GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND UNDERSTAND BEFORE YOUR FIRST FIRE.
1. Use SOLID WOOD only for fuel. It is best to
use dry and well seasoned hardwood. Soft
woods tend to burn very quickly. Solid scrap
construction lumber produces excessive
sparks. DO NOT use treated wood, artificial
wax based logs, charcoal, coal, trash, driftwood or woods that have been dipped in tar,
pitch, pine tar, creosote, etc. Wood products
made with synthetic binders, such as plywood, produce abnormally high temperatures
and sputtering, smoking fires.
2. NEVER use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or “freshen up” a fire in this
fireplace. Keep any flammable liquids a safe
distance from the fireplace.
3. NEVER leave children unattended when
there is a fire burning in the fireplace.
2
4. Always ensure that the air inlet to the
fireplace is free from debris and any other
obstructions that can block the entrance of air.
5. With the fire burning, close the protective
mesh screens to keep sparks and embers INSIDE the firebox.
6. Keep any combustible furniture or decorative objects at least 60" (1524 mm) from the
fireplace opening.
7. Never leave your fireplace unattended while
it is burning.
8. Be careful adding wood fuel to the fire or
handling fireplace tools such as shovels, tongs
or pokers.
9. Never modify or alter your fireplace system
in any way. To do so may create a potential fire
hazard and void the Limited Warranty.
10. The bottom refractory can be cracked by
excessive abuse such as tossing heavy logs
onto the grate or gouging with fireplace tools.
Exercise caution when adding wood to your
fireplace.
11. DO NOT use a fireplace insert or any other
product not specified by the manufacturer for
use with this fireplace.
12. Neither the manufacturer nor the seller
warrants "smoke free" operation nor are they
responsible for inadequate system draft caused
by mechanical systems, general construction
conditions, inadequate chimney heights, adverse wind conditions and/or unusual
environmental factors or conditions beyond
our control.
WARNING: TO AVOID THE RISK OF
DAMAGING FIREPLACE MATERIALS
AND INCREASING THE RISK OF FIRE,
DO NOT USE THE FIREPLACE TO COOK
OR WARM FOOD.
GENERAL INFORMATION
1. The all-steel, multi-wall firebox is the heat
center of the system. It is constructed for safe
clearance to combustibles.
2. The hearth floor and sidewalls of the
firebox are lined with a brick pattern reinforced refractory for the look of authenticity
and to provide safety.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
3. The metal chimney sections extending from
the firebox top to beyond your roof are two
walled and air-cooled. The inner passage, or
flue, provides the exit for smoke and gases.
4. This fireplace does not have a damper.
There is a flue strainer provided at the flue
entrance to keep debris from entering the
chimney. Before you start a fire, the strainer
must be checked to ensure that it is free of
obstructions.
5. Closed screens prevent fire, sparks and
embers from popping out of the firebox while
a fire is burning. Pull screens back when
adding wood to the firebox.
6. Why use a fuel grate? Besides positioning
the firebed properly, it protects the refractory
floor, back and sides of the fireplace. Further,
it ensures a proper flow of combustion air into
and around the firebed. The grate must be
used at all times when burning. Your warranty
may be voided without the use of this grate.
7. This fireplace is not a heater. It is designed
to ensure homeowner comfort by providing
supplemental heat to its immediate area.
FUELS
Never Use Coal in Your Fireplace
Your fireplace system is not designed to be
used with coal derivative products. The combustion process of certain types of coal can
deposit corrosive materials in the fireplace and
chimney system which can lead to premature
product failure. Never use coal as a fuel in this
fireplace system.
Gas Logs
If your fireplace system was installed with a
gas line, you may wish to install one of two
types of gas log sets.
This fireplace has been tested and approved
for use with a decorative gas appliance incorporating an automatic shut-off device and
complying with the Standard for Decorative
Gas Appliances for installation in vented fireplaces, ANSI Z21.60 (1991). Decorative gas
appliances may be installed in these fireplaces.
Installation must be in accordance with the
national Fuel Gas Code, ANSI Z223.1 for compliance with the revised U.L. 127 Standard.
WARNING: THIS FIREPLACE HAS NOT
BEEN TESTED WITH AN UNVENTED GAS
LOG SET. TO REDUCE THE RISK OF
FIRE OR INJURY, DO NOT INSTALL AN
UNVENTED GAS LOG SET INTO THIS
FIREPLACE.
