SECTION 1.0 - INSTALLATION
When installed and operated as described in these instructions, the Osburn 2000 wood stove is
suitable for use as a freestanding wood stove in residential installations. The E.P.A Osburn wood
stove is not intended for installation in a bedroom.
In Canada, the CSA B365 Installation Code for Solid Fuel Burning Appliances and Equipment and
the CSA C22.1 Canadian National Electrical Code are to be followed in the absence of local code
requirements. In the USA, the ANSI NFPA 70 National Electrical Code and NFPA 211 Standard for
Chimneys, Fireplaces, Vents and Solid Fuel-Burning Appliances are to be followed in the absence of
local code requirements.
In addition to the national installation and/or local building codes, fire officials (or other authorities
having jurisdiction) should be contacted to determine what restrictions and installation requirements
might apply locally.
1.1 GENERAL INSTALLATION
CAUTION:
• MIXING OF APPLIANCE OR FLUE SYSTEM COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING THE
DIMENSIONAL SPECIFICATION OF COMPONENTS MAY RESULT IN HAZARDOUS CONDITIONS. WHERE SUCH
ACTION IS CONSIDERED, THE MANUFACTURER SHOULD BE CONSULTED IN THE FIRST INSTANCE.
• DO NOT CONNECT THIS UNIT TO ANY AIR DISTRIBUTION SYSTEM.
• CRACKED AND BROKEN COMPONENTS, e.g. GLASS PANELS OR CERAMIC TILES, MAY RENDER THIS
INSTALLATION UNSAFE.
• A SOURCE OF FRESH AIR INTO THE ROOM OR SPACE HEATED SHALL BE PROVIDED WHEN REQUIRED.
• INSTALL A SMOKE DETECTOR IN THE ROOM WHERE THE STOVE IS LOCATED
• CONNECT THE STOVE ONLY TO A LINED MASONRY CHIMNEY CONFORMING TO NATIONAL AND LOCAL
BUILDING CODES FOR USE WITH SOLID FUEL, OR TO A LISTED FACTORY BUILT CHIMNEY SUITABLE FOR
USE WITH SOLID FUEL.
This heating unit must serve as a supplementary heat source. An alternative heat source should be
available in the home if needed. The manufacturer cannot be responsible for additional heating
costs associated with the use of an alternative heat source.
It is highly recommended that the user buys this product from a retailer who can provide installation
and maintenance advices.

1.1.2 Door overlay installation
In order to complete the assembly of your freestanding Osburn 2000 wood stove, you need to
install the door overlay. See table 1.1.3 below for installation instructions :
1- Position the overlay on the door frame and fix it in place from behind using the 4 screws.
Note: It is not necessary to remove the glass or any other component to install the overlay.
Table 1.1.3 Door overlay installation

5
1.2 POSITIONING THE STOVE
It is very important to position the wood stove in an area that will favour the most efficient heat
distribution throughout the house. The stove should therefore be installed in the room where the
most time is spent, and in the most spacious room possible. Recall that wood stoves produce
radiating heat, the heat we feel when we are close to a wood stove. A wood stove also functions by
convection, that is through the displacement of hot air accelerated upwards and its replacement with
cooler air at the floor level. The stove’s convection effect is facilitated by the installation of a
blower.
1.3 CLEARANCES
Clearances to any combustibles when measured directly from the floor protector to the ceiling must
be a minimum of 84" (2134 mm). Clearances to any combustibles when measured directly from the
front of the stove must be a minimum of 48" (1219 mm). The stove must also be placed so as to
maintain the minimum clearances to combustible walls specified for each type of connector used.
See Table 1.3 below for all clearance measures

1.3.1 Reduced clearances using shielding
You may decrease the minimum clearances to combustible materials by installing heat radiation
shields between the walls or the ceiling and the stove. Those heat radiation shields must be installed
permanently, and must be made of a heat-resistant or heat-tolerant material. Consult the table below:

Convert specification to R-value:
k-factor is given with a required thickness (T) in inches: R=1/k x T
C-factor is given: R=1/C
Example:
If the floor protector is 4” brick with a C-factor of 1.25 over 1/8” mineral board with
a k factor of 0.29 the total R-value of the system is:
4” brick C=1.25, R=1/1.25=0.8
1/8” mineral board K=0.29, R=1/0.29 x 0.125=0.431
Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231
Total R is greater than 1.0, the system is acceptable.

