It’s not inside the chimney. Interior chimney has no structure outside the house. Think center of home Exterior chimney has a has structure outside, think along an exterior wall.Good to know . This may be a ridiculous question, but what Is considered “combustible” within the chimney? Creosote on the chimney walls? I have heard about chimney fires…..
So the combustibles in question are usually framing, joists and roof sheeting. None of which can be in contact with the chimney and to meet code needs the minimum clearances listed above. Mine doesn’t. So I have insulated liners.
