Same here Whistlenut, and I installed a Biasi for a friend. It was a big step up from the Tarm he had!
I forgot chatting with you Keving last year. Glad you found a real boiler and your in the right place to get the info you need as you already know. Hey, I had a great winter, including coming back to Maine and never seeing the temp above 6* at daylight for the entire week.
Just what I needed to ease my mind about Tennessee. Now I know summer in Deer Isle is only about 7 days in July, so you better get busy on that thing before fog season sets in and rusts it completely!
