Not required but good recommendation. Try this if you like.

RANGE VENTING: Recommend kitchen range vent to exterior. Stoves, whether electric or gas, cause aerosolized moisture and fat droplets that should be exhausted to the outdoors. Range hoods shall discharge outdoors through a single wall duct. The duct serving the hood shall have a smooth interior surface, shall be airtight and shall be equipped with a back draft damper.
