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
.
