• 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.

when the water heater is in use.

opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of the
water heater and the piping.

ment, the tank must be filled with water. Water must I
flow from the hot water faucet before turning "ON"
