fill it with a gallon of water, put it in the fi replace
and try to burn it. This sounds ridiculous but that is exactly
what you are doing if you burn unseasoned wood.
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.
Please refer to Section 2.M for more detail.
C. Starting a Fire
NOTICE: You must establish a good draft to prevent smoke
spillage into the room.
WARNING! Risk of Fire! Keep combustible materials,
gasoline and other fl ammable vapors and liquids clear of
the fi replace.
DO NOT:
• store fl ammable materials close to the fi replace
• use gasoline, lantern fuel, kerosene, charcoal lighter
fl uid or similar liquids to start or “freshen up” a fi re in this
fi replace.
Keep all fl ammable liquids well away from the fi replace while
it is in use. Combustible materials may ignite.
D. Grate
This fi replace is designed to be used with the grate sup-
plied with this unit or one approved by HHT. The grate will
break down over time and will need occasional replacement.
WARNING! Risk of Fire!
integral grate.
• Keeps logs in place.
• Allows proper air circulation around the fi re.
Use only the factory-supplied
E. Firescreen
The fi rescreen is provided to control sparks. Keep it
closed when the fi replace is in use.
WARNING! Risk of Fire or Burns!
• Screen will not prevent burning materials from falling
out.
• Screen pulls or handles may be hot.
F. Flue Damper
• Refer to Figure 2.1 for location of control.
• Must be in fully open position (handle up toward the top
of the fi replace) during operation of the fi replace.
• Before lighting the fi replace, verify fully open position by
looking up from the inside of the fi replace.
WARNING! Risk of Fire and Asphyxiation! Open
damper prior to operating fi replace. A closed damper
overfi res the fi replace and spills smoke and fl ames
into the room.
• The fi rst three or four fi res should be of moderate size to
allow the oils and binders to be burned from the fi replace
and the refractory and paint to cure. You may notice
an industrial odor the fi rst few fi res. This is considered
normal.
• Use well-seasoned wood.
• Open the fl ue damper to a fully open position.
• Place crumpled or twisted paper under the fi replace
grate.
• Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the fi replace grate.
• Pre-warm the fl ue to establish a draft to help reduce
smoke spillage during start-up. Hold a rolled up piece
of burning newspaper under the fl ue 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
fi rewood, placed to allow combustion air and fl ames
between them.
CAUTION! Odors and vapors released during initial
operation may be irritating to sensitive individuals.
Open windows for air circulation.
G. Refractory
• The refractory is supplied to contain heat and provide
an attractive interior.
• It will break down over time and will need occasional
replacement. Small hairline cracks and discoloration are
normal and do not affect its safety.
• (See refractory maintenance Section 3.C.)
WARNING! Risk of Fire! DO NOT burn fi replace with-
out refractory. Use only refractory supplied by Hearth &
Home Technologies, Inc.
• Refer to Figure 2.2 for how to properly use them.
WARNING! Risk of Fire! Install ONLY doors ap-
proved by Hearth & Home Technologies, Inc.
WARNING! Risk of Fire and Smoke! Fireplaces
equipped with doors should be operated only with
doors fully open or doors fully closed. If doors are left
partly open, gas and fl ame may be drawn out of the fi replace opening.

