POSITIONING THE STOVE
Itis very important to position the wood stove as close as possible to the chimney, and in an area
that will favour the most efficient heatdistributionpossiblethroughout the house. The stove must
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
awoodstove. A wood stove also functionsbyconvection,thatisthrough the displacementofhot
air accelerated upwards and its replacement with cooler air. If necessary, the hot air distribution
from the stove may be facilitated by the installation of a blower.
The wood stove must not be hooked up to a hot air distribution system since an
excessive accumulation of heat may occur.
A wood stove must never be installed in a hallway or near a staircase, since it may block
the way in case of fire or fall to respect required clearances.
FLOOR PROTECTOR
Your wood stove should be placed on a non-combustible surface. Install a floor protection using
a 6mm thick fibre cement sheet with thermal conducticity of 0.41W/m degree K underneath the
heater.
The floor protector should project beyond the stove as follows:
Minimum Distance From the Door Opening
FRONT
300 mm
SIDES
200 mm
BACK
N/A

8
CLEARANCES TO HEAT-SENSITIVE MATERIALS
It is of outmost importance that the clearances to heat-sensitive materials be carefully
maintained upon installation of the stove you have selected. Refer to the table below :
CLEARANCES TO HEAT SENSITIVE MATERIALS
Model A B C D E
OSBURN 1800 125mm 450mm 75mm 300mm 200mm
Floor to ceiling height must be at least 1,500 mm in all cases.
The clearance between the flue pipe and a wall are valid only for vertical walls and for
vertical flue pipe.
Where the flue passes through walls, ceilings or roofs, ventilated double flue-pipe casings
must be used around the flue pipe, along with ceiling plates as specified in
AS/NZS2918:2001

9
REDUCED CLEARANCES USING SHIELDING
You may decrease the minimum clearances to heat-sensitive materials by installing heat
radiation shields between the walls or the ceiling and the stove. These heat radiation shields
must be installed permanently, and must be made of a heat-resistant or heat-tolerant material.
An air gap must separatethe heat shield from any heat-sensitivesurface. Furthermore,theheat
shield shall extend inall directions beyond the boundariesoftheappliance surface by a distance
of not less than 450 mm. Exceptions may apply. Refer to AS/NZS2918:2001.
Followingtheinstallationofsuchheatradiationshields,theminimum clearancestoheat-sensitive
materials may be reduced by applying the clearances factor in the table below:

NOTES :
1- Masonry may be used as a heat shield material.
2- Where heat shields are used to reduce appliance clearance dimensions, additional flue
shielding may also be required. Refer to AS/NZS2918:2001.
3- Non standard installations – Refer to AS/NZS2918 for guidance.

THIS STOVE IS NOT DESIGNED TO BE USED WITH THE DOOR OPEN.THE DOOR MAY BE OPEN ONLY
DURING LIGHTING PROCEDURES.NEVER LEAVE THE STOVE UNATTENDED WHEN THE DOOR IS OPEN.
HOT WHILE IN OPERATION,KEEP CHILDREN,CLOTHING AND FURNITURE AWAY.CONTACT MAY CAUSE
SKIN BURNS.WEAR GLOVES TO OPERATE YOUR STOVE.
CAUTION
THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL TIMES IN ACCORDANCE WITH THESE
INSTRUCTIONS.
THE USE OF SOME TYPES OF PRESERVATIVE-TREATED WOOD AS A FUEL CAN BE HAZARDOUS.
Your stove was designedto burn wood only; no other materialshould be burnt. Waste and other
flammable materials should not be burnt in your wood stove.
IT IS EXTREMELY IMPORTANT THAT YOU USE DRY WOOD ONLY IN YOUR WOOD
STOVE. The wood must have dried for 9 to 15 months, such that the moisture content below
20%. It is very important to keep in mind that even if the wood has been cut one, two or even
more years, it is not necessarily dry.

