CONDITIONS FOR FLUES
(Refer Fig. E)
1. The FLUE shall extend to:
Not less than 600mm above the highest point on the
roof if within 3.0m of that point.
Not less than 1000mm above the intersection
point with the roof and not lower than any point
of the roof within 3.0m.
In any case the length of the flue shall not be
less than 4.6m from the ash floor protector.
In some situations the Local Council may vary
the above requirements.
2. All parts of the chimney exposed to the outside
air shall be suitably insulated in accordance with
the manufacturers' recommendations.
When loose- fill insulation is used in the
adjacent ceiling space, maintain clearance
between the secondary shield and the loose-fill
insulation by provision of a boundary extending
200mm above the ceiling top surface.
This non-combustible boundary shield shall be
capable of preventing accidental migration of
the loose-fill by any action of wind or by
persons moving in the ceiling space.
