PLANNING YOUR INSTALLATION
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL
A correct installation is critical and imperative for 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 must conform to local codes and applicable state and federal requirements. Familiarity with these requirements before
installation is essential. Important considerations to discuss with local building officials include:
1. Applicable codes (i.e. Uniform Mechanical Code,
State or Regional Codes)
Electrical codes: Optional Blower Assemblies 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. DO
NOT ROUTE POWER CORD UNDER OR IN
FRONT OF APPLIANCE.
2. Local amendments?
3. Is a permit required - cost? (You may wish to
contact your insurance company to ask if they re-
quire 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 smoke detector in a hallway adja-
cent to the room (to reduce the possibility of occasional
false activation from the heat produced by the stove). If
your local code requires a smoke detector be installed
within the same room, you must follow the requirements
of your local code. Check with your local building de-
partment for requirements in your area.
NOTE – This appliance is NOT approved for installa-
tion into a Manufactured (Mobile) Home in Canada
or the US.

FLOOR PROTECTION
This appliance requires ½" (13 mm) minimum noncombustible floor protection designed for solid fuel burning appliances having a thermal conductivity of k = .84
BTU in/ft or equivalent. If the floor protection is to be
stone, tile, brick, etc., it must be mortared or grouted to
form a continuous non-combustible surface (See Using
Alternate Material As Floor Protector below). 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:
USA REQUIREMENTS
16” min. to the front of the fuel door glass
8” min. beyond the sides of the fuel door opening
6” min. to the back of the stove body
CANADA REQUIREMENTS

USING ALTERNATE MATERIAL AS FLOOR PROTECTOR
The alternate material used as a floor protector must be
constructed of a durable noncombustible material having an
equal or better insulating value (lower k value) of k = .84
BTU / IN FT
exceeds r = 1.19 HR °F FT
2
HR °F or a thermal resistance that equals or
2
IN/BTU. With these values, determine the minimum thickness/material required using the
formula and the table shown here (see chart - Alternative
Floor Protection Materials).
Note: Any noncombustible material having a thickness of
1/2” (12.7 mm) whose k value is less than .84 or whose r
value is more than 1.19 is acceptable. If the alternate
material used has a higher k value or lower r value will
require a greater thickness of the material used. In some
cases, if the k value is less or the r value higher, a thinner
material may be used.
Methods of determining floor protection equivalents:
To determine the thickness required for any material
when either the k or r values are known:
T
= Thickness of material in inches
M
KM = K value of desired material
= Minimum listed thickness
T
L
rM = r value of desired material
Example: Micore CV230 is to be used for the floor protection. How thick must this material be?
The following formulas give the means of determining
minimum thickness required of alternate materials.
Using the k formula:
Desired Thickness k value of desire Minimum thickness
of the alternate = material (per inch) x of Listed
material k value of listed Material
TM (inches) = KM x T
T
(inches) = 0.43* x 1/2”
M
material (per inch)
.84
.84
L
Answer using k: 0.50 x 0.50” = 0.25 = 1/4”
1/4” thickness Micore will be required.
Using the r formula:
TM (inches) = 1.19 x T
r

L
TM (inches) = 1.19 x .5”
2.33*
Answer using r: 0.50 x 0.50” = .25 = 1/4”
3/8” thickness Micore will be required.
At times it is important to know what combination of materials are acceptable for use as floor protection. The “R
values” are used to determine acceptable combinations
of materials because “R values” are additive where r and
k values are not.
“R value” = 1 = r x thickness of material used

PLANNING YOUR INSTALLATION
SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A
woodstove depends primarily on air circulation (convection) to disperse its heat, and therefore, a central location is often best. There are other practical considerations, which must be considered before a final 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 require some research.
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, rooms where installation may
not be allowed, etc.).
COMBUSTIBLE WALL CLEARANCE
WARNING! IT IS VERY IMPORTANT THAT YOU OBSERVE THE MINIMUM CLEARANCES.
These are the listed clearances for this appliance which
were determined in laboratory tests. Minimums are first
established for the stove itself and increased or decreased based on how much heat is transferred by the
pipe.
USA and CANADA RESIDENTIAL ONLY (not approved
for manufactured (mobile) home) using single wall pipe
connector to the top of the stove.
