Thank you for asking your question on Just Answer. Turning on the hot water fixture the farthest away from the hot water heater will in most cases clear any air from the hot water system.to drain all the water lines in your home, turn off water at the main cutoff. Then fully open the lowest faucet on the system to all the water in the pipes. Open a few of the highest faucets next. When the lowest faucet stops dripping, close all faucets. Turn the water back on. When you turn on the faucets for the first time there will be some vigorous spitting until the pipes are flushed of air. If water hammering becomes a problem you might want to consider installing a water hammer arrester. Click here for more information.

Ed is off line at the moment so I will answer for him if that is alright with you.
You are correct. The answer is directed to a regular water system and not a steam heating system.

Ok the cause of waterhammering is usually excess air in your system.
To get this air out you need to bleed the system. There should be bleed valves on your heater units. Start with the lowest one (closest to the bottom of the system) and bleed off any air. Once you get water only from that one go to the next one in height and bleed the air from it. Continue till all have been bled with the highest one last.
This should take care of the problem. If it does not then you have bigger problems, and at that point you will require the services of a plumber.
The information I provided in the fist answer is applicable to both the hot and cold water lines. Water hammer most often occurs when a valve shuts off suddenly. Not when the water is turned on. Are you sure the problem is air in the lines? Often this can be caused by a defective fixture. Often noise coming from a gas water heaters is caused by the sediment build up in the bottom of the water heater. When the burners heat the bottom of the tank gas bubbles form under the sediment it will make a thumping and popping noises. Make sure your temperature-pressure (TP) relief valve is working since thermo expansion can cause the problem. Click here for more information on water heater noises. A broken or loose anode rod in the water heater can cause knocking and other noises, as can a broken fill tube. If your have less hot water that you normally have, check for a defective fill tube in the water heater.
