Boiler Flooding

[Deleted User]

We are working on a two pipe system that another contractor installed, the boiler floods during warmer weather which is the problem we are trying to correct.  The steam piping comes off the top of the boiler and wraps around the basement in two loops and ties back into the boiler, no traps.These two loops have air vents at the ends.

Each radiator has a trap that is piped into a separate pipe that runs along each loop and feeds back into the same return line in the boiler room. Someone posted that this line should not have an air vent. Is that correct, I believe there is a problem with the condensate returning as the condensate line never got very warm during operation.

I see a problem, They tied the steam return and the condesate returns above the water line. They should all connect below the water line.
