III Before Installing
1) Safe,reliableoperationofthisboilerdependsuponinstallationbyaprofessionalheatingcontractorinstrict
accordancewiththismanualandtheauthorityhavingjurisdiction.
• Intheabsenceofanauthorityhavingjurisdiction,installationmustbeinaccordancewiththismanualand
theNational Fuel Gas Code, ANSI Z223.1.
• Whererequiredbytheauthorityhavingjurisdiction,thisinstallationmustconformtotheStandard for
Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).
2) CHGboilersutilizealuminumheatexchangersconstructed,tested,andstampedinaccordancewithASME
BoilerandPressureVesselCodeCase2382-2.SomejurisdictionswhichrequireASMEboilerconstruction
donotrecognizethisCodeCaseandmaynotapprovetheinstallationofanaluminumboiler.Consultthe
authorityhavingjurisdictionbeforeinstallingthisboiler.
3) ReadSectionVItoverifythatthemaximumcombustionairandexhaustpipelengthswillnotbeexceededin
theplannedinstallation.Alsoverifythattheventterminalisinstalledintheproperlocation.
4) Makesurethattheboileriscorrectlysized:
• Forheatingsystemsemployingconvectionradiation(baseboardorradiators),useanindustryaccepted
sizingmethodsuchastheI=B=R Heat Loss Calculation Guide(Pub.#H21or#H22)publishedbythe
HydronicsInstituteinBerkeleyHeights,NJ.
• Fornewradiantheatingsystems,refertotheradianttubingmanufacturer’sboilersizingguidelines.
• ForsystemsincludinganAlliance™indirectwaterheater,sizetheboilertohaveeithertheDOEHeating
CapacityrequiredfortheAlliance™orthenetratingrequiredfortheheatingsystem,whicheverresultsin
thelargerboiler.
• Forsystemsthatincorporateotherindirectwaterheaters,refertotheindirectwaterheatermanufacturer’s
instructionsfor��boileroutputrequirements.
5) Makesurethattheboilerreceivedisconguredforthecorrectgas(naturalorLP).
6) Makesurethattheboilerisconguredforuseatthealtitudeatwhichitistobeinstalled.
IV Locating the Boiler
1) ObservetheminimumclearancesshowninFigure4.1.Theseclearancesapplytobothcombustibleandnon-
combustiblematerials.ObservetheminimumclearancestocombustiblesforventpipeshowninTable4.2.
2) NotetherecommendedserviceclearancesinFigure4.1.Therecommendedserviceclearancesmaybe
reducedtotheminimumcombustibleclearanceswiththeunderstandingthatservicingtheboilerwillbecome
increasinglydifcultastheclearanceisreduced.
3) Boilermaybeinstalledonnon-carpetedcombustiblesurface.
4) Thereliefvalvemustbeinstalledinthefactoryspeciedlocation.
5) Theboilershouldbelocatedsoastominimizethelengthoftheventsystem.
6) Thecombustionairpipingmustterminatewhereoutdoorairisavailableforcombustionandawayfromareas
thatwillcontaminatecombustionair.Avoidareasnearchemicalproductscontainingchlorine,chloridebased
salts,chloro/uorocarbons,paintremovers,cleaningsolventsanddetergents.
