    I have a 20-22 foot high 7in square mason block chimney that I used for 5yrs with coal stove. Looking to install pellet stove, would there be any problems using this chimney, I usually do get a very good draft

    By rights you should go with a 4 inch pellet pipe and a 4 inch liner. But I think if you run a 4 inch pellet pipe and go into it with a 7 to 4 adapter it will work. If the draft isn't good you aren't out anything because you would need the pipe with the liner regardless. Be sure to clean the chimney first.
