3.6. COMBUSTION AIR AND AIR FILTER
The PowerSystem is equipped with a combustion air intake that
allows the intake of air that is essential to combustion. This
intake is located on the rear of the unit. It is equipped with a
pollen filter that can be easily cleaned. It is advisable to draw
combustion air from inside the room of installation and not from
outdoors. This will prevent intake of impurities, dust or
humidity.
The air filter is cylindrical. It is located just back of the unit at
the start of the tube. It is composed of a fine metallic mesh.
The filter must be regularly services. To reach it, the combustion
chamber must be extracted on its slides. To do this, refer to the
chapter on maintenance.
3.7. HOOD VENTILATION NOZZLES
3.7.1. Introduction
The Powerbox can be used in two different ways:
• As an insertion in an existing cladding
• As a new installation
If the Powerbox is inserted in an existing cladding the ventilation grilles
on the cladding will be used.
If the Powerbox is used as a new installation, MCZ recommends
installing the ventilation nozzles as described in paragraph 3.9.2
3.7.2. Hood ventilation nozzles for new cladding.
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.
Because of the high power of the PowerBox, the structure reaches high
temperatures. Therefore, continuous and efficient ventilation must
always be ensured inside the cladding.
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.
