POSITIONING THE STOVE
Itis veryimportant toposition thewood stoveas closeas possibleto thechimney, andinan areathat
willfavor themost efficientheatdistribution possiblethroughout thehouse. Thestove musttherefore
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. 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 fail to respect required clearances.

FLOOR PROTECTOR
Your wood stove should be placed on a non-combustible surface with a R value of 1.0. For multiple
layers, add R-values of each layer to determine the overall R-value. The floor protector should be
under the stove, eighteen inches beyond the front and eight inches beyond each side of the fuel
loading and ash removal opening. If there is a horizontal section of chimney connector, the floor
protector should go under it and two inches beyond each side
Convert specification to R-value:
k-factor is given with a required thickness (T) in inches: R=1/k x T
C-factor is given: R=1/C
Example:
If the floor protector is 4" brick with a C-factor of 1.25 over 1/8" mineral board with a “k” factor
of 0.29 the total R-value of the system is:
4" brick C=1.25, R=1/1.25=0.8
1/8" mineral board K=0.29, R=1/0.29 x 0.125=0.431
Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231
Total R is greater than 1.0, the system is acceptable.
The floor protector should exceed the stove as follows:

CLEARANCES TO COMBUSTIBLES
It is of utmost importance that the clearances to combustible materials be strictly adhered to during
installation of the stove. Refer to the tables below :
Floor to ceiling height must be at least 7’ (84”) in all cases.
The clearance between the flue pipe and a wall are valid only for verticle walls and for verticle flue
pipe.
The flue pipe must not go through roof trussing, an attic, a closet, a floor, a combustible partition,
or similar spaces.
A flue pipe crossing a combustible wall must have a minimum clearance of 18”.
To reduce flue clearances from combustible materials, contact your local safety department.

REDUCED CLEARANCES (CANADA ONLY)
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. 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.

CHIMNEY
Yourwood stovemay behookedup withafactory builtor masonrychimney.If youare usingafactory
built chimney, it must comply with UL 103 or ULC S629 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 specifica-
tions 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 flue must be identical to the stove smoke exhaust. A flue which
is too small may cause draft 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 draft effect; your stove's performance is directly dependent on an adequate draft
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' (3.04m)
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 draft 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 draft, and it should be cleaned when
regularly.

CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same diameter as the stove outlet. If this is not
the case, we recommend you contact your dealer in order to insure there will be no problem with the
draft.
The stove pipe must be made of aluminized or cold roll steel with a minimum thickness of 0.021" or
0.53 mm. It is strictly forbidden to use galvanized steel.
Your smoke pipe should be assembled in such a way that the male section of the pipe faces down.
Attach each of the sections to one another with three equidistant metal screws.
The pipe must be short and straight. All sections installed horizontally must slope at least 1/4 inch
per foot, with the upper end of the section toward the chimney.
To insure a good draft, the total length of the coupling pipe should never exceed 8' to 10' (24 to 3.04
m). (Except for cases of vertical installation, cathedral-roof style where the smoke exhaust system
can be much longer and connected without problem to the chimney at the ceiling of the room).
There should never be more than two 90 degrees elbows in the smoke exhaust system.
Installationofa“barometricdraft stabilizer”(fireplaceregister) onasmoke exhaustsystemis prohibited.
Furthermore,installation ofadraft damperisnot recommended.Indeed,with acontrolledcombustion
wood stove, the draft is regulated upon intake of the combustion air in the stove and not at the
exhaust.
