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). Any nearby obstruction or tree can push air down onto the chimney causing a possible
back draft .
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. Outside chimney pipe should be double or tripple wall to ensure heat is retained in
the chimney to encorporate the correct draft .
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 should be cleaned when used regularly.
