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 flue, it should be relined
with a suitably listed 150 mm stainless steel
liner. Do not downsize the flue to less than
150 mm unless the flue system is straight
and exceeds 8 m in height. When passing
through a combustible wall, the use of an
insulated listed thimble is required.
