Twin pipes (ø 80 mm)
The combustion air suction pipe should be selected from the two inputs,
remove the closing plug fi xed with the screws and fi x the specifi c air
defl ector.
Position the adaptor on the fl ue gases pipe so that the Ø 60 pipe goes fully
up against the fl ue gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the fl ange 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
fl ange 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 fl ue gases
turret of the boiler.
Once positioned, make sure that the 4 notches (A) on the fl ange 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
fl ange so the adaptor itself is restrained.

Coaxial pipes (ø 80-125 mm)
- Place the adaptor vertical attachment so that the Ø 60 pipe goes fully up
against the fl ue gases turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the fl ange 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
fl ange so the adaptor itself is restrained.
- Then fi t the Ø 80-125 adaptor kit on the vertical fi tting
Twin pipes with Ø 80 pipework Ø50 - Ø60 - Ø80)
Thanks to the boiler characteristics, a Ø80 fl ue 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 confi gurations allowed.

(*) Use fl ue 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.
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.

The minimum calibration should not be modifi ed.
