Thewaterheatercannotperformproperlywithoutsufficientinletgaspressure.Belowareinstructions
onhowtochecktheinletgaspressure.THISISONLYTOBEDONEBYALICENSEDPROFESSIONAL.

1. Shutoffthemanualgasvalveonthesupplygasline.
2. Removethescrewforthe

diagramtotheright.
3. Connectthemanometertothepressureport.
4. Re‐openthemanualgasvalve.Checktoseethat
therearenogasleaks.Opensomeofthefixtures
thatusethehighest
flowratetoturnonthewater
heater.
5. Checktheinletgaspressure.Whenthewaterheater
isonmaximumburn,themanometershouldread
from5.0”to10.5”WCforNaturalgas,from8.0”to
