Dwelling unit seperation
One year old townhouse. The fire-resistant wall at the dwelling seperation between units in the attic is penetrated by the following: Refrigerant lines, a 2x8 board and plastic conduit containing communication cables. These are through wall penetrations as far as I can tell.
I have read the code section addressing this several times but am still wondering about the penetrations, particularly the wood and plastic. Any thoughts?
Thanks,
Eric
