CHIMNEY
Your wood stove may be hooked up with a factory built or masonry chimney, matching the diameter of the stove exhaust. 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 cement. (Round fl ues are the most effi cient).
The 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 favors 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 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:
• It must rise above the roof at least 3' (0.9m) from the uppermost point of contact.
• The exterior portion should be double or triple wall pipe to ensure proper draft.
• 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).
• Installation of an interior chimney is always preferable to an exterior chimney. The interior chimney will be hotter than an
exterior chimney that is being cooled by the ambient air outside the house. Therefore the gas which circulates will cool slower,
thus reducing the build-up of creosote and the risk of chimney fi res.
• The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
• 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.