A 16" / 406 mm D 11" / 279 mm
B 40" / 102 cm E 30" / 762 mm
C 30" / 762 mm F 20" / 508 mm
CORNER INSTALLATION
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 may not provide effective draw, and a flue liner may be required (see Draft
Requirements, page 9). Consult your dealer or qualified
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.
PARALLEL INSTALLATION
PAGE 6
PLANNING YOUR INSTALLATION INSTALLATION
REDUCED MASONRY STRUCTURE CLEARANCE
(ALCOVE)
Your stove can be installed in a masonry structure with
reduced clearances if the structure was built to National
Building Code for fireplaces and chimneys (UBC 37).
The firebox of the masonry structure must be of adequate size to allow a minimum of 6" (152 mm) clearance
to the sides and top of the stove and 2" (51 mm) clearance to the rear. All stove models must be installed on
their original listed legs or base unless otherwise specified by OMNI Testing Laboratory.
The minimum venting requirement is a listed chimney
liner that extends from the flue collar of the stove to the
first tile liner of the chimney where it is sealed. All joints
and connections must be made airtight to prevent leaking
and
downdrafts.
PROTECTED WALL CLEARANCE
Some local codes will allow reduced clearances when the
stove is installed adjacent to a protected wall system.
Your local building official must approve the variance.
Normally, the protected wall system is defined as a noncombustible material with a minimum of 1" (25.4 mm) air
space behind. Check your local building codes or with a
qualified installer (Ref. NFPA 211).
INSTALLING (OPTIONAL) MARBLE ACCENTS
See Optional Accessories, page 25 for ordering information.
Important Note; Optional marble cannot be used if tem-
perature probe is used.
Marble is a natural product and therefore each piece will
have its own unique character. Marble can be scratched
so care should be taken to avoid putting heavy or rough
objects (trivet/steamers) on the surface. If the marble
should become scratched, the scratch may be removed
or diminished by polishing it with jewelers rouge (which
can be purchased at many hardware stores). Do not in-
stall the marble before curing the paint.
The marble set consists of 2 pieces. A large piece that
fits onto the stove top and a smaller piece that fits onto
the ashlip (located below the fuel door).
VENTILATION REQUIREMENTS
THE FRESH AIR REQUIREMENTS OF THIS APPLIANCE 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 make-up air
into a dwelling that is well insulated (modern construction
standards have resulted in homes that are highly energyefficient 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 fuel burning appliances). If the
available fresh air delivery in the dwelling is insufficient to
support the demands of these appliances, problems can
result (i.e. Excessive negative pressure can develop in
the dwelling which will affect the rate at which this appliance can draft [See Draft Requirements, page 9], icing
can develop in some environments).
Installation Steps:
Install the ceramic fiber blanket, gasket strips and marble
set as follows:
Note: The fiber blanket and gasket strips are provided with the
stove: The marble sets are optional accessories.
1. Using scissors cut the ceramic fiber blanket so that it
fits into the recess of the stovetop.
2. Place the top marble piece onto the ceramic fiber
blanket.
3. Place the gasket strips into the recess of the ashlip
so that they are evenly spaced. This will slightly ele-
vate the marble so that it is not making direct surface
contact. Note: Insulation is not required in this area.
4. Place the ashlip marble onto gasket strips in ashlip
recess.

INSTALLATION
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 draft under
a variety of weather conditions (a smoking stove is usually caused by a chimney problem). The stove flue size is
6 inches (I52 mm) diameter, which is approximately 28
square inches (711 square mm) minimum. The maximum 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 (254
mm) diameter stack, or approximately 85 square inches
216 square cm) maximum.
All chimneys must be installed as specified by local
building codes and according to the chimney manufacturer instructions (in the case of a factory built chimney).
See the chimney manufacturer instructions for exact
specifications. Factory built chimneys must comply with
UL 103HT or ULC S629.
Connection To A Factory Built Chimney: This space
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 Manufacturers installation instructions. Ensure that there is an effective vapor
barrier at the location where the chimney penetrates to
the exterior of the structure. 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 chimney 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.
ACCEPTABLE CONNECTOR PIPE FOR INSTALLATIONS
For Standard Residential Clearances: Six 6 inch (152
mm) minimum, single wall, 25 gage minimum thickness,
stove pipe is acceptable. Three (3) pre-drilled holes are
provided in the flue collar for fastening the pipe securely
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 minimum 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]).
Notes:
• On flat or tarred and graveled 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 chim-
ney pipe.
