CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same diameter as the stove outlet (6”). If this
is not the case, we recommend you contact your dealer in order to insure there will be no problem
with the draft.
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 (crimped end) 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. Any installation with a horizontal
run of chimney pipe must conform to NFPA 211. You may contact NFPA (National Fire Protection
Association) and request the latest edition of the NFPA Standard 211 .
To insure a good draft, the total length of the coupling pipe should never exceed 8’ to 10’ (2.4m
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 elbows in the smoke exhaust system.
Installation of a “barometric draft stabilizer” (fireplace register) on a smoke exhaust system is
prohibited.
Furthermore, installation of a draft damper is not recommended. Indeed, with a controlled combustion
wood stove, the draft is regulated upon intake of the combustion air in the stove and not at the exhaust.
