Has anyone has success getting the DuraLiner double wall insulated 6 inch pipe down a 8 x 8 clay liner? Is it a common practice or just to tight? The literature indicates it needs 7 inches which a 8 x 8 clay liner would have but the mortar joints may make it less in some spots Im sure.
I have a 8 x 8 clay liner that is in good shape but the chimney does not have zero clearance to combustibles.
Edit: ID dimensions are 7 1/16 x 7 1/16
