Theboilersshareacommonoutercasewithinwhichthereisadequatespacetofitacentral

heatingpumpusingstandardfittings.

AllappliancesaredesignedforuseonGasTypeG20(NaturalGas)only,atsupplypressure20

mb.

Eachapplianceconsistsessentiallyoftwocomponents,namely:

1.COMBUSTIONCHAMBERwithheatexchanger,burnerandcontrols.

2.OUTERCASE.

InstallationRequirements

GENERAL

TheinstallationmustbecarriedoutbyacompetentinstallerandbeinaccordancewithrelevantBS

CodesofPractice,I.E.E.Regulations,GasSafetyRegulations,BuildingRegulationsandbylaws

oftheLocalWaterUndertaking.ReferencesshouldbemadetoBS6891,BS6798,BS5440Part1

&2andBS5449.

SITING

Theseappliancesmustbefittedonasuitableoutsideorinsidewallwithdueconsiderationsofthe

openfluerequirements.

TheyshouldNOTbeinstalledinabathroom,bedroomorbedsittingroom.

Aneworexistingcupboardorcompartmentusedtoenclosetheboilermustbeconstructed

specificallyforthispurpose.

DetailsofessentialfeaturesofcupboardcompartmentdesignaregiveninBS5440:2.

CLEARANCES

Theminimumverticalareasrequiredfortheappliancesdependontheapplianceratingandits

application.Thedetailsaregiveninfig5.

DetailedrecommendationsforairsupplyaregiveninBS5440:2.

Thefollowingnotesareintendedtogivegeneralguidance.Theroominwhichtheopenflueunitis

situatedrequiresanairventwhichshouldbedirecttooutsideortoaroomwhichitselfhasanair

ventdirecttooutside.Wheretheboilerisinacompartmentwithairventsdirecttooutsidetheroom

containingthecompartmentdoesnotrequiretheprovisionsofadditionalventilation.

FLUEARRANGEMENT

The80,70OFareintendedforconnectionwith125mm(5in)fluetube.The60,50and40OFare

intendedforconnectionwith100mm(4in)fluetube.

ForfullinformationonfluesrefertoBS5440,butthegeneralrequirementsareasfollows:

1)Theflueshouldbekeptasshortandaswarmaspossible.

2)Givemaximumpossibleverticalrisefromtheappliancebeforeusinganybends(preferablyat

least600mm(24in)).Avoidtheuseofrightangledbends.

3)Terminateinanapprovedterminalpreferablyaboveridgeheightbutatleastabovetheeavesof

apitchedroof.

4)IfTwinwalltypefluetubingistobeusedtheinnertubingoftheboileradaptormustnotproject

intothedraughtdiverteroftheboiler.Aboileradaptorwhichmeetsthisrequirementisobtainable.

5)Anexistingbrickchimneyshouldbelinedwithacidandmoistureresistantmaterialssuchas

stainlesssteelflexiblefluepipe.Thisisparticularlyimportantiftheflueisabove6.5metres(20ft)

inheightandnotwhollyinternal.WHETHERORNOTTHECHIMNEYISTOBELINEDITMUST

BESWEPTTHOROUGHLYBEFORETHEINSTALLATION.

6)Whatevertypeofflueisuseditmustbeproperlysupportedandnotsimplysupportedonthe

boiler.

WATERCIRCULATIONSYSTEMS

(seepages8&9)

Theappliancesareonlysuitableforconnectiontoacisternsupplyandcanbeusedwith:

1)Pumpeddomestichotwaterandpumpedcentralheatingsystems.

2)Gravityflowdomestichotwaterandpumpedcentralheatingsystems.

(a)With28mmpipestheminimumcirculatingheadforgravitydomestichotwatershouldnotbe

lessthan1metre(3ft3in)measuredverticallyfromtheflowconnectionontheboilertotheflow

connectiononthecylinder.Atthishead,themaximumhorizontaldistancemeasuredalongtherun

ofthepipeshouldnotexceed3metres(10ft).Greaterhorizontaldistancesandsmallerpipesizes

areacceptablewithsuitablyincreasedheads.Allowancesmustbemadeforpipebendswhere

necessary.

(b)Iftheaboveconditionsarenoteasilymetthenpumpedprimariesshouldbeused.

(c)Gravityflowandreturnpipesshouldbelaidtomaximumfalltoavoidairlocks.

Thefollowingpointsareofparticularimportance:

1)THEWATERSPREADERMUSTBEFITTEDTOTHEPUMPEDRETURNCONNECTIONON

ALLSYSTEMS.

2)Theappliancesmustnotbeusedonsealedsystems.

