8.2.2 Masonry Chimneys
The stove may also be connected to a
masonry
chimney,
provided
the
chimney complies with the construction
rules found in the building code
enforced locally. The chimney must
have either a clay liner or a suitably
listed stainless steel liner. If the
masonry chimney has a square
rectangular liner that is larger in cross
sectional area than a round 6” flue, it
should be relined with a suitably listed
6” stainless steel liner. Do not
downsize the flue to less than 6” unless
the venting system is straight and
exceeds 25 feet in height. When
passing through a combustible wall, the
use of an insulated listed thimble is
required.
8.3
Minimum Chimney Height
The top of the chimney should be tall
enough to be above the air turbulence
caused when wind blows against the
house and its roof. The chimney must
extend at least 1 m (3 ft.) above the
highest point of contact with the roof,
and at least 60 cm (2 ft.) higher than
any roof line or obstacle within a
horizontal distance of 3 m (10 ft.).