12
Many problems related to the operation of a wood stove are caused by the fact that the wood
used is too damp or has dried in poor conditions. These problems can be:
problems lighting the fire
creosote build-up causing flue fires
low energy yield
blackened windows
incomplete log combustion
Smaller pieces of wood will dry faster. All logs exceeding 150 mm in diameter should be split.
The wood should not be stored directly on the ground. Air should circulate through the cord. A
half to one metre air gap should be left between each row of logs, which should be placed in the
sunniest location possible. The upper layer of wood should be protected from the element but
not the sides.
TESTING YOUR WOOD
Whenthe stove is thoroughly warmed, place one piece of split wood (about 130 mmindiameter)
parallel to the door on the bed of red embers.
Keep the air control full open by pulling on it and close the door. If ignition of the piece is
accomplishedwithin90seconds fromthetimeifwasplacedinthestove,yourwoodiscorrectlydried.
If ignition takes longer, your wood is damp.
If your wood hisses and water or vapour escapes at the ends of the piece, your wood is soaked
orfreshly cut. Do not use this wood in your stove. Large amounts of creosote couldbedeposited
in your flue system, creating potential conditions for a flue fire.
THE FIRST FIRES
The fresh paint on your stove needs to be cured to preserve its quality. Once the fuel charge is
properly ignited, only burn small fires in your stove for the first four hours of operation. Never
open the air control more than necessary to achieve a medium burn rate.
Make sure that there is enough air circulation while curing the stove. The odours could be
smelled during the 3 or 4 first fires. Never start your stove outside. You will not be able to see if
you are over heating. The smoke resulting from the paint curing process is not toxic.
LIGHTING THE FIRE
After making sure that the stove air intake controls are fully open to the right (locatedon the front
of the stove, see Figure 6), placeseveral rumpled sheets ofpaper inthecenterofthecombustion
chamber. Place 8 to 10 pieces of small dry kindling wood over the paper in the form of a tent.
You may also place a few pieces of heating wood, but choose the smaller ones. No chemical
product should be used to light the fire.

13
Before igniting the paper and kindling wood, it is recommended that you warm up the flue. This
is done in order to avoid back draught problems often due to negative pressure in the house. If
such is the case, open a window slightly near the stove and twist together a few sheets of
newspaper into a torch. Light up this paper torch and hold it as close as possible to the mouth of
the pipe inside the combustion chamber to warm up the flue. Once the updraught movement is
initiated, you are ready to ignite the stove by lighting the paper and kindling wood inside the
combustion chamber.
We therefore suggest that you to leave the door slightly opened (20 mm) for a few minutes,
under supervision, in order to allow for good combustion. After this time, you must close the
door and progressively adjust the air control to obtain the desired temperature.
Use Table 1 to adjust the air control to the desired burn rate:
Burn Rate Air control setting
Low Move Control against the L.H. side.
Medium Low Move Control right by 15-20mm from closed position.
Medium High Move Control right by 20-45mm from closed position
High Move Control against the R.H. side
Table 1: Air control settings
Closing the air control down too soon will lower combustion efficiency, and may result in creosote
build-up in the flue system (which could lead to a future chimney fire).
CAUTION:THE ADJUSTMENT RANGE SHOULD NOT BE ALTERED FOR INCREASED FIRING FOR ANY REASON.

