D. Grate
This fireplace is designed to be used with the grate sup-
plied with this unit or one approved by HHT. The grate will
deteriorate over time and will need occasional replacement.
WARNING! Risk of Fire! Use only the factory-supplied
integral grate.
• Keeps logs in place.
• Allows proper air circulation around the fire.
E. Firescreen
The firescreen is provided to control sparks. Keep it closed
when the fireplace 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 fireplace) during operation of the fireplace.
• Before lighting the fireplace, verify fully open position by
looking up from the inside of the 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.
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.
• (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.
• 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.
• 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.
• 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.
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 flammable vapors and liquids clear 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.
Keep all flammable liquids well away from the fireplace while
it is in use. Combustible materials may ignite.
B. Seasoned Wood
Properly seasoned wood is important for successful opera-
tion of your fireplace. Most woodburning fireplace problems
are caused by burning wet, unseasoned wood.
Seasoned firewood 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 fireplace 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.
CAUTION! Odors and vapors released during initial op-
eration may be irritating to sensitive individuals. Open
windows for air circulation.
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.
NOTICE: Do not substitute for HHT mortar. Other materials
may stain the molded brick panels.

M. Wood Fuel
Hardwood vs Softwood
Your fireplace performance depends on the quality of the
firewood 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 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.
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.
WARNING! Risk of Fire!
• DO NOT burn wet or green wood.
• Wet, unseasoned wood can cause accumulation of
creosote.
Moisture
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.
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.
WARNING! Fire Risk! DO NOT store wood:
• in front of the fireplace.
• in space required for loading or ash removal.
Soft woods Hard woods
• Douglas Fir • Oak
• Pine • Maple
• Spruce • Apple
• Cedar • Birch
• Poplar
• Aspen
• Alder
Processed Solid Fuel Firelogs
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.
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.

3 Maintainance and Service
A. Disposal of Ashes
Frequency: When they reach bottom of grate
By: Homeowner
B. Chimney Inspection/Cleaning
Frequency: At least twice a year during heating season or
as recommended by a certified chimney sweep
By: Certified chimney sweep
Figure 3.1 Chimney & Termination Cap Cleaning
WARNING! Risk of Fire! Ashes could contain hot embers.
• 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.
• 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.
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 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.

from Hearth & Homes Technologies Inc.
WARNING! Risk of Fire! Inspect fireplace molded brick
panel. Crumbling, deteriorated molded brick panel can al-
low overheating of surrounding materials.
E. Glass Cleaning
Frequency: As desired
By: Homeowner
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 fireplace glass cleaner (consult with
your dealer)
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
Expansion and contraction will cause minor cracking of the
molded brick panel. This is normal. The panel 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 a panel,
• Large pieces of panel fall out.
NOTICE: Do not substitute for HHT mortar. Other materials
may stain the molded brick panels.

4 Troubleshooting Guide
Start Fire Problems Possible Cause Solution
Can’t get fire started
Excessive smoke or spillage
Burns too slowly
Smolders, sizzles
Not enough kindling/paper or no
kindling/paper
Use dry kindling, more paper. Arrange kindling & wood for
air movement.
Damper closed/not fully open Open damper.
Not enough air for fire to ignite Check for restricted cap/shroud.
Check for flue blockage.
Pre-warm flue before starting fire (refer to starting fire
section).
Check for adequate vent height (refer to chimney assembly
section).
Open window below the fireplace towards the wind.
Open outside air doors.
Wood condition is too wet, too large Use dry, seasoned wood (refer to wood fuel section).
Bed of coals not established before
adding wood
Start with paper & kindling to establish bed of coals (refer to
starting fire section).
Flue blockage such as birds’ nests or
leaves in termination cap
Have chimney inspected for creosote and cleaned by a
certified chimney sweep.
Down draft or negative pressure
Competition with exhaust devices
Do not use exhaust fans during start-up (refer to negative
pressure section).
Open window below the fireplace towards the wind.
Fire burns too fast Extremely dry or soft wood Mix in hardwood.
Mix in less seasoned wood after fire is established (refer to
wood fuel section).
No glass doors Add glass doors to slow down air flow.
Overdrafting Check for correct vent height; too much vertical height
creates overdrafting.
Check location of vent termination (refer to chimney
assembly section).

B. Design and Installation Considerations
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.
Considerations for successful draft include:
• Preventing negative pressure
• Location of fireplace and chimney
Before installing, determine the following:
• 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.
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:
• 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:
• 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
• Basement installations should be avoided
WARNING! Risk of Asphyxiation! Negative pressure can
cause spillage of combustion fumes and soot. Fire must
draft properly for safe operation.
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.
NOTICE: Hearth & Home Technologies Inc. recommends the
use of direct vent appliances in basements.
D. Negative Pressure
C. Draft
NOTICE: The fireplace provides some outside air for
combustion. Other methods may be necessary if more air
is required.

• Not the highest point of the roof
• Wind loading possible
Multi-level Roofs
Windward
Leeward
Recommended Location:
• Above peak
Recommended:
• Insulated exterior chase
in cooler climates
Recommended Location:
• Above peak
• Inside heated space
Location NOT recommended:
• Too close to tree
• Below adjacent structure
• Lower roof line
• Avoid outside wall
Marginal Location:
• Wind loading possible
Figure 5.1 Recommended Chimney Locations
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.
E. Locating your Fireplace & Chimney
NOTICE: Locating the fireplace in an area of considerable
air movement can cause intermittent smoke spillage from
fireplace. Do not locate fireplace near
• frequently open doors
• central heat outlets or returns
DO NOT install in a basement.
