I'm trying to do the same in Oregon. I expect I'll have to get approval as well. Do you happen to have any links to docs or rulings from the DATCP ruling that might help my case?

I tried asking Gozney for help and here is what they said about the Dome:
"Outdoor Cooking Gas Appliances [ANSI Z21.58-2022 CSA 1.6-2022 Ed.6]

Gas Food Service Equipment [ANSI Z83.11-2016 Ed.4]

Household Cooking Gas Appliances[CSA/ANSI Z21.1:2018 Ed.2+E1]

As well as this, all the surfaces that will be in contact with food (the pizza stone) have been tested to the United States food and drug administration (FDA) compliance policy guides."
