It is. If you want to get a renovation permit and pass a building code inspection, an outside vent for any gas hookup is mandatory. I live in a nearly 140 year old building, and when the kitchen was renovated around 15 years ago (before my time), they had to put in the vent over the stove…by cutting a hole through the brick and sticking a vent pipe through it. I didn’t mention flashing or insulation, did I? Nope. The vent was the legally-required minimum.
