Do not install the flue gas exhaust near flammable
or plastic materials, whose characteristics can be
changed in the presence of high temperatures.
9
The straight length is intended without bends, and
includes the terminals and joints.
9
The boiler is supplied without the flue gas/air suc-
tion kit, as it is possible to use the accessories for
condensing appliances best suited to the installation
characteristics (refer to the catalogue).
9
In the case of use of non-original flue gas exhaust
and air intake ducts, the use of certified ducts com-
pliant with the appliance to which they are connected
must still be guaranteed, with a temperature class
≥120°C and resistant to condensation.
9
To ensure the best installation safety, attach the pipes
to the wall (or ceiling) using specific fixing brackets
positioned in line with each joint (at a distance such
that the length of each single extension is not exceed-
ed) and immediately before and after every change of
direction (bend).
9
The maximum pipe length values refer to the flue pipe
accessories available in the catalogue.
9
It is compulsory to use specific pipes.
9
The non insulated flue gas outlet pipes are potential
sources of danger.
