Installation
When connecting the oven 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" (152 mm) flue, it should be
relined with a suitably listed
6" (152 mm) stainless steel liner.
Do not downsize the flue to less
than 6" (152 mm) unless the venting
system is straight and exceeds
25ft (7.6 m) in height. When passing
through a combustible wall, the
use of an insulated listed thimble is
required.
There are listed kits available to
connect an oven 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.

where it passes through the roof and
at least 2' (610 mm) higher than the
highest part of the roof or structure
that is within 10' (3050 mm) of the
chimney, measured horizontally.
