6. VENTILATION HOOD OR ADJACENT LOCAL
The monoblock can distribute heated air by natural convection or
forced convection by means of a centrifugal fan OPTIONAL; therefore,
during installation, it is necessary to establish the type of ventilation
or convection to be adopted. (see CHAP. 19)
A) NATURAL CONVECTION:
To ease the natural circulation of air (upward movement due to the
heating of the same) in the external enclosure of the stack, it is
necessary to remove the underlying semi-blanks. (see Picture 11 –
B-B1) By choosing this convection system, it is recommended not to
install the electrical fan. (see Picture 11 - A)
B) FORCED CONVECTION:
By installing a centrifugal fan (see Picture 11 - A), it is possible to
distribute hot air to adjacent rooms by means of ducts with a length up
to 4 meters. In this case, do not remove the underlying semi-blanks,
remove only one in Picture 11 pos. B1 for a centrifugal fan.
The covering of each monoblock is equipped with 4 outputs with a
diameter of 150 mm for the connection of pipes resistant to heat.
a) Perform the drilling on the walls or on the existing hood to allow the
passage and the application of the (fire-resistant) hoses with a 15 cm
diameter equipped with related openings.
