Section 1.0 - Installation
When installed and operated as described in these instructions, the Osburn Model 1800 Bay Wood
Stove is suitable for use as a freestanding wood stove in either residential or mobile home installations.
The Model 1800 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 codes, local building and/or fire officials (or other authorities
having jurisdiction) should be contacted to determine what restrictions and installation requirements
might locally apply.
1.1 General Installation
1. Proper ventilation is required.
2. Do not connect this unit to any air distribution duct.
3. 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.

Note 1 : The floor protection at the back of the stove is limited to the stove’s required clearance
if such clearance is smaller than 8 inches (203 mm).
Note 2 : Only required under the horizontal section of the connector. Must exceed each side of
the connector by at least 2 inches (51 mm).
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 be
respected to allow vertical air circulation behind the shield. The shield must extend 20" (500 mm)
above the stove top and 18" (450mm) to each side of the stove (see graphic 1).

1.5 Chimney System
1.5.1 Definitions
For clarity, the following definitions should be used with respect to these instructions:
A chimney system consists of the connector off the top of the stove, and a chimney , which joins to
the connector and terminates outside the building envelope.
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.
1.5.2 Components
N OTE : All connector and manufactured chimney components must be L ISTED C OMPONENTS .
Masonry Chimneys must be Code Complying , and have a listed solid fuel burning liner (of
stainless steel or clay refractory construction).

14
1.5.2.1 Factory Built Chimney System
The following are the generic components required for a factory built chimney system for
residential installations:
Chimney – in the USA use a 6” diameter (152 mm) listed UL 103 HT chimney system and
components
Chimney – in Canada use 6” diameter (152 mm) listed ULC S629 chimney system and
components
M ANUFACTURED (M OBILE ) H OME C HIMNEY S YSTEM
In addition to the requirements of section 1.5.2.1 the following components are required for
manufactured (mobile) home installations:
A spark arrestor must be employed with the rain cap
Double walled connectors must be used instead of single walled connectors
For manufactured (mobile) home installations in the USA only and where the chimney system
has employed a solid pack chimney , a vented roof flashing must also be used.
1.5.2.3 Residential Close Clearances Chimney System
In addition to the requirements of section 1.5.2.1 the following components are required for
residential close clearances installations:
Double walled connectors must be used instead of single walled connectors

1.5.3.1 Connectors
The minimum connector diameter is 6" (152 mm). A minimum connector length of 4 ft (1.22 m) is
recommended for best results. Restrictions to stack gas flow (such as using more than two 90
o
elbows)
should be avoided and any horizontal runs should be kept to a minimum length, especially with short
chimneys. The connector pipe, which joins the unit to the chimney, may be of either single or double
walled construction. Connector pipe should be a minimum of 24-gauge steel.
The connector pipe itself must not pass through any combustibles, nor may it pass through non-
combustibles and into 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.
Install sections of single wall or double wall connector between the stove and the chimney. Secure all
connector pipe joints with a minimum of three sheet metal screws. All connector and factory built
chimney pipes must be installed with the male or crimped end down to prevent creosote dripping
outside the joints. If non-telescopic sections are to be used, they must be cut to length, allowing for
overlap. Use three (3) screws to attach the connector section to the flue collar of the stove. Listed
double walled connectors should be installed in accordance with the vent manufacturer’s installation
instructions.
Figure 1.2 - Joints in Chimney System
1.5.3.2 Chimney Systems
The minimum chimney size is 6" (152 mm) in diameter. The minimum overall height of the chimney
system, measured from the base of the appliance is 12' (3.66m). Existing masonry and metal chimneys
should be inspected to check for deterioration and to determine if they meet the minimum installation
requirements; they should be upgraded if necessary. In Canada, masonry chimneys must have or use a
ULC S635 listed Class III liner in chimney systems that are not ULC S629 listed. Similarly in the
USA a UL 1777 listed refractory or metallic liner must be used. At the point of penetration through the
roof to the outside of the building envelope, the chimney must extend at least 3' (914 mm) above the
roof and at least 2' (610 mm) above the highest point within an area of 10' (3 m) of the chimney (see
Figure 1.3).
Follow CSA Standard B365-M91 for methods and precautions to be employed when connecting the
stove to a masonry chimney, and for installing thimbles (wall penetration assemblies) when the
connection from the stove to the masonry chimney is made through a combustible wall.

16
When connecting to a factory built chimney, ensure that it is installed according to the manufacturer's
listed instructions. If using an existing chimney, inspect and clean the chimney if required (this should
be done by a licensed chimney sweep or a qualified professional).
Figure 1.3 – Chimney height
1.5.3.3 Exterior Chimney
Chimneys constructed outside of the home on an exterior wall should be avoided if possible, especially
in colder climates. Exterior chimneys may not draft well and in fact may down draft (reverse flow) due
to the difficulty in heating them up to operating temperature while trying to evacuate the stack gases.
All else being equal, cooler chimneys will have less draft than hotter ones; this may lead to creosoting
and poor performance. If an exterior chimney is used to remove the stack gases 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 chimney. For efficiency and safety reasons the stove must not be installed with an
insulated chimney connected directly to the appliance.

