Make the hot and cold connection, open the hot side of a faucet and turn the water on. As the tank fills, the air will come out the faucet until the tank is full.

What is the anode in a gas water heater?

The sacrificial anode in a Hot Water Tank takes most of the rusting problems away from the tank itself, hence the word "sacrificial!" When the anode has finished its course of use, you will get rusting happening on the walls of your tank which leads to a wrecked and leaking hot water tank. Manufacturers do NOT want home owners to know about these anodes, because if everyone replaced them there would not be any hot water tanks to replace.
