8.2.2 MASONRY FLUE SYSTEMS
The wood fire may also be connected
to a masonry flue system, provided
the flue system complies with AS/NZS
2918 or with the construction rules
found in the building code enforced
locally. The flue system must have
either a clay liner or a suitably listed
stainless steel liner. If the masonry
flue
system
has
a
square
or
rectangular liner that is larger in cross
sectional area than a round 150 mm
(6") flue, it should be relined with a
suitably listed 150 mm (6") stainless
steel liner. Do not downsize the flue to
less than 150 mm (6") unless the flue
system is straight and exceeds 8 m (25
feet) in height. When passing through
a combustible wall, the use of an
insulated listed thimble is required.
