Small Flue

[Will44]

Hi,
We have a Morso 2B Classic which we are trying to install in an old house which has a continuous vertical flue, roughly 23 feet in height, and has
a clearance of 6 3/8" square. The stove requires 6" pipe and I was going to use 6" stainless steel flex pipe to feed down the flue from the top. However, I hear that it is best to have this insulated, which pushes it over the size limits which will fit inside the existing flue. There was a woodstove previously in this flue, but was converted to gas flex pipe and now we are putting it back to wood heat. Any suggestions or ideas? Thanks

Assuming what you have is a clay liner in a masonry chimney-Best thing would be for the existing clay to be broken out and removed to make space for the new insulated stainless liner. An experienced chimney sweep should be able to do this. Make sure they clean the remaining brick chase for any buildup that may be there.
