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.

When a metal prefabricated chimney is used, the
manufacturer’s installation instructions must be
followed. You must also purchase (from the same
manufacturer) and install the ceiling support package
or wall pass-through and “T” section package, firestops
(where needed), insulation shield, roof flashing, chimney
cap, etc. Maintain proper clearance to the structure
as recommended by the manufacturer. The chimney
must be the required height above the roof or other
obstructions for safety and proper draft operation.
