PLANNING YOUR INSTALLATION
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL
A correct installation is c ritical and im perative f or reducing fire hazards and perilous conditions that can arise
when wood burning appliances are improperly installed.
The installer must follow all of the manufacturers’ instructions.
The installation of a wood burning appliance m ust conform to local codes and applicable state and federal requirements. Familiarity with these requirements before
installation is essential. Impor tant considerations to discuss with local building officials include:
1. Applicable codes (i.e. Uniform Mechanical Code,
State or Regional Codes)
Electrical codes: Optional Blower Assem blies have
a flexible electrical cord that must be electrically
grounded per local codes or per electrical codes:
In USA, NEC, ANSI/NFPA 70-1987
In Canada, CSA C22.1
WARNING: ELECTRICAL GROUNDING INSTRUCTIONS: THIS APPLIANCE IS EQUIPPED
WITH A THREE-PRONG (GROUNDING) PLUG
FOR YOUR PROTECTION AGAINST SHOCK
HAZARD AND SHOULD BE PLUGGED DIRECTLY
INTO A PROPERLY GROUNDED THREE-PRONG
RECEPTACLE. DO NOT CUT OR REMOVE THE
GROUNDING PRONG FROM THIS PLUG.
2. Local amendments?
3. Is a permit required – cost? (You m ay wish to contact your insurance company to ask if they require
this).
4. Rooms where the installation is not allowed?
SMOKE DETECTORS
Since there are always several potential sources of fire
in any home, we recommend installing smoke detectors.
If possible, install the sm oke detector in a hallway adjacent to the room (to reduce the pos sibility of occasional
false activation from the heat produced by the stove). If
your local code requires a smok e detector be installed
within the same room, you must f ollow the requirem ents
of your local code. Check with your local building department for requirements in your area.
NOTE – This appliance is NOT approved for installation into a Manufactured (Mobile) Home in Canada
or the US.

FLOOR PROTECTION
This appliance requires a non-combustible floor protection for
ember protection. If the f loor protection is to be stone, tile,
brick, etc., it must be mor tared or grouted to f orm a continuous non-combustible surface. If a chimney connector extends
horizontally over the floor, protection must cover the floor under
the connector and at least 2" (51 mm) to either side.
The floor protection must extend completely beneath the
stove and to the front, sides, and rear as indicated:

SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A
wood stove depends primarily on air circulation (convection) to disperse its heat, and therefore, a central
location is often best. There ar e other practical considerations, which must be considered before a f inal selection of locations is made.
♦ Existing Chimneys
♦ Wood Storage
♦ Aesthetic Considerations
♦ Roof Design (Rafter Locations & Roof Pitch)
♦ Room Traffic
♦ Proximity to Combustibles
♦ Electrical Wiring
The installation of this stove will requir e some r esearch.
Once your options are determined, consult with your
local building department who will be able to give you
the necessary installation requirements for your area (Is
a building permit required, room s where installation m ay
not be allowed, etc.).
WARNING: CHECK ALL LOCAL BUILDING AND
SAFETY CODES BEFORE INSTALLATION. THE INSTALLATION INSTRUCTIONS AND APPROPRIATE
CODE REQUIREMENTS MUST BE FOLLOWED EXACTLY AND WITHOUT COMPROMISE. ALTERATIONS TO THE STOVE ARE NOT ALLOWED. DO
NOT CONNECT THE STOVE TO A CHIMNEY SYSTEM SERVING ANOTHER STOVE, APPLIANCE, OR
ANY AIR DISTRIBUTION DUCT. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL VOID THE
MANUFACTURERS WARRANTY.
If you plan to vent your stove into an existing masonry
chimney, have it inspected by a local fire marshal or
qualified installer. Remember that a stove's performance is heavily influenced by the chimney and its location on the roof. An oversized flue m ay not provide ef fective draw, and a flue liner may be required (see Draft
Requirements on page 8). Consult your dealer or quali-
fied installer before final selection is made.
This stove requires pre-installation work to be completed before installation can take place. This may include modification for flue and chimney.

PLANNING YOUR INSTALLATION
COMBUSTIBLE WALL CLEARANCE
WARNING: IT IS VERY IMPORTANT THAT YOU
OBSERVE THE MINIMUM CLEARANCES.
There are listed clearances for your stove which were
determined in a Laboratory test using various "classes"
of stove pipe or chimney. Minimums are first established
for the stove itself and increased based on how much
heat is transferred by each class of pipe.
