I have a masonry chimney that is being relined with 6" stainless and poured insulation in the cavity between the liner and clay flue tiles. I have security double wall pipe that I am planning on using on the inside and will need one 45 section and 12" section to complete. I'm not sure what I will need to connect to the 6" stainless T stub at the wall. Can you advise what I might need?

Answer:The connection to the stainless liner tee can be made to the Security double wall piping by simply crimping the end of the tee stub with a 5 bladed crimper, then pushing it into the inner wall of the Security stovepipe. Security makes a flue adapter for masonry applications with an unlined chimney, but the adapter will not work with a liner and tee.
