1 - WARNINGS AND SAFETY
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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edpersonnelaccordingtothe
provisionsofthelegislationinforce.
The installer must instruct the user about the operation of the ap-
pliance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li-
ability 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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
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
INSTALLATION MANUAL
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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
thermostat, the boiler supplies hot water for the preparation of the domes-
tic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uegasdischargedevice,theboilerisclassiedincat-
egoriesB23P,B53P,C13,C23,C33,C43,C53,C63, C83, C93, C13x,

IncongurationB23PandB53P(wheninstalledindoors),theappliance
cannot be installed in bedrooms, bathrooms, showers or where there are
openreplaceswithout aproperair ow.Theroom wheretheboiler is
installedmusthaveproperventilation.
IncongurationC,theappliancecanbeinstalledinanytypeofroomand

3 - INSTALLATION
3.1 - Installation regulations
Installationmustbecarriedoutbyqualiedpersonnel,inaccordancewith
localregulations.
POSITION
The boiler has protection that guarantees correct operation with a tem-
perature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 elec-
tricalsupply,orsafetyoperation)deactivatestheprotectivedevices.Ifthe
machine is left powered down for long periods in areas where tempera-
tures 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 cir-
cuit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 dis-
posal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 op-
erations,respecttheminimumclearancesforeseenforinstallation(g.9).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- donotleavein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 indi-
donotleaveinammablecontainersandsubstancesintheinstal-
lation room
keep packaging materials out of the reach of children
it is forbidden to obstruct the condensate drainage point
