Gas fired steam boiler startup water loss problem
I've been reading heating help for a few months now, but this is my first outcry for help.
This is my story; I bought a 2 floor house in Somerville, Massachusetts and converted from oil fired system to gas fired system. Ever since the system has been installed, i've been having problems. The water in my boiler leaves the system way too fast (it seems more like they are being drained upward into my main pipes). within few minutes of the boiler turning on, the water is completely gone into the pipes; resulting in wet steam, gurgling/boiler sound, and massive pipe hammering.
Event though there are two boiler raiser connections, the plumber only installed one (manufacturer document specifies the second raiser is optional).
The distinct between the normal water level and the header (it's the pipe connects to boiler raiser?) is 25 inches (manufacturer installation requires 24").
Isn't the header suppose to tilt down toward the return pipes (hartford loop?) instead of tilt up toward the return?
The original system did not come with main vents or connections. I added an antler with 2 gordon #1 vents to the end of the dry return pipe (18 inches away from the drop to wet return); few minutes after the system's turned on, water comes out of the gordon #1s as if they are faucets (i am guess its caused by the fact water leaves my boilers too fast).
I think maybe adding another 2" boiler raise will decrease the velocity of steam leaving the boiler, resulting in dry steam leaving the boiler?
I have a burnham PIN5SNI-ME2.
