3.6 Air/fume ducts
Warnings
The unit is “type C” with an airtight chamber and forced draught, the air inlet and fume
outlet must be connected to one of the following extraction/suction systems. The unit is
type-approved to work with all the Cxy flue configurations stated on the technical data
plate (some setups are given by way of example in this chapter). It is however possible
that some setups are expressly limited or not permitted by law, standards or local regu-
lations. Before proceeding with installation, check and meticulously observe the above-
mentioned prescriptions. In addition, comply with the provisions concerning the position-
ing of wall and/or roof end pieces and the minimum distances from windows, walls, ven-
tilation openings, etc.
B
This C-type unit must be installed using the fume extraction and outlet ducts
supplied by the manufacturer in accordance with UNI-CIG 7129/92. Failure to
use them automatically forfeits all warranty and liability of the manufacturer.
Baffles
Boiler operation requires fitting the baffles supplied with the unit. Make sure the boiler
has the correct baffle (when used) and that it is properly positioned .

Connection with coaxial pipes
fig. 5 - Examples of connection with coaxial pipes (
= Air /
= Fumes)
Table. 2 - Typology
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions refer to sec. 14. Any horizontal sections of the fume exhaust must
be kept sloping slightly towards the outside, to prevent condensate from flowing back to-
wards the unit.
fig. 6 Starting accessories for coaxial ducts
Before carrying out installation, check with table 3 the baffle to be used and that the max-
imum permissible length is not exceeded, taking into account that every coaxial bend
gives rise to the reduction indicated in the table. For example, a Ø 60/100 duct compris-
ing a 90° bend + 1 horizontal m. has a total equivalent length of 2 m.
