AA130 DIY Install

It really is a no brainer if you have basic plumbing and electrical skills. Traditionally, many AA boile3rs were installed by coal dealers, not plumbers.

I recommend primary-secondary piping. each boiler should be piped separated into the system.

Use copper if you can.

Mike is correct. Mass. requires a permit if you're doing anything with your domestic supply and/or doing anything with respect to connecting to the public supply. Among other things, they want to make sure check valves are installed to ensure that nothing can back up into the domestic/public supply. So a permit is required and only a licensed plumber can pull that permit.

You also need a building permit that seems to be only concerned with the stack connection. At least that was all they were concerned about in my case.

If you do it "by the book" in Mass. be aware that they most likely won't let you connect both systems to the same flue. Very unlikely any city/town inspector will let this slide. I did do my own electrical with no issues. Really strange thing was that the fire department (fire prevention) doesn't need to check things. I believe they do for oil (maybe because it can spill?).

All of this assumes that you plan to pull permits. You probably won't be able to just do the building permit. The building inspector is supposed to require the plumbing be signed off on first. His is the last signature - then you can light things up.

I'm the guy in Leominster with the AA-130 that JBSparks referred to. You're welcome to take a look some time. (Send a PM if interested.) I can tell you for sure that knowing what I know now I would have do the plumbing differently were I to do it again. (And I might do that come warm weather.)

Good luck,
