Hi: I have a free standing propane heat stove that's vented through a conventional block chimney. I noticed while cleaning it that it has a three inch flexible sleeve running through it from top to bottom . I'd like to replace the stove with a wood burning one. Would I have to remove the sleeve? run a stove pipe?
