b
Arrange the flue gas discharge pipe so it slopes by 3° towards
the boiler.
b
Non-insulated outlet pipes are potential sources of danger.
b
The boiler automatically adapts the purging to the type of
installation and the length of the pipe.
b
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.
b
Arrange the flue gas discharge pipe so it slopes by 3° towards
the boiler.
b
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.
b
For the maximum length indications of the individual pipe see
the graphics (fig. 16).
b
The use of longer pipes reduces the boiler output.

The characteristics of the boiler allow the Ø 80 flue gas discharge
pipe to be connected to the Ø 50, Ø 60
b
For the pipework we recommend carrying out a design
calculation in order to comply with the applicable prevailing
st andards.
The allowed base configurations are indicated in the table.

The boilers leave the factory regulated to 6.100 r.p.m. for domestic
hot water and 4.500 r.p.m. for heating and the maximum achievable
length is 6m for the pipe ø 60, 0,5m for the pipe ø 50 and 80m 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.
b
The mini mum 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

NOTE
If pipes different than those in the Beretta catalogue are used
you must see the ΔP values on the above tables to calculate the
maximum length of the pipes.
The Ø 60 and Ø 50 configurations have experimental, laboratory
checked data.
In the event of installations other than those indicated in the "base

configurations" and "adjustments" table, see the equivalent Ø 80 - Ø
60 or Ø 50 linear lengths shown below.
b
In any case the maximum lengths declared in the booklet are
guaranteed and it is essential that they are not exceeded.

3.11 Filling the heating system (fig. 18-19-20)
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 lower automatic relief valve cap (A) by two or three turns
to allow continuous air venting and leave it open
- ensure that the cold water inlet tap is open
- open the filling tap (C) until the pressure indicated on the water
gauge is between 1 bar and 1.5 bar
- re-close the filling tap.
NOTE
deareation of the boiler takes place automatically by means of the
two automatic A and E bleed valves, the former positioned on the
circulator whereas the latter is positioned inside the air box. If the
deareation phase is difficult, operate as described in section 5.3.
