Our stove install will include a 6” insulated liner in a masonry chimney. The connection to the stove will be a rear exit as the top will not work. I have read in some posts here people installing a tee to help with clean outs. My question is how is the tee supported behind the stove? I am trying to envision how it just “hangs” back behind th stove without much support. What am I missing here? Tks.