Prior to installing any gas log set, refer to the
fireplace installation instructions for verification of mantle heights and placement of
combustible materials around the firebox opening. Vented gas log sets do not have restrictions
placed upon their BTU rating.
Wood Fuel Pointers
Wood is a wonderful renewable fuel source.
Normally it burns clean, leaving only a minimum of waste ash, provides comforting heat
and can provide a variety of aromas and visual
images.
You will want to know which woods are best for
use. Sometimes you may want a quick, short
fire to offset a morning chill. Soft woods are
preferable in this case. Other times you would
want more slow burning and a uniform heat
output. Hardwoods are preferable for this use.
The amount of heat available from the logs will
be about equal on a weight basis. However,
logs are generally not weighed so the amount
of heat will depend on:
1.
2.
3.
4.
The type of wood used.
How dry it is.
How many logs you put in.
The size of the logs.
The last statement means that one big log
weighing 10 pounds has as much heating potential as 10 pounds of twigs. However, air
cannot get at the solid log to feed the fire so the
solid log will burn slowly. While you would get
the same amount of heat out of either fire, the
smaller the pieces of wood and the more air
space around them, the faster the fire will burn.
DISPOSAL OF ASHES
Ashes should be placed in a metal container
with a tight fitting lid. The closed container of
ashes should be placed on a noncombustible
floor or on the ground, well away from all
combustible materials, pending final disposal.
If the ashes are to be disposed of by burial in
soil or other wise locally dispersed, they should
be retained in the closed container until all
cinders have thoroughly cooled.
SOFTWOOD VS HARDWOOD
Softwoods contain about 15 percent highly
flammable resin which generates creosote soot
in the chimney flue. Burning softwood exclusively may not be as desirable nor as safe as
burning denser hardwoods. Many experienced
fire-builders use small amounts of softwood
kindling and newspaper in conjunction with
starting a fire with split hardwood logs. Here are
some guidelines to remember:
8. Be a knowledgeable wood buyer. There is a
difference in cord sizes. A standard cord stack
of logs is 4 ft. high by 8 ft. long by 4 ft. deep or
the equivalent of this cubic footage, (Figure 1 ).
8'
Standard
Cord of
Wood
4'
1. Softwoods produce fast warming and shorter
fires. Hardwoods burn less vigorously, have
shorter flames and produce steady, glowing
coals.
4'
2. As a general rule, denser woods contain
more potential heat per pound. Most softwoods
offer moderate heat value per pound.
Figure 1
3. Different woods vary widely in flame heights,
flame intensities, smoke characteristics and in
sparking. Most hardwoods do not spark.
A face cord is the same height and length as a
standard cord but the depth is only the length
of the logs (12, 18 or 24 inches). A face cord
can contain as little as 25% of the wood found
in a standard cord.
4. Most freshly cut “green” wood will not burn
well and will smoke. Green wood can be from
10 to 40 percent less efficient than air-dried
seasoned wood.
5. Moisture and resin found inside unseasoned
wood cells will build up pressure under heat
and explode as sparks.
6. Most wood needs to be seasoned 9 to 12
months to reduce the moisture content and
produce good steady fires. When moisture
content is reduced from 60 to 20%, the gain in
heat potential is nearly 7%.
7. Proper storage of wood, especially during
seasoning, is essential. We recommend that
you:
a. Never store wood on the ground. This will
cause rotting and insect infiltration. Raise wood
on flat rock or scrap wood.
b. Stack wood loosely to allow air circulation.
c. Store wood where it will not be excessively
exposed to weather, such as under a tarp or
under a roof.
If you buy by the ton, remember that wood
becomes lighter as it dries. When buying green
or wet wood, ask for some extra poundage to
allow for the extra water you will be getting.
9. When comparing woods of the same moisture content and same species, we find most
woods have approximately the same heating
potential per pound.
However, most wood is sold by volume, not by
weight. To determine the best heating source,
look at the density of various wood types.
(Density is the weight for a given size.) The
higher the density, the more potential heat
output. A standard cord has a volume of 128
cubic feet. This figure also includes the air
space between and around the wood. The actual volume in a standard cord is between 60
and 100 cubic feet; depending on how tightly
the wood is packed.
