GENERAL SAFETY PRECAUTIONS
IMPORTANT! READ AND
UNDERSTAND BEFORE
BUILDING 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. 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, produce
abnormally high temperatures and sputtering,
smoking fires.
WARNING
Do not poke or stir processed
solid fuel logs while they are
burning. Only use logs that have
been evaluated for application
in the fireplace and refer to all
fire log warnings and cautions
marked on the packaging.
Never burn treated construction lumber or
scraps. These woods burn excessively 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.
3. Keep the chimney damper open while any
fire 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. Use care when selecting window treatments
for windows located near the fireplace. Avoid
using combustible flowing window treatments
such as curtains on nearby windows that are of
sufficient length to be blown in front of an open
flame when the window is opened.
6. With the re burning, close the protective
mesh screens to keep sparks and embers
INSIDE the firebox.
7. Keep any combustible furniture or decorative pillows at least 60" (1524 mm) from the
fireplace opening.
8. Never leave your fireplace unattended while
it is burning.
9. Be careful adding wood fuel to the re or
handling fireplace tools such as shovels, tongs
or pokers.
10. Never modify or alter your fireplace system
in any way. To do so may create a potential fire
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 fireplace tools. Exercise
caution when adding wood to your fireplace.
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 fireplace as a “decorative
appliance,” such as with a permanently installed gas
log set, the fireplace damper must be permanently
fixed in the open position. Listed “vent-free” gas
log sets may be used with the 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 optional combustion air kit may not provide all the
air required to support combustion.
Neither the 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/
contractor to ensure that adequate combustion
air has been provided for the fireplace.
15. 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.
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 refractory for the look of authenticity and to provide
safety. Do not light a fire in this fireplace without
the refractory panels in place.
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. The flue damper is a two position (fully open
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
oor, back and sides of the replace. 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 fireplace is not intended to
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 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.
CAUTION
When using a decorative gas appliance, the fireplace damper must
be set to the fully open position.
These fireplaces have been tested and approved
to ANSI/IAS/AGA Z21.11.2 for use with an unvented gas appliance having a maximum rating
of 40,000 BTU and complies with the Standard
for Factory-Built Fireplaces, U.L. 127, when
installed with unvented gas log sets.
Prior to installing any gas log set, (Vented or
Unvented) refer to the fireplace installation
instructions for verification of mantle heights
and placement of combustible materials around
the firebox opening. NEVER INSTALL AN UN-
VENTED GAS LOG SET WITH A BTU RATING
GREATER THAN 40,000 BTU. 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. 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 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 ue. 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:
1. Softwoods produce fast warming and shorter
fires. Hardwoods burn less vigorously, have
shorter flames 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.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
3. Different woods vary widely in flame heights,
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.
6. Most wood needs to be seasoned 9 to 12
months to reduce the moisture content and
produce good steady 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 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.
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
8'
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 find most woods
have approximately the same heating potential
per pound.

LENNOX HEARTH PRODUCTS • ESTATE™ SERIES WOOD-BURNING FIREPLACES • MODELS EST-36/42/50 • CARE AND OPERATION INSTRUCTIONS
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
1. To start a fire in a the fireplace properly, 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 controlled
chimney damper. The chimney damper 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 opening
at the top center just behind the firebox lintel
(Figure 2 ).
EST-36 and 42 models - To lock the damper
blade in the OPEN position, push the damper
handle back and up (away from the front of
the fireplace). To lock the damper blade in
the CLOSED position, pull the damper handle
FORWARD and DOWN (toward the front of
the fireplace).

Always keep the appliance flue damper OPEN
when operating the fireplace.
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.
4. Build a pyramid of three split logs (split will
start much 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
completely out and ashes are cold. Keep closed
when fireplace is not in use to prevent unnecessary 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.
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. Refer to Figure 3
for proper operating conditions.
Figure 2

LENNOX HEARTH PRODUCTS • ESTATE™ SERIES WOOD-BURNING FIREPLACES • MODELS EST-36/42/50 • CARE AND OPERATION INSTRUCTIONS
Smoke spillage often occurs when a fire is first
started, until the fireplace 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
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.
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 installed. See
Figure 4 and refer to Figure 2.
The control lever is located on the lower side
of the fireplace opening behind the screen
panel. To the left for 36" and 42" models and
on the right with 50" models. If your fireplace
is equipped with the optional combustion air
kit, the control lover will move freely. If not, the
retention plate will not have been removed. To
open the air damper, turn upwards. To close,
turn down.

WARNING
Do not operate the combustion
air actuator unless a complete

system has been installed with
your fireplace.
REFRACTORIES
All fireboxes are shipped with a set of refractory brick panels (one floor, two sides, and one
back). The 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.
Refractory panels may easily be repaired or
replaced at costs far below repair and maintenance for masonry fireplaces.
Fully Open or
Fully Closed
(Bi-Fold Doors)
Figure 3
CAUTION
If a smoking condition exists, glass
doors should be closed during
fireplace operation.
Care and Cleaning of Optional 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 re must always be conned within the
boundaries of the fuel grate.
• The replace screens must always be closed
whenever the fireplace is being used.
• Never slam the glass door since it could cause
the glass to break.
• Do not build excessively large or hot res, as
scorching or discoloring of the trim may occur.
• Extreme temperature changes can cause glass
breakage. If the glass doors are cold, do not
build a hot fire and then close the doors.
• 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.
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.
COMBUSTION AIR
A proper amount of combustion air is important
for your replace. 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,
the fire may draw from an outside air source
and pull air in through the chimney. This may
cause smoke spillage into the room.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

LENNOX HEARTH PRODUCTS • ESTATE™ SERIES WOOD-BURNING FIREPLACES • MODELS EST-36/42/50 • CARE AND OPERATION INSTRUCTIONS
Proper care and “burn-in” of the firebox will prolong the period of enjoyment without extensive
maintenance. For the rst 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.
MAINTENANCE GUIDELINES
Your fireplace is designed to operate trouble-free
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 rst
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.
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.
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 contain any
soot that might fall.
If your do 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 exible 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 nailhead
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 over
firing are:
• Burning quantities of scrap
lumber, pine branches, paper or
cardboard boxes which exceed
the volume of the normal log
fire.
• Burning trash, chemicals or
chemically treated combustibles.
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
ue 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.
TROUBLESHOOTING
No Smoking Allowed
Your new fireplace is designed not to smoke if
properly installed and operated per our instructions. 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 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 firebox near the open flue damper.
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.
3. Is your re 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.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Page 7
LENNOX HEARTH PRODUCTS • ESTATE™ SERIES WOOD-BURNING FIREPLACES • MODELS EST-36/42/50 • CARE AND OPERATION INSTRUCTIONS
5. If smoking occurs an hour or two after lighting the fire, perhaps your well-insulated house
is too airtight and there is scarcely any way
for replacement air to enter and feed the fire.
Check to see if your outside combustion air kit
(if installed) is open. 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 heating/cooling system stealing combustion air
from your 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. Figure 5 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.
9. Remember, your fireplace has been designed
as a supplemental heating device only, it is not
intended to heat your entire home.
