IMPORTANT! GENERAL SAFETY
PRECAUTIONS. READ AND
UNDERSTAND THESE SAFETY
RULES BEFORE YOUR FIRST FIRE.
WARNING
To avoid the risk of damaging
fi replace materials and increasing the risk of fi re, do not use the
fi replace to cook or warm food.
AVERTISSEMENT
Pour éviter le risque
d’endommager les matériaux
du foyer et d’augmenter le
risque d’incendie, n’employez
pas le foyer pour faire cuire ou
réchauffer de la nourriture.

NEVER LEAVE CHILDREN UNATTENDED
WHEN THERE IS A FIRE BURNING IN
THE FIREPLACE.
2. When burning wood, use SOLID NATURAL
DRY WELL-SEASONED WOOD ONLY. Hard-
woods are recommended (soft woods tend
to burn very quickly).
• DO NOT burn treated wood, charcoal, coal,
trash, driftwood, woods dipped in tar, Christmas tree greens, pitch, pine tar, creosote,
chemical chimney cleaners, fl ame colorants,
polystyrene packaging, wood products with
synthetic binders (i.e. plywood). Plywood,
lumber and other misc. materials can produce
abnormally high temperatures, sputtering and
smoking fi res and may contain hazardous
chemicals to treat insects and fungus.
• When using newspapers to start a wood fi re,
remove (and do not burn) the colored comic
or ad sections. The colored inks contain lead
and can produce toxic gases.
• If Artifi cial Logs are burned it is required that
the logs are UL safety listed (see labeling or
documention provided with logs). Read and
follow the log manufacturer's instructions. Do
not treat artifi cial logs (made from sawdust
and wax) the same way you treat real natural
wood logs. Use only one at a time.
• IMPORTANT: Burning unapproved fuels can
produce excessive temperatures, beyond
the design capabilities of the fi replace and
may produce excess sparks or may contain
hazardous chemicals. Burning unapproved
fuels can result in a chimney fi re, a house fi re,
personal injury, death or loss of property.
3. NEVER use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fl uid, NAPHTHA, ENGINE OIL or similar liquids to start
or “freshen up” a fi re in this fi replace. Keep
any fl ammable liquids a safe distance from
the fi replace.
4. Keep the chimney damper open while any
fi re or smoldering embers are present .
5. Use care when selecting window treatments
for windows located near the fi replace. Avoid
using combustible fl owing window treatments
such as curtains on nearby windows that are
of suffi cient length to be blown in front of an
open fl ame when the window is opened.
6. With the fi re burning, close the protective
mesh screens to keep sparks and embers
INSIDE the fi rebox. Closed screens prevent
fi re, sparks and embers from popping out of
the fi rebox while a fi re is burning. Pull screens
back when adding wood to the fi rebox.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
7. Keep any combustible furniture or decorative pillows at least 60" (1524 mm) from the
fi replace opening.
8. Never leave your fi replace unattended while
it is burning.
9. Be careful adding wood fuel to the fi re or
handling fi replace tools such as shovels,
tongs or pokers.
10. Never modify or alter your fi replace system
in any way. To do so may create a potential
fi re hazard and void the Limited Warranty.
11. The bottom refractory can be cracked by
excessive abuse such as tossing heavy logs
onto the grate or gouging with fi replace tools.
Exercise caution when adding wood to your
fi replace.
12. Fireplace Inserts - Contact your dealer or
distributor for a list of Lennox fi replace
inserts approved for installation into your
fi replace. DO NOT install a fi replace insert
from any another manufacturer.
13. If you are using your fi replace as a “decorative appliance,” such as with a permanently
installed gas log set, the fi replace damper
must be permanently fi xed in the open position. Listed “vent-free” gas log sets may be
used with the damper closed.
14. If this unit is installed indoors, always ensure
that an adequate supply of replacement combustion air from the outside of the house is
accessible to the fi re to support normal combustion. Fireplaces consume large volumes
of air during the normal combustion process.
In the event the home is tightly sealed with
modern energy effi cient features, the optional
combustion air kit may not provide all the
air required to support combustion. The
manufacturer is not responsible for any
smoking or related problems that may result
from the lack of adequate combustion air. It
is the responsibility of the builder/contractor
to ensure that adequate combustion air has
been provided for the fi replace.
