6.12.2 Separate ducts (Ø 60mm and Ø 80mm)
Constructing outlets for separate ducts indicates the use of the
"air-flue split pipe system". This is to be ordered separately
from the boiler and when connected to the other accessories,
from those listed in the table below, completes the smoke-
outlet/ combustion air inlet assembly.

CAUTION
– The maximum total length of the ducts , obtained by
adding the lengths of the inlet and outlet pipes,
is determined by the load losses of the individual
accessories used and
must not exceed 15 mm H2O
.
–
For all boiler versions, the total extension
must not
in any case exceed 25 m (inlet) + 25 m (outlet) for
ducts Ø 80 mm . The total extension must not exceed
6 m (inlet) + 6 m (outlet) for ducts
Ø 60 mm
, even if
the total load loss is less than the maximum which
can be applied.

NOTE:
for the boiler to operate correctly it is necessary that a
minimum distance of 0.50 m of the duct is respected with a 90°
inlet curve.
