    Exclamation Air release ? in a converted gravity system

    First off, forgive me if my terminology is off.

    OK, I had an original "gravity" boiler system. The old expansion tank was way up in the attic. The tank/leftover pipes are higher than any radiator. I'm concerned about the air trapped in these pipes without a radiator to bleed. Do I simply insert an air release valve like the Taco slimeline hy-vent model below. Please see diagrams.

    OLD SETUP



    NEW SETUP??

    good question.. because you will never get the air out of the lines above the highest air vent in your system I am betting.

    I'm now almost certain I need to connect the pipes (based on the first picture above) it's a supply and return piping through the tank.

    Still, how do I remove this air in the pipes above the highest radiator (1 floor below)????

    1) Just connect the pipes

    2) Connect the pipes and add an air release in between them
