The boiler automatically adapts ventilation according to the type
of installation and the length of the duct.
It is compulsory to use specific pipes.
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.
Do not obstruct or choke the combustion air suction pipe in any
way.
For installation, follow the instructions supplied with the kit.

POSSIBLE OUTLET CONFIGURATIONS (fig. 21)
B22P/B52P - Suction in room, with external discharge.
C12-C12x - Concentric discharge on wall. 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 discharge in regular smoke pipe (suction and dis-
charge in the same pipe).
C32-C32x - Concentric discharge on the roof. Outputs as C12.
C42-C42x - Discharge and suction in regular smoke pipes (separated
but subject to similar wind conditions).
C52-C52x - Separated discharge and suction on wall or roof, in areas
with different pressure levels. The discharge and suction lines must
never be placed on opposite walls.
C62-C62x - Discharge and suction using pipes marketed and certified
separately (1856/1).
C82-C82x - Discharge in a single or regular smoke pipe, and suction
on the wall.
C92-C92x - Discharge on roof (similar to C32) and air suction via a
single existing smoke pipe.
Refer to the regulations in force.
For the indication of the maximum lengths of the single pipe, refer to
the following charts.

Twin pipes ø 80 with ducting Ø 60 (fig. 22)
Thanks to the boiler characteristics, a flue gas discharge pipe Ø 80 can
be connected to the ducting ranges Ø 60.
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.

(*) Use flue gas system accessories in plastic (PP) for condensing boilers.
The configurations Ø 60 show test data verified in the laboratory.
In the case of installations that differ from those indicated in the "stand-
ard configuration" tables, refer to the equivalent linear lengths Ø 80 - Ø
60 below.

Extension 0.5m Ø 60
Extension 1.0m Ø 60
Extension 2.0m Ø 60
In any case, the maximum lengths declared in the booklet are
guaranteed, and it is essential not to exceed them.

Filling the heating system (fig. 23)
Once the hydraulic connections have been carried out, fill the heating
system.
This operation must be carried out with a cold system, following these
instructions:
- open the automatic air vent valve cap (A) by two or three turns
- make sure the cold water inlet tap is open
- open the filling tap (B) until the pressure indicated by the water pres-
sure gauge is between 1 and 1.5 bar.
Once filling is complete, close the filling tap.
The boiler has an efficient air separator so no manual intervention is
needed.
