I need some advice getting my chimney lined and capped. Per my thread on choosing a stove, I plan on having Jotul F45 or Hearthstone Craftsbury professionally installed by the dealer. However the chimney needs to have the top courses reset, and the dealer is not a mason, so I need to solve that first.
Do I need an insulated liner?
Should I use an oval rectangular liner? I have talked to 3 sweeps they mention they can "ovalize" a 6" liner, effectively by stepping on it. Seems like ordering the correct part would be a better plan. If so, what size oval / square meets 6" round?
I was planning on a new stainless multi-flue cap and flex liner because it looks like there is an offset at the bottom.
One person I talked to said something along the lines of "because your old chimney is internal to the house, and does not have 2" spacing to combustibles, to meet code I would have to pour some loose cement inside the chimney to provide another barrier between the metal liner and the clay liner". I think this is a "cast in place" liner? That doesn't seem right for a chimney with steel liner + clay liner already in place.
- The chimney is 100 years old, and inside the house. It is clay lined and appears to be in good shape. 2 Flues (the second is unused and goes into basement)
- The stoves require a 6" liner, and the flue inner dimensions are 7" x 15".
- The mason is going to rework the firebox to raise the lintel and open the smoke shelf gap for the liner, and fix the chimney top and cap it. He offered to install the liner, and I think I'd prefer so he can make sure everything is ready to go when the stove arrives.
