I don't know what to say. What do you feel the objection to putting them back, specifically, is? Every large hood that I've ever done has those mason jar type fixtures up in there. I see that 410.4(C) can be complied with if you use those vapor tight fixtures and either stub through at each fixture or wire in EMT or IMC. It doesn't seem that NFPA 96 has the force of law in your state, near as I can gather. Is this a resi or commercial kitchen?
