Flue stop question

[Dejvan]

We’ll have freestanding stove with kinda like situation on the picture. We are most likely goning to have new thimble hole made higher on the brick wall into the chimney to accommodate the new stove. There will be all new stainless steel liner and components connecting to a new stove.
My question is…can I simply plug the old lower thimble with this $10 flue stop, maybe add some caulk for seal and be done? Thanks in advance

Yes, if the new thimble and liner are directly connected to the new stove, then the old hole is just a hole. It can be capped or bricked in, or...
have the bottom of the liner tee (that connects thru the new thimble extended to a second, lower tee the aligns with the old thimble hole. The bottom of the lower tee gets capped, with a removable cap on the snout that passes through the old thimble hole. This lower connection now serves as a cleanout port for easy cleaning of the liner.

Thank you, we have a cleanout on the outside of the chimney, so most likely with the pipe going all the way down from tee…that will stay cleanout. Also we want the new stove to go as close to the wall as possible so it will also block the olde thimble

That will work too. Just be sure the lower end or the liner at the cleanout is capped. The cap gets removed at cleaning only.
