b
It is compulsory to use specific pipes.
b
The non insulated flue gas outlet pipes are potential sources of
danger.
b
The use of a longer pipe causes a loss of output of the boiler.
b
Make sure the flue gas discharge pipe is tilted 3° towards the boiler.
b
The exhaust pipes can face in the direction most suited to the
installation requirements.
b
As envisaged by current legislation, the boiler is designed to take
in and dispose of flue gas condensate and/or meteoric water
condensate deriving from the flue gas discharge system using its
own siphon.
b
if a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to ensure it
operates correctly.
"Forced open" installation (B23P-B53P) (Fig.13)
In this configuration the boiler is connected to the ø 80 mm flue gases
discharge pipe by means of an adaptor.
- Position the adaptor so that the Ø 60 pipe goes fully into the flue gases
turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø 100 of the adaptor.
- Fully tighten the screws (C) that tighten the two locking terminals of the
flange so the adaptor itself is restrained.
Coaxial pipes (ø 60-100 mm) (Fig. 14)
- Position the bend so that the Ø 60 pipe goes fully up against the flue
gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø 100 of the bend.
- Fully tighten the screws (C) that tighten the two locking terminals of the
flange so the bend itself is restrained.
Twin pipes (ø 80 mm) (Fig. 15)
The combustion air suction pipe should be selected from the two inputs,
remove the closing plug fixed with the screws and fix the specific air
deflector.
- Position the adaptor on the flue gases pipe so that the Ø 60 pipe goes
fully up against the flue gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø 100 of the adaptor.
- Fully tighten the screws (C) that tighten the two locking terminals of the
flange so the adaptor itself is restrained.
If the Ø 60-100 to Ø 80-80 splitter kit is used instead of the twin pipe system,
there is a loss in the maximum lengths as shown in the table.
- Place the splitter so that the Ø 60 pipe goes fully up against the flue
gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø 100 of the splitter.
- Fully tighten the screws (C) that tighten the two locking terminals of the
flange so the adaptor itself is restrained.
Loss of length (m)
Coaxial pipes (ø 80-125 mm) (Fig. 16)
- Place the adaptor vertical attachment so that the Ø 60 pipe goes fully up
against the flue gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø 100 of the adaptor.
- Fully tighten the screws (C) that tighten the two locking terminals of the
flange so the adaptor itself is restrained.
- Then fit the Ø 80-125 adaptor kit on the vertical fitting

Twin pipes with Ø 80 pipework (Ø50 - Ø60 - Ø80)
Thanks to the boiler characteristics, a Ø80 flue gas exhaust pipe can be
connected to the Ø50 - Ø60 - Ø80 piping ranges.

For the pipe, you are advised to make a project calculation in order
to respect the relevant regulations in force.
The table shows the standard configurations allowed.

(*) Use flue gas system accessories made of plastic (PP) for condensing
boilers: Ø50 and Ø80 class H1 and Ø60 class P1.
The boilers are factory set to:
25 KIS: 6,200 r.p.m. in heating mode and 7,600 in domestic hot water mode
and the maximum attainable length is 5m for the Ø 50 pipe, 18 m for the Ø
60 pipe and 98 m for the Ø 80 pipe.
30 KIS: 5,800 rpm in heating mode and 6,900 in domestic hot water mode,
and the maximum length that can be reached is 2m for the Ø50 and 11 m
for the Ø60 pipe and 53 m for the Ø80 pipe.
35 KIS: 6,900 rpm in heating mode and 7,800 in domestic hot water mode,
and the maximum length that can be reached is 2m for the Ø50 pipe and 11
m for the Ø60 pipe and 57 m for the Ø80 pipe.
40 KIS: 6,900 rpm in heating mode and 9,100 in domestic hot water mode,
and the maximum length that can be reached is 7m for Ø60 pipe and 42m
for Ø80 pipe (not applicable for Ø50 pipe).
Should greater lengths be required, compensate the pressure drop with
an increase in the r.p.m.of the fan, as shown in the adjustments table, to
provide the rated heat input.
b
The minimum calibration should not be modified.