3)Thesystemmustbedesignedtoavoidreversecirculation.

4)Thestaticheadmustnotexceed30metres(100ft)ofwater.

5)Theboilersmustonlybeusedwithanindirectcylinderwhendomestichotwaterisrequired.

6)Drainpointsshouldbefittedatthelowestpointsinthesystem.

7)Thesystemmustbedesignedsuchthatgravitycirculationintheheatingsystemdoesnottake

placewhenthepumpisnotrunning.

GASSUPPLY

ThegasconnectionislocatedatthebottomlefthandsideoftheapplianceandisRC1/2(1/2in

B.S.P.T.internal).Ensurethatthepipeworkfromthemetertotheapplianceisofadequatesize.Do

notusepipesofasmallersizethantheappliancegasconnection.

ELECTRICALSUPPLY

ExternalwiringmustbecorrectlyearthedandpolarisedandinaccordancewithI.E.E.Regulations.

Forwiringinstructionssee'ElectricalConnections'.

PREPARATION

1)AsoundandlevelfloorwhichconformstotherequirementsoftheLocalAuthoritiesandBuilding

Regulationsmustbeprovided.

2)Selectthemostsuitablepositionfortheboilertakingdueaccountofanyclearancesrequiredfor

thesafeandproperfunctionsoftheboileranditsassociatedcontrols.

3)Manoeuvretheboilerintopositionsothatthetwospacerpipsontherearofthedraughtdiverter

touchthewall.

4)Connectthewaterflowandreturnpipes(seeBoilerConnections).

5)Connectthefluepipe,makingsurethatthefluetrimisplacedinpositionbeforethefinal

connectionismade.

6)Partiallyfittheoutercase.

7)Connecttheelectricalsupply(seeElectricalConnections).

8)Completetheinstallation(seeCommissioningtheUnit).

9)Completetheassemblyoftheoutercase.

BOILERCONNECTIONS(Fig3)

Theboilershave5waterconnections:

2xRp1(1inBSPinternal)returnconnections.

2xRp1(1inBSPinternal)flowconnections.

1xRp3/4(3/4inBSPinternal)flowconnection.

The1xRp3/4(3/4inBSPinternal)flowconnectionisforusewhenthepumpisfittedinsidethe

outercase.Forotherinstallationsthisconnectionmustbeplugged.THEWATERSPREADER

MUSTBEFITTEDTOTHEPUMPEDRETURNCONNECTIONONALLINSTALLATIONS.THE

MARKSONTHESPREADERMUSTBEBETWEENTHETWOMARKERSONTHE

COMBUSTIONCHAMBER(Fig4).

Thespreaderhasonemarkonthe80,70andhastwomarksonthe60,50,40.

Wheninstallingthepipeworkensurethat:

a)Suitableunionfittingsareusedatthefirstjointofallboilerconnections.

b)Thepipeworkwillrunthroughthecutoutsprovidedintheoutercase(Fig2).

c)Drainoffpointsareprovidedasappropriate.

d)Pipesizesaresuitableforthesystemdesign.

Pump(Fig1)

Asuitablepumpe.g.GrundfosSelectric4orSMCCommodorewithballtypeisolatingvalvesand

22mmcompressionfittingsmaybefittedinsidetheoutercase.

Thepumpshouldbeconnectedtothe3/4inflowconnectiononthefrontoftheheatexchanger

usingthefollowingstandardfittings.

Theredundantflowconnection(s)mustbeplugged.

Accuracyisimportanttoavoidthepumpandorpipeworkobstructingremovalofthetoppanelof

thecombustionchamber,orfoulingthetoppaneloftheoutercase.

OUTERCASE(Fig6)

Assembletheoutercaseinthefollowingmanner:

1)LocatetheRHsidepaneloverthepegsattheRHsideofthebaseandpressdownwardsto

secure.Whenfittingthepanelsifaccessisrestrictedthecutoutsatthetopofthebackedgeofthe

panels.canbeusedtopassthecasefixingbrackets.

2)Securethepaneltothecasefixingbracketswithtwoofthesixscrewsprovided.

3)Repeat1&2withtheLHsidepanel.

4)Securethehingesofthefaciapaneltothetwosidepanelsusingtwoofthesixscrewsprovided.

5)Atthispointtheelectricalconnectionstothefaciapanelcanbemadeandtheappliancecanbe

commissioned.(See'ElectricalConnections'and'CommissioningtheAppliance').

6)Swingthefaciapanelupwardsandsecuretothesidepanelsusingthetwoscrewsretainedto

thecontrolfacia.

7)Lifttrimclearofflueconnectionontheboilerandlocatethetoppanelonthetopoftheside
