Vented?
Meaning there is a tank at or above the highest radiator and the tank
has an open top? If that is what you have the tank water level has
to be
above the highest radiator.

The boiler has a vent/filler tube on top, with a rain cover. It
passes air freely.

Where is the boiler? On the roof? Higher than the highest radiator?

Outside in the yard. Lower than the lowest radiator.

Well no fricken wonder the vent sucked air in. Better call the place
that installed it.

I don't see how the system will stay reliable. Most of the system
operates under a vacuum. I expect that over time you will accumulate air
in the radiators. You can't bleed any radiators (air will go in).
