I just moved into a new house and will be installing a Jotul FC3B into an existing masonry fireplace. The clear opening in the existing damper is a approximately 5-1/2". I will be installing a 6" stainless steel pipe up through the chimney so I may need to flatten it out a bit so that it will pass through the opening. It would be an ovel where it passed throught the damper opening. The pipe will have the same cross sectional area. Any reason why this is not a good idea? The damper frame is embedded well into the surrounding masonry and I would like to avoid deconstruction and masonry work if possible.
Also, the kit comes with a closure plate for the top of the chimney opening but not include one to close off the damper frame. In my old house I packed the smoke chamber with thermafiber insulation and installed a custom closure panel on the damper frame to seal it off. Is this overkill? The plate on the top will prevent air infiltration...is there any benefit to having one on the frame as well? Sort of a belt and suspenders approach.
Thanks
