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 andthe 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.
CLEARANCES TO COMBUSTIBLES
1.2.1 Canada and the U.S.A.
Clearances to any combustibles when measured directly out from the front and up from the top of
The stove must be a minimum of 48" (1219 mm). The stove must also be placed so as to maintain the

1.3 Residential Installation Instructions
Choose a location for the unit which meets the minimum clearances to combustibles (see Table 1.1). For
other than masonry chimneys determine if the factory built chimney will pass between the ceiling joists; if
not, choose a new location so that it will, while still maintaining the minimum clearances.
1. Mark the location for the floor protection‡(if required) as noted in Figure 1.1.
Note:If outside air for combustion is to be used it should be provided for at this time. This requires that the
Osburn Fresh Air Kit Wood (#OA10500) be installed (refer to the installation instructions which are
provided in the outside air kit. Install the unit.
Floor Protection Requirements (for combustible floors)
If the stove is to be installed on top of a combustible floor it must be guarded by a non-combustible
material extending beneath the heater and to the front and sides as indicated in Figure 1.1, or to the nearest
permitted combustible material. Floor protection must extend beneath, and 2” (51 mm) to the sides of a
horizontal connector if one has been used.
Please note that floor protection is required under the pedestal models for spark and ash shielding, but not
for limiting floor temperatures fromthe radiant heat of the stove. The stove was designed and safety tested
so that without any protection the floor would not overheat even under over firing conditions. Please refer
to local codes for suitable floor protection materials.

7
1.4 Manufactured (Mobile) Home Installations – Additional Requirements
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.
3. Clearance from the top of stove to an unprotected ceiling should be a minimum of
52” (1321mm).
4. A pipe shield must be used on the double wall connector. Part # OA10035 shield. See
installation instructions with shield.
Note:For manufactured home installations in the USA, the stove must be grounded to the frame of
the home using a # 8 ground wire with approved terminations and star lock washers.
CAUTION: THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR,WALL,CEILING /
ROOF MUST BE MAINTAINED.
CAUTION:DO NOT INSTALL IN ASLEEPING ROOM.
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
NOTE:All connector and manufactured chimney components must be LISTED COMPONENTS.
Masonry Chimneys must be Code Complying, and have a listed solid fuel burning liner (of stainless
steel or clay refractory construction).

8
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
MANUFACTURED (MOBILE)HOME CHIMNEY SYSTEM
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 General Installation Requirements
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 AFIRE COULD RESULT.
DO NOT CONNECT THIS UNIT TO ACHIMNEY SYSTEM SERVING ANOTHER APPLIANCE.
DO NOT CUT RAFTERS OR CEILING JOISTS WITHOUT FIRST CONSULTING ABUILDING OFFICIAL TO
ENSURE STRUCTURAL INTEGRITY IS NOT COMPROMISED.

9
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 90oelbows)
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 haveoruse 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 connectingthe 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.

10
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 ifrequired (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 exteriorwall 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.

11
1.5.3.4 Draft
Your Osburn stove will attain its best performance ifinstalled 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 WHEN BURNING CORDWOOD ONLY. 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 ofsmoke 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. CAUTION:DO NOT OVER FIRE THIS HEATER.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 during

14
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 CORDWOOD FUELONLY. 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,andwill
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.
Table 2.1 Common Heating Values of Cordwood
Hardwoods Million Btu/Cord Softwoods Million Btu/Cord
Birch 23.6 Douglas Fir 20.6
White Oak 28.3 Hemlock 17.1
Alder 17.6 Jack Pine 18.4

