5.6.
AIR USED FOR COMBUSTION
The cooker, during operation, takes air through the
opening located on the rear right side of the cooker from the
room in which it is located.
The outside air supply point can be connected to the wall
opening through a pipe of 80 mm diameter with a gasket.
One grate for constant ventilation must be placed on the
outside; In very windy areas exposed to rain and wind,
adequate protection must be foreseen.
Ensure that the air intake opening is positioned so it
cannot be accidentally blocked.
In the event that it is impossible to achieve external air
intake through the wall behind the cooker (the wall is not
outer), an opening must be made on one of the outer walls of
the room in which the cooker is located.
If it is impossible to supply external air into the room, it is
possible to make an outer opening in the adjacent room, but
continuous communication through the transit grid must be
enabled. The cooker configured in this way is no longer
sealed from the space in which it is installed.
It is forbidden to take air from the garage, a warehouse
with a flammable material or from a place with a fire hazard.
If there are other heaters in the room and the cooker is
not sealed from the space in which it is installed, the air
intake opening must guarantee the amount of air necessary
for the operation of all the devices in the room.
If one or more fans for the extraction of air (aspirators)
are used in the room where the cooker is fitted, it is
necessary to ensure that poor operation of the cooker
caused by the insufficient air required for combustion does
not occur.
