CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same diameter as the stove outlet. If
this is not the case, we recommend you contact your dealer in order to insure there will be
no problem with the draught.
The stove pipe must be made of aluminized or cold roll steel with a minimum thickness of
0.021" or 0.53 mm. It is strictly forbidden to use galvanized steel.
Your smoke pipe should be assembled in such a way that the male section of the pipe faces
down. Attach each of the sections to one another with three equidistant metal screws.
The pipe must be short and straight. All sections installed horizontally must slope at least
1/4 inch per foot, with the upper end of the section toward the chimney.
To insure a good draught, the total length of the coupling pipe should never exceed 8' to 10'
(24 to 3.04 m). (Except for cases of vertical installation, cathedral-roof style where the
smoke exhaust system can be much longer and connected without problem to the chimney
at the ceiling of the room).
There should never be more than two 90 degrees elbow in the smoke exhaust system.
Installation of a "barometric draught stabiliser" (fireplace register) on a smoke exhaust
system is prohibited.
Furthermore, installation of a draught damper is not recommended. Indeed, with a controlled
combustion wood stove, the draught is regulated upon intake of the combustion air in the
stove and not at the exhaust.
