•
At least 3 feet (0.9 m) higher than the highest
part of the roof opening through which it passes.
•
At least 2 feet (0.6 m) higher than any part of the
roof within 10 feet (3 m) measured horizontally
from the top of the chimney.
The recommended minimum chimney height for top
of stove installation is 16 feet (4.9 m) off the floor or
13 feet 5 3/4 inches (4.1 m) from the top of the
stove. For rear exit connection, the recommended
minimum chimney height is 19 feet (5.8m) off the
floor or 16 feet 5 3/4 inches (5.0m) from the top of
the stove. The recommended maximum chimney
height is 30 feet (9m). The Heritage 8024 requires a
draft between 0.06” and 0.1” water column. Ensure
your chimney is long enough to provide the
minimum draft, and use a damper if your installation
has a required chimney height that provides too
much draft.