17
1.5.3.4 Draft
Your Osburn stove will attain its best performance if installed with a chimney system that has proper
draft. (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, and 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. (See Table 2.2). Drafts of less than .03" w.c. will cause
operation difficulty while too much draft (greater than .10" w.c.) will result in over-firing of the stove.
This can result in excessive operating temperatures. If this is the case, a manual damper may be
installed in the vertical connector pipe to help reduce excessive draft.
Figure 1.4 Connection to a Masonry Chimney (Exterior Shown)
1.5.4 Typical Types of Chimney Systems
There are basically two types of chimney systems; one employs an existing masonry chimney,
while the other employs a manufactured or factory built chimney. In either system the chimney
may be of an interior or an exterior type. The following illustrations are provided to
demonstrate the basic components required for a proper and safe installation. The components
identified may not appear exactly as those purchased – the manufacturers’ installation
instructions and specified clearance distances 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.

Section 2.0 - Operation
2.1 Safety Information
1. This stove is designed for safe operation
W HEN B URNING C ORDWOOD O NLY . Altering or
modifying the unit or installation without proper authorisation will void the certification,
warranty, and safety listing, and may result in a safety hazard.
2. For safety reasons, never leave the unit unattended with the door open or ajar. An open
door, and especially a door partially open or cracked, if left for longer than required for
good ignition can potentially result in unsafe chimney temperatures, and if left
unattended in hot embers or ignited fuel falling out of the unit. Prolonged door open
operation is not necessary provided the unit has been properly installed and dry kindling
is used to start the fire.
3. Do not abuse the unit, either by over firing or by using wood or combustibles with salt
content, or harmful chemicals. Misuse is not covered by warranty.
4. Even though your Osburn has been specifically designed and tested to prevent smoke
spillage, always open the door slowly as this will minimise the likelihood of smoke
spillage or a back draft of flame or smoke into the room.
5. Never use gasoline type lantern fuel, kerosene, solvents, charcoal lighter fluid, or
inflammable liquids to start or "freshen" a fire in the stove. Keep all such liquids well
away from the stove while it is in use.
6. All stove surfaces become very hot during operation. Care is needed, especially with
children, to avoid contacting these surfaces.
7. Do not elevate the fire by means of grates.
8. C
AUTION : D O N OT O VER F IRE T HIS H EATER . Do not burn fuel in the stove at a rate
higher than that which will cause the ember bed level to exceed half the door opening
height. If the door handle of the stove becomes excessively hot to the touch, consider
this to be an indication of over firing. Over firing can result in a safety hazard and can
permanently damage the stove and chimney. This damage is not covered by the
warranty.
9. Although the ceramic glass is extremely durable under any normal use, a few
precautions are required. Do not attempt to push logs further into the fire by using the
door, as the glass may break if any solid object heavily contacts it.
10. Never operate the stove with the door open, or cracked slightly open, except briefly

20
during the lighting operation, and during refuelling. Leaving the door open continuously
could seriously overheat the chimney and adjacent combustibles. Do not operate the
stove if there is an abnormal air leakage into the stove, such as through deteriorated
gaskets or cracked or broken glass. Do not operate the stove without a door gasket.
Leakage can result in overheating, or in very airtight homes, could possibly cause
smoking into the room. Smoke may contain carbon monoxide, which is poisonous, and
in sufficient quantities is a health hazard.
2.2 Fuel
1. Fuel for the stove must not be stored closer than the required clearances to combustibles
and not in the space required for charging and ash removal.
2. Your Osburn stove is designed to burn
C ORDWOOD F UEL O NLY . Do not burn coal,
charcoal, or trash in the unit. Highly flammable items such as trash may ignite creosote
in the chimney, resulting in a chimney fire. Never burn salt wood, beach wood,
chemically treated wood, or wood removed from salt water, since the deposits left will
deteriorate the firebox. Damage caused by chemicals or salt is not covered under
warranty.
3. Seasoned dense wood is recommended. Wood should be air dried in a covered
ventilated area for six months to a year or more. This reduces the moisture content of
the wood, resulting in better stove performance. Wood species with moisture content of
20% or less are ideal. Dry seasoned wood can be distinguished from green wood by the
checks or cracks in the ends.
4. Wet or green wood will tend to cause the fire to smoulder, producing large amounts of
creosote. Creosote buildup could result in a chimney fire. This wood will also prove
difficult to keep burning properly, and fires will tend to go out. Green wood produces
very little heat, and sometimes causes customers to think that the stove does not work.
If you must burn wet wood, use only small amounts mixed with dry wood.
5. Decayed wood or low-density wood has very little energy content or heating value, and
will not burn satisfactorily for long periods of time.
An example of the energy values of some common wood fuels is given in Table 2.1
For recommended wood sizes, refer to the specifications.
