Suction pipe length (m)
Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80
Thanks to the boiler characteristics, a flue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
For the ducting, you are advised to make a project calculation in
order to respect the relevant standards in force.
The table shows the standard configurations allowed.

(*) Use flue gas system accessories in plastic (PP) for condensing boilers:
Ø50 and Ø80 H1 class and Ø60 P1 class.
The boilers are factory set to:
25 C.S.I.: 4.900 r.p.m. (CH) and 6.100 r.p.m. (DHW) and the maximum
length that can be reached is 7 m for the ø 50 pipe, 25 m for the ø 60 pipe
and 75 m for the ø 80 pipe.
30 C.S.I.: 5.300 r.p.m. (CH) and 6.200 r.p.m. (DHW) and the maximum
length that can be reached is 5 m for the ø60 pipe and 67 m for the ø 80
pipe (not applicable for the ø 50 pipe).
Should it be necessary to achieve greater lengths, compensate the pres-
sure drop with an increase in the r.p.m.of the fan, as shown in the adjust-
ments table, to ensure the rated heat input.
The minimum calibration is not modified.

(*) Use fumes exhaust plastic systems (PP) for condensing boilers.
(**) Maximum installable length ONLY with exhaust pipes in H1 class.
Configurations Ø50 or Ø60 or Ø80 show test data verified in the laboratory.
In the case of installations that differ from those indicated in the "stand-
ard configuration" and "adjustments" tables, refer to the equivalent linear
lengths below.
In any case, the maximum lengths declared in the booklet are guar-
anteed, and it is essential not to exceed them.
