Installing the New Water Heater (cont’d)
Filling the Water Heater
To fill the water heater with water:
1. Close the water heater drain valve by turning the han-
dle 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.
CAUTION
Never use this water heater unless it is completely full of
water. To 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.
