If using pipes and terminals by other manu-
facturers (Type C
63
), it is necessary that
these are approved and in the case of flue
pipes, it is necessary to use materials com-
patible with condensation products.
During the pipes dimensioning phase, take
into consideration the static pressure resi-
due of the fan:

Extensions are available for reaching the
maximum height.
Its maximum height with extension is 10.
Bends of Ø 80 mm at 90° and at 45° are
available that reduce the maximum total

Pluming kit (Fig. 6.12)
Co-axial ø 60/100 mm + vertical part ø 60
mm (flue outlet).
This kit allows the combustion air to be
sucked up and expel the burnt gases di-
rectly to the outside through a telescopic
co-axial flue (450-950 mm).
