Airtrol (IAS) location for a "pump to" system?

I'd like to install a B&G IAS and and airtrol tank fitting in an old school "pump to the boiler" system. I'm fine with keeping the compression tank. Just wondering what's the best location for the IAS as the B&G literature always has them between the send and the pump (pump from).

    With a compression tank you should come out of the boiler into the air separator then out to system. Pipe from IAS to the expansion tank

    With a bladder tank same thing except an air vent on the ias and I would put the expansion tank on the bottom of the ias. you want the ias in the hottest water

    @EBEBRATT-Ed Thanks! Now just need to figure out where to put the horizontal run. :)