Do not install the T300HT in an alcove or a conf ined
space, which would be a room or space with under
a 7' (foot) ceiling, and less than 77" (inches) wide.

PROTECTED WALL CLEA RA NCE
Some local codes will allow reduced clearances when the
stove is installed adjacent to a protected wall system. The
variance must be approved by your local building official.
Normally, the protected wall system is defined as a noncombustible m aterial with a m inimum of 1" air s pace behind.
Check your local building codes or with a qualified installer
(Ref. NFPA 211).
VENTILATION REQUIREMENTS
THE FRESH AIR REQUIREMENTS OF THIS APPLI-
ANCE MUST BE MET WITHIN THE SPACE WHERE
IT WILL BE INSTALLED.
Ventilation is essential when using a solid fuel burning
heater. The combustion process of this heater uses
oxygen from inside the dwelling and it may be necessary to open a window or install a vent to provide mak eup air into a dwelling that is well insulated (modern construction standards have resulted in homes that are
highly energy-efficient and that allow little heat loss and
air transfer). Other appliances in the dwelling also contribute to removing air from the dwelling (i.e. clothes
dryers, exhaust fans, fireplaces, and other f uel burning
appliances). If the available fresh air delivery in the
dwelling is insufficient to support the dem ands of these
appliances, problems can r esult (i.e. exces sive negative
pressure can develop in the dwelling which will affect
the rate at which this appliance can draft [See Draft Re-
quirements, page 8], and icing can develop in some environments).
Parallel Installation
* Note: E and F dimensions are measured to side of
stove below the projection of outer top.
PAGE 6
INSTALLATION
BAFFLE PLATES
This appliance has two heavy steel baffle plates that ar e
installed in the upper firebox (over the steel secondary
air supply tubes). During shipment and installation, the
baffle plates might slide around, and may need to be
repositioned (lined up to each other) and pus hed to the
back wall in order for the stove to operate properly.
When in the proper pos ition, the rear edges of the baff le
plates should be flush to the back wall of the firebox.
See Removing Baffle Plates for Cleaning on page 17 for
additional information on installing baffle plates.
INSTALLING LEG LEVELERS
The four leg levelers (included in accessory package),
screw into the tapped (threaded) holes on the bottom of
the four legs. Level the stove by adjusting the screws in
or out.
TYPES OF CHIMNEYS
The chimney is a vital part of your stove installation. A
properly built masonry chimney or a properly installed
factory built chimney will assure a consistent draf t under
a variety of weather conditions (a smoking stove is usually caused by a chimney problem). The stove flue size
is 6 inches diameter, which is approxim ately 28 square
inches minimum . The maxim um flue size should be no
more than (3)-three times the cross sectional area of
the size of the stove flue collar. In this case, that would
be no larger than a 10-inch diameter stack , or approximately 85 square inches maximum.
All chimneys must be installed as specified by local
building codes and according to the chim ney manufacturer instructions (in the case of a fac tory built chimney).
See the chimney manufacturer instructions for exact
specifications. Fact ory built chimneys must com ply with
UL 103HT or ULC S629.
ACCEPTABLE CONNECTOR PIPE FOR INSTALLATIONS
For Standard Residential Clearances: Six (6) inch
minimum, single wall, 25 gage minimum thickness,
stove pipe is acceptable. Three ( 3) pre- drilled holes are
provided in the flue collar for fas tening the pipe s ecurely
to the stove. Use sheet metal screws to do this. Additional sections of single wall pipe should be fastened
together with at least three (3) sheet metal screws each
section. When connecting to the factory built ceiling
support package, use the manufacturer's transition
piece, usually called a dripless connector, to join single
wall pipe to their factory built chimney section.
Minimum Flue Size: The required minimu m diameter
and area required for the flue size is (respectively) 6
inches / 152 mm diameter, which is approximately 28
square inches / 711 square mm. The maximum flue size
should be no more than (3) three times the cross sectional area of the size of the 6 inches / 152 mm diameter
flue collar. In this case, that would be no larger than a
10 inch (254 mm) diameter (area = approx. 85 sq.
inches [216 sq. cm]).
Connection To A Factory Built Chimney: This spac e
heater is to be connected to a factory-built chimney
conforming to CAN / ULC – S629, Standard for 650°C
Factory-Built Chimneys.
For Reduced Residential Clearances: Type L and
listed double wall connector pipe is acceptable. Install
any factory built brand of pipe according to the manufacturer's instructions.
