6. VENTILATION HOOD OR ADJACENT LOCAL

The inserts are pre-arranged for the connection of two additional ventilation outputs, by putting an optional
kit ventilation (centrifugal ventilator, art. Nr. 1318000, see chapter 20)
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
Figure 11 – Figure 12).
f) The optional ventilation kit has to be installed below the appliance in the rear part (see instructions in
chapter 20). As consequence you should arrange a underlying space to collocate it, allowing a proper
air flow and the accessibility for future maintenance.

7. 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.
The exhaust pipe must be air-tight fastened to the stack and can have a maximum inclination of 45° ; this to
avoid excessive deposits of condensate produced in the initial start-up phases and/or the excessive
deposit of soot and moreover it avoids the slowing down of the smokes at output.
The failed tightness of the connection can cause the malfunction of the appliance.
The internal diameter of the connection pipe must be equal to the external diameter of the smokes stub
pipe of the appliance. This is assured by pipes complying with DIN 1298.