CHIMNEY INSPECTION
Existing chimneys must be inspected before installing
your stove. Consult your local building department for
chimney code requirements. A masonry 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 for obvious
bulges in the lining, which may indicate the need to replace that section (use a bright flashlight). Also, inspect
the attic to see that the chimney has proper clearance to
combustible framing members. For interior masonry
chimneys and most factory-built chimneys, this must be a
(2)-two inch (51 mm) air space clearance, which must not
be filled with insulation or any other material. An exterior
masonry chimney must have a (1) one-inch (25.4 mm) air
space clearance.
PAGE 8
INSTALLATION
CHIMNEY HEIGHT REQUIREMENTS
The chimney must extend 3 feet (914 mm) above the
level of roof penetration and a minimum of 2 feet (610
mm) higher than any roof surface within 10 feet (305 cm)
(see below). Check with your local building officials for
any additional requirements for 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 chimney cap may
be required to ensure optimum performance.
Top of the flue must be 3’ (915
mm) higher than highest point
of roof penetration
Top of the flue must be
2’ (610 mm) higher than
any part of roof within
10’ (305 cm) horizontal
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 required
(from the appliance to termination) is 12 to 15 feet (366 to
457 cm) minimum.
DRAFT REQUIREMENTS
The appliance is merely one component of a larger system. The other equally important component is the venting system. This is necessary for achieving the required
flow of combustion air to the fire chamber and for safely
removing unwanted combustion byproducts from the appliance. If the venting system's design does not promote
these ends, the system may 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 performance). 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: 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.

PRODUCT FEATURES AND CONTROLS
PRIMARY AIR CONTROL
The primary combustion air delivery is controlled by the
Primary Air Control Assembly (The control knob is located above the fuel door). The heat output can be controlled by sliding the handle to a higher or lower heat
output setting (See Care and Operation Section – Pri-
mary Air Control, page 13). The fuel, the amount of heat
and burn times desired, the type of installation are all
variables that will affect the control setting. The same
control settings in a variety of installations will produce
different results. 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 Knob
CATALYTIC COMBUSTOR
How it works: From 5 to 30 percent of the chemical
energy contained in every log escapes up the chimney
when wood is burned in a conventional stove. The
catalytic combustor is designed to make use of this energy, converting it into useful heat as it lessens chimney
creosote build-up and air pollution. The catalytic combustor consists of a durable temperature resistant ceramic composition, which is extruded into a cellular, or
honeycomb, configuration. After extrusion, this ceramic
monolith is fired and then covered with a noble-metal
catalyst. When wood smoke contacts this catalyst,
chemical changes occur that causes the smoke to ignite
at temperatures around 600° F. Normally, smoke will
ignite and burn only at temperatures around 1000° F.
CATALYTIC BYPASS DAMPER CONTROL
The operating handle of your Bypass Damper Control is
located on the front of the Stove Flue Collar. By moving
the Bypass Damper Control the operator can route the
exhaust either through the Catalytic Combustor (pushed
in) or directly up the flue (pulled out). When starting a
fire or refueling, the bypass damper control handle
should be pulled out. Once the fire is established it
should be pushed in.

CAUTION: WHEN OPENING THE DOOR, DO NOT EXTEND 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, then rotate the handle to the 6:00 position. See illustration above.
GLASS
The Glass is a super heat resistant ceramic that withstands
continuous temperatures up to 1390° F. This temperature 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 minutes) will help clean off much of the normal buildup (see
Troubleshooting – Dirty Glass, page 20). 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.
PRIMARY AIR CONTROL
This appliance is equipped with a control for the combustion air located above the fuel door. Slide the control to
the right for a slower burn rate, to the left for a higher
burn rate. It may take a while to get accustomed to the
sensitive draft control. Small movements left or right will
change the heat output of the stove. To lock the air control in the desired position, turn the knob clockwise. In the
open (far-left) position, the fire will kindle more quickly.
This should be closed to the medium/low position once
the fire is burning well.
You will generally want to set the primary air control on
low or medium. The stove is safe burning on any setting
as long as combustibles are kept at the specified safe
distances.
PROVIDE ADEQUATE AIR FOR COMBUSTION
In well insulated and weather tight homes, it may be difficult to establish a good draft up your chimney. 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 settings. The
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 13
CARE AND OPERATION
BREAK-IN PERIOD
Your stove finish is a high temperature paint that requires
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 cycles to
cure the paint. The first two burns should be low heat,
approximately 250°F., for 20 minutes each, 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 emit non-toxic haze during these burns.
