Drolet R.C. WOODSTOVE, Instruction Manual, Page: 9 / 16

Couplings
Once the woodstove is placed in the room in accordance with required clearances,
it must be coupled to the chimney with a smoke exhaust system. Verify the
clearance between your stovepipe and the surrounding combustible surfaces. If
the normal 18-inch (457 mm) clearance required cannot be obtained, you may use
an insulated flue pipe or a thermal protection shield. Read and respect
manufacturer's instructions before installation.
Coupling pipes and chimney
must have the same diameter as
the stove outlet. If this is not the
case, contact your supplier in
order to insure there will be no
problem with the draught. Pipes
should be made of aluminized or
ordinary steel with a minimum 24
gauge thickness.
Your smoke evacuation system (pipes) should be assembled in such a way that
the male section of the pipes faces down. Attach each of the sections to one
another with three equidistant metal screws. The pipes must be short and straight.
All sections installed horizontally must slope at least 1/4 inch per foot, with the
lower section toward the stove.
To insure a good draught, the total length of the coupling pipe should never exceed 10
feet (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 of the ceiling of the room). There should never be more than one 90
°
elbow in
the smoke exhaust system.
Installation of a "barometric draught stabilizer" (fireplace register) on a smoke exhaust
system is prohibited. Furthermore, installation of a draught damper is not recommended.
Indeed, with a controlled combustion woodstove, the draught is regulated upon intake of
the combustion air in the stove and not at the exhaust.
The connecting pipe must not go through ceiling, storage area, floor or any other
combustible partition.
