Suction pipe length (m)
Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80 (fig. 24)
Thanks to the boiler characteristics, a flue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
b
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 7m for the ø 50 pipe, 25m for the ø 60 pipe
and 75m for the ø 80 pipe.
29 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 5m for the ø60 pipe and 67m for the ø 80 pipe
(not applicable for the ø 50 pipe).
Should it be necessary to achieve greater lengths, compensate the pressure
drop with an increase in the r.p.m.of the fan, as shown in the adjustments
table, to ensure the rated heat input.
b
The minimum calibration is not modified.

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 "standard
configuration" and "adjustments" tables, refer to the equivalent linear
lengths below.
b
In any case, the maximum lengths declared in the booklet are
guaranteed, and it is essential not to exceed them.
