How does the damper seal against uneven stone?
Seriously, there's brick inside the chimney but it too is not even..I need to seal the somehow.[/quote]
Make a cardboard template about 3/8 to 1/2" smaller to fit,then hammer drill 3/8" holes under the template and install bolts long enough to hold up the template. Make your metal damper from the template,when you install the metal damper you can use refactory cement or masonry cement to seal up the gaps at the stone/brick edges.On the metal damper weld a collar on the bottom of the plate the size of your stove pipe and screw the stove pipe to it. No stove pipe is needed above the damper.