15. Neither the manufacturer nor the seller
warrants “smoke free” operation nor are
we 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.
16.Always ensure that the air inlet to the fi replace
is free from debris and any other obstructions
that can block the entrance of air.
GENERAL INFORMATION
1. The all-steel, multi-wall fi rebox is the heat
center of the system. It is well insulated for
safe clearance to combustibles.
2. The hearth fl oor and sidewalls of the fi rebox
are lined with a brick pattern reinforced
refractory for the look of authenticity and
to provide safety.
3. The metal chimney sections extending from
the fi rebox top to beyond your roof are two
walled and air-cooled. The inner passage,
or fl ue, provides the exit for smoke and
gases.
4. The fl ue damper is a two position (fully
open or fully closed) mechanism operated
by a handle found at the center top of the
fi replace opening. It must be open when fi re
is present so smoke and gases can escape.
It should be closed only when the fi re is
completely out – keeping room air from
being lost up the fl ue.
5. Closed screens prevent fi re, sparks and
embers from popping out of the fi rebox
while a fi re is burning. Pull screens back
when adding wood to the fi rebox.
6. Why use a fuel grate? Besides positioning
the fi rebed properly, it protects the refractory
fl oor, back and sides of the fi replace. Further,
it ensures a proper fl ow of combustion air into
and around the fi rebed. The grate must be used
at all times when burning. Your warranty may
be voided without the use of this grate.
7. This fi replace 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 fi replace 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 fi replace and
chimney system which can lead to premature
product failure. Never use coal as a fuel in this
fi replace system.
Gas Logs
If your fi replace system was installed with a gas
line, you may wish to install one of two types
of gas log sets.
This fi replace 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 fi replaces, ANSI Z21.60
(latest edition). Decorative gas appliances may
be installed in these fi replaces. Installation
must be in accordance with the National Fuel
Gas Code, ANSI Z223.1 for compliance with
the revised U.L. 127 Standard.
CAUTION
When using a decorative gas
appliance, the fi replace damper
must be set in the fully open
position.
ATTENTION
Si vous utilisez un appareil
décoratif au gaz, le registre de
la cheminée du foyer doit être
ouvert complètement.
WARNING
Unvented Gas Log Sets are
not approved for use with fi replaces installed outdoors. The
materials and components
will deteriorate prematurely if
installed outside. Refer to the
log manufacturer’s literature for
limitations and exceptions.
AVERTISSEMENT
Les ensembles de bûches à gaz
sans conduit d’évacuation ne
sont pas approuves pour l’usage
avec des foyers installes a
l’exterieur. Les materiaux et les
composantes se deterioreront
prematurement si installees
a l’exterieur. Referez-vous a
la litterature du fabricant des
buches pour les limites et les
exceptions.
This fi replace has been tested and approved
to ANSI/IAS/AGA Z21.11.2 for use with an
unvented gas appliance having a maximum
rating of 26,000 BTU and complies with the
Standard for Factory-Built Fireplaces, U.L. 127,
when installed with unvented gas log sets. The
limit may be increased to 40,000 BTU providing that minimum combustible mantel heights
were increased to at least 18 inches when the
fi replace was installed.
Prior to installing any gas log set, (Vented or
Unvented) refer to the fi replace installation
instructions for verifi cation of mantel heights
and placement of combustible materials around
the fi rebox opening.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
IMPORTANT
Never install an unvented gas
log set with a BTU greater than
26,000 if combustible mantel
projections are lower than
18 inches above the fi replace
opening.
ATTENTION
Ne jamais installer un ensemble
de buches a gaz sans conduit
d’evacuation qui genere une
puissance superieure a 26000
si un manteau combustible est
installe plus bas que 18 po. Au
dessus de l’ouverture du foyer.
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 fi re
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. The type of wood used.
2. How dry it is.
3. How many logs you put in.
4. 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 fi re so the solid log
will burn slowly. While you would get the same
amount of heat out of either fi re, the smaller the
pieces of wood and the more air space around
them, the faster the fi re will burn.
3
DISPOSAL OF ASHES
Ashes should be placed in a metal container with
a tight fi tting lid. The closed container of ashes
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 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
fl ammable resin which generates creosote soot
in the chimney fl ue. Burning softwood exclusively may not be as desirable nor as safe as
burning denser hardwoods. Many experienced
fi re-builders use small amounts of softwood
kindling and newspaper in conjunction with
starting a fi re with split hardwood logs. Here
are some guidelines to remember:
1. Softwoods produce fast warming and shorter
fi res. Hardwoods burn less vigorously, have
shorter fl ames and produce steady, glowing
coals.
