published versions of the following standards:
" AS/NZS 5601 Gas Installation code
" SAA Wiring Rules.
Prior to installation, ensure that the local distribution
conditions (nature of the gas and gas pressure) and
the adjustment conditions are compatible. The
adjustment conditions for this appliance are stated
on the data badge which is fitted on the back panel.
This appliance is not designed to be connected to a

given to the relevant requirements regarding
ventilation.
LOCATION
Where the total input of all appliances exceeds 3
MJ/h for each cubic metre of the room or enclosure
volume, the space shall be ventilated by one of the
methods detailed below. For the purpose of
assessing the adequacy of ventilation, the space
that cannot be isolated by doors is the 'volume of a
room'.
Natural ventilation direct from outside
Two permanent openings shall be provided directly
to outside. The openings shall be located to ensure
the distance between the top of the upper opening
and the ceiling of the room or enclosure, and the
distance between the bottom of the lower opening
and the floor of the room or enclosure does not
exceed 5% of the height of the room or enclosure.
The minimum free ventilation area provided by each
opening shall be calculated using the following
formula:
A = 3 × T
where
A = the minimum free ventilation area (cm2)
T = the total gas consumption of all appliances
(MJ/h)
The minimum vertical dimension of any free
ventilation opening shall be 6 mm.
NOTE 1 When used in this Clause, the term 'directly
to outside' means any one of the following options,
provided that the ventilation path is unobstructed by
building material or insulation:
(a) Directly through an outside wall (preferred
option).
(b) Through to an outside wall but offset.
(c) Into a cavity ventilated to outside.

(d) Into an underfloor space ventilated to outside.
(e) Into a roof space ventilated to outside.
NOTE 2 The two openings may be combined
provided that the top and bottom of the opening
reach the limits set by this Clause.
Natural ventilation via adjacent room
Two permanent openings shall be provided in the
room or enclosure. The openings shall be located to
ensure the distance between the top of the upper
opening and the ceiling of the room or enclosure,
and the distance between the bottom of the lower
opening and the floor of the room or enclosure does
not exceed 5% of the height of the room or
enclosure.
The minimum free ventilation area provided by each
opening shall be calculated using the following
formula:
A = 6 × T
where
A = the minimum free ventilation area (cm2)
T = the total gas consumption of all appliances
(MJ/h)
These requirements shall apply to all subsequent
rooms until a room is ventilated to outside, in
accordance with the previous section, or the total
input of the appliances does not exceed 3 MJ/h for
each cubic metre of the total volume of the
enclosure and rooms.
The minimum vertical dimension of any free
ventilation opening shall be 6 mm.
NOTE: The two openings may be combined
provided that the top and bottom of the opening
reach the limits set by this Clause.
PROVISION FOR VENTILATION
The room containing the cooker should have an air
supply in accordance with BS 5440: Part 2.
The room must have an opening window or
equivalent; some rooms may also require a
permanent vent. If the room has a volume between 5
and 10m
3
, it will require an air vent of 50cm
2
effective area unless it has a door which opens
directly to outside. If the room has a volume of less
than 5m
3
, it will require an air vent of 100cm
2
effective area. If there are other fuel burning
appliances in the same room, BS 5440: Part 2
should be consulted to determine air vent
requirements.
