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 2 .
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.
There must be a distance of at least 650
mm between the hob of the cooker and
any wall cupboard or extractor hood posi-
tioned immediately above (see fig. 7.4).
DISCHARGING PRODUCTS OF
COMBUSTION
Extractor hoods connected directly to
the outside must be provided, to allow
the products of combustion of the gas
appliance to be discharged (fig. 7.4).
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. 7.5).
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”.
This appliance is not connected to a
device to evacuate the combustion
products. This must be installed and
connected in conformity with the
installation rules in force. Pay special
care to room ventilation as well.
