Installation
Compliance with standards
This cooktop must be installed by a licensed gasfitter in accordance with the requirements of local gas and electrical authorities, as well as the latest 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 combustion products evacuation device. It must be installed and connected in accordance with current installation regulations. particular attention should be 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.AUS 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 10m3, it will require an air vent of 50cm2 effective area unless it has a door which opens directly to outside. If the room has a volume of less than 5m3, it will require an air vent of 100cm2 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.
