When necessary, the flue gas flange (L) must be removed using a screwdriver
as a lever.
The table indicates the permitted linear lengths. According to the length of
the pipes used, it is necessary to insert a flange, selecting one from those
contained in the boiler (see the following table).

TWIN OUTLETS (ø 80)
Twin outlets can be placed in the most suitable direction according to the
room requirements.
The air inlet adaptor (D fig. 23) must be correctly directed, it is
necessary to fasten it with the appropriate screws, so that the
positioning flap does not interfere with the shell.

CONCENTRIC PIPES (ø 80/125)
The boiler has been designed to be connected to concentric outlet/suction
pipes and with the opening for air suction closed.
The concentric outlets can be placed in the most suitable direction according
to room requirements, complying with the maximum lengths indicated in
the table.
For installation, follow the instructions supplied with the kit.
To go through the wall, drill a hole of Ø 130 mm.
According to the length of the pipes used, it is necessary to insert a flange
selecting from those contained in the boiler (see table).

Pay special attention to external temperature and pipe length. Refer to the
diagrams in order to establish if it is compulsory or not to use a condensation
collector.
In case of operation at temperature lower than 60 °C, it is compulsory to
use a condensation collector.
If a condensation collector is used, provide a slope of the flue exhaust pipe
of 1% towards the collector.
Connect the condensation trap syphon to a white water outlet pipe.
Non insulated outlet pipes are potential sources of danger.
To direct the outlets in the most
suitable installation way (right air
input) there is an air/flue gas splitter
kit available

POSSIBLE OUTLET CONFIGURATIONS
B22P-B52P Intake inside and outlet outside
C12 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).
C22 Concentric outlet in regular smoke pipe (suction and outlet in the
same pipe).
C32 Concentric roof outlet. Output as C12.
C42 Outlet and suction line in regular separate smoke pipes, but subjected
to similar wind conditions.
C52 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.
C62 Outlet and suction line carried out with pipes marketed and certified
separately (1856/1).
C82 Outlet in single or regular smoke pipe and wall suction line.
