6.3.2 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 or 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.
6.4 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 3 ft. (1 m) above
the highest point of contact with the
roof, and at least 2 ft. (60 cm) higher
than any roof line or obstacle within
a horizontal distance of 10 ft. (3
m).
6.5 Chimney Location
Because the venting system is the engine that drives the wood heating system, it must have the
right characteristics. The signs of bad system design are cold back drafting when there is no fire
in the stove, slow kindling of new fires, and smoke roll-out when the door is opened for loading.
There are two guidelines to follow. First, the chimney should be installed up through the heated
space of the house, not out and up an outside wall. Second, the chimney should penetrate to
the top of the building at or near the highest heated space.
Venting systems that rise straight up from the stove flue collar provide the best performance.
Chimneys that rise inside the warm space of the house tend to provide a small amount of draft
even when there is no fire burning. This means that when a fire is lit, the smoke goes up the
