Hi I have a question.
We are designing a make up air system for a kitchen exhaust for a beach house at Long Island NY.
The air intake is going to be a louvered penthouse at the roof and the kitchen is at the top floor so the only thing the ductwork is penetrating is the roof.
I want to know if I need smoke damper and fire damper at the location where duct does its penetration since the roof is a fire rated.
IBC is really confusing about where is required to have fire damper and smoke damper and I do not have a copy of NFPA 90A.
Can someone help?
