ENGLISH
- 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everysystempipingcarefullyinorderto
removeanyresiduesthatmayimpairtheoperationoftheappliance.
Underthesafetyvalve,installawatercollectingfunnelwiththe
corresponding discharge in the event of leaks due to the overpres-
sureoftheheatingsystem.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 ele-
ments must be airtight.
ANTI-FREEZE SYSTEM
Theboileristtedasstandardwithanautomaticanti-freezesystem
thatactivateswhenthetemperatureofthewaterintheprimary
circuitfallsbelow6°C.Thissystemisalwaysactive,guaranteeing
boiler protection to an outdoor temperature level of -3 °C. To take
advantageofthisprotection(basedonburneroperation),theboiler
mustbeabletoswitchitselfon;anylockoutcondition(e.g.lackof
gas/electricitysupply,orsafetydeviceintervention)thereforedeac-
tivates the protection.
Theanti-freezeprotectionisalsoactivewhentheboilerisonstandby.
In normal operation conditions, the boiler can protect itself against
freezing. If the machine is left unpowered 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specic,good
qualityanti-freezeliquidtotheprimarycircuit.Carefullyfollowthe
manufacturer'sinstructionswithregardsnotonlythepercentageof
anti-freeze 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cir-
cuit.Theboilercomponentmaterialsareresistanttoethyleneglycol
based anti-freeze liquids.
3.2 Securing the boiler to the wall and hydraulic connections
Tofastentheboilertothewall,usethecardboardtemplate(g.
4-5)inthepackaging.Thepositionandsizeofthehydrauliccon-
nections are indicated below:
A CHreturn 3/4”
B CHdelivery 3/4”
C gasconnection 3/4”
D DHWoutput 1/2”(forC.S.I.)-3/4”(forR.S.I.)
E DHWinput 1/2”(forC.S.I.)-3/4”(forR.S.I.)
IncaseofreplacementofBerettaboilersfromprevioustype,there
isanadaptationkitofhydraulicconnectionsavailable.
3.3 Electric connection
Theboilersleavethefactorycompletelywiredwiththepowercable
alreadyconnectedandtheyonlyneedtheconnectionoftheambient
thermostat(AT)tobecarriedoutinthespecicterminals.
To access the terminal board:
-turnoffthesystemgeneralswitch
-undothexingscrews(A)oftheshell(g.6)
- move forward and then upwards the shell base to unhook it from the
chassis
-undothexingscrews(B)oftheinstrumentpanel(g.7)
- turn the instrument panel upside down
-removetheterminalboardcover(g.8)
-insertthecableofthepossibleT.A.(g.9)
The ambient thermostat must be connected as indicated on the
wiring diagram.
Ambient thermostat input in safety low voltage (24 Vdc).

Theconnectiontothemainssupplymustbecarriedoutthrougha
separationdevicewithanomnipolaropeningofatleast3.5mm(EN
60335-1,categoryIII).
The appliance operates with an alternating current of 230 Volt/50 Hz
and an electrical power of 100W for 20 C.S.I. - 115W for 24 C.S.I.
and24R.S.I.(andcomplieswiththestandardEN60335-1).
 Itiscompulsorytocarryoutconnectionwithanefcientearth
circuit, according to national and local legislation.
 Itisadvisabletocomplywithneutralphaseconnection(L-N).
The earth wire must be a couple of centimetres longer than the
others.
Do not use gas and/or water pipes to earth electrical ap-
pliance.
Themanufacturerdeclinesliabilityforanydamageiftheappliance
was not connected to an earth circuit.
Use the power cable supplied to connect the boiler to the mains power
supply.
If the power cable is replaced, use a cable type HAR H05V2V2-F,
3 x 0.75 mm
2
, 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lter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
For fumes exhaustion, refer to the current local and national regula-
tions.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uegasoutlet/airsuctionkit,sinceitispossibletouse
the accessories for appliance with a forced draught sealed chamber
that better adapts to the installation characteristics.
Itisessentialforuegasreleaseandtherestorationofboilercom-
bustionairtousecertiedpipesandthatconnectioniscarriedout
correctlyasindicatedbytheinstructionssuppliedwiththeuegas
accessories.
Withonlyonesmokepipeyoucanconnectmorepiecesofappli-
anceprovidedthateverypieceofapplianceissealedchambertype.
“FORCED OPEN” INSTALLATION (TYPE B22P/B52P)
Fumes outlet duct Ø 80 mm (g. 10a)
The fumes outlet duct can be aimed in the most suitable direction for
installation needs. To install follow the instructions supplied with the kit.
 Inthisconguration,theboilerisconnectedtotheØ80mm
fumesoutletductbymeansofaØ60-80mmadaptor.
In this case, the combustion supporting air is taken from the
room in which the boiler is installed, which must be a suitable
and ventilated technical room.
Non-insulated fumes outlet ducts are potential sources of
danger.
Whennecessary,theuegasange(F)mustberemovedusinga
screwdriver as a lever.
Theboilerautomaticallyadaptsventilationaccordingtothetypeof
installation and the length of the duct.
