4.9. INSULATING A WOODEN BEAM
The wood beam must be protected with adequate insulation
from heated parts to prevent the risk of fire or damage of the
cladding.
(figure 8)
4.10. INSULATION OF FIREPLACE STOVE
The fireplace stove must also always be separated from nearby
walls and ceilings.
If necessary, use insulating materials to insulate the walls that are in
contact with the unit if they may be damaged or catch fire (walls made
of wood, plasterboard, etc.).
(figure 9)
4.10.1. 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.
