Beretta EXCLUSIVE C Installer And User Manual page 5

The boiler is a C-type appliance (with airtight chamber), and must therefore
have a safe connection to the flue gas discharge pipe and to the combustion
air suction pipe; these both carry their contents outside, and are essential
for the operation of the appliance.
Both concentric and twin terminals are available.

b
"Straight length" means with terminals and joints but without bends.
b
The boiler is supplied without the flue gas outlet/air suction kit, since
it is possible to use the accessories for condensing appliances that
better adapt to the installation characteristics (see catalogue).
b
The maximum lengths of the pipes refer to the flue accessories
available in the catalogue.
b
It is compulsory to use specific pipes.
b
The non insulated flue gas outlet pipes are potential sources of
danger.
b
The use of a longer pipe causes a loss of output of the boiler
b
Make sure the flue gas discharge pipe is tilted 3° towards the boiler.
b
As envisaged by current legislation, the boiler is designed to take
in and dispose of flue gas condensate and/or meteoric water
condensate deriving from the flue gas discharge system using its
own siphon.
b
If a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to ensure it
operates correctl.
"Forced open" Installation (type B23P/B53P)
In this configuration the boiler is connected to the ø 80 mm flue gases
discharge pipe by means of an adaptor.
- Position the adaptor so that the Ø 60 pipe goes fully into the flue gases
turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the adaptor.
- Fully tighten the two locking terminals of the flange (C) so the adaptor
itself is restrained.
Concentric pipes (ø 60-100 mm)
- Position the bend so that the Ø 60 pipe goes fully into the flue gases
turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the bend.
- Fully tighten the two locking terminals of the flange (C) so the bend itself
is restrained.
Twin pipes (ø 80 mm) - see graphs fig. 18
The combustion air suction pipe should be selected from the two inputs,
remove the closing plug fixed with the screws and fix the specific air
deflector.
- Position the adaptor on the flue gases pipe so that the Ø 60 pipe goes
fully into the flue gases turret of the boiler
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the adaptor.
- Fully tighten the two locking terminals of the flange (C) so the adaptor
itself is restrained.
Concentric pipes (ø 80-125 mm)
- Position the adaptor so that the Ø60 pipe goes fully into the flue turret
of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the adaptor.
- Fully tighten the two locking terminals of the flange (C) so the adaptor
itself is restrained.
- Then fit the Ø 80-125 adaptor kit on the vertical fitting.

Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80 (fig. 15a)
Thanks to the boiler characteristics, a flue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
b
For the ducting, you are advised to make a project calculation in
order to respect the relevant standards in force.
The table shows the standard configurations allowed.

The boilers are factory set to:
1,5 m
25C n: 5.600 r.p.m. (CH) and 7.900 r.p.m. (DHW) and the maximum length
that can be reached is 6m for the ø 50 pipe, 21m for the ø 60 pipe and 115m
for the ø 80 pipe.
30C n: 6.500 r.p.m. (CH) and 7.900 r.p.m. (DHW) and the maximum length
that can be reached is 4m for the ø 50 pipe, 16m for the ø 60 pipe and 83m
for the ø 80 pipe.
Should it be necessary to achieve greater lengths, compensate the pres-
sure drop with an increase in the r.p.m.of the fan, as shown in the adjust-
ments table, to ensure the rated heat input.
