View Full Version : Homeowner Boiler installation

I would like to participate in the installation of a gas-fired mod/con boiler in my home, which is in Boston. However, it's my understanding that in Massachusetts a gas-fired boiler can only be installed by a licensed plumber or gas fitter.

My question is how "installed" is defined.

First, I would never attempt to install the gas line, attach that line to the boiler, or commission the boiler (ie start it up). This would likely be illegal but in any case requires skills and/or equipment that I do not possess.

However, I can sweat copper beautifully and enjoy doing so. Furthermore, can read the installation manual and follow it's directives. In addition, I believe I understand how the equipment I wish to install operates. Finally, I've done a significant amount of modification to my current heating system which has been very successful (I have oil-fired steam and I've added 3 hot water zones piped from the condensate, indirect fired DHW piped from the condensate and several radiant floor zones run off a tankless coil). The point is that this would not be my first project.

So, could I legally assemble the near boiler piping, perhaps leaving unions to facilitate the final "installation" of the boiler, then leave it up to a plumber to attach the device, install gas lines, fire it up and verify proper installation?

I've tried getting in touch with the plumbing inspector for my town but they haven't as yet return any of my calls.

Thanks - DP

Because state and local codes vary, you would be best served by consulting with an authority in your area.

If I could get local building authorities to respond to my question I would. I've contacted one local plumber/gas fitters but he was not enthusiastic about working with me. Nor did he provide a direct answer to my question.

Although your comments do not speak to the question I asked, the gas service to my house is only a few years old - new valve and plastic line up from the street. I delayed installing any gas appliance and the meter has not yet been hung. Thus, there is not reason to think there would be any problem with pressure. In any case, as I stated initially, the gas piping is something a licenced plumber/gas fitter will do, and be responsible for, not me.
