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 is
extremely important that it be installed according to the manufacturer’s specifi cations.
If you are using a masonry chimney, it is important that it be built in compliance with the specifi cations of the
National Building Code. It must be lined with fi re clay bricks, metal or clay tiles sealed together with fi re ce-
ment. (Round fl ues are the most effi
cient).
Th
e interior diameter of the chimney fl ue must be identical to the stove smoke exhaust. A fl ue which is too small
may cause draft problems, while a large fl ue favours rapid cooling of the gas, and hence the build-up of creosote
and the risk of chimney fi res. Note that it is the chimney and not the stove which creates the draft eff ect; your
stove’s performance is directly dependent on an adequate draft from your chimney.
Th
e 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. Th
e 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 defi nition, be hotter than an exterior chimney, being heated up by the ambient air in the house.
Th
erefore the gas which circulates will cool more slowly, thus reducing the build-up of creosote and the risk
of chimney fi res.
5. Th
e draft caused by the tendency for hot air to rise will be increased with an interior chimney.
6. Using a fi re 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.
