2.3 CHIMNEY CONNECTOR
Your chimney connector (commonly called stove pipe) and chimney must have the same
diameter as the stove’s exhaust outlet. The stove pipe must be made of aluminized or
cold roll steel with a minimum 24-gauge thickness (0.021" or 0.53 mm). It is strictly
forbidden to use galvanized steel.
The following recommendations may be useful for the installation of your chimney
connector:
Your chimney connector should be assembled in such a way that the male end
(crimped) faces down to prevent creosote dripping outside the joints. Attach each
of the sections to one another with three equidistant metal screws. Also use
three equidistant metal screws to attach the connector to the stove’s exhaust
collar. See Figure 2.3 (A) and Figure 2.3 (B).
The pipe must be short and straight. All sections installed horizontally must
slope at least ¼ inch per foot, with the upper end of the section toward the
chimney. See Figure 2.3 Detail B.
To insure a good draft, the total horizontal length of the connector should never
exceed 8' to 10' (2.4 to 3.04 m). In the case of vertical installation, the total
length of the connector can be much longer and connected without problem to
the chimney at the ceiling level.
There should never be more than two 90 degrees elbows in the whole connector
and chimney system. Never start with a 90
o
elbow. Always go up vertically for at
least 2 feet from the flue spigot before using a 90
o
elbow.
The connector must not pass through any combustible material, nor may it pass
through a concealed space (such as an attic, roof space, or closet). If passing
through a wall, ceiling, or into a masonry chimney, use either chimney
components listed for that specific use, or means acceptable to local authorities
having jurisdiction over the installation.
Installation of a "barometric draft stabiliser" (fireplace register) on a connector is
not recommended.