Vapor Barrier At Chimney Penetration
Install all venting components per the Vent Manuf acturers installation instructions. Ensure that there is an effective vapor barrier at the location where the chimney
penetrates to the exterior of the str ucture. This can be
accomplished by applying a non-hardening waterproof
sealant to the following components:
• Around the chimney at the point where the storm
collar will meet the chimney just above the Flashing.
• Along the vertical seam of the c himney pipe, where
it is exposed to the weather.
• On each nail head on the flashing.
• Around the chimney at the point where the storm
collar will meet the chimney just above the flashing.
PAGE 7
Notes:
• On a flat or tarred and gr aveled roofs, nail and seal
the flat roof flashing to the roof on all sides with
roofing compound.
• Do not put screws through the flashing into the
chimney pipe.
INSTALLATION
CHIMNEY INSPECTION
Existing chimneys must be inspected before installing
your stove. Consult your local building department for
chimney code requirements. A m asonry chimney must
have a code approved liner. This liner must not have
broken or missing pieces. Some non-code masonry
chimneys may be brought up to code by being relined.
(Consult your dealer or qualified chimney sweep). Factory built chimneys should also be inspected, first for
creosote deposits (which should be removed), and then
for integrity of the stainless steel liner. Look f or obvious
bulges in the lining, which may indicate the need to replace that section (use a bright flashlight). Also, inspec t
the attic to see that the chimney has proper clearance to
combustible framing members. For interior masonry
chimneys and most f actory built chimneys, this must be
a (2) two-inch air space clearance, which m ust not be
filled with insulation or any other material. An exterior
masonry chimney must have a (1) one-inch air space
clearance.
CHIMNEY HEIGHT REQUIREMENTS
The chimney must extend 3 f eet above the level of roof
penetration and a minimum of 2 feet higher than any
roof surface within 10 feet (see below). Check with your
local building officials for any additional requirements f or
your area.
Due to prevailing winds, local terrain, adjacent tall trees,
a hill, or ravine near the home, or adjacent structures,
additional chimney height or a special chim ney cap may
be required to ensure optimum performance.
DRAFT REQUIREMENTS
The appliance is merely one component of a larger
system. The other equally important component is the
venting system. This is neces sary for achieving the required flow of combustion air to the f ire c hamber and for
safely removing unwanted combustion byproducts from
the appliance. If the venting system's design does not
promote these ends, the system m ay not function properly. Poorly functioning venting systems may create
performance problems as well as be a safety hazard
(i.e. an oversized chimney may result in less than optimum performance. Installations into a large, masonry
chimney may require a liner to improve perform ance) . A
draft test should read greater than .04' W.C. (inches
water column) and less than .08" W.C.
American National Standards Institute ANSI/NFPA 21192, draft 1-7: A chimney or vent shall be so designed
and constructed to develop a flow sufficient to completely remove all flue and vent gases to the outside
atmosphere. The venting system shall satisfy the draft
requirements of the connected appliance in accordance
with the manufacturer instructions.
Top of the flue must be 3’ (915
Requires a
listed termination cap
Top of the flue must be
2’ (610 mm) higher than
any part of roof within
10’ (305 cm) horizontal
mm) higher than highest point
of roof penetration
These rules are minimums. In some
instances, chimney height may need to
be increased to achieve sufficient draft.
To achieve a stable draft, the total flue height requir ed
(from the appliance to termination) is 12 to 15 feet
minimum.

PRODUCT FEATURES AND CONTROLS CARE AND OPERATION
PRIMARY AIR CONTROL
The primary combustion air delivery is controlled by the
Primary Air Control Assembly (The control handle is located below the fuel door). The heat output can be c ontrolled by pushing the control handle in, then incrementally pulling out to the desired heat output setting (See
Care and Operation Section – Primary Air Control, page
12). The fuel, the amount of heat and burn tim es desir ed,
the type of installation are all variables that will af fect the
control setting. The sam e control settings in a variety of
installations will produce different r es ults . You will need to
try different settings so you can learn how much heat to
expect and how long the fire will burn.
Primary Air Control Handle
FUEL DOOR
CAUTION: WHEN OPENING THE DOOR, DO NOT EX-
TEND IT BEYOND ITS NORMAL TRAVEL. OVEREXTENDING THE DOOR TO A FURTHER OPEN POSITION
CAN PUT EXCESSIVE STRESS ON HINGE AREA OF
DOOR AND HINGE PINS AND MAY RESULT IN BREAKAGE.
DOOR OPERATION
The door handle assembly opens and securely latches the
fuel door closed. To open the door, rotate the coil handle to
the 9:00 position until door releases. To close and latch, hold
the coil handle in the 9:00 position, close the door, and then
rotate the handle to the 6:00 position. See illustration above.
