Masonry Chimney & Fireplace
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. To ensure that a masonry
chimney meets the minimum standards of the National Fire Protection Association (NFPA) it
should be inspected by a professional to make sure there are no cracks, loose mortar or
other signs of deterioration and blockage. Also have the chimney cleaned before the stove is
installed and operated.
When connecting the stove through a combustible wall to a masonry chimney, special methods
are needed. Refer to figure 7. 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”
(150mm)
flue, it should be relined with a suitably listed 6”
(150mm) stainless
steel liner. Do not downsize the
flue to less than 6” unless the venting system
is straight and
exceeds 25ft (7.6mt) in height. When passing through a combustible wall, the use of an insulated
listed thimble is required.
There are listed kits available to connect a stove to a masonry fireplace. The kit is an adapter
that is installed at the location of the fireplace damper. The existing damper may have to be
removed to allow installation.
