2.12.2 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.