GLASS
The Glass is a super heat resistant cer amic that withstands
continuous temperatures up to 1390° F. T his tem perature is
well beyond the temperatures in which you operate your
stove.
This unit is designed to provide a flow of air over the inside of
the glass, where along with high heat helps keep it clean.
When operating the stove on low for extended periods of
time, the glass may get dirty. A short, hot fire (15 - 20 m inutes) will help clean off much of the normal buildup (see
Troubleshooting, page 18). A commercial glass cleaner
designed for stoves is recommended for cleaning.
The glass should be cleaned thoroughly with glass
cleaner and a soft cloth BEFORE the stove is burned.

ability to supplement its primary air with extra "Start-Up"
air. This is achieved by pulling the air control rod all the
way out, and should only be adjusted to this setting when
starting a fire, when refueling or otherwise for short duration’s only.
CAUTION: OPERATION WITH PRIMARY AIR CONTROL IN "START-UP" POSITION (PULLED ALL THE
WAY OUT) FOR EXTENDED PERIODS, WASTES
FUEL AND CAN CAUSE DANGEROUS OVERFIRING
CONDITIONS. NEVER LEAVE STOVE UNATTENDED
ON HIGH SETTINGS.

Adjusting Burn Rate: The primary air control handle can
be pulled out to the open position for higher temperatures
and moved in to a more closed position for lower temperatures.
IMPORTANT: Push air control all the way in (closed)
before pulling rod out to set desired burn rate. This
clears the high burn control plate so it is not left open.
Generally, you will want to set the air control som ewhere
in the low or medium range.
WARNING: OPERATING STOVE ON HIGH FOR EXTENDED PERIODS WASTES FUEL, AND WILL CAUSE
A WHITE BUILD-UP (HAZE) ON GLASS AND CAN
CAUSE DANGEROUS OVERFIRING CONDITIONS.
NEVER LEAVE STOVE UNATTENDED ON HIGH.

PROVIDE ADEQUATE AIR FOR COMBUSTION
In well insulated and weather tight homes, it may be difficult to establish a good draft up your chim ney. The poor
draft is caused by a shortage of air in the house. To provide the needed air, crack a window on the windward side
of the house.
USE CONTROL SETTINGS THAT WORK FOR YOU
The fuel, the amount of heat you want, the type of installation you have and how long you wish the fire to burn are
all variables that will affect the control setting. T he same
control settings in a variety of installations will produce
different results.
Familiarize yourself with your stove by trying different settings so you can learn how much heat to expect and how
long the fire will burn. It may take a week or two to learn
but your patience will be rewarded by the warmth and
pleasant satisfaction that only a wood fire can provide.
PAGE 12
CARE AND OPERATION
BREAK-IN PERIOD
Your stove finish is a high temperature paint that requir es
time and temperature to completely cure. We recommend that you ventilate the house during the initial burns .
The paint emits non-toxic odors during this process.
KEEP YOUR HOUSE WELL VENTILATED DURING
THE CURING PROCESS TO PREVENT ACTIVATION
OF YOUR HOME SMOKE DETECTOR.
The paint manufacturer recommends three burn c ycles to
cure the paint. The first two burns should be low heat,
approximately 250°F., for 20 minutes eac h, using paper
and light kindling.
After each 20-minute burn, allow the appliance to cool
completely. The third burn should be at least medium
high or about 450°F. for 45 - 60 minutes . The paint will
become soft and em it non-toxic haze during these bur ns.
Keep the area well ventilated.
As the paint cures it will become s lightly lighter in color.
Eventually the entire surface will become an even color.
Once the paint has been softened and cooled two or
three times, it will harden. Do not turn on a blower during
the curing process. Do not place anything on the stove
surface until the paint is completely cured. Do not attem pt
to repaint the stove until the paint is c ompletely cured. If
the surface later becomes stained or marred, it may be
lightly sanded and touched up with spray paint from the
same paint (See Small Area Paint Touch-up, page 16).
Paint is available at your local authorized Lennox Hearth
Products dealer. Never attempt to paint a hot stove.
FIRST FIRE
When your installation has been completed and inspected you are ready to build your first fire.
1. Pull the primary air-control to the full open position
(located below the ash lip).
2. Open door and build a small fire in the stove using
paper and dry kindling. Wait a f ew minutes f or a good
updraft to establish the fire.
3. Now place two or three thoroughly dried logs on the
burning kindling and secure door.
