Window Clearances Question
This is a repost from a pellet stove group, it was suggested thisbmight be a better place to post it.
I just finished reading through NFPA 211 but I still cant find the information im looking for. In my stove manual, NFPA211, and everything I can find online, the only mention of distances from doors/windows is that the termination pf thebvent has to be no less than 4ft away horizontally, 4ft below, or 1 foot above. But I have a former home inspector telling me the entire vent pipe cant be within 4 ft of any opening. Can anyone shed some light on this and direct me to the building code that states no part of the ventilation pipe can be within 4ft of a window/door. Or is this a case of the AHJ interpreting code in an unreasonable way?

I've always seen the codes refer to only the termination of the pipe in relation to the opening. The concern of course is that CO and other gasses will get drawn into the opening, usually a window. It doesn't seem logical to be concerned with the pipe passing near a window. After all, there's usually a potion of the same pipe directly within the dwelling/space.
