    Greetings Charlie! Love this forum. You do an excellent job. My question is regarding 300.21. There seems to be some debate on whether all wall penetrations need to be fire stopped or just penetrations through fire rated walls. Could "Substantially increased" apply to any wall penetration? Local AHJ's seem to differ a bit here as well. What is your take? Thank you! Jason Rolf