4. After about 25-30 minutes of bur ning (when fire is well
established), push in the primar y air draft control (this
will reset control plates), then pull out to a medium
setting. This will keep the fire burning at a moderate
level so heat is transferred through the stove rather
than up the chimney.
5. Once a bed of coals has been established, adjust the
air-intake draft control to a low by pushing the air control rod all the way in (closed) and then pulling the rod
out incrementally to a low or medium- low setting. This
action clears the high burn control plate so it is not left
open.
6. During the first few fires, k eep the combustion rate at
a low to moderate level. Avoid burning fires with the
draft control wide open for long periods of time. This
results in an updraft fire with m ost of the heat escaping up the chimney.
WARNING! READ AND USE THE INFORMATION
PROVIDED IN THIS SECTION. TO DISREGARD THIS
MAY CAUSE SERIOUS PERMANENT DAMAGE TO
THE STOVE AND VOID YOUR WARRANTY. IT IS
BEST TO WARM YOUR STOVE UP SLOWLY AND
KEEP IT AT A MODERATE LEVEL.
HOW TO START AND MAINTAIN A FIRE
1. Open the primary air control by pulling the handle out
ward to the full open position. This allows the firebox
and fresh fuel to quickly come up to ideal operating
temperature.
2. Build your fire directly on the firebrick covering the
bottom of the stove.
a. Plac e five or six loos ely crumpled sheets of news-
paper in the stove.
b. Add a small amount of dry kindling randomly on
the top of the newspaper.
c. Place a few more loosely crumpled newspapers
on top of the kindling and light the bottom paper
first, then light the top paper. Once the fire is well
underway, close the fuel door. The upper fire
should preheat the chimney and create an effective draft while the lower fire ignites the kindling.
3. After the kindling is burning well, add increasingly
larger pieces of wood until the fire is actively burning.
4. Once a bed of coals has been established, adj ust the
primary air control to a lower setting by pushing the
air control rod all the way in (closed) and then pulling
the rod out incrementally to the desired setting. Tips Adjust the primary air control to a m edium to low setting for a slow and more efficient burn. On higher
settings, it is more ef ficient to burn with a bright but
not roaring fire.

CARE AND OPERATION
REFUELING
To refuel the stove, first move the prim ary air control to
high (pulled out). Let the fire "liven up" for about one m inute. Open the fuel door about 1/2" and hold in this position about 30 seconds or until stove is drafting well.
Open the door and add wood. If the fire or coal bed is
almost depleted and a full load of cord wood is added, it
may be necessary to adjust the primar y air control wide
open to re-establish a lively fire. The use of start-up air
should only be used for a short period of time.
NOTE: After refueling and the wood is burning at a bris k
rate, reset the primary air control to the desired position
by pushing the primary air control rod all the way in and
then pull it back out to the desired setting.
BURN RECOMMENDED FUEL
This appliance is approved for use with untreated natural
dry wood only (see Important Warnings, page 2, #8). Do
not burn particleboard scraps or pressed logs using
bonding agents because they can produce conditions that
will deteriorate metal. Green or uncured wood does not
work well as fuel, and can cause increased creosote
buildups. The value of green wood as a source of heat is
limited. Do not overload or use k indling wood or m ill ends
as primary fuel as this may cause overfir ing. Overfiring is
a condition where excessive temperatures are reached,
beyond the design capabilities of the stove. The damage
that occurs from overfiring is not covered under the stove
warranty.
WARNING: BURNING IMPROPER FUEL (I.E. CHARCOAL) CAN RESULT IN CARBON MONOXIDE POISONING WHICH MAY LEAD TO DEATH!
CARBON MONOXIDE POISONING – EARLY SIGNS
OF CARBON MONOXIDE POISONING RESEMBLE
THE FLU WITH HEADACHES, DIZZINESS, OR NAUSEA. IF YOU HAVE THESE SIGNS, GET FRESH AIR
AT ONCE! HAVE THE HEATER INSPECTED BY A
QUALIFIED SERVICE TECHNICIAN. SOME PEOPLE
ARE MORE AFFECTED BY CARBON MONOXIDE
THAN OTHERS. THESE INCLUDE PREGNANT
WOMEN, PEOPLE WITH HEART OR LUNG DISEASE
OR ANEMIA, THOSE UNDER THE INFLUENCE OF
ALCOHOL, A ND THOSE AT HIGH ALTITUDES.

CARE AND OPERATION
WHY SEASONED WOOD?
The key to the success of a good fire that produces heat
from a woodstove is the wood. It needs to be well-seasoned
natural wood.