15
2.2.1 Simple Wood Moisture Test
Add one large piece of wood to the top of an established fire. If it starts to burn on three sides.
Within one minute, it is dry and seasoned and right for burning. If it turns black and starts to
burn.
In three minutes, it is damp. If it turns black and does not start burning until after five minutes, it
Is green and wet. If it hisses at any time the wood is soaked and will not burn until excess
moisture is boiled away.
2.3 Notes About First Firing
Before firing ensure that the room is well ventilated. Curing the paint is recommended to preserve
the best quality finish. Heating the stove up too intensely on the first fire will dull and lighten the
colour on overheated areas, and cause smoke and odour to be emitted into the room. To cure the
paint, the first two fires should be burned for only about twenty minutes each.
Allow the stove to get warm only but not hot, i.e. 250oF (120oC) as measured by a stovetop
thermometer, and allow the stove to cool down. Light a third fire and burn it for about forty
minutes to 450oF (230oC) or less. Once again cool the stove to room temperature, then operate it
according to the following instructions. This extra care will result in a more durable, and uniform
finish.
2.4 Lighting A Fire
1. Place enough crumpled balls of newspaper or other paper into the stove to cover the
bottom of the firebox.
2. Place small dry kindling on the crumpled paper.
3. Place larger dry kindling on top of the small kindling.
4. Open the draft control fully to the right (located on the front of the stove, Figure 2.1)
5. Light a fire at the bottom of the crumpled paper and close the door. If the fire tends to go
out, momentarily hold the door slightly ajar to fan the fire. As soon as the fire catches hold,
close the door.
6. Ideally the large kindling should be burned until a thick bed of red embers is obtained. At
that point, add cordwood fuel and continue to operate the draft control wide open until the
fire is well established. Once the firebox is hot, the draft control can be partially closed by
moving the handle to the left to adjust the intensity of the fire.

16
Use Table 2.2 to adjust the draft control to the desired burn rate:
Burn Rate Draft Setting
Low Move Control against the L.H. side.
Medium Low Move Control right by 9/16” – 1” (14.3 – 25.4mm) from closed position.
Medium High Move Control right by 7/8” - 1 3/4” (22.2 – 44.5mm) from closed
position
High Move Control against the R.H. side
Table 2.2 Draft Settings
Closing the draft control down too soon will lower combustion efficiency, and may result in creosote
build-up in the chimney (which could lead to a future chimney fire).
CAUTION:THE ADJUSTMENT RANGE SHOULD NOT BE ALTERED FOR INCREASED FIRING FOR ANY REASON.
Figure 2.1 Draft control
2.5 Maintaining The Fire
Your Osburn stove will work best if a thick bed of hot embers is maintained in the bottom of the
firebox, and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is
largely related to establishing a hot ember bed, and hot firebox temperatures. The quicker the stove
and fuel get up to operating temperature, the better. A small intense fire is preferred to a large
smouldering fire, both to improve combustion efficiency and to reduce the amount of creosote
emitted. The best performance will be obtained by adding relatively small amounts of fuel to a
well established ember bed, and then operating with the air inlet control open long enough to
achieve a hot fire. Cordwood should be placed with air in between individual pieces. Use a poker
to make an air channel in the embers below the wood, this will allowair to flow under the wood for

17
a more efficient burn.
Extended burn times can be accomplished by first operating the stove on a full load with the air
inlet controls wide open. Once the fire is well established, and the moisture has been driven out of
the wood, reduce the air control to a low setting. The unit should then burn cleanly without
smoldering. If the fire smolders without flame, re-establish a hotter fire before moving the air
control to the low setting. A yellow flame burning in the top of the firebox is a good indication of a
clean efficiently burning fire.
Refuelling technique is important for good performance. The best efficiencyand performancefrom
your stove can be achieved by adding partial loads of fuel and allowing them to get up to operating
temperature before adding additional fuel. Adding a large amount of fuel at one time will increase
the time required to get the fuel up to its ignition temperature, and an extended time to reach
optimal performance. When refueling, open the air control or hold the door partially open 1” (25
mm) or less long enough (less than 5 minutes) so that the fire has well established flames. When
refuelling, care is required to ensure that fuel or embers do not fall out of the door opening. The
unit will burn at about 2.0 to 2.5 lb/hr (.9 to 1.1kg/hr) at its minimum setting; approximately 20 to
25 lbs (9 to 11.3kg) of wood are required for an extended burn.
2.6 (Optional) Fan Installation and Operation
1. Allow the stove to reach operating temperature (approximatelyone hour),beforeturning on
the fan, since increased airflow from the fan will remove heat and affect the start-up
combustion efficiency.
NOTE: ENSURE THE FAN CORD IS NOT IN CONTACT WITH ANY SURFACE OF THE STOVE TO
PREVENT ELECTRICAL SHOCK OR FIRE DAMAGE.DO NOT RUN CORD BENEATH THE STOVE.
2. Turn the fan on or off with the two speed switch located on the fan housing. The switch
settings are High, Off, and Low.
3. Follow the installation instructions that are with the fan kit #OA10510.
Section 3.0 - Maintenance
3.1 Care And Cleaning
Clean the stove frequently so that soot, ash and creosote do not accumulate. Do not attempt to
clean the stove, glass or door when the unit is hot. Special care must be taken with Gold surfaces in
order to maintain the finish at its original brilliance. Do not use an abrasive glass cleaner which
will scratch the glass or gold finish. Use only a soft clean damp cloth on the door, since some
cleaners may remove the plating or paint.

