The minimum length of the pipes must be
less than 0.5 m, whilst the maximum sum
of routes A + B that can be realised with the
aid of extensions must not exceed 40m for
Activ A 18S - Activ A 25S and 25m for Activ
A 30S.
Bends of Ø 80 mm at 90° and at 45° are
available that reduce the maximum total
length of the pipes by:
For the bend of 45° loss
0,9 m
For the bend of 90° loss
1,65 m

If using pipes and terminals by other manu-
facturers (Type C

), it is necessary that
these are approved and in the case of fl ue
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:

Its maximum height with extension is 10m
for Activ A 18S - Activ A 25S and 6m for Ac-
tiv A 30S). Bends of Ø 80 mm at 90° and at
