16. INSTALLING THE FLUE AND AIR DUCTS
Model 24 BIC FF
The boiler is easy and flexible to install thanks to the extensive range of available
accessories, as described below.
The boiler has been designed for connection to a vertical or horizontal coaxial
flue-air duct. A splitting kit is also available if separate ducts are required.
Only accessories supplied by the manufacturer must be used for installation!
WARNING: To optimise operating safety, make sure the flue ducts are firmly
fixed to the wall with suitable brackets.
... COAXIAL FLUE-AIR DUCT (CONCENTRIC)
This type of duct is used to discharge exhaust fumes and draw combustion air
both outside the building and if a LAS flue is fitted.
The 90° coaxial curve allows the boiler to be connected to a flue-air duct in any
direction as it can be rotated by 360°. It can also be used as a supplementary
curve combined with a coaxial duct or a 45° curve.

14. DIMENSIONI CALDAIA
If fumes are discharged outside the building, the flue-air duct must protrude
at least 18 mm from the wall to allow an aluminium weathering surround to be
fitted and sealed to avoid water infiltrations.
Make sure there is a minimum upward slope towards the outside of 1 cm per
metre of duct.
•
A 90° curve reduces total duct length by 1 metre.
•
A 45° curve reduces total duct length by 0.5 metres.
The first 90° curve is not considered when calculating the maximum avai-
lable length.
