INSTALLATION
WARNING!!
THE INSTALLATION AND FIRST IGNITION OF
THE APPLIANCE MUST BE PERFORMED BY
QUALIFIED PERSONNEL IN COMPLIANCE
WITH CURRENT NATIONAL REGULATIONS
REGARDING INSTALLATION, AND IN
CONFORMITY WITH ANY REQUIREMENTS
ESTABLISHED BY LOCAL AUTHORITIES
AND PUBLIC HEALTH ORGANISATIONS.
Before installing the appliance
Theapplianceheatswatertoatemperaturebelowboiling.
It should be connected to a a domestic water mains
supply,thatmustcorrespondinsizetotheperformance
anditspoweroftheappliance.
Beforeconnectingtheappliance,itisrstnecessarytoperform
thefollowingoperations:
- Carefully wash the system piping in order to remove any
screw thread or welding residues, or any dirt which might
preventtheappliancesfromoperatingcorrectly.
- Makesurethattheapplianceissetupforoperationwiththe
typeofgasavailable(readtheinformationonthepackaging
labelandontheboilerdataplate).
-Makesurethattherearenoobstaclesinsideueexhaustand
thatitdoesnotcontainanydischargefromotherappliances,
unless the ue is meant to serve more than one user (in
accordancewithcurrentlegalrequirements).
- Wherethereisalreadyaconnectiontoexistingueexhausts,
check that these exhausts have been perfectly cleaned
and are without residues, because any disconnection
couldobstructthepassageoffumesandcreatepotentially
dangeroussituations.
- Makesurethat,whereunsuitableueexhaustsareattached,
theyhavebeenducted.
- In areas with particularly hard water, limescale may build
upon thecomponents insidethe applianceand reduceits
overallefciency.
B11bs-type appliances are open-chamber versions
designedtobeconnectiontoauegasdischargeduct
whichreleasesfumestowardstheoutside;combustionair
istakendirectlyfrominsidetheroominwhichtheboiler
isinstalled.
Fluegasisdischargedthroughanaturaldraughtsystem.
THIS TYPE OF APPLIANCE CANNOT BE INSTALLED
IN A ROOM THAT DOES NOT MEET APPROPRIATE
VENTILATION REQUIREMENTS.
So that the normal operation of the appliance is not
compromised,theplaceinwhich itisinstalledmustbe
suitable with regard to the operating limit temperature
valueandtheapplianceshouldbeprotectedsothatitdoes
notcomeintodirectcontactwithatmosphericagents.
The appliance must be installed on a solid, non-
combustible,permanentwalltopreventaccessfromthe
rear.
When creating a space for the boiler, the minimum
distances(whichensurethatvariouspartsoftheappliance
maybeaccessedafterithasbeeninstalled)shouldbe
respected.
WARNING!!
NO INFLAMMABLE ITEMS SHOULD BE LEFT
IN THE VICINITY OF THE APPLIANCE.
MAKE SURE THE INSTALLATION SITE
AND ANY SYSTEMS TO WHICH THE
APPLIANCE MUST BE CONNECTED ARE
FULLY COMPLIANT WITH THE CURRENT
APPLICABLE LEGISLATION.
IF DUST AND/OR AGGRESSIVE VAPOURS
ARE PRESENT IN THE ROOM IN WHICH IT IS
TO BE INSTALLED, THE APPLIANCE MUST
OPERATE INDEPENDENTLY OF THE AIR
INSIDE THE ROOM.
Installation location
Observetheregulationsinforce,whendecidingwhereto
installthedevice.
Install the appliance in a PERFECTLY VERTICAL
POSITION.
Thedevicemustnotbeinstallednearheatsources.
Do not install the device in environments where
temperaturesmayreach0°C
Forinstallationinsidefurniture,considerthatthemaximum
temperatureofthedevicejacketislowerthan85°Cand
distancesrequiredformaintenancemustberespected.

thecorrectcountryandthatthegascategoryforwhich
the appliance was designed corresponds to one of the
categoriesavailableinthecountrywhereitwillbeused.
The gas supply piping must be created and measured
outincompliancewithspeciclegalrequirementsandin
accordance with the maximum power of the appliance;
youshouldalsomakesurethattheshut-offvalveisthe
rightsizeandthatitisconnectedcorrectly.
Before carrying out the installation, it is recommended
that the fuel pipes are cleaned thoroughly in order to
removeanyresidueswhichcouldpreventtheappliance
fromoperatingcorrectly.
Checkthatthesuppliedgascorrespondstothetypeof

¡IMPORTANT!
If the unit is installed in areas with the
presence of hard water (> 200 mg / l) is
necessary to install a water softener to
reduce the precipitation of limestone in
the heat exchanger.
The warranty does not cover damage
caused by the limestone.
¡IMPORTANT!
Do not activate the device without the lter.
Water connection
Theillustrationshowstheconnectionsforthewaterand
gasattachmentsoftheappliance.
Checkthatthemaximumwatermainspressuredoesnot
exceed10bar;ifitdoes,apressurereducingvalvemust
beinstalled.
Ensurethattheminimumpressureisnotlowerthan0,2

Theappliancemustbeconnectedtoauegasdischarge
system that complies with the regulation in force and
instructionsprovidedbythemanufacturer.
WHEN TYPE B INSTALLATION IS USED, THE ROOM
IN WHICH THE APPLIANCE IS INSTALLED MUST BE
VENTILATED USING A SUITABLE AIR INLET WHICH
COMPLIES WITH CURRENT LEGISLATION.
Wheninstallinganexhaustsystem,takecareoftheseals
topreventanyuegasleakingintotheaircircuit.
Make sure that the combustion products are properly
expelledbymeasuring theCO2content atthenominal
heatoutput.Thisvalueshouldnotexceedthatindicated
intheTechnicalDatatable.
Ifthevalueisgreater,checktheefciencyoftheuegas
exhaustsystem.
IfitisnotpossibletobringtheCO2valuewithinthelimit
indicated in the Technical Data table, do not start the
appliance.
ATTENTION
NEVER TAMPER WITH OR DECOMMISSION
THE FLUE GAS SENSOR. THIS COULD
AFFECT THE PROPER OPERATION OF THE
APPLIANCE.
POOR DRAUGHT CONDITIONS COULD
CAUSE EXHAUST GAS BACKFLOW INTO THE
INSTALLATION ROOM.
HAZARD OF CARBON MONOXIDE
INTOXICATION.
The part of ue pipe that pass through the wall
of dwelling should be surrounded by insulated
material (such as asbestos cloth) at least 11
mm thickness and 300 mm length since the
temperature of ue pipe maybe exceed the
ambient temperature by more than 60K.