Assuming that you are comparing two standard
cords of different species but the same volume
and moisture content, the denser species will
provide more BTU’s. The table of wood species/
densities reveals more helpful guidelines.
d. Do not stack wood directly against the walls
of your home.

1. Hang the retaining brackets on the outermost screws inside the firebox at the back,
near the flue inlet.
2. Place one side of the flue strainer, wedged
between the front screws and the top, inside
the firebox.
3. With the aid of a flat screw driver, push
upwards on the opposite end of the flue strainer
against the retainer brackets, (one at a time)
until it snaps to its locking position.
AIR INLET
DAMPER
Note: This appliance does not have a damper.
A flue strainer has been provided to prevent
any debris from entering into the chimney.
FLUE STRAINER
The flue strainer is a wire cloth attached to the
flue entrance to prevent debris from entering
the chimney.
This appliance requires the installation of an
air inlet for proper operation.
The fireplace draws air into the chimney and
firebox chambers through the air inlet to cool
the firebox during operation.
It is important to inspect the air inlet and free
it from any obstruction before operating the
fireplace (see Figure 3 ).
WARNING: DO NOT OPERATE THE FIREPLACE UNLESS A COMPLETE AIR INLET
SYSTEM HAS BEEN INSTALLED.

Any Obstructions
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
All fireboxes contain a furnace refractory floor,
sides and back. These refractories are reinforced with steel, but can be broken by improper
use. Dropping logs on the bottom refractory
and building fires directly against the refractories can cause premature burnout of these
components. It may easily be repaired or replaced at costs far below repair and maintenance
for masonry fireplaces.
Proper care and “burn-in” of the firebox will
prolong the period of enjoyment without extensive maintenance. For the first few uses, build
small fires – not roaring infernos. The materials
used in the refractories contain and absorb moisture. It is important to “cure” the refractories by
building only modest fires. Under normal usage,
it is expected that hairline cracks will appear in the
refractory surface. These hairline cracks do not
affect the safe operation of the fireplace.
STARTING A FIRE
Note: Caution must be observed when operating this fireplace under windy conditions. Do
Not burn large fires, as flames may be drawn
out of the firebox. If this occurs, close the glass
doors immediately. If not equipped with doors,
extinguish the fire or keep it to a minimum if
safe. The screens must be closed at all times
while in operation, except when feeding the fire.
1. To start a fire in the fireplace properly, first
check that the flue strainer is clear and the air
inlet is unobstructed.
2. The grate in the firebox should be centered
on or over the bottom hearth so your fire can
breath properly. Crumble and twist plenty of
newspapers UNDER the grate and criss-cross
some small dry kindling sticks on top of the
paper or on the bottom of the grate.
3. Build a pyramid of three split logs (split will
start much faster). Arrange the uneven wood to
provide plenty of air space between.
4. When lighting your fire, a little smoke may
escape – more likely if the chimney is cold. To
correct this, hold a lighted newspaper up inside
the firebox near the chimney opening. This will
turn around any downdraft and clear the flue of
cold air. As your log fire burns below, the
updraft will improve as the chimney heats up.
5. Now, light the paper at both sides of the
firebox.
6. Close the screens to prevent the escape of
sparks and embers.
Care and Cleaning of Your Glass Doors
Never clean the glass when the doors are hot.
Do not use ammonia or ammonia based glass
or household cleaner to clean the glass or the
door frame. An ammonia based cleaner will
damage the finish of the glass door.
Clean the glass doors by wiping with a damp towel
followed by a clean dry towel to remove streaks.
Remove stubborn stains from the glass with a
mild soap solution and a towel dampened with
clean water. Dry with a clean dry towel.
• The fire must always be confined within the
boundaries of the fuel grate.
• The fireplace screens must always be closed
whenever the fireplace is being used.
• Never slam the glass door since it could cause
the glass to break.
GLASS DOOR OPERATING SAFETY
PRECAUTIONS AND INSTRUCTIONS
• Do not build excessively large or hot fires —
scorching or discoloring of the plated brass
trim may occur.
These fireplaces may be equipped with glass
doors. Refer to the end of this document for a
listing of the glass doors approved for use with
these fireplaces.
• Extreme temperature changes can cause glass
breakage — do not build a hot fire and close the
glass doors if the doors are cold.
