Arcoleader bleeding

[Willep74]

Hello!

Awesome site here. I was looking for instructions on how to bleed the air out of one of my circuits as I had tomove a baseboard for a remodeling project. I have checked all over but have not been able to find bleeding instructions that match my set up as I have no shut off at the return side and only one spigot on each circuit. The yellow handle in the picture goes to, what looks like, a purge tank. I can post additional pictures and any help is much appreciated!
Thanks!

That's an expansion tank, not a "purge tank". It needs to be filled with air, not water.

Ideally there would be a bleeder valve on the baseboards/radiators somewhere near the highest elevation on the system, which would allow you to eliminate the major quantity of air on the system, to the point where the circulation pump would be capable pushing water through those loops.

Somewhere on the system there is usually an air-vent & bubble trap/scoop to catch and purge the smaller bubbles as they pass by.

Variations on air vents:

With trap:

Without trap:

Radiation air bleeder variations:

Close up of a common type of radiation air-bleeder valve, sold at box stores:

So I found the bleeder valve at the highest point and when I opened it water came out right away. I will try to post some pictures of the valve and the bubble trap.
Thanks again for the help!

Bled the valves on all baseboards and let the air out on the circuits. Working great now. Thanks for the help!
