freezing temperatures. Also, periodic draining and cleaning of
sediment from the tank may be necessary.

water heater.

adequate drain or external to the building.
5. Open the water heater drain valve and allow all of the water
to drain from the tank. Flush the tank with water as needed
to remove sediment.
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.
6. Close the drain valve, refi ll the tank, and restart the heater as
directed in this manual.
