1.Setthepowerswitchtothe“OFF”position.
2. CLOSE the cold water inlet valve to the water heater.
3.OPENa nearby hot water faucet and leave open to allow for

5.OPENthewaterheaterdrainvalvetoallowfortankdraining.
note: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