I. Outside Air (optional)
The outside air kit supplies some combustion air for your
fi replace. It may help reduce the effects of negative air
pressure. (See Section 5.D.)
• Refer to Figure 2.1 for location of control
• Close the inlet to prevent cold drafts when the fi replace
is not being used.
CAUTION! Risk of Burns! The outside air control
handle is HOT when fi replace is in operation. Adjust
BEFORE lighting fi re.
L. Clear Space
• Do not place combustible objects within areas indicated
in Figure 2.3.
WARNING! DO NOT place combustible objects in front
of the fi replace. High temperatures may ignite clothing,
furniture or draperies.
• Mantel - avoid placing candles and other heat-sensitive
objects on mantel or hearth. Heat may damage these
objects.
Your fi replace performance depends on the quality of the
fi rewood you use.
• 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.
• Soft woods require less time to dry, burn faster and are
easier to ignite.
• Start the fi re with soft wood to bring the fi replace up to
operating temperature and to establish draft.
• Add hard wood for slow, even heat and longer burn
time.
Soft woods Hard woods
• Douglas Fir • Oak
• Pine • Maple
• Spruce • Apple
• Cedar • Birch
• Poplar
• Aspen
• Alder
Moisture
WARNING! Risk of Fire!
• DO NOT burn wet or green wood.
• Wet, unseasoned wood can cause accumulation of
creosote.
The majority of the problems fi replace 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.
Seasoned Wood
• Cut logs to size
• Split to 6 in. (152 mm) or less
• Air dry to a moisture content of around 20%
- Soft wood - about nine months
- Hard wood - about eighteen months
NOTICE: Seasoning time may vary depending on drying
conditions.
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.
• 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 fi replace.
• In space required for loading or ash removal.
Processed Solid Fuel Firelogs
Manufactured fi relogs may be used with this fi replace.
Hearth & Home Technologies Inc. recommends the use of
UL Classifi ed processed fuel fi relogs. Follow the manufac-
turer’s lighting and safety instructions.
Using fi relogs may require more frequent chimney inspec-
tion and cleaning.
Do not poke or stir the logs while they are burning. Use
only fi relogs that have been evaluated for the application
in manufactured fi replaces and refer to fi relog warnings
and caution markings on packaging prior to use.
Frequency: When they reach bottom of grate
By: Homeowner
WARNING! Risk of Fire! Ashes could contain hot embers.
• Place ashes in a metal container with a tight-fi tting lid.
• The closed container should be placed on a
noncombustible fl oor or on the ground, well away from
all combustible materials, pending fi nal disposal.
• 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.
B. Chimney Inspection/Cleaning
Frequency: At least twice a year during heating season
or as recommended by a certifi ed chimney sweepBy: Certifi ed chimney sweep
WARNING! Risk of Fire! Ignited creosote is extremely
HOT. Prevent creosote buildup.
Refer to Figure 3.1 to remove/reinstall termination caps.
Creosote - Formation and Need for Removal
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 relatively cool chimney fl ue of a slow-burning fi re. As a result,
creosote residue accumulates on the fl ue lining. When
ignited this creosote makes an extremely hot fi re.
WARNING! Risk of Fire! A chimney fi re can permanently
damage your chimney system and nearby structures.
In the event of a chimney fi re, 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 fi re.
Remove 2 screws from
the front and back and
lift the top off.

C. Check Firebox Refractory
Frequency: After each ash removal
By: Homeowner
WARNING! Risk of Fire!
Crumbling, deteriorated refractory can allow overheating
of surrounding materials.
Expansion and contraction will cause minor cracking of
the refractory. This is normal. The refractory will require
periodic replacement depending on use.
The panels should be replaced if
• Cracks exceed ¼ inch (6 mm) in width,
• Metal is exposed behind the refractory,
• Large pieces of refractory fall out.
Inspect fi replace refractory.
D. Inspect Grate
Frequency: After each ash removal
By: Homeowner
Inspect grate for:
• Warping or sagging 1-1/2 in. (38 mm) or more
• Broken welds
• Burn-through of grate bars
For safe operation, replace only with an approved grate
from Hearth & Homes Technologies Inc.
E. Glass Cleaning
Frequency: As desired
By: Homeowner
CAUTION! Handle glass assembly with care. Glass is
breakable.
• Avoid striking, scratching or slamming glass
• Avoid abrasive cleaners
• DO NOT clean glass while it is hot
Clean glass with a non-abrasive commercially available
cleaner or ashes:
• Light deposits
- Use household glass cleaner
• Heavy deposits
- Use wood ash on damp cloth or,
- Use commercial fi replace glass cleaner (consult with
your dealer)
D. Negative PressureB. Design and Installation Considerations
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, fi re
offi cials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Before installing, determine the following:
• Where the fi replace is to be installed
• The vent system confi guration to be used
• Gas supply piping
• Electrical wiring
• Framing and fi nishing details
• Whether optional accessories—devices such as a fan,
wall switch or remote control —are desired
NOTICE: Junction box should be installed during initial
setup to avoid major reconstruction.
C. Draft
Draft is the pressure difference needed to vent fi replaces
successfully. When a fi replace is drafting successfully, all
combustion byproducts are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of fi replace and chimney
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the fi replace
system caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Improper location of the chimney
WARNING! Risk of Asphyxiation! Negative pressure
can cause spillage of combustion fumes and soot. Fire
must draft properly for safe operation.
Negative pressure results from the imbalance of air available for the fi replace to operate properly. It can be stron-
gest in lower levels of the house.
Causes 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 vents to furnace or air
conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
• Install the outside air kit with the intake facing prevailing
winds during the heating season
• 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 fi replace
• Avoid installing the fi replace 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
NOTICE: Hearth & Home Technologies Inc. recommends
Location of the fi replace and chimney will affect perfor-
mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fi re.
• 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 fi replace location relative to fl oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Section 8 and Section 9.
NOTICE: Locating the fi replace in a basement or in a location
of considerable air movement can cause intermittent smoke
spillage from fi replace. Do not locate fi replace near

