Nectre Fireplaces Baker’s Oven Installation & Operating Instructions Manual page 3

CONSTRUCTING THE FLUE
The Nectre Bakers Oven must be installed with a standard AS2918:2001 Flue Kit with a 900mm
long 180° circumference flue mounted shield.
The flue kit should be made of stainless steel or vitreous enamelled steel and it shall extend
not less than 4.6m above the top of the floor protector and meets the requirements of
AS2918/2001. The length will depend on ceiling height and roof design but the top of the flue
pipe must be a minimum of 600mm above the ridge of the roof if the flue penetrates the roof
within 3m of the ridge. Or to be of sufficient height to be 3m from the roof line horizontally, but
a minimum height of 1m.
If the draft is insufficient or periodic down drafting occurs and the appliance smokes or only
burns slowly, extending the flue or fitting a specialised cowl will usually cure it.
In the roof cavity and above the roof it is essential that the flue has 2 outer casings with a
reasonable air space (at least 25mm) between inner and outer pipes. This double flue is
important to prevent condensation on the upper cooler parts of the flue as well as being a safety
feature. Where the flue penetrates the ceiling and roof, it must comply with AS2918:2001. If the
stove is fitted to an existing chimney, ensure that it is sealed at the base of the chimney with a
register plate and fit the flue pipe up through the plate and continue until it terminates outside
the chimney in accordance with AS2918:2001 4.9.1.
The flue kit must be installed according to the manufacturer's instructions.
