How to Power Purge?

Dan_G Member Posts: 32
I'm going to be swapping a section of HWBB for a steel panel radiator in my living room.

After I make the physical plumbing connections I realize that I need to purge the air from the system.

I'm not sure how to do this. My Munchkin 80M boiler does have a spigot on the outlet pipe.

I have 3 zones. I can close the supply and return valves on each pre and post circulator.
