: Firstly, - have you made sure the pressure is kept below 2 psig, so there is time for the radiators to vent their air before they jam shut from the pressure?
: After that, it is a matter of having the vent holes large enough (larger than the ones upstairs) to vent enough air to provide equivalent heat downstairs.
: Baseboard is not as high as cast radiators, many of them not having enough height to have the vents at the same height as a standing radiator, so steam hits the vents earlier than standing radiators to shut them off. It is a tricky situation using low radiators in steam systems.

Thanks for your reply. The pressure guage
really does not show any appreciable system
pressure. It is new so I assume that it works.
The Hoffman vents with a 90 degree fitting will
not fit in the baseboard radiators. I need a
a high capacity vent that has a direct connection?
