Observeapplicablelegislationregardinguegasexhaustion.
Theexhaustsystemmustbemadeusingrigidducting,thejoints
betweenelementsmustbehermeticallysealedandallcomponents
must be resistant to heat, condensation and mechanical stress and
vibration.
Non insulated outlet pipes are potential sources of danger.
The apertures for the combustion air must be realised in compli-
ance with applicable legislation. If condensation forms, the exhaust
duct must be insulated. Figure 12 shows a top-down view of the
boilerwiththedimensionsfortheuegasexhaustoutlet.
Flue gas safety system
Theboilerfeaturesasystemmonitoringthatuegasesarecor-
rectlyexhausted which arreststhe boiler in the event of a fault:
uegasthermostat,g.11b.Torestorenormaloperation,turnthe
function selector to
(3g.1a),waitafewseconds,thenturnthe
function selector into the desired position.
If the fault persists, call a qualied technical from the Technical
SupportService.Theuegasexhaustionmonitoringsystemmust
neverbebypassedorrenderedinoperable.Useonlyoriginalre-
placementpartswhenreplacingthewholesystemorfaultysystem
components.
3.6 Filling the heating system (g. 13)
Oncethehydraulicconnectionshavebeencarriedout,lltheheat-
ingsystem.Thisoperationmustbecarriedoutwithcoldsystem
following this instructions:
-turnbytwoorthreeturnstheautomaticreliefvalvecap(I)
- make sure the cold water inlet tap is open
-turnonthellingtap(Lg.13)untilthepressureindicatedbythe
water pressure gauge is between 1 and 1.5 bar.
Oncellingiscomplete,closethellingtap.
Theboilerhasanefcientairseparatorsonomanualintervention
isneeded.The burner switches on only if the air reliefphaseis
nished.
3.7 Emptying the heating system
Toemptythesystem,proceedasfollow:
- switch off the boiler
- loosetheboileroutlettap(M)
- emptythelowestpointsofthesystem.
3.8 Emptying the domestic hot water
Whenthereisriskoffrost,thedomestichotwatersystemmustbe
emptiedinthefollowingway:
- close the main tap of the water mains
- open all the hot and cold water taps
-emptythelowestpoints.
WARNING
Whencarryingoutthedischargeofthesafetyvalve(N),itmustbe
connectedtoasuitablecollectionsystem.Themanufacturerisnot
responsibleforpossibledamagesduetosafetyvalveoperation.
4 - IGNITION AND OPERATION
4.1 Preliminary checks
Firstignitioniscarriedoutbycompetentpersonnelfromanautho-
rised Technical Assistance Service Beretta.
Before starting up the boiler, check:
a) thatthesupplynetworksdata(electric,water,gas)corresponds
to the label data
b) thatpipingleavingtheboileriscoveredbythermalinsulation
sheath
c) thatuegasextractionandairsuctionpipesworkcorrectly
d) thatconditionsforregularmaintenanceareguaranteedifthe
boiler is placed inside or between furniture
e) thesealofthefueladductionsystem
f) thatfuelcapacitycorrespondstovaluesrequestedbytheboiler
g) thatthefuelsupplysystemhasthecorrectcapacityforthenec-
essarycapacitytotheboilerandthatithasallthesafetyand
controldevicesprescribedbycurrentregulations.
4.2 Appliance ignition
Tostart-uptheboileritisnecessarytocarryoutthefollowingop-
erations:
- power the boiler
- openthegastappresentinthesystemtoallowfuelow
- turnthemodeselector(3-g.1a)tothedesiredposition:

ing. If there is a heat request, the boiler switches on and the digital
monitor indicates the heating water temperature, the icon to indi-
cateheatingandtheameicon(g.3a).Ifthereisadomestichot
waterrequest,theboilerswitchesonandthedigitaldisplayshows

tersupplyandtheameicon(g.4a)
Adjustment of domestic hot water temperature
Toadjustdomesticwatertemperature(bathrooms,showers,kitch-
en,etc.), turn the knobwith symbol
(g. 2b) within thearea
marked + and -.
Theboilerisstandbystatusuntil,afteraheatrequest,theburner
switcheson and the digital display shows thehot water system
temperature, the icon to indicate the hot water supply and the
ameicon.
The boiler will be in function until the adjusted temperature is
reached,afterwardsitwillbein“standby”again.
Environment Automatic Adjustment System Function
(S.A.R.A.) g. 6a
By setting the heating water temperature selector to the area
marked by AUTO - temperature value from 55 to 65°C -  the
S.A.R.A.self-adjusting system isactivated: the boilervaries the
deliverytemperatureaccordingtotheclosingsignaloftheroom
thermostat. When the temperature set with the heating water tem-
perature selector is reached, a 20 minutes count begins. If during
this period the room thermostat still requests heat, the value of the
settemperatureautomaticallyincreasesby5°C.
When the new value is reached, other 20 minutes count begins.
If during this period the room thermostat still requests heat, the
valueofthesettemperatureautomaticallyincreasesby5°C.
This new temperature value is the result of the temperature set
manuallywiththeheatingwatertemperatureselectorandthein-
crease of +10 °C of the S.A.R.A function.
After the second increasing cycle, the temperature value is re-
storedtothevaluesetbytheuserandtheabovementionedcycle
