Gas Connection - Beretta Ciao 24 C.A.I. e Manuel D'utilisation

If the power cable is replaced, use a cable type HAR H05V2V2-
F, 3 x 0.75 mm2, with max. outside diameter 7 mm.

3.4 Gas connection

Before connecting the appliance to the gas network, check that:
- national and local regulations are complied
- the gas type is the one suitable for the appliance
- the piping is clean.
The gas pipe must be installed outdoor. If the pipe goes through the
wall, it must go through the central opening, in the lower part of the
template. It is advisable to install a filter of suitable dimensions on
the gas line if the distribution network had solid particles.
Once the appliance has been installed check that connections are
sealed according to current installation regulations.
3.5 Fumes exhaustion and air suction (CIAO C.S.I. e)
For fumes exhaustion, refer to the current local and national regu-
lations. Always comply with local standards of the Fire Department,
the Gas Company and with possible municipal dispositions.
The release of combustion products is assured by a centrifugal fan
placed inside the combustion chamber and its correct operation
is constantly checked by a pressure switch. The boiler is supplied
without the flue gas outlet/air suction kit, since it is possible to use
the accessories for appliance with a forced draught sealed cham-
ber that better adapts to the installation characteristics.
It is essential for flue gas release and the restoration of boiler
combustion air to use certified pipes and that connection is car-
ried out correctly as indicated by the instructions supplied with the
flue gas accessories. With only one smoke pipe you can connect
more pieces of appliance provided that every piece of appliance is
sealed chamber type.
CONCENTRIC OUTLETS (ø 60-100)
The boiler has been designed to be connected to concentric outlet/
suction pipes and with the opening for air suction (E) closed (fig.
10). The concentric outlets can be places in the most suitable di-
rection according to room requirements, complying with the maxi-
mum lengths indicated in the table. For installation, follow the in-
structions supplied with the kit. According to the length of the pipes
used, it is necessary to insert a flange, selecting one from those
contained in the boiler (see the following table). When necessary,
the flue gas flange (F) must be removed using a screwdriver as a
lever. The table indicates the permitted linear lengths. According to
the length of the pipes used, it is necessary to insert a flange, select-
ing one from those contained in the boiler (see the following table).

To direct the outlets in the most suit-
able installation way (right air input)
there is an air/flue gas splitter kit
available.

To use the combustion air suction pipe, one of the two inlets (G and
H) must be selected. Remove the closure plug which is fixed using
screws, and use the specific adaptor relating to the inlet selected.
The air inlet adaptor ø 80 (X) must be correctly oriented, it is
therefore necessary to fix it using the appropriate screws, so
that the locating tab does not interfere with the casing: X air
inlet adaptor ø 80 - Y air inlet adaptor from ø 60 to ø 80.
When necessary, the flue gas flange (F) must be removed using
a screwdriver as a lever. The table indicates the permitted linear
lengths. According to the length of the pipes used, it is necessary
to insert a flange, selecting one from those contained in the boiler
(see the following table).
