I have a couple of posts here, but otherwise pretty new to the forum.
My bro and I just bought a new Harman MKII for our 1200 sq ft. 1950s single story ranch in central MA.
I had some install questions.
First a couple of facts:
The stove is replacing a Surdiac 610 heater that came with the house, and it's going in the same place- in the hearth in the basement.
My next door neighbor who is a mason, suggested running the new pipe vertically and then bending it into the brick, by coring the brick and making a 90 degree pipe bend into that hole. He has a very similar house, and he did this with his pellet stove. It looks nice.
The current hearth pad brick extends out about 20". This platform rises about 10" off the floor. It's the same width as the whole hearth and was obviously built as part of the original with the same brick. The whole hearth almost looks like one L shaped piece. It makes a nice install platform. But if I do the coring thing, I'm sure the stove would have to come out farther for pipe elbow clearance.
The chimney runs up from the basement through the interior of the house, up through the first floor's living room, up through the attic, out the roof.
So here are my questions
1) Would you go the coring route or would you place the stove completely on the current pad where the old stove was and just pipe out the back into the hearth like before?
2) If you like the new coring route, what would you use for a hearth pad extension? Would you build one? Would it be flush height-wise with the current built-in pad or would you settle for lowering the stove towards the floor in front of the built-in pad?
3) If you prefer to go into the hearth, what kind of 6" pipe would you use? Stainless steel? Would you put a barometric damper on it? Can the barometric damper section be small "T" section, plugged in line with the horizontal exhaust pipe? Or does it need a few more bends off this main section of exhaust pipe?
Thanks for the advice!
