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.

CLEARANCES FROM COMBUSTIBLES
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. It is of outmost importance that the clearances
to combustible materials be scrupulously respected upon installation of the stove you have
selected. Refer to the tables below :
A- REAR B- SIDE C - CORNER
24” 26” 26”
You may decrease these 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. The
installation standards of such heat radiation shields are listed on the following page.
IT IS STRICTLY FORBIDDEN TO PLACE WOOD WITHIN MINIMUM CLEARANCES
REDUCED CLEARANCES
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).

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.

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.

CHIMNEY
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 UL 103 standards; therefore it must be a
Type HT (2100°F). It is extremely important that it be installed according to the
manufacturer's specifications.
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the National Building Code. It must be lined with fire clay bricks, metal or
clay tiles sealed together with fire cement. (Round flues are the most efficient).
The interior diameter of the chimney flues must be identical to the stove's smoke exhaust.
(6”). A flue which is too small may cause draught problems, while a large flue favours
rapid cooling of the gas, and hence the build-up of creosote and the risk of chimney fires.
Note that it is the chimney and not the stove which creates the draught effect; your stove's
performance is directly dependent on an adequate draught from your chimney.
The following recommendations may be useful for the installation of your chimney:
1. Do not connect this unit to a chimney flue serving another appliance.
2. It must rise above the roof at least 3' (0.9 mm) from the uppermost point of
contact.
3. The chimney must exceed any part of the building or other obstruction within a
10' (3.04 m) distance by a height of 2' (0.6 m).
4. Installation of an interior chimney is always preferable to an exterior chimney.
Indeed, the interior chimney will, by definition, be hotter than an exterior
chimney, being heated up by the ambient air in the house. Therefore the gas
which circulates will cool more slowly, thus reducing the build-up of creosote
and the risk of chimney fires.
5. The draught caused by the tendency for hot air to rise will be increased with an
interior chimney.
6. 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 draught, and it should
be cleaned when necessary.
7. Clean your chimney every 2 months.

13
CHIMNEY CONNECTOR (STOVE PIPE)
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.
•Installation of a "barometric draft stabiliser" (fireplace register) on a connector is not
recommended.
•Furthermore, installation of a draft damper is prohibited. 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.

WOODSTOVE UTILISATION
Your heating unit was designed to burn wood only; no other materials should be burnt.
Wastes and other flammable materials should not be burnt in your wood stove. Any type
of wood may be used in your stove, but specific varieties have better energy yields than
others. Please consult the following table in order to make the best possible choice.

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 humidity content (in
weight) is reduced below 20% of the weight of the log. It is very important to keep in mind
that even if the wood has been cut since one, two or even more years, it is not necessarily
dry, if it has been stored in poor conditions; under extreme conditions, it may even rot
instead of drying. The vast majority of the problems related to the operation of a wood
stove are caused by the fact that the wood used was too damp or had dried in poor
conditions. These problems can be:
•ignition problems
•creosote build-up causing chimney fires
•low energy yield
•blackened windows
•incomplete log combustion

20
Smaller pieces of wood will dry faster. All logs exceeding 6" in diameter should be split.
The wood should not be stored directly on the ground. Air should circulate through the
cord. A 24" to 48" air space 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
When the stove is thoroughly warmed, place one piece of split wood (about five inches in
diameter) parallel to the door on the bed of red embers.
Close the door. If ignition of the piece is accomplished within 90 seconds from the time if
was placed in the stove, your wood is correctly dried. 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 or freshly cut. Do not use this wood in your stove. Large amounts of creosote
could be deposited in your chimney, creating potential conditions for a chimney fire.
THE FIRST FIRES
The fresh paint on your stove needs to be cured to preserve it's quality. Once the fuel
charge is properly ignited, only burn small fires in your stove for the first four hours of
operation.
Make sure that there’s 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.
IGNITION
Place several rumpled sheets of paper in the centre of the combustion 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.
Before igniting the paper and kindling wood, it is recommended that you warm up the
chimney. This is done in order to avoid back draft 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
chimney. Once the updraft movement is initiated, you are ready to ignite the stove by
lighting the paper and kindling wood inside the combustion chamber.
We therefore advise you to leave the door slightly opened (1/4") for a 10 to 30 minutes
period, under supervision, in order to allow for good combustion. After this time, you
must close the door.