HEATING
Controlled combustion is the most efficient technique for wood heating because it enables you to
select the typeof combustionyouwantforeachgivensituation. Thewoodwillburnslowlyifthewood
stove air intake control is adjusted to reduce the oxygen supply in the combustion chamber to a
minimum. On the other hand, wood will burn quickly if the air control is adjusted to admit a larger
quantityofoxygeninthe combustionchamber. Theairintakecontrolon your stove is verysimple. If
you push it completely to the righ, it is fully open. If you push it fully to the left, the combustion air is
reduced to a minimum.
Your OSBURN stove may burn differently according to the species of wood used, its moisture
content, the size and density of the pieces, the length of the flue, the altitude, and outside
temperature.
WARNINGS
NEVER OVERFIRE YOUR STOVE.IF ANY PART OF THE STOVE STARTS TO GLOW RED,OVER FIRING IS
HAPPENING.READJUST THE AIR INTAKE CONTROL AT A LOWER SETTING.
NEVER LOAD YOUR STOVE UP TO THE STAINLESS BAFFLE.ALWAYS LEAVE 5TO 10 CENTIMETERS TO
ALLOW PROPER COMBUSTION THROUGH SECONDARY AIR OPENINGS (NEVER PUT WOOD ABOVE THE
FIREBRICK LINING ON THE FIREBOX). THIS WILL ALSO PREVENT OVERFIRING OF YOUR STOVE.
THE INSTALLATION OF A LOG CRADLE IS NOT RECOMMENDED IN YOUR OSBURN WOOD STOVE.
SHOULD THERE BE A SOOT OR CREOSOTE FIRE IN YOUR FLUE SYSTEM,CLOSE THE AIR CONTROL
COMPLETELY.IMMEDIATELY CALL THE FIRE DEPARTMENT.

15
RELOADING
Once you have obtained a good bed of embers, you should reload the unit. In order to do so,
open the air control to its maximumforapproximately 15 seconds priortoopeningthestovedoor.
Then, proceed by opening the door very slowly; open it by 20 to 40 mm for 10 to 15 seconds
before opening it completely. This procedure will increase the draught and thus eliminate the
smoke which is stagnant in a state of slow combustion in the stove. Then bring the red embers
to the front of the stove and reload the unit. Depending on the type of wood you burn and the
strength of the draught in your flue, you may have to leave the air control open to its
maximum for more than 15 seconds to avoid smoke spillage before you reload the stove.
It is important to note that wood combustion consumes ambient oxygen in the room .In the case
of negative pressure, it is a good idea to allow fresh air in the room by opening a window slightly.

16
CREOSOTE FORMATION AND NEED FOR REMOVAL
Whenwood is burnt slowly, it produces tar and other organicvapours, which combine with expelled
moisture to form creosote. The creosote vapours condense in the relatively cool flue of a slow-
burning fire. As a result, creosote residue accumulates on the flue system. When ignited, this
creosote makes an extremely hot fire. When burning wood, the flue system should be inspected at
least once every two months during the heating season to determine if a creosote build-up has
occurred.
PREVENTING CREOSOTE BUILD UP
Always burn dry wood. This allows clean burns and higher flue temperatures, therefore less
creosote deposit.
Leave the air control full open for about 10 minutes after reloading the stove to bring it back to
proper operating temperatures. The secondary combustion can only take place if the firebox is hot
enough.
Always check for creosote deposit once every two months and have your flue system cleaned at
least once a year.
ASH DISPOSAL
Ashes should be removed from the stove every few days or when ashes get to 50 to 75mm deep.
Always empty the stove when it is cold, such as in the morning.
Always dispose of ashes in a metal container with a tight fitting lid. Place this container on a non
combustible floor or on the ground, well away from all heat-sensitive materials, pending final
disposal. Ifthe ashes are disposed of by burial in soil or otherwise locallydispersed, they should be
retained in the close container until all cinders have thoroughly cooled.
CAUTIONS:
ASHES COULD CONTAIN HOT EMBERS EVEN AFTER TWO DAYS WITHOUT OPERATING THE STOVE.
THE ASH PAN CAN BECOME VERY HOT.WEAR GLOVES TO PREVENT INJURY.
NEVER BURN THESTOVEWITHTHEASHDUMPCAPREMOVED.THISWOULDRESULT IN OVER FIRING THE
STOVE.DAMAGE TO THE STOVE AND EVEN HOUSE FIRE MAY RESULT.

17
ASH DISPOSAL USING ASH DRAWER
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.
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 25mm deep on the firebox bottom to help
maintain a hot ember bed.
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 7 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.
6. Ifthe ashes are disposed of by burial in soilor otherwise locally dispersed,theyshouldbe
retained in the closed container until all cinders have thoroughly cooled. Do not place other
wastematerials in the metal ash container.If bright embers are glowingabovetheashdumpport
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.
