In Minnesota at least, a gas cook stove does indeed require ,by code,
a vent which goes outside. I'm sure that's true of many other states
as well. I have seen unvented stoves but they have never been seen by
a building inspector, I bet.

I can tell you there are hundreds of thousands of gas ranges that have no
vents. Not required in PA or CT but I don't know about other states. Yes,
they have been seen by the building inspector.
