environmental factors or conditions beyond
our control.
GENERAL INFORMATION
1. The all-steel, multi-wall firebox is the heat
center of the system. It is well insulated for
safe clearance to combustibles.
2. The hearth floor and sidewalls of the firebox
are lined with a brick pattern reinforced refrac-
tory for the look of authenticity and to provide
safety.
3. Themetal 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.Theflue damper is a twoposition(fullyopen
or fully closed) mechanism operated by a
handle found at the center top of the fireplace
opening. It must be open when fire is present
so smoke and gases can escape. It should be
closed ONLY when the fire is completely out –
keeping room air from being lost up the flue.
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.Remember, your fireplaceis not intendedto
heat your entire home.
FUELS
Never Use Coal in Your Fireplace
Your fireplace system is not designed to be
used with coal derivative products. The com-
bustion process of certain types of coal can
deposit corrosive materials in the fireplace
and chimney system which can lead to prema-
ture product failure. Never use coal as a fuel in
this fireplace system.
3.Keepthechimneydamperopenwhileanyfire
or smoldering embers are present .
4. Never block or restrict the room air intake
grille across the bottom front or the warm air
outlet grille across the top front of the fireplace.
5.Usecarewhen selecting window treatments
for windows located near the fireplace. Avoid
usingcombustible flowingwindowtreatments
suchas curtains on nearby windows that are of
sufficientlengthtobeblown in front of an open
flame when the window is opened.
6. With the fire burning, close the protective
mesh screens to keep sparks and embers
INSIDE the firebox.
7. Keep any combustible furniture or decora-
tive pillows at least 36" (914 mm) from the
fireplace opening.
8. Never leave your fireplace unattended while
it is burning.
9. Be careful adding wood fuel to the fire or
handlingfireplace toolssuchasshovels, tongs
or pokers.
10. Never modify or alter your fireplace sys-
teminany way. Todo so may createa potential
fire hazard and void the Limited Warranty.
11. The bottom refractory can be cracked by
excessiveabusesuchas tossingheavylogsonto
the grate or gouging with fireplace tools. Exer-
cisecautionwhenaddingwoodtoyourfireplace.
12. DO NOT use a fireplace insert or any other
product not specified by the manufacturer for
use with this fireplace.
13.If you are using your fireplaceasa“decorative
appliance,” such as with a permanently installed
gas log set, the fireplace damper must be perma-
nentlyfixedintheopenposition.Listed“vent-free”
gaslog sets maybe used withthe damper closed.
14. Always ensure that an adequate supply of
replacement combustion air from the outside
of the house is accessible to the fire 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 efficient features, the op-
tionalcombustion airkit may not provide all the
airrequiredtosupportcombustion. Neitherthe
manufacturer nor the seller are responsible for
any smoking or related problems that may
result from the lack of adequate combustion
air. It is the responsibility of the builder/con-
tractor to ensure that adequate combustion air
has been provided for the fireplace.
GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND UNDER-
STANDBEFOREYOURFIRSTFIRE.
1. Use SOLID WOOD only for fuel. It is best to
use dry and well seasoned hardwood. Soft
woods tend to burn very quickly. DO NOT use
treated wood, 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, pro-
duce abnormally high temperatures and
sputtering, smoking fires.
Never burn treated construction lumber or
scraps. Thesewoods burnexcessively hot and
may contain chemicals used to treat insects
and fungus. When burned, these chemicals
can pose a significant hazard.
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.
WARNING: DO NOT POKE OR STIR PRO-
CESSED SOLID FUEL LOGS WHILE THEY
ARE BURNING. ONLY USE LOGS THAT
HAVE BEEN EVALUATED FOR APPLICA-
TION IN THE FIREPLACE AND REFER TO
ALLFIRELOGWARNINGSANDCAUTIONS
MARKED ON THE PACKAGING.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 po-
tential 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.
Iftheashesaretobedisposedofbyburialinsoil
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
flammableresinwhichgeneratescreosotesoot
in the chimney flue. Burning softwood exclu-
sively 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
startingafirewithsplithardwoodlogs.Hereare
some guidelines to remember:
1.Softwoodsproducefastwarmingandshorter
fires. Hardwoods burn less vigorously, have
shorter flames and produce steady, glowing
coals.
2. As a general rule, denser woods contain
morepotentialheatperpound.Mostsoftwoods
offer moderate heat value per pound.
3.Different woods vary widelyinflameheights,
flame 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 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.
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 mois-
ture content and same species, we find most
woods have approximately the same heating
potential per pound.