Keep the area well ventilated.
As the paint cures it will become slightly 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 attempt
to repaint the stove until the paint is completely cured. If
the surface later becomes stained or marred, it may be
lightly sanded and touched up with spray paint from the
same paint manufacturer (See Small Area Paint Touch-
Up, page 17). Paint is available at your local authorized
Lennox Hearth Products dealer. Never attempt to paint a
hot stove.
HOW TO START AND MAINTAIN A FIRE
1. OPEN the bypass damper control by pulling it toward
you. In the OPEN position the draft air will bypass the
catalytic combustor and make starting the fire easier.
2. Set the primary air control lever on HIGH. The HIGH
setting will maximize your primary combustion air.
3. Build a fire directly on the firebrick covering the bottom
of the stove.
a. Place five or six loosely crumpled sheets of
newspaper 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.
4. Once the kindling is ignited and burning on its own,
close the fuel door. The upper fire should help preheat
the chimney and create an effective draft while the
lower fire ignites the kindling.
5. When the kindling is burning well, add increasingly
larger pieces of wood until the fire is actively burning.
6. When the fire is well established, close the bypass by
pushing the control rod in. The optional catalytic temperature probe should read 500-600°F (It takes approximately 20 - 25 minutes to reach this temperature).
CATALYTIC COMBUSTOR
During the start-up of a cold stove, a medium to high firing rate must be maintained for about 20 – 25 minutes.
The high firing rate will ensure that the stove, the flue, the
catalyst, and the fuel are all stabilized at proper operating
temperatures. If the optional temperature probe is used,
even though it may reach a temperature of 600° F. within
only two or three minutes after the fire is started, do not
set the primary air control to the "LOW" position until approximately 20-25 minutes have passed. Setting the
primary air control on "LOW" too early could result in either the fire or the catalytic combustor going out.
PAGE 14
7. Set the primary air control to the desired setting. Your
stove will now provide efficient and safe heat for your
home.
CARE AND OPERATION
Refueling *
1. Open the damper bypass control by pulling it toward
you.
2. Set the primary air control set to high.
3. Open the door approximately 1/2 inch (13 mm),
then wait for about thirty seconds. Open the door
and add wood, then close the door.
4. If the optional temperature probe is used wait for a
reading of approximately 600 degrees, then close
the damper bypass control (push it in). If the optional temperature probe is not used, wait approximately 10 minutes, and then close the bypass
damper control.
5. Adjust the primary air control to the desired setting.
Notes
h Depending on the type and size of the fuel load as
well as the length of time the stove has been burning, your catalytic combustor should operate between 1000 to 1800 degrees.
h (If the optional blower is installed) Ensure blower is
turned off during start-up and refueling, as it will affect the accuracy of temperature probe reading.
* If the stove has been burning on a medium to high
burn rate for approximately 20 minutes or more, no refiring is necessary when refueling. Just open the bypass, set the primary air control to high, open the door
approximately 1/2 inch (1 cm), and wait for about thirty
seconds. Load the fuel, close the door, close the bypass
and set the primary air control to normal operation.
Temperatures within the firebox should be hot enough
to maintain the catalytic operation.
BYPASS DAMPER CONTROL
The operating handle of your bypass damper control is
located on the front of the stove flue collar. By moving
the bypass damper control, the operator can route the
fire either through the catalytic combustor (pushed in) or
directly up the flue (pulled out). When starting a fire or
refueling, the bypass damper control should be pulled
out. Once the fire is established, it should be pushed in.
PAGE 15
FUEL
BURN RECOMMENDED FUEL
This appliance is approved for use with untreated natural
dry wood only (see Important Warnings, page 2, #8).
Burning materials other than natural wood will shorten the
life of the catalytic combustor. Do not burn particleboard or
pressed logs using bonding agents as they can produce
conditions that will deteriorate metal or damage the catalyst. Green or uncured wood does not work well as fuel,
and can cause increased creosote buildups and plugging
of the catalytic combustor. The value of green wood as a
source of heat is limited. Do not overload or use kindling
wood or mill ends for primary fuel as this may cause overfiring. 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, AND THOSE AT HIGH ALTITUDES.
