danger.

duced for vertical ducts (Type C32) or vertical sec-
tions of the duct (Type C42) longer than 1.3m.
Diaphragms for coaxial ducts
Boilers leave the factory equipped with a diaphragm (1) with
the following characteristics:
– Brava Slim 25 BF: diaphragm Ø 79 mm
– Brava Slim 30 BF: diaphragm Ø 81 mm.

2.11.2 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 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.
The total maximum length obtained from the length of the
outlet and inlet pipes is determined by the load loss of the in-
dividual accessories and must not be greater than 9 mm H