their BTU rating.
Wood Fuel Pointers
Wood is a wonderful renewable fuel source.
Normally it burns clean, leaving only a mini-
mum of waste ash, provides comforting heat
and can provide a variety of aromas and visual
images.
Youwill want toknowwhich woods arebest 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:
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
causerottingandinsectinfiltration.Raisewood
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.
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 ).

The appliance flue damper must always re-
main open when operating.
3. 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.

STARTING A FIRE
1. Tostart a fire in athe fireplaceproperly, first
check the operation of the flue damper.
2. To prevent smoking at start-up, close any
window located near the fireplace when first
lighting a fire. The closed windows may be
reopened once a chimney draft is drawn in the
fireplace.
DAMPER CONTROL
This fireplace is fitted with a manually con-
trolledchimneydamper. Thechimneydamper
should be closed when the fireplace 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 firebox open-
ing at the top center just behind the firebox
lintel ( Figure 2 ).
Push back and up (away from the front of the
fireplace) to lock the damper blade in the
OPEN position. To lock the damper in the
CLOSED position, the damper handle needs
to be pulled down and forward (towards the
front of the fireplace).
4. Build a pyramid of three split logs (split will
startmuch faster). Arrange the uneven wood to
provide plenty of air space between.
5. Now, light the paper at both sides of the
firebox.
6. Close the screens to prevent the escape of
sparks and embers.
7. Close the damper only when your fire is
completelyout andashes are cold. Keep closed
whenfireplaceisnot in use topreventunneces-
sary loss of heated or cooled air.
GLASS DOOR OPERATING SAFETY
PRECAUTIONS AND INSTRUCTIONS
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.
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 ac-
tual volume in a standard cord is between 60
and 100 cubic feet; depending on how tightly
the wood is packed.
Assumingthatyouarecomparingtwostandard
cords of different species but the same volume
and moisture content, the denser species will

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
removedbeforeinstallationoftheglassdoors.
Under the plastic covering is a protective
lacquercoatingwhichshouldnotberemoved.
In some instances, if it is removed, irrevers-
ible damage to the brass finish could occur.
Referto thefollowing forspecific information
on plated polished brass.
IMPORTANT: The lacquer coating on the pol-
ished 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 lac-
querfinishtoslightlychangetoalightcaramel

occurrence.
COMBUSTION AIR
Aproperamountofcombustionairisimportant
for your fireplace. Fireplaces consume large
amounts of oxygen.
It is important to allow an adequate supply of
air. If the fireplace is not equipped with an
outside air kit, it may not obtain sufficient
amounts of combustion air from inside the
house or structure in which it is installed.
Therefore,thefiremaydrawfroman outside air
sourceandpullairinthroughthechimney. This
may cause smoke spillage into the room.
Smoke spillage often occurs when a fire is first
started, until the fireplace and the chimney has
had the opportunity to “come up to tempera-
ture” and to begin to function normally. If
smoke spillage problems persist, a window
may be opened just a crack to allow the proper
flow of combustion air to the fireplace.
If your fireplace is equipped with an outside
combustion air kit, keep it open at all times
when fire is burning and close when fire is out
to prevent cold air intrusion.
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 slamthe glass door since it could cause
the glass to break.
• Do not build excessively large or hot fires —
scorching or discoloring of the plated brass
trim may occur.
•Extremetemperaturechangescancauseglass

