As with Joseph, I’ve come across the same situation a few times. I’ve tried finding an IRC (2003) that pertains to a fireplace flue exhausting so close to a high-traffic area, but had no luck. From what I read here, it sounds as though there is no code, other than the manufactures recommended clearances.
Since I didn’t know of a code, and didn’t have the Mfr’s installation instructions, ….. I just used my CSC (Common Sense Code), and that’s recommending to the client to keep the area clear by at least 18 – 24 inches. He agreed, said good idea, and we moved on. If someone knows the code for such a set up, please pass it on ? Thanks !
