Installation of flue and air ducts
(2.24 CF)
We guarantee ease and exibility of installation for a gas-red forced draft boiler thanks
to the ttings and xtures supplied (described below).
The boiler is especially designed for connection to an exhaust ue / air ducting, with
either coaxial, vertical or horizontal terminal. By means of a splitting kit a two-pipe system
may also be installed.
Exclusively
install fittings supplied by the manufacturer.

...coaxial flue - air duct (concentric)
This type of duct allows to disengage exhaust gases and to draw combustion air both
outside the building and in case a LAS ue is tted.
The 90° coaxial bend allows to connect the boiler to a ue-air duct in any direction as it
can rotate by 360°. It can moreover be used as a supplementary bend and be coupled
with a coaxial duct or a 45° bend.
(*) The restrictor must be removed in case the ue duct length exceeds 1 m.
If the ue outlet is placed outside, the ue-air ducting must protrude at least 18mm out
of the wall to allow alluminium weathering tile to be tted and sealed to avoid water
leakages.
Ensure a minimum downward slope of 1 cm towards the outside per each metre of
duct length.
A 90° bend reduces the total duct length by 1 metre.
A 45° bend reduces the total duct length by 0.5 metre.
