CHIMNEY CONNECTOR (STOVE PIPE)
The 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 to ensure there will be no problem with the
draft. The stovepipe must be made of aluminized or cold roll steel
and have a minimum thickness of 0.021” or 0.53mm. It is strictly
forbidden to use galvanized steel. The smoke pipe should be
assembled to promote the male section (crimped end) of the
pipe to be faced down. Attach each section to 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. 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
3.04m). Except for cases of vertical installation, in a 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. The installation of a “barometric draft stabilizer”
(fireplace register) on a smoke exhaust system is prohibited. Furthermore, the installation of a draft damper is not
recommended. 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 a force that 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. An inadequate draft may cause back-puffing into the
room and ‘plugging’ of the chimney. An 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 an
excessive draft.
CHIMNEY
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
must be installed according to the manufacturer’s
specifications. 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. If you are using a masonry chimney, it
must 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 flue must be identical to the
stove smoke exhaust. A flue which is too small may cause draft problems, while a large flue favors 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. Do not connect this unit to a chimney flue serving another appliance.
The following recommendations may be useful for the installation of your chimney:
1. It must rise above the roof at least 3’ (0.9m) from the uppermost point of contact.
2. 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).
3. The 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.
4. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
5. Using a fire screen at the extremity of the chimney requires regular inspection to ensure that it is not obstructed
thus blocking the draft, and it should be cleaned when used regularly.
