Purpose of Range Hoods

Range hoods are designed to remove smoke, grease, and other airborne contaminants from the kitchen air. They help to improve indoor air quality and reduce the risk of fire hazards.

• Vent Hood Extension: The vent hood must extend at least 6 inches beyond the edge of the cooking surface.
• Makeup Air: If the range hood is ducted to the outside, makeup air must be provided to the kitchen to prevent negative air pressure.
