GENERAL OPERATION
TO FILL THE WATER HEATER
1. Close the water heater drain valve by turning the stem clockwise.
2. Open the cold water supply shut-off valve.
3. Open several hot water faucets to allow air to escape from the system.

filled. Close the faucets and check for water leaks at the water heater drain
valve, combination temperature and pressure relief valve and the hot and
cold water connections.
