2.12.2 Separate ducts (Ø 60mm and Ø 80mm)
Constructing outlets for separate ducts indicates the use of
the "air-smoke split pipe system". This is to be ordered sep-
arately from the boiler and when connected to the other ac-
cessories, 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 ac-
cessories used and must not exceed 15 mm H2O (for
ducts Ø 80mm and Ø 60mm)
– The total extension must not in any case exceed 25 m
(inlet) + 25 m (outlet), for ducts Ø 80 mm, and 6 m (in-
let) + 6 m (outlet) for ducts Ø 60 mm
load loss is less than the maximum which can be
applied.

for the boiler to operate correctly it is necessary that a

minimum distance of 0.50 m of the duct is respected with a
