How to bleed a boiler with zone valves?

If you have zone valves, they can be used to bleed a boiler. The first step is to turn off all of the zones so that only one part of your house is getting hot water. Next, open up each individual zone valve and allow it to drain until no more air bubbles come out. Once all of the air has been removed from your system and there are no more bubbles coming out of any faucets or shower heads, close down each individual zone valve again before turning on hot water throughout the entire house again by opening up all of them at once (this will let steam escape).

To bleed a boiler, you need to disconnect the fuel line from the main body of the boiler and turn on its gas valve.

Once this is done, turn on your burner(s) and allow them to burn for 30 seconds before shutting them off again by closing all valves except for one–the one leading into your boiler’s tank or cylinder.

Now that all air has been expelled from inside these pipes, replace them back onto their original locations and tighten any loose connections with pliers or wrenches.