18
3.1.1 Glass Cleaning
Under normal operation the glass is designed to stay clean. Glass cleaning may be required when
burning damp wood and/or when burning slow fires. In general if the glass is not staying clean
then the unit is being under fired. Dirty glass may be self cleaned by burning a hot fire (i.e. dry
wood and opened draft controls) for a couple of hours. Good burning techniques will result in
clean glass.
Hand clean the glass only when the fire is out and the stove is cold. A light film can usually be
cleaned with paper towel and water. If heavy cleaning is required, a ceramic glass cleaner or polish
is recommended, and should be rinsed off with water for best results.
3.2 Ash Removal Using Ash Drawer
CAUTION:ASHES CAN START FIRES,EVEN AFTER SEVERAL DAYS OF INACTIVITY.NEVER DISPOSE OF
ASHES IN ACOMBUSTIBLE CONTAINER.REMOVE ASHES ONLY.WHEN STOVE AND ASHES ARE COLD
Whenever the ashes get 3 – 4” (76 – 102 mm) deep in the firebox, they should be emptied into the
Ash Drawer, using the following instructions:
1. Make sure the fire is out, and the stove is cold.
2. Lift the ash dump plug at the left rear of the firebox by hooking the poker through the loop
on the cover and lifting up. Figure 3.1 Ash removal
3. Push the ashes through the hole and leave some ashes to cover the ash dump plug once it is
replaced. Leave an ash bed of approximately 1”deep on the firebox bottom to help maintain a
hot ember bed.

19
4. Clear the ashes from the area where the plug normally sits so that it will properly seat against
the opening edges; tap it down with your poker to ensure proper seating.
5. Cover the plug with the remaining ashes and continue operation of your stove as usual. The
Ash Drawer is shown in Figure 3.1 and can be removed by pulling it out toward you. Lift the
Ash Drawer slightly or the pedestal base may get scratched. Close the rear half of the Ash
Drawer lid to prevent spillage. Ashes should be placed in a metal container with a tightly
fitting lid. This closed container should be placed on a non-combustible floor or on the ground,
well away from all combustible materials, pending final disposal. Ensure the rear half of the lid
is open before replacing the Ash Drawer.
If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained
in the closed container until all cinders have thoroughly cooled. Do not place other waste materials
in the metal ash container. If bright embers are glowing above the ash dump port during a low or
medium low fire, air may be leaking past the ash plug. If this is happening, a possible over fire
hazard exists. The stove should be shut down and allowed to cool. Properly seal the ash dump
plug to the stove.
3.3 Chimney Cleaning
Regular chimney maintenance, as well as good burning practices, are required to prevent chimney
fires. The chimney and the chimney connector pipe must be maintained in good condition and be
kept clean in order to be safe. This means that the chimney should be checked regularly for
creosote build-up. Inspection and cleaning of the chimney is facilitated by a removable baffle.
CAUTION:OPERATION OF YOUR OSBURN 1800 WITHOUT THE BAFFLE MAY CAUSE UNSAFE AND
HAZARDOUS TEMPERATURE CONDITIONS AND WILL VOID THE WARRANTY.
Contact your local, municipal, state, or provincial fire authority for information on how to handle a
chimney fire before there is any chance that it may happen.
When wood (especially green wood) is burned without adequate heat or air supply, it produces
tar and other organic vapours (smoke), which combine with expelled moisture to form creosote.
The creosote vapours 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 which could be hazardous. Check frequently for creosote build-up. In the event
of a stove or chimney component failure, replace only with equipment that is equivalent to the
original, available from your Osburn dealer.
