Boiler setup

Ian Daniel

Hello all I am just a handyman but boilers are my hobby, so forgive me if I do not have the proper terminology. A tenant for one of the properties I maintain complained last winter of banging in the steam system and water coming out of the relief valves. It was a new system last year and apparently they had some trouble installing it. I went and looked at the system and then referred to the Lost Art Of Steam Heating and this is what I think is wrong: When the pipe comes out of the boiler (manifold) it goes directly into a T one side going to the cold water return and the otherto the system and then a few inches later into a ninety and then up to the system. From what I understand you need a place to make steam in these new high E boilers and that is why you need the manifold to rise up before you T the cold water return and then rise a little further before you T to the system.
Is this correct? Thanks for any feed back
