*Why is the BTU indicated on the EPA label smaller than the one advertised?
You will notice a difference between the BTU output as indicated on the unit’s white EPA label affixed to the glass and the BTU as
advertised on our web site and/or product literature. The maximumBTU output we advertise for this unit is what will beobtained
with a full load of seasoned cordwood inserted inside the firebox. The EPA output, on the other hand, is what has been obtained
during emissions testing. The EPA test procedure requires that a special type of wood be used and positioned inside the firebox in a
manner that does not represent the way the firebox volume would normally be utilized using seasoned cordwood. The EPA test load
is typically much smaller. Hence, the BTU as per the EPA label is reduced. The BTU output that should be considered by anormal
user is the one we advertise for seasoned cordwood.

SECTION 1.0 - INSTALLATION
When installed and operated as described in these instructions, the Osburn 1500 wood stove is suitable for
use as a freestanding wood stove in residential installations. The Osburn 1500 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.
Note that this heating unit must serve as a supplementary heat source. An alternate 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 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.
•ASOURCE OF FRESH AIR INTO THE ROOM OR SPACE HEATED SHALL BE PROVIDED WHEN REQUIRED.

CODES FOR USE WITH SOLID FUEL,OR TO A LISTED FACTORY BUILT CHIMNEY SUITABLE FOR USE WITH SOLID
FUEL.
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 functionsby 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. Refer to Figure 1.3 for a diagram of each of the measures A through C.

1.3.1 Reduced clearances using shielding
You may decrease the clearances by installing heat radiation shields between the walls or the
ceiling and the stove. These heat radiation shields must be installed permanently, and can include
sheet metal, a rigid non-combustible sheet or a masonry wall.
Clearances of not less than 1" (25 mm) and not more than 3" (76 mm) between the bottom of the
shield and the floor and not less than 3" (76 mm) between the top of the shield and the ceiling must
berespected to allow vertical air circulation behind theshield.The shield mustextend20"(500 mm)
above the stove top and 18" (450mm) to each side of the stove (see Graphic 1).
Following the installation of such a heat radiation shield, the clearances mentioned on the stove
certification plate may be reduced as stated in the following table.

1. The stove must be bolted to the floor (secure the unit by prying out the two plastic plugs in the
pedestal, and installing the two 3/8" x 3-1/2" (9.8mm x 88.9mm) lag bolts through the holes
provided).
2. The unit must be provided with outside combustion air. Consult your Osburn dealer for
information about genuine parts needed for mobile home installations (genuine part numbers
#AC02080 & AC02090). See pictures below for reference.
3. Clearance from the top of stove to an unprotected ceiling should be a minimum of
52” (1321mm).

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:
•DONOTFILLANYFRAMEDSPACEAROUNDTHEFACTORY-BUILTCHIMNEYWITH
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

•DO NOT CONNECT THIS UNIT TO A CHIMNEY SYSTEM SERVING ANOTHER
APPLIANCE.
•DO NOT CUT RAFTER OR CEILING JOISTS WITHOUT FIRST CONSULTIN 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.

14
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
code-approved 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 whish is too large may also cause draft
problems. In fact, a large chimney will be harder towarm-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 orother 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 chimneyrequires regular inspection in order to insure that it
is not obstructed, thus blocking the draft. It should be cleaned when necessary.

Thewaytoinstallyourchimneymayvaryfromonechimneymanufacturertoanother.Theinstructions
contained in this manual are based on the recommendations of chimney manufacturers whose
products are sold at many North American retailers of wood stoves and related heating accessories.
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
•Anadequatenumber ofwallbands(oneforevery8feet of chimney, excludingtheroofportion)
•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 (24 gauge)
•A 90o elbow
Typical installation through the wall

16
FIGURE 2.2.1 (A) Typical installation through the wall
1- Start by positioning your stove where you would like it to go, taking into account the minimum
clearancesto combustiblematerial. You will then be able todetermine where thechimneywill
pass through the wall. You will probably have to adjust the stove position slightly to ensure
that your chimney will run between the studs. You can use a stud finder to locate the studs.
Use a spoke saw or jig saw to cut a hole, remembering that you need to maintain a clearance
of 2 inches between the chimney and any combustible materials. For concrete walls, cut a
hole slightly larger than the outer diameter of the chimney.

17
2- Once the opening completed, you need to frame in the area to allow for the installation of a
wall thimble. A wall thimble is not required for installations through concrete walls.
3- You must first secure the wall thimble into the exterior wall surface. Then, do the same inside
and fasten the trim plate.
4- Then, from outsidethe building, slideashort chimney length(attached to the tee)throughthe
wallthimble.The chimney must extendat least 3 inchesinto the living spacewhereitattaches
to the stove pipe.

18
5- You can now install the wall support. Simply slide the wall support up to the tee, ensuring that
the adapter on the support engages with the female coupler on the bottom of the tee. When
the wall support is level and properly positioned,youcanuse lag boltsto secure itintothe wall
studs. To complete the installation, install an insulated tee plug below the wall support.
6- You can start to add chimney sections. We recommend that you also use locking bands to
secure all connections. You will need to secure the chimney to the house using wall bands.
Wall bands wrap around the chimney and then attach to the wall. Install the first one 3 feet
abovethewall support. Then, you willneed anotherbandforeach8feetofchimney. Note: if
your chimney must be installed through your soffit, install a roof flashing above and
finishing plate below where the roof is cut. Consult the following section called
“CEILING SUPPORT SYSTEM” for more details.
7- Authorities require that the chimney extend not less than 3 feet above the highest pointwhere
it passes through the roof of a building and not less than 2 feet above any portion of the
buildingwithin10 feet. If the chimneyextends more than 5feetabove the roofdeck,roofguys
with telescoping legs and draw bands are required.

19
8- Finally, twist on your rain cap and you can head back inside.
9- You are now ready to connect your chimney to your stove. Simply install the inter-connecting
stovepipebetween thestovepipe adapter and thestove.Youcanfollowtheinstructionsinthe
following section (section 2.3) of this manual called « CHIMNEY CONNECTOR».
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
•A chimney cap with spark arrester (for manufactured (mobile) home installation)
•Roof guys (if necessary)
Stove pipe
•Suitable lengths of stove pipe (24 gauge)