WARNING: IF YOUR FIREPLACE IS
EQUIPPED WITH GLASS DOORS, IT
SHOULD BE OPERATED WITH THE DOORS
FULLY OPEN OR FULLY CLOSED. IF THE
DOORS ARE LEFT PARTIALLY OPEN, GAS
AND FLAMES MAY BE DRAWN OUT OF
THE OPENING, CREATING RISKS OF BOTH
FIRE AND SMOKE. SEE FIGURE 4 FOR
PROPER OPERATING CONDITIONS.
Glass Doors
Fully Open or
Fully Closed
(Bi-Fold Doors)
Figure 4
CAUTION: IF A SMOKING CONDITION EXISTS, GLASS DOORS SHOULD BE CLOSED
DURING FIREPLACE OPERATION.
• If the tempered glass pane becomes scratched
or chipped, it creates a weakness in the glass
which can cause the glass to break when heated.
Replace the pane of glass by contacting your
nearest dealer.
CAUTION: GLASS AND METAL FRAMES
GET HOT — ALWAYS USE HANDLES TO
OPEN AND CLOSE THE DOORS.
WARNING: BE AWARE THAT SAFETY
GLASS IS UNPREDICTABLE WHEN HOT
AND MAY BREAK, EXPELLING HOT GLASS
INTO THE ROOM. ADVISE ALL FAMILY
MEMBERS TO REMAIN WELL AWAY
FROM THE FIREPLACE WHEN OPERATING WITH DOORS CLOSED TO AVOID
ANY POSSIBLE PERSONAL INJURY.
IMPORTANT: Plated polished brass glass
doors may have a plastic covering over all
brass pieces for protection during shipping
and handling. The plastic covering should be
removed before installation of the glass doors.
Under the plastic covering is a protective
lacquer coating which should not be removed.
In some instances, if it is removed, irreversible damage to the brass finish could occur.
Refer to the following for specific information
on plated polished brass.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
IMPORTANT: The lacquer coating on the polished brass glass doors and trim pieces can
be damaged or removed causing corrosion
and/or tarnish. Do not remove the protective
lacquer coating from plated polished doors
and trim. To help protect the finish; use a
non-acidic wax and avoid the over-spray of
acidic/alkali based glass cleaners on the
brass pieces. Please understand that the
heat of the fire will cause the protective
lacquer finish to slightly change to a light
caramel color. Do not be alarmed as this is
a normal occurrence.
MAINTENANCE GUIDELINES
Your fireplace is designed to operate troublefree with minimum maintenance. However, like
any fine appliance, it deserves and requires
some housekeeping attention.
Your fireplace will perform better – and certainly look more attractive to family and friends
– if it is cleaned before each use. Before the first
seasonal use in Autumn and after the last fire in
Spring, it is important to inspect the fireplace
system carefully. We recommend at least two
complete fireplace inspections a year.
Before Each Use
1. Clean the firebox of excessive ashes. Some
owners prefer to leave a small layer to insulate
the cold refractory below the grate which helps
fire starting.
This fireplace has a factory supplied grate attached, it is permissible to remove the grate for
cleaning; however, the grate must be re-attached to the fireplace before the next burn.
2. Keep the fireplace screens clean so combustion air flows freely.
3. Spot check the brick-like refractory for small
cracks. Heat from the fire expands it slightly.
When it cools, it contracts.
Refractories should be replaced when:
1. The crack opens more than ¹⁄₄" (19 mm).
2. Pitting in the surface is extensive and pits
become deeper than ³⁄₁₆" (4.76 mm).
3. Any piece of refractory larger than 2" (51 mm)
in radius and ³⁄₁₆" deep becomes dislodged.
If conditions 1, 2 or 3 occur, the refractory
should be replaced.
5
TWICE A YEAR CHECK-UP
Normally, twice a year, you should inspect
your fireplace following this list:
1. Inspect the opening in your chimney top
and remove any debris that could clog it. The
cap is usually held in place by four (4) screws,
which remove easily for checking or cleaning
the full length of the flue from above. Remove
the chimney top while wearing gloves to guard
against any sharp metal edges.
2. Inspect the entire flue from the top down for
obstructions such as birds nests, leaves, etc.