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 wellseasoned 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 smoke and very little
fire. Time is the most important 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 are several steps that should be taken
to ensure 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” (127 mm) diameter across or larger
should be split in half, three pieces if over 8 inches (203
mm), and four pieces when over a foot (305 mm)
across. If the tree fell 2 to 4 years ago, it still needs to
be cut, split, and seasoned for 6 to 24 months depending on the wood.
WOOD STORAGE
Wood to be seasoned 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 kept 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 16
MAINTENANCE
SMALL AREA PAINT TOUCH-UP
The stove body is painted with a quality hightemperature 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 grit 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 instead.
Mask off surfaces you do not want painted. Paint lightly
over the bare surface first 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 14 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 FROM FIREBOX!
Ashes can hold live embers for several days, and must
be disposed of with care.
WARNING: THE GASKETS MUST BE KEPT IN GOOD
CONDITION. DO NOT LEAVE THE STOVE BURNING
WITH THE DOOR OPEN OR AJAR. THIS WILL CAUSE
EXCESSIVE HEAT BUILD UP IN THE UNIT AND COULD
IGNITE SURROUNDING COMBUSTIBLES AS WELL AS
DAMAGE THE STOVE 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 MANUFACTURER'S WARRANTY).
SERVICING GLASS
CAUTION: BE CAREFUL NOT TO ABUSE DOOR
ASSEMBLY 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.
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 should be
placed 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
An 1/2" (13 mm) spun fiberglass gasket provides the
seal around the fuel door, a 1/8” x 1” (3.2 mm x 25.4
mm) flat woven gasket glass provides the seal around
the door glass and the side windows have a 1/8” (3.2
mm) thick lytherm gasket 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 fuel door gasket. The
(door) glass gasket has a self-adhesive backing. The
side window gasket does not require an adhesive (see
Replacement Parts, pages 23-24).
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 stove 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 facing
up. Remove the glass clips (by removing screws
holding clips), then carefully remove broken glass
one piece at a time (protective gloves are recommended).
2. Clean the area where the glass with gasket will be
installed.
3. Install new glass with gasket (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.
PAGE 17
MAINTENANCE
CREOSOTE FORMATION AND NEED FOR REMOVAL
What is Creosote - When wood is burned slowly, it
produces tar and other organic vapors, which combine
with expelled moisture to form creosote. The creosote
vapors condense in the relatively cool chimney flue of a
slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote
makes an extremely hot fire. Also, creosote deposits
tend to form in long runs of venting where gases become too cool prior to exhausting.
To inhibit the build up of creosote, adjust the primary air
control to a medium-high or high setting for a 10-minute
period each day. Do not attempt to burn out heavy
creosote accumulations in this manner. This must be
removed from the chimney 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 monthly
during the heating season to determine if a creosote
buildup has occurred. If creosote has accumulated it
should be removed to reduce the risk of a chimney fire.
Cleaning - Remove the catalytic combustor and open
the bypass damper prior to having your chimney
cleaned (should be done by a qualified chimney sweep).
See Maintenance Section, Catalytic Combustor, page
19 for instructions on removing catalytic combustor.
IMPORTANT: Make sure the bypass damper is in the
open position prior to chimney cleaning.
In the event of a chimney fire - Make sure the fuel door is
securely closed. Adjust the primary air control to the lowest
(most closed) setting. Call the fire department immediately.
After a chimney fire, the complete chimney system should
be checked by a qualified 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.
CATALYST REPLACEMENT
The normal expected life of a catalyst (catalytic combustor) is 10,000 to 12,000 hours if the appliance is operated correctly and proper fuels are used. If the catalyst has been deactivated, it should be replaced. Symptoms of deactivation include – noticeably darker smoke
exiting chimney and less heat output. If these symptoms
remain after normal maintenance or a major cleaning
(soak in heated vinegar/water solution, see page 19),
the catalyst, p/n 14000 will require replacement (also, if
the catalyst is broken and / or missing large pieces, it
should be replaced). Note: The catalyst does not need
to be glowing to be working. It will glow at times, but it
can work very effectively at temperatures well below the
1000° F level (at which it will begin to glow).
Stove Operation if Catalyst Is Deactivated – It is safe
to operate the appliance temporarily with a deactivated
catalyst (although it will be out of compliance with EPA
certification requirements). To operate, follow normal
lighting and refueling procedures as outlined in this
manual with one the following exceptions.
• During start-up, disregard catalytic temperature
probe reading to determine when to close bypass
damper control. Instead allow 20-25 minutes, then
close the bypass damper control.
