VENTILATION HOOD OR ADJACENT LOCAL

The inserts are pre-arranged for the connection of two additional ventilation outputs, by putting an OPTIONAL kit
ventilation, see chapter 21
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 12 cm diameter and related openings.
b) Fasten the hoses using the clamps to the related collars and openings, after having removed the semi-blank
caps.
c) Each pipe must not exceed 1.5 m of length for natural ventilation and 4 m for forced ventilation; it must be
insulated with insulating materials to avoid noise and dispersion of heat.
d) The openings must be positioned at a height not lower than 2 m from the floor to avoid that hot air at output
meets people.
e) If the space between the upper part of the insert and the lower profile of the hood is lower than 10 cm, it is
necessary to perform a hole of about 30 x 40 cm on the hood to allow the fastening of the hoses (see Picture 11
– Picture 12).
f) The OPTIONAL ventilation kit has to be installed below the appliance in the rear part (see instructions in chapter
21). As consequence you should arrange a underlying space to collocate it, allowing a proper air flow and the
accessibility for future maintenance.

CONNECTION TO THE FLUE / AIR FOR COMBUSTION (air intake)

The connection to the stack must be performed with stiff pipes in aluminized steel with a minimum thickness of 2 mm
or in 316 stainless steel with a minimum thickness of 1 mm.
It is forbidden to use metallic pipes or pipes in asbestos cement since they jeopardize the safety of the fitting
itself, considering that they are subject to tears or breaks resulting in leaks of smoke.
