6.11.2 Separate ducts (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.
The total maximum length, obtained by adding the length of the
outlet and inlet pipes, is determined by the load loss of the indi
-
vidual accessories and must not be greater than 9 mm H
2 O for
Brava Slim 25 BF , 9.5 mm H 2 O for Brava Slim 30 BF and 15 mm
