What would be the clearance for a masonry lined chimney chase? The way I look at it, there is at least 8" between that flue and the wood in that picture (if it is unlined), since it is lined, that adds another inch or so to the distance. Unless there are issues with the mortar joints, I have not been calling that out.

Is there a clearance for that installation?




It does appear that the terra cotta lining is spalling, (indicative of excessive moisture) so I would call it out to be re-lined possibly in need of a crown and/or rain cap.
