Hood ventilation nozzles.

You must install MCZ ventilation nozzles, or nozzles

that ensure the same operation and the same air

passage cross section (see MCZ accessories).
MCZ non risponde di eventuali danni alla struttura o

alla componentistica elettrica causati dalla mancata

osservanza di questa avvertenza.


For proper operation of room ventilation remember that:

• In the lower part of the cladding, an opening for the entry of

convective air must be provided that is not smaller than 400

cm

2

• In the upper part it is necessary to provide a vent opening (in

addition to the ducted air outlets) of at least 230 cm

2

to release

into the room the residual heat that accumulates inside the

cladding. With the COMFORT AIR kit, however, this outlet is

not necessary, because the heat in the cladding is indirectly

drawn in by the fans.

Besides ensuring perfect product operation, this action makes it

possible to recover part of the heat from the structure, which would be

wasted if it were left inside the cladding.
For better understanding of the number, size and function of the

ventilation nozzles to be installed on the cladding, the following are

some possible installation configurations with the relative nozzles.

1a) Grille for convection air outlet
1b) Grille for intake of convection air

Grilles 1a and 1b are essential for releasing the heat that

builds up in the hood. They must be installed, regardless of

the type of installation or cladding to be realized.
