The monoblock can distribute heated air by natural convection or forced convection by means of a
centrifugal fan; therefore, during installation, it is necessary to establish the type of ventilation or
convection to be adopted:
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 Figure 12)
By choosing this convection system, it is recommended not
to install the electrical fan. (see Chap.21)
B) FORCED CONVECTION:
By installing a centrifugal fan, 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.
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.
b) Fasten the pipes by means of clamps to the related
collars and openings, after having removed the semi-
blanks caps.
c) Each pipe must not exceed 2 m of length for natural
ventilation and 4 m for forced ventilation, and has
to be insulated with insulating materials to avoid noise
