CHOOSING SUITABLE
SURROUNDINGS
In the room chosen to accommodate the
gas appliance, there must be an ade-
quate natural draft to allow combustion of
the gas.
The natural draft must be produced
directly by one or more vents made in
the external walls and providing a total
opening of at least 100 cm
If the appliance does not have a no-
flame safety device this opening must
have an area of at least 200 cm
The vents must be positioned close to
the floor, preferably on the opposite side
to the combustion discharge outlet and
must be designed in such a way that
they cannot be obstructed either from the
inside or the outside.
When it is not possible to provide the
necessary vents, the draft may be sup-
plied from an adjacent room, ventilated in
the required manner, provided it is not a
bedroom or an area at risk.
In this event, the door of the kitchen must
be opened to allow the draft to enter the
room.
DISCHARGING PRODUCTS OF
COMBUSTION
Extractor hoods connected directly to the
outside must be provided, to allow the
products of combustion of the gas appli-
ance to be discharged (fig. 7.8).
If this is not possible, an electric fan may
be used, attached to the external wall or
the window; the fan should have a
capacity to circulate air at an hourly rate
of 3-5 times the total volume of the
kitchen (fig. 7.9).
The fan can only be installed if the room
has suitable vents to allow air to enter,
as described under the heading
"Choosing suitable surroundings".
