Location of auto. air vent in hot water\baseborad system?

Hi Folks,
I have a 3 zone hot water\baseboard heating system in my rancher. I have had problems with air in the baseboard heaters.
I would like to install some auto air vents to help eliminate these air problems - as currently there are none.

Therefore, where should they be located? Do I need to install one for each zone? At the start or end of the zone loop?

Or can I just install one auto air vent on the boiler? I was told that I could just install just just prior to the pressure relief valve? (tee off the line between the boiler and the pressure relief valve and then install the air vent here) I guess the logic is that it would remove the air from the boiler tank?

Thanks in advance for your help!

Auto vent(s)

If you can host some pix of the boiler & near boiler piping it would be a great help.