so may cause overheating and fi re.
Table 8.1
Determine the chimney components needed to complete
your particular installation:
• Measure the total vertical height of the fireplace
installation from the base of the fi replace assembly to
the approximate location of the bottom of the termination
cap.
• Subtract the effective height of the fi replace 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). Figure 8.1 identifi es those components and where
used.
• Install a ceiling fi restop whenever the chimney penetrates
a fl oor/ceiling.
NOTICE: A maximum of two pairs of offsets and returns
may be used.
CAUTION! Risk of Fire and/or Asphyxiation! DO
NOT connect this fi replace to a chimney fl ue servicing
another appliance. DO NOT connect to any air distribution duct or system. These actions could cause overheating/fi re in the chimney fl ue, or release of exhaust
fumes into the living areas.

Proper assembly of air-cooled chimney parts result in an overlap at chimney joints of 1-1/4 in. (32 mm). Effective length is built
into this chart.
WARNING! Risk of Fire! DO NOT install substitute or
damaged chimney components.
• Use only those components described in this manual.
Substitute or damaged chimney components could impair
safe operation and cause overheating and fi re.
• Support the pipe during construction and check to be
sure inadvertent loading has not dislodged the chimney
section from the fi replace or at any chimney joint.
• Attach a straight chimney section or an offset to the top
of the fi replace.
• Place inner fl ue 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.
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 fl ue.
Figure 8.4 Assembling Chimney Sections
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 fi re.
• Fasten offset/returns to chimney sections. Insert the
screws (provided) through the predrilled holes. Do NOT
penetrate inner fl ue.
• 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).
D. Install Chimney Air Kit
• Required in Canada.
• Follow instructions provided with this accessory.
WARNING! Risk of Fire! You MUST install an attic insulation shield when there is any possibility of insulation or
other combustible material coming into contact with the
chimney.
• DO NOT pack insulation between the chimney and the
attic insulation shield.
• Failure to keep insulation and other materials away from
chimney pipe could cause fi re.
• DO NOT offset chimney inside insulation shield.
Installation of a ceiling fi restop is required
• Refer to Figures 8.6 - 8.8.
• Roll the shield (around the chimney if already installed)
until you have a 3 in. (76 mm) overlap and the three
holes on each side match up (large holes on top).
• Insert three screws into the matching holes to form a
tube.
• Bend three tabs on the bottom of the tube inward to 90°
to maintain chimney air space (refer to Figure 8.6).
• Rest the insulation shield on the ceiling fi restop below.

hold back the insulation can be used.
WARNING! Risk of Fire! Use of cardboard or other
materials that can defl ect under humidity or other envi-
ronmental conditions is not recommended.
• The shield or barrier must be tall enough to extend
above the insulation and prevent blown-in insulation
from spilling into the cavity.
• Maintain specifi ed air spaces around chimney.
• Check instructions and local codes for further details.
• Drive a nail up through roof to mark center of pipe.
• Measure to either side of nail and mark the 14-1/2 in. x
14-1/2 in. (368 mm x 368 mm) opening required.
• Measure opening on the horizontal; actual length may
be larger depending on roof pitch.
• Cut out and frame opening.
• Refer to Chapter 25 of the Uniform Building Code for
roof framing details.
H. Complete Installation
WARNING! Risk of Fire! You MUST maintain 2 in.
(51 mm) air space to insulation and other combustible
materials around the chimney system. Failure to do so
could cause overheating and fi re.

Chase Installations
9
A. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
fi replace 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 building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST
be checked.
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.
Building codes require false ceiling and ceiling fi restops
at each fl oor of the chase or every 10 ft (3.05 m) of clear
space to control spread of fi re.
Walls, ceiling, base plate and cantilever fl oor at the fi rst
level of the chase should be insulated. See Figure 9.1.
Vapor and air infi ltration barriers should be installed in the
chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that
the inside surfaces be sheet rocked and taped (or the use
of an equivalent method) for maximum air tightness.
Gas line holes and other openings should be caulked with
high temperature caulk or stuffed with unfaced fi berglass
insulation. If the fi replace 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.
Three examples of chase applications are shown in Figure 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.
Note: In cooler climates, all chase walls should be insulated.
