It does seem odd that the home heating natural gas appliances (water heater, furnace, etc.) have to pass Combustion Appliance Zone (CAZ) testing. It's basically a smoke test (sometimes literally) to ensure that the products of combustion are being safely vented out through the stacks in the house.

While this exists to some extent for gas stoves, it doesn't seem to be mandatory to ensure a gas stove/vent hood is compliant.