• During refueling, disregard catalytic temperature
probe reading to determine when to close bypass
damper control. Instead allow 3-5 minutes after refueling, then close the bypass damper control.
CLEANING BLOWER INTAKE
If an optional blower kit (catalog #14M36) is installed,
the blower air intake requires cleaning at least once a
year to remove lint, dust, etc. If there are pets in the
dwelling, the intake should be cleaned at least twice a
year.
STOVE SEAMS
The stove body seams should be inspected at least
once a year. If any seams are found to be loose or
damaged, the seam should be cleaned with a wire
brush then resealed with furnace cement.
FIREBRICK
The firebrick should be inspected periodically and replaced if damaged (crumbling or excessively cracked).
PAGE 18
MAINTENANCE
CATALYTIC COMBUSTOR
Your stove has been designed with a catalytic combustor, which will improve the overall efficiency of your
stove. Removing the combustors for cleaning, inspection and reinstallation should be done at least once a
year. Cleaning the combustors helps reduce buildup of
ash and retarding chemicals. To clean the combustors,
a soft brush, vacuum cleaner, or pipe cleaner may be
used. Another effective cleaning method is to soak the
combustors in a hot cleaning solution of a 50/50 mixture
of white vinegar and distilled water for 30 minutes. Then
rinse by soaking in hot distilled water. After 15 minutes,
remove the combustors from the rinse water and gently
shake out excess water. It is unlikely that your will notice
a visible difference in the combustors after this cleaning
procedure. The combustor units are fragile in comparison to the rest of the stove - so handle with care.
Cleaning the combustors once a year, preferably when
your flue system is serviced, is sufficient for most users.
Reinstall the combustor set according to the following
instructions.
1. Disconnect pipe from stove flue outlet.
2. Looking down into stove flue, remove the bypassoperating rod and control arm set screws using an
Allen wrench.
6. Care should be taken to leave the gasketing in position when removing catalyst. This gasketing seals
the catalyst.
7. To reinstall, first remove the old stove cement from
the stovetop and top edges (use a wire brush). Reseal all gaps, including sides and base with a high
temperature cement or silicone gasket available
from your dealer.
Reinstall the catalyst housing and top. When tightening
down bolts on top, turn only a 1/4 turn and go to the next
bolt being careful not to overtighten as this will strip the
threads.
3. Remove the 2 bolts that hold the top in place (located on the underside center left and right side of
the top). Lift off the stovetop.
4. Remove the catalytic housing by removing the 4
bolts on the underside of the top.
5. The catalytic combustor is now visible under the
stainless steel shield. Although it may be covered
with a light ash, it should be relatively free of obstructions in the honeycomb cells.
PAGE 19
TROUBLESHOOTING
SMOKES OUT FUEL DOOR WHEN OPEN (see ✸✸✸✸)
1. The primary air control is closed.
2. The chimney is too cool. Set the primary air control
on "HIGH" with the bypass damper control "OPEN"
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 creosote fire. Strictly adhere to
maintenance requirements as outlined in this manual. If excess creosote has built up on the inside of
the firebox sides and door, burn a small hot fire at
intervals that are 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 min-
utes 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.
8. The combustor is plugged from engaging too soon
(remove combustor and clean, see Maintenance
section, pages 17-19).
BACKPUFFING (✸✸✸✸)
1. Downdraft in the chimney (may need a special
wind cap).
2. The catalytic combustor is too hot (avoid burning
soft, pitchy woods, or large amounts of smalldiameter wood).
3 The house is too air tight (ventilation is needed).
4. 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 primary air control).
3. Catalytic combustor not functioning.
4. 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).
DOES NOT PRODUCE ENOUGH HEAT (✸✸✸✸)
1. Using green or insufficiently cured wood.
2. Excessive draft.
3. High ceilings (heat rises quickly, 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 (305
square mm) 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 rate.
7. Combustor light off has not occurred.
DOES NOT MAINTAIN A FIRE (✸✸✸✸)
Soft wood does not burn as long or as well as seasoned
hardwood resulting in a short burn time.
1. Wood size too small. Burns at too rapid a rate.
2. The gasket seal on the fuel door, or glass is leaking
air. Repair or replace it if necessary.
3. There is an obstruction in the chimney
4. The stove was not up to normal operating tem-
perature before the bypass damper control was
pushed closed.