What does “Well-Seasoned” mean?
When a tree is cut down, the wood is green, full of sap and
moisture. This moisture content can exceed 80%, which
must be reduced to less than 20%. Wood properly seasoned
is then capable of generating the heat the stove was designed to provide.
Green wood does not burn easily. Attempting to burn green
wood often results in a lot of sm oke and very little fir e. Tim e
is the most im portant factor in seasoning wood. Ideally the
moisture content should be reduced to 11-20%, although
very few of us will be able to check that figure. There ar e
several steps that should be taken to ens ure that that you
come close to these figures.
SEASONING GUIDE
Softwoods – 6 months to 18 months
Hardwoods – 12 months to 24 months
Logs that are 5” diameter across or larger should be split in
half, three pieces if over 8 inches, and four pieces when over
a foot across. If the tree was fell 2 to 4 years ago, it still
needs to be cut, split, and seasoned for 6 to 24 m onths depending on the wood.
WOOD STORAGE
Wood to be seas oned should be stacked in an area open
enough to ensure good air circulation on both sides – leaving
adequate space between woodpiles to walk comfortable. Do
not stack wood against a wall or building. It helps to elevate
the woodpiles off the ground (two 2 x 4’s running lengthwise
beneath the woodpile works well). This allows air to flow under the bottom logs.
Wood that is k ept outdoors, either covered with a tarp, or
not covered at all, will not burn well until it has been in an
enclose space for one to two months.
PAGE 15
MAINTENA NCE
SMALL AREA PAINT TOUCH-UP
The stove body is painted with a quality high-temperature
stove paint. Use only model TSPK-B Stove Paint, Catalog
# 70K99. Do not touch-up your stove with any other paint.
Using one small piece of 320 gr it sand paper and lightly
sand the blemish so that the edges are “feathered” or
smooth to the touch between the painted and bare surfaces. Do not let the sand paper gum up with paint, as
this will cause scratches on the metal surface. If there are
any scratches, use 600 grit sandpaper ins tead. Mask off
surfaces you do not want painted. Paint lightly over the
bare surface firs t as this will act as an undercoat. Then
paint over a larger area in smooth even strokes to blend.
See Break-In Period on page 13 for information on
curing the paint.
ASH REMOVAL AND DISPOSAL
CAUTION: MAKE SURE THAT THE FIRE IS OUT AND
THE STOVE IS COLD BEFORE REMOVING ASHES!
Ashes can hold live embers for several days, and must
be disposed of with care.
NEVER place ashes in a cardboard box or any other
combustible receptacle.
Proper Disposal of Ashes:
Ashes should be placed in a metal container with a tight
fitting lid. The closed container of ashes s hould be plac ed
on a noncombustible floor or on the ground, well away
from all combustible materials, pending final disposal.
If the ashes are disposed of by burial in soil or other wise
locally dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled.
DOOR, AND GLASS GASKETS
A 3/4" spun fiberglass rope gasket provides the seal
around the fuel door and a 1/8” x 1” flat woven gasket
glass provides the seal around the glass. Should these
gaskets become frayed or damaged they should be replaced with the same size and type as the original gasket.
Contact your dealer for ordering. Use high temperature
silicone sealer as an adhesive for the door gask et. The
glass gasket has a s elf-adhesive backing (see Replace-
ment Parts, pages 20-21).
WARNING: THE GASKETS MUST BE KEPT IN GOOD
CONDITION. DO NOT LEAVE THE STOVE BURNING
WITH THE FUEL DOOR OPEN OR AJAR. THIS WILL
CAUSE EXCESSIVE HEAT BUILD UP IN THE UNIT
AND COULD IGNITE SURROUNDING COMBUSTIBLES AS WELL AS DAMAGE THE ST OVE BY OVERFIRING IT. OVERFIRING IS A CONDITION WHERE
EXCESSIVE TEMPERATURES ARE REACHED, BEYOND THE DESIGN CAPABILITIES OF THE STOVE
(SUCH DAMAGE IS NOT COVERED BY THE MANUFACTURERS WARRANTY).
FIREBRICK
The firebrick should be inspected periodically and replaced if damaged (crumbling or excessively cracked).
SERVICING GLASS
CAUTION: BE CAREFUL NOT TO ABUSE DOOR AS-
SEMBLY BY STRIKING OR SLAMMING IT. IF THE DOOR
ASSEMBLY OR GLASS IS BROKEN OR DAMAGED,
THEY MUST BE REPLACED BEFORE HEATER CAN BE
SAFELY OPERATED. USE ONLY COMPONENTS PROVIDED BY THE MANUFACTURER AS REPLACEMENT
PARTS.
