9) AssemblyoftheAirIntakeSystemandAirIntakeTerminals:
a)AssembletheairintakesystemusingeithergalvanizedorPVCpipe.
b) IfPVCpipingisused,usePVCcementtoassemblethePVCintakesystemcomponents.

d)3”galvanizedsmokepipewilltinsidetheinletcollarontheboiler.DependingupontheexactODofthepipeused,
itmaybenecessarytocrimpthispipe.Securewithasingle#10sheetmetalscrewthroughtheholeintheinletcollar
andsealtheoutsideofthejointwithsilicone.IfPVCisusedfortheintakesystem,useashortpieceof3”galvanized
pipetoconnectthePVCtotheboiler.SiliconetheoutsideofthejointbetweenthePVCandgalvanizedpipe.
e)Horizontalintaketerminalisa90degreeelbowpointingdown.Elbowshouldprotrudethesamedistancefromthe
wallastheexhaustterminal.
f) Verticalairintaketerminalconsistsofa180degreebend(composedoftwo90degreeelbows)asshowninFigure
7.10.

F. Condensate Trap and Drain Line
 Allcondensatewhichformsintheboilerorventsystemcollectsinthesumpundertheheatexchangerandleavesthe
boilerthroughthecondensatetrap.Thistrapallowscondensatetodrainfromthesumpwhileretaininguegasesintheboiler.
ThetrapissuppliedlooseandmustbeinstalledasshowninFigure7.51.Alengthofdrainhoseissuppliedwiththeboiler
andisconnectedtothetrapasshowninFigure7.51.Notethefollowingwhendisposingofthecondensate:
a)Ifthecondensatedrainlinemustbeextended,constructtheextensionfromPVCorCPVCpipe.Insertthehose
providedwiththeboilerintotheendoftheextensionasshowninFigure7.51.
b) Condensateisslightlyacidic.Donotusemetallicpipeorttingsinthecondensatedrainline.Donotroutethedrain
linethroughareasthatcouldbedamagedbyleakingcondensate.
c)Somejurisdictionsmayrequirethatthecondensatebeneutralizedbeforebeingdisposedof.Disposeofcondensatein
accordancewithlocalcodes.
d)Donotroute,orterminate,thecondensatedrainlineinareassubjectedtofreezingtemperatures.
e)Ifthepointofcondensatedisposalisabovethetrap,itwillbenecessarytouseacondensatepumptomovethe
condensatetothedrain.Insuchcases,selectacondensatepumpthatisapprovedforusewithcondensingfurnaces.If
overowfromthispumpwouldresultinpropertydamage,selectapumpwithanoverowswitchandusethisswitch
toshutdowntheboiler.Alternatively,ifheatisanecessity,usetheoverowswitchtotriggeranalarm.
f) DonotattempttomovethetrapfromthelocationshowninFigure7.51.Donotattempttosubstituteanothertrapfor
theoneprovidedwiththeboiler.
g)TheventshowninFigure7.51mustbeleftopenforthetraptoworkproperly.
