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 provided with a diaphragm (1) with the
following characteristics:
–
GO 18 BF
: diaphragm Ø 79 mm
–
GO 25 BF
: diaphragm Ø 81 mm
–
GO 30.BF
: diaphragm Ø 86 mm.

Fig. 29
When the outlets are
Type C12
or
C42
the diaphragm is to be
removed or kept following the indications below:

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:

6.11.2 Separate ducts (Ø 80mm)
Constructing outlets for separate ducts requires the use of kit
code 8089916 (
GO 18 BF
) and kit code 8089915 (
GO 25 BF
-
GO
30.BF ). This is to be ordered separately from the boiler and when
connected to the other accessories, to be chosen from those
listed in the table, completes the flue gas outlet/ combustion air
inlet assembly.
The total maximum length obtained by adding the lengths of
the outlet and inlet pipes is determined by the load loss of the
individual accessories used and must not be greater than 7 mm
