Getting 4gpm run residential baseboard heating air out of system

in Radiant Heating
What’s the best way to get air out of 3/4” baseboard radiant heating system if it runs on a 4gpm recirculating pump? My understanding is that the velocity won’t be able to push the air out of the system on its own right? So I would need to install manual vents on each radiator right? What would be the best approach? Thanks in advance

    If piped right you should have no air.
    With baseboard, some properly placed components and you usually just purge it at the boiler.

    There was an error rendering this rich post.

    Depends on your pipe size. If it's 3/4" and piped in a loop you shouldn't have an issue. If it's monoflow or something else you could have an issue. With a series loop you can bleed at each baseboard or at a purge valve. Once you get water moving 4gpm in 3/4 pipe will move any remaining air back to the boiler
