AIR SUCTION (MIX C.S.I.-MIX R.S.I.)
EXHAUSTION CONFIGURATIONS (fig. 7)
Boiler is homologated for the following exhaustion configurations:
C12 Concentric wall exhaustion. Pipes can separately start from
boiler, but outlets must be concentric or close enough to be
subject to similar wind conditions (within 50 cm)
C22 Concentric exhaustion in common chimney (suction and
exhaustion in the same chimney)
C32 Concentric roof exhaustion. Outlets like C12
C42 Exhaustion and suction in common separate chimneys, but
subject to similar wind conditions
C52 Wall or roof separate exhaustion and suction in different
pressure areas. Exhaustion and suction must never be located
on opposite walls
C62 Exhaustion and suction with separately certified and sold
pipes (1856/1)
C82 Single or common chimney exhaustion and wall suction
Refer to regulations in force for exhaustion of combustion products.
Boiler is provided for without fume exhaustion/air suction kit, since
forced draught sealed chamber accessories can be used, as they
better adapt to installation characteristics.
For fume extraction and burning air restoration in boiler, use origi-
nal pipes or other EC-certified pipes with equivalent characteris-
tics; check connection is correct as shown on instructions fume
accessories provided for with. More appliances can be connected
to a single chimney, provided that all appliances are sealed cham-
ber type.
Boiler is a C-type appliance (sealed chamber) and must be safely
connected to fume exhaustion duct and burning air suction duct,
both getting outside; appliance cannot operate without these ducts.
Concentric outlets (ø 60-100)
Concentric ducts may be placed in the most suitable direction for
installation requirements but special care must be taken as regards
the external temperature and the length of the duct.
Consult the graphs to find out whether a condensate collector is
required.

If the appliance works at temperatures lower than 50 °C (e.g.:
with external probe), the maximum permitted length must be
decreased by 1 metre.
The fumes outlet duct must slope by 1% towards the conden-
sate collector.
The condensate collector can only be applied to the fumes
outlet, within 0.85 m from the boiler; connect the trap of the
condensate collector to a waste water drain.
Uninsulated fumes outlets are potential hazards.
The boiler automatically adapts ventilation according to the type
of installation and the length of the duct. Do not obstruct or narrow
the comburent air inlet duct in any way.

The boiler is furnished predisposed for connection to concentric
discharge/aspiration ducts and with the air aspiration aperture
closed.
The concentric pipes may be oriented in the direction best suited
to the requirements of the premises, respecting the maximum
lengths indicated in the table below.

For installation, follow the instructions provided with the kit.
Execute a Ø 140 mm hole for transit through the wall.
Particular care is required with the external temperature and the
length of the pipe. Refer to the graphics to establish whether the
condensation trap is mandatory or not.
In the case of operation at water temperatures below 60 °C, the
use of a condensation trap is mandatory.
In the case of use of condensation trap the fumes discharge pipe
must be inclined by 1% towards the trap.
