2. Allgaswaterheatersrequirecarefulandcorrectinstallationto
ensuresafeandefficientoperation.
Thismanualmustbefollowedexactly.Readthe“SafetyGuidelines”sectionintheinstallation
manual.

3. Themanifoldgaspressureispresetatthefactory.Itiscomputercontrolledandshouldnotneed
adjustment.

4. Maintainproperspaceforservicing.Installtheunitso
thatitcanbeconnectedorremovedeasily.
RefertotheClearancesSectiononp.8oftheinstallationmanualforproperclearances.


5. Thewaterheatermustbeinstalledinalocationwheretheproperamountofcombustibleairwill
beavailabletoitatalltimeswithoutobstructions.

6. Theelectricalconnectionrequiresameansofdisconnection,toterminatepowertothewater
heaterforservicingandsafetypurposes.


7. Donotinstalltheunitwheretheexhaustventispointingintoanyopeninginabuildingorwhere
thenoisemaydisturbyourneighbors.Makesuretheventterminationmeetstherequireddistance
bylocalcodefromanydoorwayoropeningtopreventexhaustfromenteringabuilding.

8. Particlesfromflour,aerosols,andothercontaminantsmayclogtheairventorreducethefunctions
oftherotatingfanandcauseimproperburningofthegas.Regularlyensurethattheareaaround
theunitisdust‐ordebris‐free;regularmaintenanceisrecommendedforthesetypesof
environment.

9. Ifyouwillbeinstallingthewaterheaterinacontaminatedareawithahighlevelofdust,sand,

10. Direct‐ventconversion:
• Theseunitsmaybeconvertedtoadirect‐vent(sealedcombustion)appliancebyinstallinga
direct‐vent conversion kit (Part No. 9007669005) which will bring in all required
combustibleairfromoutsidethebuilding.Wheninstallingtheconversionkit,pleasefollow
allinstructionsincludedwiththe
kit.
• Ifthewaterheaterisusedasadirect‐ventappliance,theunitrequiresa5”intakeairpipe.
The intake pipe must be sealed airtight.  Air supply pipe can be made of ABS, PVC,
galvanized steel, corrugated aluminum, corrugated stainless steel or Category III stainless
steel.
•
Terminatingtheventingthroughasidewallisrecommendedforthedirect‐ventsystem.
• Runningtheexhaustventandtheintakepipeparallelisrecommended.
• Terminating the e xhaust  and intake on the same wall  / surface is recommended.
Terminating in the same pressure zone allows for pressure balancing, which prevents

nuisance shutdowns.Be sure to allow for proper clearance between the exhaust and
intake.