1.4 FLOOR PROTECTOR
If the stove is to be installed on top of a combustible floor, it must be guarded by a non-combustible
material extending at least 18” (300mm) from the front and 8” (200mm) from the sides and the back
of the firebox., as shown in Figure 1.4 below.
Please note that a floor protection is required with the pedestal models for spark and ash shielding,
but not for limiting floor temperatures from the radiant heat of the stove. The stove was designed and
safety tested so that without any protection, the floor would not overheat.
Please refer to local building codes for suitable floor protection materials.

SECTION 2.0 CHIMNEY (FLUE SYSTEM)
2.1 DEFINITIONS
For clarity, the following definitions should be used with respect to these instructions:
• A chimney system consists of a connector off the top of the stove, and a chimney, which
attaches to the connector and terminates outside the house.
• A chimney can be a masonry chimney (of masonry construction with an inside liner), or a
factory built chimney.
• A factory built chimney can be a double walled chimney (two concentric pipes with
insulation - sometimes referred to as an insulated solid pack) or an air cooled chimney
(three concentric pipes, with insulation between the first and second pipes, and air between
the second and third pipes).
• A single walled connector is a single pipe.
• A double walled connector has two concentric pipes, no insulation, and is an air cooled
connector.
2.2 CHIMNEY
CAUTION:
• DO NOT fill any framed space around the factory-built chimney with insulation or any other
material. Insulation placed in this area could cause adjacent combustibles to overheat.
• Do not use makeshift compromises during installation as they may be safety hazards, and a
fire could result.
• Do not connect this unit to a chimney system serving another appliance.
• Do not cut rafters or ceiling joists without first consulting a building official to ensure
structural integrity is not compromised.
Your wood stove may be hooked up with a factory built or masonry chimney. If you are using a
factory built chimney, it must comply with UL103 (USA) or ULCS629 (Canada) standards. It must
therefore be a 6” (152mm) HT Type (2100°F) chimney. It is extremely important that it be installed
according to the manufacturer's specifications. The manufacturers’ installation instructions and
specified clearances should always be followed in accordance with local and national installation
codes. In Canada the CSA B365 and the CSA C22.1 installation codes are to be followed. In the
USA the ANSI NFPA 70 and ANSI NFPA 211 installation codes are to be followed.

10
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the Building Code. It must be lined with fire clay bricks, or clay tiles, sealed
together with fire cement, or have a listed solid fuel burning stainless steel liner. Round chimneys
are the most efficient.
The interior diameter of the chimney should be identical to the stove's smoke exhaust. A chimney
which is too small may cause draft problems, since it may not have the required volume to properly
evacuate the quantity of smoke resulting from the combustion. A chimney which is too large may
also cause draft problems. In fact, a large chimney will be harder to warm-up and may not reach high
enough temperatures to create a proper draft effect. Note that it is the chimney which creates the
draft effect, not your stove. Your stove's performance is therefore directly dependent on an
adequate draft from your chimney.
The following recommendations may be useful for the installation of your chimney:
• Do not connect your stove to a chimney serving another appliance.
• The chimney must rise above the roof at least 3' (0.9 mm) from the uppermost point of
contact. See Figure 2.2.
• The chimney must exceed any part of the building or other obstruction within a 10' (3.04 m)
distance by a height of at least 2' (0.6 m). See Figure 2.2.
• The minimum overall height of the chimney system, measured from the stove top to the
exterior termination cap of the chimney should be at least 12' (3.66m). A chimney which is
too short may lack the “tunnel effect” required to obtain a proper draft.
• Installation of an interior chimney is always preferable to an exterior chimney. Chimneys
constructed outside of the home on an exterior wall should be avoided if possible, especially
in colder climates. The gas which circulates into an interior chimney will cool more slowly,
thus reducing the build-up of creosote and the risk of flue fires.
• All else being equal, cooler chimneys will have less draft than hotter ones. This problem will
be amplified if the chimney is excessively long. A chimney which is excessively long may be
very hard to warm-up due to its higher volume. A cool chimney may even down draft
(reverse flow) due to the difficulty in heating it up to operating temperature while trying to
evacuate the stack gases.
• If an exterior chimney is used, the best results will be obtained by using a connector
vertically off the unit to the highest possible point before elbowing off horizontally to the
exterior chimney. For efficiency and safety reasons the stove must not be installed with an
insulated chimney connected directly to the appliance.
• Using a fire screen at the extremity of the chimney requires regular inspection in order to
insure that it is not obstructed, thus blocking the draft. It should be cleaned when necessary.

2.2.1 Step by step installation of your factory-built chimney
The way to install your chimney may vary from one chimney manufacturer to another. For installation
instructions, we advise you to consult your chimney manufacturer whose products are sold at many
North American retailers of wood stoves and related heating accessories.

