how does the manifold air vent work

It works in the same manner as a regular air vent: when there's air in the system, the internal float sits low and pulls open the air bleed valve; as the air gradually escapes and water level rises, so does the float; when float reaches top position, it mechanically closes off the air bleed valve.
