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 water heater. 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gasventor
chimneytowhichthewaterheatervent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.
Keepcombustiblessuchasboxes,magazines,clothes,etc.,away
fromthewaterheaterarea.
Installationofthewaterheatermustbeaccomplishedinsuchamanner
that if tank or any connections should leak, the ow will not cause
damagetothestructure.Forthisreason,it isnotadvisabletoinstall
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store.Such
ametaldrainpanmusthaveaminimumlengthandwidthofatleast2”
(51mm)greaterthanthewaterheaterdimensionsandmustbepiped
toanadequatedrain.Thepanmustnotrestrictcombustionairow.
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
