I have an older farm house that has a masonry chimney. I had a stainless steel 6 inch flexible liner installed due to the age of the chimney. It has a fixed center thimble height of 28-1/2 ". I have an older Nordic stove (very similar to the Jøtul F 118 CB Black Bear ) that has become leaky. I rebuilt it about five years ago but never could get it tight to prevent smoking. I want to purchase a new stove, but need rear vent that will be the same height. Any suggestions on a stove with that height rear vent? Don't want to spend a fortune either!