12
Typical installation through the wall
Wall support system
If your chimney must rise along an outside wall, you need to connect it to your stove through an
adjacent wall. For this type of installation, the following items are normally required :
Chimney
• Suitable lengths of chimney (enough to go up to your roof)
• An adjustable wall support
• A wall thimble
• An adequate number of wall bands (one for every 8 feet of chimney, excluding the roof portion)
• A stove pipe adapter
• One insulated tee & plug
• A roof flashing kit (if necessary)
• A chimney cap.
• Roof guys (if required)
Stove pipe
• An adequate number of stove pipe sections.
• A 90o elbow

13
Typical installation through the ceiling
Ceiling support system
If your chimney must rise inside the house and go through the ceiling, you need to connect it to
your stove at the ceiling level. For this type of installation, the following items are normally
required :
Chimney
• An adequate number of chimney sections (enough to go up to your roof)
• A ceiling support kit with stove pipe adapter
• An attic insulation shield
• A roof flashing kit
• A chimney cap
• Roof guys (if necessary)
Stove pipe
• Suitable lengths of stove pipe
FIGURE 2.2.1 (B) Typical Installation Through the Ceiling

14
2.2.2 Typical installation through an existing masonry chimney
You can also install your stove using your existing masonry chimney. To do so, follow the
guidelines below. You may want to use a factory-built thimble, on construct your own brick thimble.
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the Building Code in your region. It must normally be lined with fire clay bricks,
metal or clay tiles sealed together with fire cement. (Round flues are the most efficient).

2.3 CHIMNEY CONNECTOR
Your chimney connector (commonly called stove pipe) and chimney must have the same
diameter as the stove’s exhaust outlet. The stove pipe must be made of aluminized or cold roll
steel with a minimum 24-gauge thickness (0.021" or 0.53 mm). It is strictly forbidden to use
galvanized steel.
The following recommendations may be useful for the installation of your chimney connector:
• Your chimney connector should be assembled in such a way that the male end (crimped)
faces down to prevent creosote dripping outside the joints. Attach each of the sections to one
another with three equidistant metal screws. Also use three equidistant metal screws to
attach the connector to the stove’s exhaust collar. See Figure 2.3 (A) and Figure 2.3 (B).
• The pipe must be short and straight. All sections installed horizontally must slope at least ¼
inch per foot, with the upper end of the section toward the chimney. See Figure 2.3 (B).
• To insure a good draft, the total horizontal length of the connector should never exceed 8' to
10' (2.4 to 3.04 m). In the case of vertical installation, the total length of the connector can
be much longer and connected without problem to the chimney at the ceiling level.
• There should never be more than two 90 degrees elbows in the whole connector and chimney
system. Never start with a 90oelbow. Always go up vertically for at least 2 feet from the flue
spigot before using a 90oelbow.
• The connector must not pass through any combustible material, nor may it pass through a
concealed space (such as an attic, roof space, or closet). If passing through a wall, ceiling, or
into a masonry chimney, use either chimney components listed for that specific use, or means
acceptable to local authorities having jurisdiction over the installation.
• Furthermore, installation of a draft damper is not recommended. Indeed, with a controlled
combustion wood stove, the draft is regulated upon intake of the combustion air in the stove
and not at the exhaust.

2.4 DRAFT
Your Osburn 2000 stove’s performance will be optimised if it is installed with a chimney (flue)
system that provides an adequate draft. The draft is the force that moves air from the appliance up
through the chimney and is predominantly affected by the height and diameter of the chimney, as
well as the stack temperatures of the stove. If you test the draft using a pressure gauge, the reading
should be between .05 - .07 inches of water column (w.c.) at a medium-high fire. A draft measure of
less than .05" w.c. will cause operational difficulties while too much draft (greater than .10" w.c.)
will result in over-firing of the stove. This can result in excessive operating temperatures.
2.5 OUTSIDE COMBUSTION AIR
It is recommended to install 5’’ outside air intake in the room where the stove is located or nearby.
The following are signs that a fresh air kit may be required:
• Your stove does not draw steadily, smoke rollouts occur, wood burns poorly, or back-draft
occurs whether or not there is combustion present.
• Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances,
smell, do not operate properly, suffer smoke rollouts when opened, or back-draft occurs
whether or not there is combustion present.
• Opening a window slightly on a calm (windless) day alleviates any of the above symptoms.
• The house is equipped with a well-sealed vapour barrier and tight fitting windows and/or has
any powered devices that exhaust house air.
• There is excessive condensation on windows in the winter.
• A ventilation system is installed in the house.
