Figure No.5 - Exterior diagram of the casing
In order to enable suitable air
circulation and correct operation, the
casing must have a fresh-air inlet with a
minimum section of 1,000cm
2
beneath the
level of the actual appliance and a hot-air
outlet measuring at least 1,000cm
2
above it
(just before the insulating deflector inside
the casing). These inlet and outlet sections
must ensure air renewal in such a way as to
avoid damage to parts inside the hood due
to excess temperature.
This specification must be observed
regardless of the type of installation
chosen (with or without forced ventilation,
combustion air from indoors or outdoors,
directed hot-air outlets with or without
pipes, etc.). A further hot-air ventilation
grille is also recommended between the
insulating deflector on the hood and the
ceiling.
¡Warning! : on appliances on which it is
possible to pipe air to the firebox, the hood
requires a further air inlet at the bottom, in
addition to the 1,000cm
2
inlet, if the air
supply comes from the room in which the
appliance is fitted.