Cleaning Glass: Ensure stove is cold prior to cleaning glass .
A commercial glass cleaner designed for stoves is recommended. Do not use abrasive cleaners.
Replacing Glass:
1. Remove door from s tove by lifting door up and off hinge
pins: Place the door on a flat protected (towel) clean flat
surface with the inside of the door fac ing up. Remove
the glass clips (by removing screws holding c lips), then
carefully remove broken glass one piece at a tim e (protective gloves are recommended).
2. Clean the area where the glass with gasket will be in-
stalled.
3. Install new glass with gask et (use only factory 5-mm
glass with glass channel gasket. Do not substitute).
Carefully reinstall glass clips. Be very careful not to
overtighten screws.
4. Reinstall door.

CLEANING BLOWER INTAKE
If an optional blower kit (catalog #14M41) is installed, the
blower air intake requires cleaning at leas t onc e a year to
remove lint, dust, etc. If there are pets in the dwelling, the
intake should be cleaned at least twice a year.
CREOSOTE FORMATION AND NEED FOR REMOVAL
What is Creosote - W hen wood is burned slowly, it pro-
duces tar and other organic vapors, which c ombine with
expelled moisture to for m creosote. T he creosote vapor s
condense in the relatively cool chimney flue of a slowburning fire. As a result, creosote residue accumulates
on the flue lining. W hen ignited this creosote makes an
extremely hot fire. Also, creosote deposits tend to form in
long runs of venting where gases become too c ool prior
to exhausting. Note: Single wall pipe cools rapidly, therefore installations using this type of flue are more sus ceptible to creosote deposits.
To inhibit the build up of creosote, adjust the prim ary air
control to a medium-high or high setting for a 10-m inute
period each day. Do not attempt to burn out heavy creosote accumulations in this manner. This must be removed from the chim ney by scraping or brushing to reduce the risk of a chimney fire.
Burn Approved Fuel Only - This stove is approved for
burning dry seasoned natural wood only. Using green or
inadequately seasoned wood may increase creosote
buildup.
Inspection Frequency - The chimney connector and
chimney should be inspected at least twice m onthly during the heating season to determine if a creos ote buildup
has occurred. If creosote has accumulated it should be
removed to reduce the risk of a chimney fire.
Cleaning - Remove the baffle plates in the fir ebox prior
to having your chimney cleaned (should be done by a
qualified chimney sweep). See following – Removing
Baffle Plates for Cleaning).
Removing Baffle Plates for Cleaning
Note: The smok e baf f le in the upper firebox area consists
of two heavy gage steel plates. One of these plates has a
welded strap to overlap the seam, which runs front to
back between the two. Before rem oving the baffle plates
from the firebox, wearing a pair of leather or work gloves
is recommended.
1. To remove the baffle, reach inside the firebox and
slide one plate over the other.
2. Next move the metal plates, stacked one on top of
the other, sideways toward the center of the stove.
3. Then move the two baffle plate toward the front of the
stove to clear the ledge they rest on at the rear. Be
mindful these metal plates are quite heavy, so use
care in lowering them out of the way.
4. Once the baffle plates are out of the firebox, the flue
can be cleaned. The accumulated soot that is removed by brushing will fall to the firebox floor where it
can be removed and disposed of.
WARNING! DO NOT OPERATE THE STOVE WITHOUT THESE BAFFLE PLATES PROPERLY INSTALLED. THIS WILL VOID WARRANTY.
In the event of a chimney fire - Mak e sur e the f uel door
is securely closed. Adjust the primary air control to the
lowest (most closed) setting. Call the fire department
immediately. After a chim ney fire, the com plete chimney
system should be checked by a qualif ied technician before further use.
Consult your dealer for suggestions on proper chimney
care. Contact your local municipal or provincial fire
authority for information on how to handle a chimney fire.
Have a clearly understood plan for handling a chimney
fire.
REINSTALL BAFFLE PLATES
After your chimney has been swept, reinstall the baffle
plates. See – Removing Baffle Plates for Cleaning (on
this page) and reverse steps.

TROUBLESHOOTING
SMOKES OUT FUEL DOOR WHEN OPEN (SEE ✸✸✸✸)
1. The primary air control is closed.
2. The chimney is too cool. Set the pr imary air control on
"HIGH" for a few minutes before opening the fuel door.
