Some of you have offered great advice. Anyone who has followed and responded to my turbo pace posting, I greatly appreciate your help. But now I'm trying to keep my current country comfort wood insert. My problem is it is currently a direct connect setup with an oval section of ss pipe going up about 10-12 ft and dumping into a 13x13" clay flue. Now what I would really like to do is get a new stove but money is an issue. So I was thinking of dropping 25' of insulated ss liner down my chimney , capping, and putting a 6" circle to oval adapter. This would allow me to swap a new stove in down the road but allow me to have a much safer and I hope more efficient current setup . Can any of you comment on this plan and if it is worth the trouble of doing a proper 6" circle ss flexible liner down to the top of the stove and then adding an oval type adapter to fit my stoves collar? Also is splicing/coupling on to a section of ss liner a safe thing to do. Just curious of when I get a new stove will adding a section to the bottom of my liner(top of new stove) be ok to complete the 6" down in place of the oval adapter? I'm not even sure if there is a stainless adapter that goes from a 6" circle to the oval shape I need. Any insight once again is greatly appreciated.
