CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same
diameter as the stove outlet (6”). If this is not the case, we
recommend you contact your dealer in order to ensure 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 (crimped end) 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. Any installation with a
horizontal run of chimney pipe must conform to NFPA 211. You
may contact NFPA (National Fire Protection Association) and request the latest edition of the NFPA Standard
211. To ensure a good draft, the total length of the coupling pipe should never exceed 8’ to 10’ (2.4m 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° elbows in the smoke exhaust system. Installation of a “barometric draft stabilizer” (fireplace register) on
a smoke exhaust system is prohibited. Furthermore, installation of a draft damper is not recommended. 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.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too
much draft may cause excessive temperatures in the appliance. Inadequate draft may cause backpuffing into
the room and ‘plugging’ of the chimney. Inadequate draft will cause the appliance to leak smoke into the room
through appliance and chimney connector joints. An uncontrollable burn or excessive temperature indicates
excessive draft.

CHIMNEY
Take into account the chimney’s location to ensure
it is not too close to neighbors or in a valley which
may cause unhealthy or nuisance conditions. Your
wood stove may be hooked up with a 6” factory
built or masonry chimney. If you are using a factory
built chimney, it must comply with UL 103 or CSA-B365
standard; 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. Note: 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’ (0.9m) 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’ (0.6m).
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 ensure that it is not
obstructed thus blocking the draft, and it should be cleaned when used regularly.
