4. INSTALLATION REGULATIONS

InstallationoftheproductandauxiliaryequipmentinrelationtotheheatingsystemmustcomplywithallcurrentStandardsandRegulations

andtothoseenvisionedbythelaw.

The installation and the relating to the connections of the system, the commissioning and the check of the correct functioning must

becarriedoutincompliancewiththeregulationsinforcebyauthorisedprofessionalpersonnelwiththerequisitesrequiredbythelaw,

beingnational,regional,provincialortowncouncilpresentinthecountrywithinwhichtheapplianceisinstalled,besidesthesepresent

instructions.

Installationmustbecarried outbyauthorisedpersonnelwhomustprovidethebuyerwithasystemdeclarationofconformityandwill

assumefullresponsibilityfornalinstallationandasaconsequencethecorrectfunctioningoftheinstalledproduct.

Beforeinstallingtheappliance,carryoutthefollowingchecks:

• Makesurethattheoorcansupporttheweightoftheappliance,andifitismadeofammablematerial,providesuitableinsulation

(DIMENSIONS ACCORDING TO REGIONAL REGULATIONS).

• Makesurethatthereisadequateventilationintheroomwheretheapplianceistobeinstalled,withparticularattentiontowindows

anddoorswithtightclosing(sealropes).

• Donotinstalltheapplianceinroomscontainingcollectiveventilationducts,hoodswithorwithoutextractor,typeBgasappliances,

heatpumps,orotherappliancesthat,operatingatthesametime,canputtheroomindepression(ref.UNI10683standard)

• Makesurethattheueandthepipestowhichtheappliancewillbeconnectedaresuitableforitsoperation. It is not allowed the

connection of various appliances to the same chimney.

• Thediameteroftheopeningforconnectiontothechimneymustatleastcorrespondtothediameteroftheuegaspipe.Theopening

mustbeequippedwithawallconnectionfortheinsertionoftheexhaustpipeandarosette.

• Theinstallationmustbeappropriateandhastoallowthecleaningandmaintenanceoftheproductandtheue.

Beforeinstallation,accuratelywashthepipesofthesysteminordertoremoveanyresidualsthatcouldcompromisethecorrectfunctioning

oftheappliance.

IMPORTANT:

a) Itwouldbeappropriatetoinstallanautomaticormanualairvalvetoallowtheairoutletfromtheplumbingsystem;

b) Incaseofwaterleaking,closethewatersupplyandpromptlywarntheaftersalestechnicalservice;

c) Thesystemworkingpressuremustperiodicallybechecked.

d) Ifnotusingtheboilerforalongperiodoftime,itisrecommendedthattheaftersalestechnicalserviceiscontactedtocarryoutatleast

thefollowingoperations:

•closethewatertapsofboththethermalsystemandthedomestichotwatersystem;

•emptythethermalsystemandthedomestichotwatersystemifthereisriskoffreezing.

system(seechapter4.2).

La NORDICA S.p.A. declines all responsibility for damage to things and/or persons caused by the system. In addition, it is not

responsible for any product modied without authorisation and even less for the use of non original spare parts.

thechimney.

4.1. OPEN expansion Tank system

ItisCOMPULSORYthattheOPENexpansionTanksystemisprovidedwith:

1. OPEN EXPANSION Tank:which hasa capacityof 10%of totalwater contentof thermo-productand ofthe installation.Thisis

installedatthehighestpointofthesystem,atleast2movertheradiatorthatisatthehighestlevel.

2. SAFETY PIPE:thatconnectsthroughtheshortestway,withoutdescendingorsiphoningparts,thedeliveryofthermo-productto

theuppersideofopenexpansiontank.ATTENTION:Theinsidediameterofthesupplypipewhichconnectsthethermoproductwith

theopenexpansionvesselmustbeequaltotheinternaldiameterofthesupplyjunctionpresentinthethermoproduct.Theabove

mentionedconnectionpipemustbewithoutsiphoningparts.

3. LOAD PIPE :whichconnectsthebottomofopenexpansiontankwiththereturnpipeofinstallation.Theminimumdiametermust

be¾”gas.Allthosepartsmustnohaveforanyreasonmeditateinterceptbodiesthatcouldaccidentallyexcludethemandmustbe

placedinroomswhichareprotectedfromfrost.Onthecontrary,iftheyfreeze,theboilerbodycouldbreakorevenexplode.Incase

offrostplacingitwillberighttoaddaproperpercentageofantifreezeliquidtothewaterofinstallationinordertodeletethewhole

problem.Innowaytheremustbewatercirculationintheopenexpansiontankbetweenthesafetyandloadingpipe.Thiswouldcause

thewateroxygenationandtheconsequentcorrosionofthermo-productandinstallationinaveryshorttime.

4. AUTOMATIC THERMAL DISCHARGE VALVE DSA whichisafurtherpositivesafetythatpreventstheboilingevenwhenelectric

energyismissing.Itismadebyavalvecoverlikeapressuresafetyvalvewhichdiffersfromitasitopensbyreachingapre-calibrated

temperature(normallyat94–95°C)andunloadhotwaterfromtheinstallationdelivery.Thiswillbereplacedwithasmuchcoldwater

comingfromtheopenexpansiontankloadingpipeofopentankbydrainingawaytheexcessiveheat.

5. SAFETY VALVE FROM 1,5 bar:maximumoperationpressureallowedforthesystemis1,5bar(equalto15mofthewatercolumn).

Higherpressurescancausedeformationandbreakageoftheboilerbody.

6. SAFETY DEVICESenvisionedbyRegulationsinvigour.

7. CIRCULATION PUMP:.Itwouldbebettertoinstallitonthereturninordertoavoidthatitcoulddisconnectitselfatveryhighwater

temperaturesbutcheckingthatitdoesnotdrivewaterintheopenexpansiontankotherwiseitshouldcauseacontinuouswater

oxygenationwithconsequent,fastcorrosionofboilerbody.Itmustbenottoavoidaforcedcirculationintheopenexpansiontank.

Furthermoreitmustbeelectricallyconnectedtoathermostatoraelectroniccontrolunitthatcanbepurchasedwiththethermo-

replaceasOPTIONALpart.

8. ANTI-CONDENSATION MIXING VALVE–(seechapter4.3)
