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drainpanshouldbeinstalledunderthewater
heater.Drainpansareavailableatyourlocalhardwarestore.Such
adrainpanmusthaveaclearanceofatleast1.0”(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.
Waterheaterlifedependsuponwaterquality,waterpressureand
the environment in which the water heater is installed. Water heaters
aresometimesinstalledinlocationswhereleakagemayresultin
propertydamage,evenwiththeuseofadrainpanpipedtoadrain.
However,unanticipateddamagecanbereducedorpreventedby
aleakdetectororwatershut-offdeviceusedinconjunctionwitha
pipeddrainpan.Thesedevicesareavailablefromsomeplumbing
supplywholesalersandretailers,anddetectandreacttoleakage
in various ways:
• Sensorsmountedinthedrainpanthattriggeranalarmorturnoffthe
incomingwatertothewaterheaterwhenleakageisdetected.
• Sensorsmountedinthedrainpanthatturnoffthewatersupplyto
theentirebuildingwhenwaterisdetectedinthedrainpan.
• Watersupply shut-offdevices that activate based on the water
pressuredifferentialbetweenthecoldwaterandhotwaterpipes
connected to the water heater.
• Devicesthatwillturnoffthegassupplytoagaswaterheaterwhile

INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED
(GARAGES,STORAGEANDUTILITYAREAS,ETC.):Flammable
liquids(suchasgasoline,solvents,propane(LPorbutane,etc.)and
