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 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 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 (inlet)
+ 6 m (outlet) for ducts Ø 60 mm
, even if the total 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 90°
inlet curve.
