2.11.2 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.
