Commercial Kitchen Door Fire Rating

[townofgardiner]

I'm working with an architect on confirming the rating for a door leading into a commercial kitchen from a dining room. He specified a standard grade 0 hour rated door with standard glass. I didn't approve the specifications and sent notes back after plan review that said the door should have fire rated ceramic glass. He's insistent that the door doesn't need to be fire rated or need to have fire rated glass. It's a commercial building with a dining room and kitchen. He also specified that the walls for the kitchen separating dining from kitchen can be zero hour rated. I'm searching for references in the code to confirm.

The kitchen is an A-2 under the IBC

303.3 Assembly Group A-2.
Group A-2 occupancy includes assembly uses intended for food and/or drink consumption including, but not limited to:

Banquet halls

Casinos (gaming areas)

Nightclubs

Restaurants, cafeterias and similar dining facilities (including associated commercial kitchens)

Nothing outright in the code that requires a rating there...

Unless there is a fire compartment due to excessive fire area, the kitchen and dining area are both classified A-2 and no separation would typically be provided.
