FACTS TO CONSIDER ABOUT THE LOCATION
Carefullychooseanindoorlocationforthenewwaterheater,because
theplacementisaveryimportantconsiderationforthesafetyofthe
occupantsinthebuildingandforthemosteconomicaluseofthe
appliance. This water heater is not for use in manufactured
(mobile) homes or outdoor installation.
Whetherreplacinganoldwaterheaterorputtingthewaterheaterin
anewlocation,thefollowingcriticalpointsmustbeobserved:
1.Selectalocationindoorsascloseaspracticaltotheventterminalor
locationtowhichthewaterheaterventpipingisgoingtobeconnected,
andascentralizedwiththewaterpipingsystemaspossible.
2.Selectedlocationmustprovideadequateclearancesforservicing
andproperoperationofthewaterheater.
Installationofthewaterheatermustbeaccomplishedinsuchamanner
thatifthetankoranyconnectionsshouldleak,theowwillnotcause
damagetothestructure.Forthisreason,itisnotadvisabletoinstall
thewaterheaterinanatticorupperoor.Whensuchlocationscannot
beavoided,asuitablemetaldrainpanshouldbeinstalledunderthe
waterheater.Metaldrainpansareavailableatyourlocalhardware

(2.5cm)greaterthananypointonthewaterheater’souterjacket
andmustbepipedtoanadequatedrain.Thepanmustnotrestrict
combustionairow.Forexample,ifacircularpanisused,itmust
beaminimumof27”(69cm)indiameter.SeeFigure1.
