I’m installing an old Buck stove in a 1964 brick house. Chimney is close to center of house. Stove will be installed in the living room and will vent to the existing 6” chimney flue pictured below. Original wood paneling removed. I’ll be replacing it with a wall of durock and thin brick. But it’s the stove pipe I’m confused about.
The 6” hole in the picture has 4” clearance on either side to the 2x4. I know to make that workable, I’ll need an insulated thimble. But I can’t find any reference to what type of thimble I need for this set up, the correct sizing, how it’ll be attached behind the wall and onto the chimney. My head is spinning. Probably overthinking it, but I want this done right the first time.