2. As a general rule, denser woods contain more
potential heat per pound. Most softwoods
offer moderate heat value per pound.
3. Different woods vary widely in fl ame heights,
fl ame intensities, smoke characteristics
and in sparking. Most hardwoods do not
spark.
4. Most freshly cut “green” wood will not burn
well and will smoke. Green wood can be from
10 to 40 percent less effi cient 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 fi res. 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 infi ltration. Raise wood on fl at rock or scrap
wood.
b. Stack wood loosely to allow air circula-
tion.
c. Store wood where it will not be exces-
sively exposed to weather, such as
under a tarp or under a roof.
d. Do not stack wood directly against the
walls of your home.
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).
Standard
Cord of
Wood
8'
4'
4'
Figure 1
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.
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 fi nd 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.

STARTING A FIRE
Note: Caution must be observed when operating this fi replace under windy conditions. Do
Not burn large fi res, as fl ames may be drawn
out of the fi rebox. If this occurs, close the glass
doors immediately. If not equipped with doors,
extinguish the fi re or keep it to a minimum if safe.
The screens must be closed at all times while in
operation, except when feeding the fi re.
1. To start a fi re in a the fi replace properly, fi rst
check the operation of the fl ue damper.
2. To prevent smoking at start-up, if the unit is
installed indoors, close any window located
near the fi replace when fi rst lighting a fi re.
The closed windows may be reopened once
a chimney draft is drawn in the fi replace.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
DAMPER CONTROL
This fi replace is fi tted with a manually controlled
chimney damper. The chimney damper should
be closed when the fi replace is not in use to
prevent cold air from entering the home through
the chimney system.
The damper is controlled through the use of a
control lever located within the fi rebox opening
at the top center just behind the fi rebox lintel
(Figure 2). The control lever snaps into place
at the extreme range of motion, up and back in
the closed position. When pulled forward and
down, the damper is open.
Damper
Closed
Lintel
Figure 2
1. The appliance fl ue damper must always
remain open when operating.
2. The grate in the fi rebox should be centered
on or over the bottom hearth so your fi re
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 fi re, a little smoke may
escape – more likely if the chimney is cold.
To correct this, hold a lighted newspaper up
inside the fi rebox near the chimney opening. This will turn around any downdraft
and clear the fl ue of cold air. As your log
fi re burns below, the updraft will improve
as the chimney heats up.
5. Now, light the paper at both sides of the
fi rebox.
6. Close the screens to prevent the escape of
sparks and embers.

7. For indoor installations, close the damper
only when your fi re is completely out and
ashes are cold. Keep closed when fi replace
is not in use to prevent unnecessary loss of
heated or cooled air.
COMBUSTION AIR INLET
This appliance requires the installation of an
air inlet for proper operation when installed
outdoors.
The fi replace draws air into the chimney and
fi rebox chambers through the air inlet to cool
the fi rebox during operation.
It is important to inspect the air inlet and free
it from any obstruction before operating the
fi replace (see Figure 3).

GLASS DOOR OPERATING SAFETY
PRECAUTIONS AND INSTRUCTIONS
These fi replaces may be equipped with glass
doors. Refer to Pages 10 & 11 for a list of
the glass doors approved for use with these
fi replaces.
WARNING
If your fi replace 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 fl ames
may be drawn out of the opening, creating risks of both fi re
and smoke. Refer to Figure 4 for
proper operating conditions.
AVERTISSEMENT

CAUTION
If a smoking condition exists,
glass doors should be closed
during fi replace operation.
Smoke spillage often occurs when a fi re is fi rst
started, until the fi replace and the chimney has
had the opportunity to “come up to temperature”
and to begin to function normally. If smoke
spillage problems persist, a window may be
opened just a crack to allow the proper fl ow of
combustion air to the fi replace.
Air Gate Operation Instructions
(Indoor Installations Only)
If an Air Gate Kit has been installed (approved
for indoor installations only), operate it as
follows:
ATTENTION
Si vous apercevez de la fumee
qui se degage du foyer, fermez
les portes de verre.
