2.12.2 Separate ducts (split pipe system Ø 80mm)
Constructing outlets for separate ducts indicates the use of
the "air-smoke split pipe system". This is to be ordered se-
parately 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 .
– The total extension must not in any case exceed 50 m
even if the total load loss is less than the maxi-
mum which can be applied.
