Chimney

Your woodstove may be hooked up with a prefabricated or masonry chimney. If you are

using a prefab chimney, it must comply with ULC S629 standards; therefore it must be of

the 2100 °F / 650 °C. (2" / 51 mm thick insulated type). It is extremely important to install

the chimney 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 firebricks, metal or clay

tiles sealed together with fire cement. (Round flues are the most efficient).

The interior diameter of the chimney flues must be identical to that of the stove smoke

exhaust. A flue which is too small may cause draught problems, while a large flue favors

rapid cooling of the gas, and hence the build-up or creosote and the risk of chimney fires.

Current practice requires that the diameter of the chimney flue does not exceed the stove

exhaust one by more than 30-35%. Note that it is the chimney and not the stove that

creates the draught effect. Your stove's performance is directly dependent on an

adequate draught from your chimney.

The following recommendations may be useful for the installation of your chimney:

1) It must rise above the roof at least 3' (0,9 m) from the uppermost point of contact.

2) The chimney must exceed any part of the building or other obstruction within a 10'

(3,04 m) distance by a height of 2' (0,60 m).

3) 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 gases which circulate will cool more

slowly thus reducing the build-up of creosote and the risk of chimney fires.

4) The draught causes by the tendency for hot air to rise will be better with an interior

chimney.

5) You must not install more than one heating unit per chimney flue.

6) Use of a fire screen at the extremity of the chimney requires regular inspection in

order to insure that it is not obstructed thus blocking the draught, and it should be

cleaned when necessary.
