ENGLISH
The boilers produced in our plants are built with great attention to
detail and every component is checked in order to protect users
and installers from injury. After working on the product, quali
fi ed
personnel must check the electrical wiring, in particular the stripped
part of conductors, which must not stick out from the terminal board,
avoiding possible contact with live parts of said conductor.
This instruction manual, together with the user manual, are integral
parts of the product: make sure it remains with the appliance, even
if it is transferred to another owner or user, or moved to another
heating system. In case of loss or damage, please contact your local
Technical Assistance Service for a new copy.
Boiler installation and any other assistance and maintenance opera-
tions must be carried out by quali
fi ed personnel according to the
provisions of the legislation in force.
The installer must instruct the user about the operation of the appli-
ance and about essential safety regulations.
This boiler must only be used for the application it was designed for.
The manufacturer declines all contractual and non-contractual liability
for injury to persons or animals or damage to property deriving from
errors made during installation, adjustment and maintenance and
from improper use.
After removing the packaging, make sure the contents are in good
condition and complete. Otherwise, contact the dealer from whom
you purchased the appliance.
The safety valve outlet must be connected to a suitable collection
and venting system. The manufacturer declines all liability for any
damage caused due to any operation carried out on the safety valve.
Dispose of all the packaging materials in the suitable containers at
the corresponding collection centres.
Dispose of waste by being careful not to harm human health and
without employing procedures or methods which may damage the
environment.
During installation, inform the user to:
- in the event of water leaks, the water supply must be shut off and
the Technical Assistance Service must be contacted immediately.
- it is necessary to periodically check that the operating pressure of
the hydraulic system is above 1 bar. If necessary, reset the pres-
sure as indicated in the paragraph entitled “Filling the system”
- if the boiler is not used for a long time, the following operations are
recommended:
- turn the main switch of the appliance and the main switch of the
system to the “off” position
- close the fuel and water taps of the heating system
- drain the heating system to prevent freezing.
For safety, always remember that:
the boiler should not be used by children or unassisted disabled
people
it is dangerous to activate electrical devices or appliances (such as
switches, home appliances, etc.) if you smell gas or fumes. In the
event of gas leaks, ventilate the room opening doors and windows;
close the main gas tap; contact the Technical Assistance Service or
professionally quali
fi ed personnel immediately
do not touch the boiler while barefoot, or if parts of your body are
wet or damp
before any cleaning operations, disconnect the boiler from the mains
power supply by turning the two-position system switch and the main
control panel switch to the “OFF” position
do not modify safety and adjustment devices without the manufac-
turer’s permission and relative instructions
do not pull, disconnect or twist the electric cables coming out of the
boiler, even when it is disconnected from the mains power supply
avoid covering or reducing the size of the ventilation openings in the
installation room
do not leave in fl ammable containers and substances in the installa-
tion room
keep packaging materials out of the reach of children
it is forbidden to obstruct the condensate drainage point.
2 - DESCRIPTION
Ciao Green R.S.I. is a Type C wall-mounted condensing boiler capable
of operating under different conditions through a series of jumpers on the
electronic board (as described in “Con
fi guring the boiler”):
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 con-
nected: in this condition, with every heat request from the storage tank ther-
mostat, the boiler supplies hot water for the preparation of the domestic
hot water.
MODE C
heating only, with the connection of an external storage tank (accessory kit
available upon request) (managed by a temperature probe) for preparing
domestic hot water. When connecting the storage tank not supplied by us,
make sure that the NTC probe has the following characteristics: 10 kOhm
at 25°C, B 3435 ±1%.
According to the
fl ue gas discharge device, the boiler is classi fi ed in catego-
ries B23P, B53P, C13, C23, C33, C43, C53, C63, C83, C93, C13x, C33x,
C43x, C53x, C63x, C83x, C93x.
In con
fi guration B23P and B53P (when installed indoors), the appliance
cannot be installed in bedrooms, bathrooms, showers or where there are
open
fi replaces without a proper air fl ow. The room where the boiler is in-
stalled must have proper ventilation.
In con
fi guration 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
3.1 - Installation regulations
Installation must be carried out by quali fi ed personnel, in accordance with
local regulations.
POSITION
The boiler has protection that guarantees correct operation with a tempera-
ture range from 0°C to 60°C.
To take advantage of protective devices, the appliance must be able to start
up, since any lockout condition (for example, absence of gas or electrical
supply, or safety operation) deactivates the protective devices. If the ma-
chine is left powered down for long periods in areas where temperatures
may fall below 0°C, and you do not want to drain the heating system, you
are advised to add a good quality antifreeze liquid to the primary circuit
to protect it from freezing. Carefully follow the manufacturer’s instructions
with regards not only the percentage of antifreeze liquid to be used for the
minimum temperature at which you want to keep the machine circuit, but
also the duration and disposal of the liquid itself. For the domestic hot water
part, we recommend you drain the circuit.
The boiler component materials are resistant to ethylene glycol based an-
tifreeze liquids.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance opera-
tions, respect the minimum clearances foreseen for installation (
fi g. 9).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave in
fl ammable products in the room where the boiler is installed
- heat sensitive walls (for example, wooden walls) must be protected with
proper insulation.
IMPORTANT
Before installation, wash all system piping carefully in order to remove any
residues that may impair the operation of the appliance.
Connect the drain manifold to a suitable drainage system (for details, refer
to chapter 3.5). The domestic hot water circuit does not need a safety valve,
but make sure that the pressure of waterworks does not exceed 6 bar. In
case of doubts, install a pressure reducer. Prior to ignition, make sure that
the boiler is designed to operate with the gas available; this can be checked
by the message on the packaging and the adhesive label indicating the gas
type. It is very important to highlight that in some cases the smoke pipes are
under pressure and therefore, the connections of several elements must
be airtight.
In some parts of the manual, some symbols are used:
WARNING = for actions requiring special care and adequate preparation
FORBIDDEN = for actions that MUST NOT be performed
