CHIMNEY
Take into account the chimney’s location to insure it is not too close to neighbours 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. (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 insure that it is
not obstructed thus blocking the draft, and it should be cleaned when used regularly.
