If fumes are discharged outside the building, the lue-air duct must protrude 
at least 18 mm from the wall to allow an aluminium weathering surround to be 
itted and sealed to avoid water iniltrations.
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.

Model 24 BIC FF 

The boiler is easy and lexible 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 
lue-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 lue is itted.
The 90° coaxial curve allows the boiler to be connected to a lue-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.
