"Forced Open" Installation (Type B23P/B53P) - Beretta Quadra Green CSI Series Installer And User Manual

QUADRA GREEN C.S.I.
3.12 Flue gas discharge and air suction
Observe local legislation regarding fl ue gas discharge.
Flue gases are discharged from a centrifugal fan located inside the combus-
tion chamber and the control board constantly checks that this is working
correctly. The boiler is supplied without the fl ue gas discharge/air suction kit,
since it is possible to use the accessories for appliance with a forced draught
sealed chamber that better adapts to the installation characteristics. For fl ue
gas extraction and the restoration of boiler combustion air, it is essential to
only use certifi ed piping. Connection must be carried out correctly as indicated
in the instructions supplied as standard with the fl ue gas accessories.
Multiple appliances can be connected to a single smoke pipe provided that
each is a sealed chamber-type appliance. The boiler is a Type C appliance
(sealed chamber), and must therefore have a safe connection to the fl ue
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.
The maximum lengths of the ducts refer to fl ue systems available in
the catalogue.
Straight length means comprehensive of the fi rst curve (connection
in the boiler), terminals and junctions. An exception is made for the
vertical Ø 60-100 mm concentric pipe, whose straight length does
not include curves.
POSSIBLE OUTLET CONFIGURATIONS (fi g. 24)
B23P/B53P Suction indoors and discharge outdoors
C13-C13x Discharge via concentric wall outlet. The pipes may leave the
boiler independently, but the outlets must be concentric or suffi -
ciently close together to be subjected to similar wind conditions
(within 50 cm).
C33-C33x Discharge via concentric roof outlet. Outlets as for C13.
C43-C43x Discharge and suction in common separate smoke pipes, but
subjected to similar wind conditions.
C53-C53x Separate discharge and suction lines on wall or roof and in ar-
eas with diff erent pressures. The discharge and suction lines
must never be positioned on opposite walls.
C63-C63x Discharge and suction lines using pipes marketed and certifi ed
separately (1856/1).
C83-C83x Discharge via single or common smoke pipe and wall suction line.
C93-C93x Discharge on roof (similar to C33) and air suction from a single
existing smoke pipe.

"FORCED OPEN" INSTALLATION (TYPE B23P/B53P)

Flue gas discharge pipe ø 80 mm (fi g. 20)
The fl ue gas discharge pipe can be directed to the most suitable direction
according to installation requirements. For installation, follow the instruc-
tions supplied with the kit. In this confi guration, the boiler is connected to
the fl ue gas discharge pipe (ø 80 mm) through an adaptor (ø 60-80 mm).
In this case, the combustion air is picked up from the boiler instal-
lation room (which must be a suitable technical room with proper
ventilation).
Uninsulated fl ue discharge outlet pipes are potential sources of
danger.
Arrange the fl ue gas discharge pipe so it slopes by 3° towards the
boiler.
The boiler automatically adapts the purging to the type of installation
and the length of the pipe.

"SEALED" INSTALLATION (TYPE C)
The boiler must be connected to concentric or twin fl ue gas discharge pipes
and air suction pipes, both leading outdoors. The boiler must not be oper-
ated without them.
Concentric pipes (ø 60-100 mm) (fi g.21)
The concentric pipes can be placed in the most suitable direction according
to installation requirements, complying with the maximum lengths indicated
in the table.
Arrange the fl ue gas discharge pipe so it slopes by 3° towards the
boiler.
Non-insulated outlet pipes are potential sources of danger.
The boiler automatically adapts the purging to the type of installation
and the length of the pipe.
Do not obstruct or choke the combustion air suction pipe in any way.
For installation, follow the instructions supplied with the kit.

Twin pipes (ø 80 mm) (fi g. 22-23)
The twin pipes can face in the direction most suited to the installation re-
quirements. For installation, follow the instructions supplied with the spe-
cifi c accessory kit for condensing boilers.
To use the combustion air suction pipe, one of the two inlets (A and B) must
be selected. Remove the closure plug which is fi xed using screws, and use
the specifi c adaptor relating to the inlet selected (C air inlet adaptor ø 80 - D
air inlet adaptor from ø 60 to ø 80) available as an accessory.
Arrange the fl ue gas discharge pipe so it slopes by 3° towards the
boiler.
The boiler automatically adapts the purging to the type of installation
and the length of the pipes. Do not obstruct or choke the pipes in
any way.
Refer to the graphs to fi nd the maximum lengths of the single pipe.
The use of longer pipes reduces the boiler output.

Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80
Thanks to the boiler characteristics, a fl ue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
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 confi gurations allowed.