IMPORTANT
See Page 7 for care and clean-
ing instructions for your glass
doors.
ATTENTION
Voir la Page 7 pour les instructions de nettoyage des portes
de verre.
COMBUSTION AIR
A proper amount of combustion air is important
for your fi replace. Fireplaces consume large
amounts of oxygen. It is important to allow
an adequate supply of air.
If the fi replace is not equipped with an outside
air kit, it may not obtain suffi cient amounts
of combustion air from inside the house or
structure in which it is installed. Therefore, the
fi re may draw from an outside air source and
pull air in through the chimney. This may cause
smoke spillage into the room.
If your fi replace is equipped with an outside
combustion air kit, keep it open at all times
when fi re is burning and close when fi re is out
to prevent cold air intrusion.
Combustion Air Control
All indoor installations must have an optional
OAKG Outside Air Kit Gate installed when an
Outside Air Kit is installed.
The actuator for combustion air must not be
operated unless the complete system has been
installed. See Figure 5.
If you have reason to believe that you do not
have a complete outside combustion system,
contact your distributor to have your fi replace
inspected for the presence of the complete
system before you use the combustion air
actuator. DO NOT assume that you have this
system in place because you have an actuating
lever present on your fi replace front face.
WARNING
Do not operate the combustion
air gate actuator unless a complete outside combustion air
vent system has been installed
with your Fireplace.
AVERTISSEMENT
Ne faites pas marcher l’actuateur

The Outside Air Kit Gates are required
when an Outside Air Kit is installed on
all indoor installations only. They are
not approved for use on oudoor installations.

Figure 5
To operate, push the end of the actuator arm
to the left as shown in Figure 5, until it "pops"
free of its "locked" position. Pull the actuator
forward to open the combustion air door, and
push it back to close. To "lock" the combustion
air door closed, ensure the actuator is pushed
all the way back then push the end of the actuators to the right until the step in the actuator
moves behind the appliance front face within
the slotted opening.
Operate the actuator through several cycles
including the "lock" position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the locked position.
MAINTENANCE GUIDELINES
Your fi replace is designed to operate trouble-free
with minimum maintenance. However, like any
fi ne appliance, it deserves and requires some
housekeeping attention.
You r fi replace will perform better – and certainly
look more attractive to family and friends – if
it is cleaned before each use. Before the fi rst
seasonal use in Autumn and after the last fi re
in Spring, it is important to inspect the fi replace
system carefully. We recommend at least two
complete fi replace inspections a year.
6
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Before Each Use
1. Clean the fi rebox of excessive ashes. Some
owners prefer to leave a small layer to insulate
the cold refractory below the grate which
helps fi re starting.
This fi replace has a factory supplied grate
attached, it is permissible to remove the
grate for cleaning; however, the grate must
be re-attached to the fi replace before the
next burn.
2. Keep the fi replace screens clean so combus-
tion air fl ows freely.
3. Spot check the brick-like refractory for small
cracks. Heat from the fi re expands it slightly.
When it cools, it contracts.
TWICE A YEAR CHECK-UP
Normally, twice a year, you should inspect your
fi replace 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 fl ue from above. Remove
the chimney top while wearing gloves to
guard against any sharp metal edges.
2. Inspect the entire fl ue from the top down
for obstructions such as birds nests, leaves,
etc. This may be done by using a fl exible
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 fi rebox up to the
offset/return section is the proper method.
The beam from a powerful fl ashlight will help
in this inspection.
3. Look up from inside the fi replace (damper
open) to see any obstructions in the lower
fl ue area. If present, shut the damper and
glass doors (if installed) to seal the fi rebox
and contain any soot that might fall.
4. Check the metal fl ashing and seals around
your chimney. Seal any cracks or loose
nailhead openings to prevent roof leaks.
5. Clean the fi rebox 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. For
tough stains like smoke and soot stains, use
lubricant oil and steel wool (common spray
lubricants found where automotive supplies
are sold, work well).
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 fi nish 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.
• Never slam the glass door since it could
cause the glass to break.
• Extreme temperature changes can cause
glass breakage — do not build a hot fi re
and close the glass doors if the doors are
cold.
• 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.
If your fi replace does not have glass doors
installed, a damp sheet covering the fi replace
opening and sealed with masking tape will do.
