2 - BOILER DESCRIPTION

Ciao S C.S.I. is a C-type wall-mounted boiler for heating and pro-
duction of domestic hot water: according to the flue gas outlet de-
vice, the boiler is classified in categories B22P, B52P, C12, C22,
C32, C42, C52, C62, C82, C92, C12x, C32x, C42x, C52x, C62x,
C82x, C92x.
Ciao S R.S.I. is a Type C wall-mounted boiler that can function in
various mode:
MODE A
Heating only without any external storage tank connected.
The boiler does not supply domestic hot water.
MODE B
Heating only with a thermostatically controlled external storage
tank connected: in this condition, with every heat request from the
storage tank thermostat, the boiler supplies hot water for the prepa-
ration of the domestic hot water.
MODE C
Heating only, with the connection of an external storage tank (ac-
cessory kit available upon request) (managed by a temperature
probe) for preparing domestic hot water. When connecting the stor-
age tank not supplied by us, make sure that the NTC probe has the
following characteristics: 10 kOhm at 25°C, B 3435 ±1%
In configuration B22P and B52P (when installed indoors), the ap-
pliance cannot be installed in bedrooms, bathrooms, showers or
where there are open fireplaces without a proper air flow. The room
where the boiler is installed must have proper ventilation.
In configuration C, the appliance can be installed in any type of
room and there are no limitations due to ventilation conditions or
room volume.

3 - INSTALLATION REGULATIONS

POSITION
Ciao S can be installed indoors (fig. 2).
The boiler has protection that guarantees correct operation with a
temperature range from 0°C to 60°C.
To take advantage of protections, the appliance must be able to
start up, since any lockout condition (for example, absence of gas or
electrical supply, or safety intervention) deactivates the protections.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance
operations, respect the minimum spaces foreseen for installation
(fig. 3).
