“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 rela-
tion 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 in-
stallation 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.

For this configuration the specific adaptor kit must be installed. The

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 ac-
cessory 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 in-
stallation 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.

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 calcula-
tion in order to comply with the applicable prevailing standards.
The allowed base configurations are indicated in the table.

class and ø 60 P1 class
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 achieva-
ble length is 6 m for the pipe ø 60, 0,5 m for the pipe ø 50 and 35
metres 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

NOTE
If pipes different than those in the Beretta catalogue are used you must
see the

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.
In any case the maximum lengths declared in the booklet are
guaranteed and it is essential that they are not exceeded.