Then clean the fl ue from the top down (if an
offset system, clean per Step 2) using a proper
size chimney brush with fl exible pole sections.
Don’t open the doors or remove the sheet until

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 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.
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 fi re.
If creosote build-up is found, do not use chemical chimney cleaners that are poured on a hot
fi re. The chemical cleaners can be dangerous
and generally only work on the fl ue section
nearest the fi re, leaving the rest of the fl ue
unaffected. It is best to take the time to clean
the fl ue as previously described or have the
chimney professionally cleaned by a qualifi ed
chimney sweep.
REFRACTORIES
All fi reboxes contain a furnace refractory fl oor,
sides and back. These refractories are reinforced
with steel, but can be broken by improper use.
Dropping logs on the bottom refractory and
building fi res 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 fi replaces.
Proper care and “burn-in” of the fi rebox will
prolong the period of enjoyment without extensive maintenance. For the fi rst few uses,
build small fi res – not roaring infernos. The
materials used in the refractories contain and
absorb moisture. It is important to “cure” the
refractories by building only modest fi res. 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 fi replace.
Refractories should be replaced when:
1. The crack opens more than 1/4" (6.4 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.
STAINLESS STEEL OUTDOOR WEATHER
COVER
An optional Stainless Steel Outdoor Weather
Cover can be purchased to provide additional
protection against leaves and other objects
that wind can carry which can accumulate
inside your fi replace or damage your fi replace
Glass Doors. Complete instructions for use are
provided with the cover.
OVERFIRING
• The fi re must always be confi ned within the
boundaries of the fuel grate.
• Do not build excessively large or hot fi res.
• Extreme temperature changes can cause
glass breakage — do not build a hot fi re and
close the glass doors if the doors are cold.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
WARNING
Continued overfi ring can permanently damage your fi replace
system. Some examples of
overfi ring are:
• Burning quantities of scrap
lumber, pine branches, paper or
cardboard boxes which exceed
the volume of the normal log
fi re.
• Burning trash, chemicals or
chemically treated combustibles.
AVERTISSEMENT
Si vous surchauffez continuellement votre foyer, vous pourriez l’endommager de façon
permanente. Voici quelques
exemples:
• Vous brûlez des déchets,
du bois de construction, des
branches de pins, du papier,
des boîtes de carton qui excèdent le volume de feu de bois
normal du foyer. Vous risquez
sérieusement d’endommager
votre système.
• Vous brûlez des substances
telles que : enduit protecteur
pour le bois, papier métallique,
charbon, plastique, rebuts,
souffre ou huile vous pourriez
gravement endommager votre
foyer. Ne brûlez que du bois
non-traité.
TROUBLESHOOTING
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 your
fl ue damper is in the open position before
lighting a fi re!
2. When lighting your fi re, a little smoke may
escape into the room – more likely if the
chimney is cold. To correct this, hold a
lighted newspaper up inside the fi rebox near
the open fl ue damper. This will turn around
any downdraft and clear the fl ue of cold air.
As your log fi re burns below, the updraft will
improve as the chimney heats up.
3. Is your fi re too far forward? Move it toward
the back with your poker. Keep the fi re well
within the confi nes of your fuel grate.
4. Keep your fi re up on the grate and the re-
fractory below free of excessive ashes. The
fi re needs plenty of air movement around
the logs.
5. In indoor installations, if smoking occurs an
hour or two after lighting the fi re, perhaps
your well-insulated house is too airtight
and there is scarcely any way for replacement air to enter and feed the fi re. Check
to see if your outside combustion air kit,
if installed, is open (see Figure 3). Check
outside to ensure no obstructions are in
front of exterior air entry. Open a window
slightly, open doors to one or two rooms
and see if this stops the smoking.
6. Is a vent fan, exhaust hood or central heat-
ing/cooling system stealing combustion air
from your fi replace? If their volume is high
enough, this can cause negative pressure
and an unwanted downdraft – and smoking.
7. Is your wood fuel too wet or unseasoned?
Or does it contain some chemical substance
that causes sputtering, smoking and toxic
fumes?
8. Is a breeze or wind blowing? This can
cause negative pressure and an unwanted
downdraft – and smoking.
9. Figure 6 illustrates the correct height of
your chimney top for indoor installations.
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.
10. Remember, your fi replace has been de-
signed as a supplemental heating device
only, it is not intended to heat your entire
home.