3. Excess creosote will not only restrict your draft but it will
create a risk of a cr eosote fire. Strictly adhere to m aintenance requirements as outlined in this m anual. If exce ss
creosote has built up on the inside of the firebox sides
and door, burn a small hot fire at intervals that ar e more
frequent with air control on HIGH for a few minutes.
4. Deposits may have built up in the chimney and are restricting the draft, or the spark arrester on top of the
chimney may be plugged.
5. Chimney diameter too large or too small to provide adequate draft.
6. The house is too airtight (usually takes 20 to 30 minutes
for problem to appear as stove lowers air pressure in
house). Crack a window open or provide an outside
source of air near stove.
7. Insufficient vertical height to chimney to achieve adequate
draft.
DOES NOT PRODUCE ENOUGH HEAT (✸✸✸✸)
1. Using green or insufficiently cured wood.
2. Excessive draft.
3. High ceilings (heat rises quick ly, but can be recirculated
by a well-placed ceiling fan with a winter/summer switch).
4. The area to heat is too large (square foot heating estimates are based on "average" climates and home design).
5. There is an obstruction in the chimney.
6. The chimney or chimney cap is restricted by creosote
preventing enough draw to sustain a "high" heat output
rate.
DOES NOT MAINTAIN A FIRE (✸✸✸✸)
1. Soft wood does not burn as long or as well as seas oned
hardwood resulting in a short burn time.
2. Wood size too small. Burns at too rapid a rate.
3. The gasket seal on the fuel door , or glass is leaking air.
Repair or replace it if necessary.
4. Excessive Draft.
5. There may be an obstruction in the chimney.
BACKPUFFING (✸✸✸✸)
1. Downdraft in the chimney (a special wind cap may be
needed).
2. The house is too air tight (ventilation is needed).
1. Insufficient vertical height to chimney to achieve adequate
draft.
ODORS
1. Creosote accumulation in firebox (brush out on next
cleaning).
2. Chimney downdraft when stove is not operating (close
the primary air control).
2. Paint curing on first several burns.
DIRTY GLASS (✸✸✸✸)
1. Poor draft conditions.
2. Long burn periods at low draft settings.
3. Burning wet, pitchy or spongy wood.
4. Poorly arranged logs (too close to glass).
✸✸✸✸ Draft problems; if installing into a larger flue, it may
be necessary to use a full length liner to achieve adequate draft for the appliance. A draft gauge should read
a minimum of .05" w.c. (inches water column) not to
exceed .07" w.c. for optimum performance (See Draft
Requirements, page 8).
OVERFIRING DAMAGE
If the heater or chimney connector glows, you are overf iring.
Other symptoms m ay include: Cracking, warping or burning
out of components, st ove glass may develop a haze, which
will not come off with cleaning.
Overfiring of a stove is a condition where excessive temperatures are reached, beyond the design capabilities of the
appliance. The damage that occurs from overfiring is not
covered under the manufacturers limited warranty.
The following are a few conditions that should be evaluated and (corrected if necess ary) if an overf ir ing condition
is suspected:
Overfiring Caused From Improper Installation - Ensure
that all installation requirements have been met as outlined
in the installation manual. The chim ney should be clean and
in good repair. A draft test should be performed to determine
if the draft requirements of the appliance ar e being met. A
draft gauge should read between .05 and .07 inc hes water
column (" W .C.). Excess ive draft (above .07 " W .C.) will allow too much combus tion air to be pulled in whic h results in
hotter burns. Too little draft (below .05 " W .C.) will not allow
enough combustion air delivery to maintain a fire (this m ay
result in improper operation of appliance, i.e. wont m aintain
fire unless fuel door is left open. See below, Overfiring
Caused From Improper Operation).
Overfiring Caused From Improper Operation - Operate
this appliance only as outlined in this manual. Never burn the
appliance with the fuel door open or ajar. Do not operate this
stove with the Air Control in the "open" position (pulled out)
for extended periods. This wastes fuel and can cause dangerous overfiring conditions. NEVER leave the stove unattended on high settings.
Overfiring Caused From Improper Maintenance - Strictly
adhere to all maintenance requirements at frequent intervals
as prescribed in this m anual including cleaning of flue and
stove. Should the fuel door or glass gaskets become worn or
damaged, they should be replaced.
Overfiring Caused From Improper Fuel - This appliance is
approved for use with natural dry well seasoned wood only
(ask your authorized dealer what are approved fuels for your
area). Do not burn garbage, particleboard scraps, or pressed
logs using bonding agents because they can produce c onditions that will deteriorate metal. Do not overload or us e kindling wood or mill ends as prim ary fuel as this may cause
overfiring.