5. Excessive draft.
CATALYST PLUGGING
1. Burning materials that produce a lot of char and fly
ash. Do not burn materials such as garbage, gift
wrap, cardboard, etc.
2. Burning wet pitchy woods or burning large loads of
small diameter wood with the combustor in the operation position (without light-off taking place). Burn
proper fuel only. Do not close bypass until temperatures are high enough to initiate light off.
CATALYST DEACTIVATION
1. Burning large quantities of trash, pressure-treated
lumber or painted woods, etc. will deactivate the
catalyst. Burn proper fuels only. See Catalyst Re-
placement, page 18.
(✸✸✸✸) 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 Require-
ments, page 9).
PAGE 20
TROUBLESHOOTING
CATALYST SUBSTRATE CRACKING
1. Normal operation, as long as combustor remains intact. If cracking causes large pieces to
fall out, replace combustor.
2. Mishandling or abuse. Handle with care.
3. Warped housing (see Overfiring Damage on this
page).
CATALYST SUBSTRATE
1. Extreme thermal shock. Combustor is being
worked too hard.
2. Excessive draft. Correct installation (see Draft
Requirements, page 9).
CATALYST PEELING
Extreme Temperatures (over-firing) at combustor surface can cause the catalyst to peel. Some minor peeling
does not affect function. Severe peeling would close cell
openings and cause a plugging problem. If peeling is
severe, replace combustor. Do not overfire appliance.
See Overfiring Damage on this page.
TAR AND LIQUID CREOSOTE LEAKING FROM
METAL FLUE JOINTS
1. No chimney cap on chimney. Install cap.
2. Metal flue assembled improperly. Top flue sec-
tions should be inserted into lower flue sections.
DENCE SMOKE LEAVING CHIMNEY
1. W ater vapor (on cold still days water vapor may be
mistaken for smoke). W ater vapor is normal and
should be of little concern.
2. Wet, pitchy woods being burned. Burn dry seasoned
wood only.
3. Bypass in open position. Close bypass.
4. Combustor not functioning. See Catalyst Replace-
ment, page 18.
Overfiring Caused From Improper Installation
The venting system must satisfy the draft Requirements of
the appliance. The appliance is merely one component of a
larger system. The other equally important component is the
venting system, which is necessary for achieving the required
flow of combustion air to the fire chamber and for safely removing unwanted combustion byproducts from the appliance. If the venting system’s design does not promote these
ends, the system may not function properly, which may create performance problems as well as may be a safety hazard. To ensure that all installation requirements have been
met as outlined in the installation manual. The chimney
should be clean and in good repair. A draft test should be
performed to determine if the draft requirements of the appliance are being met. A draft gauge should read between .05
and .07 inches water column (W.C.I.). Excessive draft
(above .07 W.C.I.) will allow too much combustion air to be
pulled into the firebox, which results in hotter burns. Too little
draft (below .05 W.C.I.) will not allow enough combustion air
delivery to maintain a fire well or cause performance problems such as smoking (this may result in improper operation
of appliance, i.e. will not maintain fire well unless catalytic
bypass is left open, or with fuel door left open (see following -
Overfiring Caused From Improper Operation).
Overfiring Caused From Improper Operation
Operate this stove only as outlined in this manual. Never burn
the stove with the fuel door open or ajar. Do not operate this
stove with the air intake control in the "open" position 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 manual including
cleaning of flue and stove. Should the fuel door or glass
gaskets become frayed, worn or damaged, they should
be replaced with same size and type as original.
OVERFIRING DAMAGE
If the heater or chimney connector glows, the appliance is
overfiring. Other symptoms may include: Cracking, warping
or burning out of components, catalytic combustor may deteriorate, stove glass may develop a haze which will not come
off with cleaning, catalytic combustor housing grate may
crumble, etc. 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 necessary) if an overfiring condition is suspected:
Overfiring Caused From Improper Fuel
This appliance is approved for use with natural dry well seasoned wood only (consult your dealer for approved fuels in
your area). Do not burn garbage, particleboard scraps,
or pressed logs using bonding agents because they can
produce conditions that will deteriorate metal. Do not
overload or use kindling wood or mill ends as primary
fuel as this may cause overfiring. If any of the stove
body seams are found loose or damaged, the seams
should be cleaned with a wire brush then resealed with
furnace cement (this needs to be done annually, see
Stove Seams, page 18).
