One pipe steam questions

Just got involved in this home with a modern Peerless steam boiler connected to a one pipe steam radiation system. Last season owner had issues with water squirting out of a radiator vent and damaging the wood floors. Beautiful home built in about 1930 era. All radiators have the original Vacuum air valves in place. Today the 20 year old Peerless boiler has a BFT&P getting its call from a 150 LWCO and #75's on both EOM's and a #75 on the vent of the BFT&P up near the floor joist. Pressuretrol is controlling fire on this system and not a vaporstat.  I have some ideas of what to do here but would like to hear from some folks with lots more experience on these one pipe systems than myself.

    Steam

    What is the pressure set at? Is the near boiler installed correctly?

    One pipe steam questions reply

    I had water squirting two occasions out of my steam radiators. What a mess. Once it was that the tankless coil inside the boiler for domestic hot water cracked and flooded the boiler. The other time it was a clogged pig tail that controls the pressure - an easy cheap fix. It took 4 technicians changing valves before they figured that one out.

    Is your photo sideways?

    If it is not then your vent is side ways.
    Cost is what you spend , value is what you get.
