SEDIMENT TRAPS
Asedimenttrapshouldbeinstalledasclosetotheinletofthewater
heater as practical at the time of water heater installation. The
sedimenttrapshouldbeeitherateettingwithacappednipple
in the bottom outlet or other device recognized as an effective
sediment trap. If a tee tting  is used, it should be installed in
conformance with one of the methods of installation shown in
Figures12and13.
Contaminantsinthegaslinesmaycauseimproperoperationofthe

FILLING THE WATER HEATER
Neverusethiswaterheaterunlessitiscompletelyfullofwater.Toprevent
damagetothetank,thetankmustbelledwithwater.Watermustow
fromthehotwaterfaucetbeforeturning“ON”gastothewaterheater.
Tollthewaterheaterwithwater:
1. Closethewaterheaterdrainvalvebyturningthehandletotheright
(clockwise).Thedrainvalveisonthelowerfrontofthewaterheater.
2. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open when
the water heater is in use.
3. Toinsurecompletellingofthetank,allowairtoexitbyopeningthe
nearesthotwaterfaucet.Allowwatertorununtilaconstantowis
obtained.Thiswillletairoutofthewaterheaterandthepiping.
4. Checkallwaterpipingandconnectionsforleaks.Repairasneeded.