This may be done by using a flexible handled
chimney cleaning brush. If the chimney contains offset/return elbows; a soft brush cleaning
from the top down to any elbow and then from
the firebox up to the offset/return section is the
proper method. The beam from a powerful
flashlight will help in this inspection, (removal
of the flue strainer may be needed).
CLEANOUT PANEL (DOOR SUPPORT
FRAME)
The Cleanout Panel provides an outlet for
water that may enter the fireplace during raining or melting snow. Therefore it is important
to keep it clear from ashes and debris.
Remove the Cleanout Panel by removing the
screw at each end and lift (see Figure 5 ).
Check inside and clean if necessary.
Make sure the area is free of any debris and
reattach the panel with the screws previously
removed.
Note: The hearth area can be vacuum cleaned.
Larger debris must be removed manually. It is
recommended to clean the hearth area while
the cleanout panel is removed to make sure
that no ashes will fill the cleanout panel area
upon reattachment.
3. Look up from inside the fireplace to see if
any obstructions are in the lower flue area. If
present, shut the glass doors (if installed) to
seal the firebox and contain any soot that
might fall.
If your fireplace does not have glass doors
installed, a damp sheet covering the fireplace
opening and sealed with masking tape will do.
Then clean the flue from the top down (if an
offset system, clean per Step 2) using a proper
size chimney brush with flexible pole sections.
Don’t open the doors or remove the sheet until
all soot has settled. Vacuum, don’t sweep.
Note: Removal of the flue strainer may be
required to clear any obstructions inside the flue.
4. Check the metal flashing and seals around
your chimney. Seal any cracks or loose nailhead openings to prevent roof leaks.
5. Clean the firebox thoroughly by using a soft
brush or equivalent.
6. Check outside air inlet and free from any
obstructions.
7. Exposed stainless steel face may be cleaned
with a solution of baking soda and water:
Mix a tablespoon of baking soda in a cup of
water and spray on the exposed stainless steel
face. Wipe with a clean cloth.
6
CREOSOTE FORMATION AND 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 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.
The chimney should be inspected at least
twice yearly during the heating season to determine if a creosote build-up has occurred.
If creosote has accumulated, it should be
removed to reduce the risk of a chimney fire.
If creosote build-up is found, do not use chemical chimney cleaners that are poured on a hot
fire. The chemical cleaners can be dangerous
and generally only work on the flue section
nearest the fire, leaving the rest of the flue
unaffected. It is best to take the time to clean
the flue as previously described or have the
chimney professionally cleaned by a qualified
chimney sweep.

WARNING: CONTINUED OVERFIRING
CAN PERMANENTLY DAMAGE YOUR
FIREPLACE SYSTEM. SOME EXAMPLES
OF OVERFIRING ARE:
• BURNING QUANTITIES OF SCRAP
LUMBER, PINE BRANCHES, PAPER OR
CARDBOARD BOXES WHICH EXCEED
THE VOLUME OF THE NORMAL LOG FIRE.
• USE OF ARTIFICIAL WAX BASE LOGS,
TRASH OR OTHER CHEMICALS OR
CHEMICALLY TREATED COMBUSTIBLES.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Note: "Smoke Free" operation is not warranted
nor are we responsible for inadequate system
draft, general construction conditions, inadequate chimney heights, adverse wind conditions and/or unusual environmental factors or
conditions beyond our control.
If you do experience a problem, here are several things to check:
1. Remember – always check to ensure that
the flue strainer and air inlet are clear from
obstructions before lighting a fire!
2. Is your fire too far forward? Move it toward
the back with your poker. Keep the fire well
within the confines of your fuel grate.
3. Keep your fire up on the grate and the refractory below free of excessive ashes. The fire
needs plenty of air movement around the logs.
4. Is a breeze or wind blowing? This can cause
negative pressure and an unwanted downdraft
– and smoking.
5. Is your wood fuel too wet or unseasoned?
Or does it contain some chemical substance
that causes sputtering, smoking and toxic
fumes?
6. Figure 6 illustrates the correct height of
your chimney top. It is unlikely that your installation does not adhere to the installation
instructions. However, if not correct, you
could experience an unusual downdraft. Usually, the best solution is to increase the chimney
height. This may also be necessary if nearby
trees, adjoining roof lines or a hill is causing a
downdraft condition.
