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.
