How do I properly bleed a baseboard system that has no bleed valves?

Hello -- I've got a baseboard heating system with and older American Standard GPH-80 boiler. I just replaced the expansion tank and had to drain the system to do it. I'm in a 2 story house; the boiler is in the basement. Well, needless to say, the previous owner neglected to install bleed valves anywhere in the system except right next to the pressure relief above the boiler.

I do have a drain on the boiler and a drain on each of the pipes that split off after the expansion tank.

Any recommendations on how to get all of the air out of this system?

Brian, can you post pics of the system on a free account at Image hosting, free photo sharing & video sharing at Photobucket ? provide a link here to the pics ... it will help us help you ... much easier to tell you which valve to turn, etc ...

I hope you put a valve between the expansion tank and the air scoop ? Sure makes it easier to change a tank out ... not having to drain the system and all ...
