POSSIBLE OUTLET CONFIGURATIONS (fig. 11)
B23P-B53P - Suction in room, with external outlet.
C13-C13x - Concentric wall outlet. Pipes can leave the boiler
independently, but the outputs must be concentric or near enough in
order to be subjected to similar wind conditions (within 50 cm)
C33-C33x - Concentric roof outlet. Output as C13.
C43-C43x - Discharge and suction in common, separate smoke
pipes, but subjected to similar wind conditions.
C53-C53x - Separate wall or roof outlet and suction line and in areas
with different pressures. Outlet and suction line must never be placed
on opposite walls.
C63-C63x - Outlet and suction line carried out with pipes marketed
and certified separately (1856/1).
C83-C83x - Outlet in single or regular smoke pipe and wall suction line.
C93-C93x - Discharge on the roof (similar to C33) and air suction
from a single existing smoke pipe.
See the prevailing standards.
"FORCED OPEN" INSTALLATION (TYPE B23P/B53P)
Flue gas discharge pipe ø 80 mm (fig. 12)
The flue gas outlet pipe can be directed to the most suitable direction
according to installation requirements. For installation, follow the
instructions supplied with the kit.
In this configuration, the boiler is connected to the flue gas outlet pipe
of ø 80 mm through an adaptor of ø 60-80 mm.
In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room with
proper ventilation).
The non insulated flue gas outlet pipes are potential sources of
danger.
Arrange the flue 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.

"AIRTIGHT" INSTALLATION (TYPE C)
The boiler must be connected to concentric or twin flue gas discharge
pipes and air suction pipes, both leading outdoors. The boiler must
not be operated without them.
Concentric pipes (Ø 60-100 mm) (Fig. 13)
The concentric pipes can be fitted in most suitable direction in
relation to installation requirements complying with the maximum
lengths show on the table.
Arrange the flue 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.

Concentric pipes (Ø 80-125 mm) (Fig. 14)
For this configuration the specific adaptor kit must be installed. The
concentric pipes can be fitted in most suitable direction in relation
to installation requirements. For installation, follow the instructions
supplied with the specific kits for condensing boilers.

Twin pipes (Ø 80 mm) (Fig. 15)
The twin pipes can face in the direction most suitable for installation
requirements. For installation, follow the instructions supplied with
the specific accessory kit for condensation boilers.
Arrange the flue 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.
For the maximum length indications of the individual pipe see
the graphics (fig. 16).
The use of longer pipes reduces the boiler output.

Ø 80 twin pipes with Ø 50, Ø 60, Ø 80 pipework (Fig. 17)
The characteristics of the boiler allow the Ø 80 flue gas discharge
pipe to be connected to the Ø 50, Ø 60 and Ø 80 range of pipework.
For the pipework we recommend carrying out a design
calculation in order to comply with the applicable prevailing
standards.
The allowed base configurations are indicated in the table.

(*) Use the plastic (PP) flue accessory systems for condensing
boilers that can be found on the residential catalogue price list, ø 50
H1 class and ø 60 P1 class.
The boilers leave the factory regulated to:
20 R.S.I.: 4.500 r.p.m. for domestic hot water and for heating and the
maximum achievable length is 2.9m for the pipe ø 50, 12.4m for the
pipe ø 60 and 80.0m for the pipe ø 80.
28 C.S.I.: 6.100 r.p.m. for domestic hot water and 4.500 r.p.m. for
heating and the maximum achievable length is 0,5m for the pipe ø
50, 6m for the pipe ø 60 and 35m for the pipe ø 80.
If you need to reach greater lengths compensate for the pressure
drop with an increase of the number of fan rotations as shown in the
adjustments table in order to guarantee the rated heat input.
The minimum calibration must not be modified.
If the prevailing value is greater than 200 Pa the law requires the use
of H1 pressure class flue accessories.
