Installing the New Water Heater (cont’d)
Filling the Water Heater
To fill the water heater with water:
1. Close the 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 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.
4. Check all new water piping for leaks. Repair as needed.
