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.
