High voltage connections
The connection to the mains supply must be made via a separation device
with an omnipolar opening of at least 3.5 mm (EN 60335/1 - category 3). The
applianceworkswithalternatingcurrentat230Volt/50Hz,andisincompliance
with Standard EN 60335-1. It is obligatory to make the connection with a safe
ground/earth,incompliancewithcurrentdirectives.
b
The installer is responsible for ensuring the appliance is suitably earthed;
the manufacturer will not be liable for any damage resulting from an in-
correct or absent earth connection.
b
It is also advisable to respect the phase-neutral connection (L-N).
b
The earth conductor must be a couple of cm longer than the others.
b
To create the seal of the boiler use a clamp and tighten it on the cable
grommet used.
The boiler can operate with a phase-neutral or phase-phase power supply. It
is forbidden to use gas and/or water pipes to earth electrical appliances. Use
the power cable supplied to connect the boiler to the mains power supply. If the
powercablehastobereplaced,useaHARH05V2V2-F,3x0.75mm²cable,
Ø max external 7 mm.
2.5 Gas connection
The connection of the gas supply must be carried out in compliance with current
installationstandards.Beforecarryingouttheconnection,checkthatthetypeof
gas is that for which the appliance is set up .
2.6 Removing the casing
Toaccessthecomponentsinside,removethecasingasshowninthegure.
b
Ifremovingthesidepanels,putthembackintheirinitialposition,referring
to the adhesive label on its wall .
b
If the front panel is damaged it must be replaced .
b
The noise absorbing panels inside the front and side walls ensure the
airtight seal for the air supply duct in the installation environment .
b
It is therefore CRUCIAL after the dismantling operations to correctly re-
positionthecomponentstoensuretheboiler’ssealise󰀨ective .

withlocalstandardsoftheFireDepartment,theGasCompanyandwithpossi-
ble municipal dispositions.
Itisessentialfortheevacuationoftheuegasesandtheadductionoftheboi-
ler’s combustion air that only original pipes be used (except C6) and that the
connectionismadecorrectlyasshownintheinstructionsprovidedwiththeue
gases accessories .

vingfromtheuegasdischargesystemusingitsownsiphon .
b
If a condensate relaunch pump is installed, check the technical data
(providedbythemanufacturer)regardingoutput,toensureitoperates
correctly .
- Positionthedischargepipesothattheconnectionsitsfullyupagainsttheue
gases turret of the boiler.
- Afterpositioningit,makesurethe4notches(A) slip into the groove (B).
- Fully tighten the screws (C)thatholdthetwoangelockingterminals,sothe
