water heater.

NOTE: The cold water supply valve must be left open when
the water heater is in use.
13. To insure complete filling of the tank, allow air to exit by 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.

prevent damage to the tank and heating element, the tank must be filled
with water. Water must flow from the hot water faucet before turning
“ON” power.

or repeat Steps 2 and 3, remove element and reposition gasket.
Then repeat Steps 10 through 14.
15. Reconnect the two wires to the element and then check to make
sure the thermostat remains firmly against the surface of the tank.

SERVICE
If a condition persists or you are uncertain about the operation of the
water heater contact a service agency.
Use this guide to check a “Leaking” water heater. Many suspected
“Leakers” are not leaking tanks. Often the source of the water can be
found and corrected.
If you are not thoroughly familiar with your water heater and safety
practices, contact a qualified installer to check the water heater.