OPEN AND CLOSE THE DOORS.
Combustion Air Control
The actuator for combustion air system is
standard on all fireplaces but must not be
operated if the complete system is not in-
stalled. See Figure 4 and refer to Figure 2 .
On this Lennox Elite Series fireplace, the con-
trol lever has been pre-installed. A cover plate
has been mounted over this control lever only
if the outside air kit has not been attached. The
control lever is located on the left hand or
closed side of the fireplace behind the screen.
To open the air damper, pull the lever all the
way out. To close, push the lever all the way in.
REFRACTORIES
All fireboxes contain a furnace refractory floor,
sides and back. These refractories are rein-
forcedwithsteel,butcanbebrokenbyimproper
use. Dropping logs on the bottom refractory
and building fires directly against the refracto-
ries can cause premature burnout of these
components. It may easily be repaired or re-
placedatcostsfarbelowrepairandmaintenance

6NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 creo-
sote 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 de-
termine if a creosote build-up has occurred.
If creosote has accumulated, it should be
removed to reduce the risk of a chimney fire.
Ifcreosotebuild-upisfound,donot usechemi-
cal 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.
TROUBLESHOOTING
No Smoking Allowed
Your new fireplace is designed not to smoke if
properly installed and operated per our in-
structions. If you do experience a problem,
here are several things to check:
1. Remember – always check to ensure your
flue damper is in the open position before
lighting a fire!
2. When lighting your fire, 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 firebox near the open
flue damper. This will turn around any down-
draft and clear the flue of cold air. As your log
fire burns below, the updraft will improve as
the chimney heats up.
3. 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.
4. 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.
Proper care and “burn-in” of the firebox will
prolong the period of enjoyment without exten-
sive maintenance. For the first few uses, build
small fires – not roaring infernos. The materials
usedintherefractoriescontainandabsorbmois-
ture. It is important to “cure” the refractories by
buildingonlymodest fires. Under normalusage,
it is expected that hairline cracks will appear in
the refractory surface. These hairline cracks do
not affect the safe operation of the fireplace.
MAINTENANCE GUIDELINES
Your fireplace is designed to operate trouble-
freewith minimum maintenance.However, like
any fine appliance, it deserves and requires
some housekeeping attention.
Your fireplace will perform better – and cer-
tainly look more attractive to family and friends
–if it iscleaned before each use. Beforethe 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 at-
tached, it is permissible to remove the grate for
cleaning; however, the grate must be re-at-
tached to the fireplace before the next burn.
2. Keep the fireplace screens clean so combus-
tion 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 dis-
lodged.
If conditions 1, 2 or 3 occur, the refractory
should be replaced.
TWICE A YEAR CHECK-UP
Normally,twice a year,you should inspectyour
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 con-
tainsoffset/returnelbows;asoftbrushcleaning
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.
3. Look up from inside the fireplace (damper
open) to see any obstructions in the lower flue
area. If present, shut the damper and glass
doors (if installed) to seal the firebox and con-
tain any soot that might fall.
If your do not have glass doors installed, a
damp sheet covering the fireplace opening and
sealedwithmaskingtapewilldo.Thencleanthe
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.
4. Check the metal flashing and seals around
your chimney. Seal any cracks or loose nail-
head openings to prevent roof leaks.
5. Clean the firebox thoroughly by using a soft
brush or equivalent.
WARNING: CONTINUED OVER FIRING
CAN PERMANENTLY DAMAGE YOUR
FIREPLACE SYSTEM. SOME EXAMPLES
OF OVERFIRING ARE:
• BURNING QUANTITIES OF SCRAP
LUMBER,PINEBRANCHES,PAPER OR
CARDBOARD BOXES WHICH EXCEED
THE VOLUME OF THE NORMAL LOG
FIRE.
• BURNING TRASH, CHEMICALS OR
CHEMICALLY TREATED COMBUS-
TIBLES.
