WARNINGS
– The smoke flue and the connection to the flue pipe
must be in compliance with the national and local
Standards and Legislation in force.
– The use of rigid ducts which are resistant to
temperature, condensate, mechanical stress and
are air-tight is compulsory.
– Outlet ducts which are not isolated are a risk of
danger.

CAUTION
(*) Vertical condensate recovery MUST be introduced
for vertical ducts (Type C32) or vertical sections 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 One 25 BF : diaphragm Ø 79 mm
–
Brava One 30 BF : diaphragm Ø 81 mm.

Fig. 23
When the outlets are Type C12 or C42 the diaphragm is to be
removed or kept following the indications below:

(leave mounted)
< 1 m

When the outlet is Type C32 (vertically straight without any
curves), the presence of the diaphragm modifies the maximum
length of the duct as shown below:
Model Diaphragm Max L (m)
Brava One 25 BF YES 2,5
Brava One 25 BF NO 5
Brava One 30 BF YES 2,5
Brava One 30 BF NO 5
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 from the length of the outlet
and inlet pipes is determined by the load loss of the individual
accessories and must not be greater than 9 mm H
2 O for Brava
One 25 BF
and 9.5 mm H 2 O Brava One 30 BF .
