The heat vent grating (Picture 15 pos. 6) has to be installed on the upper part of the hood at about 20 cm from the
roof. This must always be installed since its function is that of letting the heat collected within the hood
(overpressure) flow out into the room.
7.1. EXTERNAL AIR INTAKE
For a good operation of the device, it is MANDATORY that a sufficient
quantity of air for the combustion and the re-oxygenation of the room is
introduced the installation room itself. This means that, through proper
openings communicating with outside, the air for combustion must
circulate also with closed doors and windows.
•
The air intake must be positioned so that it cannot be
obstructed.
•
Be communicating with the installation room of the device
and be protected by grating.
•
Should the air inflow be obtained by means of openings
communicating with the outside of the adjacent rooms, it is
necessary to avoid air intakes in connection with garages,
kitchens, bath-rooms, thermal units.

* (For a better comfort and corresponding oxygenation of environment, the
combustion air can be directly withdrawn at the outside through a junction (B1)
which is to be connected with a flexible pipe (not furnished)for the external air
intake. The connection pipe must be flat with a minimum diameter of 100 mm,
a maximum length of 4 m and with no more than 3 bends. If there is a direct connection with the outside it must be endowed with a
special windbreak).
8. CONNECTION AND MAINTENANCE OF VENTILATION
The control unit and the plant must be installed and connected by authorized personnel according to the
standards in force. (see CHAP. 1)
ATTENTION: the feeding cable must not be in contact with hot parts.
