I have a one pipe steam system with to burnham boilers about 7 years old one for the first floor one for the second floor it used to be a 2 family . There is only one vent on each main both on the elbow right before the drop the tappings are only 1/8 I no there in the wrong place and the tappings are to small but I was told if I used gorton # d that it would be fine any thoughts Thanks

    This is what I had my neighbor do.
    He used my four heatimer varivalves as main vents, two per main.

    I'd try to mount them high enough and away from anything that could be damaged by water. Also, keep an eye on them from time to time as they are known to fail shut.

    How long are the steam mains, and what diameter?

    When the spring has arrived, and you can shut down the boiler, make whatever modifications are necessary, and enlarge those vent opennings, and put at least one Gorton #2 in each. Adequate venting will shorten the time for steam to get to the radiators, and will shave several minutes off each burn time, ($$$$$$$$$)
    Keep the pressure low.--NBC
