

16) SecurethenewManifoldPlatetotheunitusingthescrewsremovedinStep8.The

screwsneedonlytobehandtightenedandshouldnotbetightenedbyusingapower

drill.First,insertscrews1‐4fromFigure1,butdonotfullytightenthesescrews.Once

allscrewsareinserted,proceedtocompletelytightenscrews1‐4.



Note:Whentighteningthescrews,becertaintonotapplyexcessforceasthescrewsshould

turneasily.Ifextraforceisrequired,stop,removethescrewandtightenbyhandfirst.Excess

forcecanstripouttheoriginalholes.



17) AttachC‐ClampatthebottomoftheGasPipe(Figure2).Failuretodosowillcausegas



18) Connecttheconnector‐ManifoldPlate(Figure1).



19) FORNR83‐DVCANDNR83DVC(GQ‐2457WS‐FFAUS)ONLY:AttachtheO‐ring,feedback

pipe,andscrewontheGasValveasshowninFigure3.ThenattachtheRemote

Controllerwithscrew.



20) BeforereplacingtheFrontCover,theunitmustbeadjustedandtestedasdescribedin

thenextsection.



Adjustments:



1) Beforeelectricalpowerisappliedtotheunit,installaRemoteControllertotheunitifit

isnotalreadyinstalled.



2) Reconnecttheelectricalpowertotheunit.



3) Withinthefirsttenminutesofconnectingelectricalpowertotheunit,butbefore

pressingthePowerON/OFFbutton(displayshouldbeblank),holdtheupbuttononthe

RemoteControlleruntilthedisplayblinks“99”.ThiswillputtheunitintoMaintenance

Writermode.Ifthedisplaydon’tblink“99”,unplugtheunitforsixtyseconds,andtry

again.



4) AfteraccessingtheMaintenanceWritermode,usethe“up”and“down”buttonsto

changetheMaintenanceWriteritemnumberdisplay.Pressingthe“FLOWMETER

ALARMSET”buttonfor0.5secondswillchangetheitemnumbersettingfrom“ON”to

“OFF”.IfthePrioritylampisflashingwhenanitemnumberisdisplayed,thisindicatesan

“ON”settingforthatitemnumber,andifthePrioritylampisoff,theitemnumberis

“OFF”.



5) Change“FC”and“FE”fromOFFtoON.Theprioritylightshouldbeflashingonbothitem

numbersafterpressingthe“FLOWMETERALARMSET”.



6) Choosetheproperconversionsettingfromthechartandsetthe“A1”Maintenance

Writeritemnumberaccordingtothechart.



Note:DONOTchangeanyotheritem.Thiswillcauseafaultontheunit.



DesiredGasTypeA1

NaturalGasON



ON:“Priority”lightisflashing.

OFF:“Priority”lightisoff.



7) Aftersettingthe“A1”itemnumberforthedesiredgastype,pressandholdthe“up”

and“down”buttonstogetherforfivesecondstoconfirmthenewsettings.TheRemote

Controllerwillsoundandthedisplaywillgoblankwhenthesettingsareconfirmed.If

thisisnotdone,theunitwillnotputthesettingchangesintoeffect.



Note:ThesettingchangescanbecancelledbypressingthePowerON/OFFbutton

beforeconfirmingthesettings,oriftheunitisleftalonefortenminuteswithout

confirmingthesettings.Ifthedefaultsettingneedstobechangedagain,disconnectthe

electricalpowertotheunit,reconnectitandrepeatthisprocedure.



Testing:



1) Beforeturningonthegassupplytotheunit,verifythattheinletgassupplypressureis

withinthefollowingoperatingranges:



FORN‐0931M,NR111,ANDNC250SERIESONLY:

a. NaturalGasSupply:Min.5.0–Max.10.5inchesW.C.

b. PropaneSupply:Min.10.5–Max.14.0inchesW.C.



FORNR83‐DVC,NR83DVC(GQ‐2457WS‐FFAUS),ANDNR83OD(GQ‐2457WSUS)ONLY:

a. NaturalGasSupply:Min.4.0–Max.10.5inchesW.C.

b. PropaneSupply:Min.8.0–Max.14.0inchesW.C.



Note:Ifthesupplypressureishigherthanthemaximumallowablepressure,adjustthepressure

attheregulatororinstallasecondaryregulatoronthesupplylineconnectedtothewater

heater.DONOTattempttooperateheaterifgassupplypressureisnotwithinranges

specifiedabove.Highsupplypressurecandamagetheunitandpossiblycauseagasleak.

FIGURE7

FIGURE8

2) Next,verifythesupplypressureattheunit.Tocheck

thegassupplypressuretotheunit,atapisprovidedon

thegasinlet(Figure7).Makesuregassupplyisturned

offtotheunit.RemovethehexheadPhilipsscrewfrom

thetap.A9/32”nutdriverisrecommendedforthe

removalofthisscrew.Ifanutdriverisnotavailable,

aPhilipsscrewdrivercanbeused.Gentlyremovethe

screw,soasnottostripoutthescrew.



3) Connectamanometertothetapbyusingasilicone

tube.Turnongassupplytotheunitandconfirmthe

supplypressure.



4) Aftercheckingthegaspressuretotheunithasbeenconfirmed,turnoffthegassupply,

removethemanometertubeandreplacethehexheadscrew.



5) ChecktheManifoldpressurebyusingamanometer

(digitalmanometerisrecommended).Inorderto

checkthegasManifoldpressure,atapisprovided

ontheManifoldPlateinsideoftheunit(Figure8).

Thepressurecanbecheckedeitherbyremovingthe

hexheadPhilipsscrew(1)andconnectinga

manometerwithasilicontube,orbyremovingthe

1/8”NPTscrew(2)withanAllenwrenchand

connectingtheappropriatepressuregauge.Besure

tozerooutthemanometerbeforeattachingitto

thetap.







6) Turnonthegassupplytotheunit.



7) Beforeoperatingtheunit,checkforgas

leaksatthegasinletfittingandaroundthe

ManifoldPlateusingagasleakagedetector.



8) Ifnotalreadyon,pressthePower“ON/OFF”buttonsothattheunitisinstandbymode.

Theprioritylightshouldbeon.



9) Turnonseveralhotwaterfixtures(highflowrateisrequiredthroughtheunit)andallow

theunittogothroughitsstartupsequence.Itmaytakeseveralignitionattemptsin

ordertopurgeairfromthegaschambers.Ifan“11”codeappearsontheRemote

Controller,resettheunitbypressingthePowerbuttonontheRemoteControlleroff

andthenonagain.
