venting ModCon boiler, chimney removal


can someone tell me if it’s code violation to takedown/remove interior masonry of existing/non used chimneys within my attached brick townhouse?
would like to vent new boiler (mod/con) to roof with PVC behind chase wall, remove the brick footprint of the chimney and have a square room. I would re-brick the exposed area to match flush with the existing wall. any code problems with this?
thanks
