    bleeding

    I am an HO myself, but have found it made no difference where you start, as each radiator has it's amount of trapped air already. I also found I needed to bleed them the next day, and a couple days later to be sure I got it all.

    depends on how far down you drained the system. if just minor, bleed them all out cold, and run the system. bleed an hour later with everything running and hot, and again the next day. if all the way drained, I run all zones on together for one minute, and re-bleed, twice, to get all the air out of the boiler before firing it up for any time to eliminate boiling.
