In this way, the following targets are achieved:
•
a greater safety
•
an increase of the heat created by air circulation around the device.
The heat vent grating (Figura 16 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

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.
