Looking Good Cooktop Ventilation Requirements
To Vent or not to Vent a cooktop.
Cooktop ventilation requirements. For example a 100000 BTU stove needs at least a 1000 CFM range hood. For electric cooktops a 5 127 cm diameter round vent may be used for venting straight out the back of the cooktop and directly through the wall for 10 ft 30 m or less. Consult with your local building permit and code department to ensure that your equipment and its installation complies with their requirements.

Where fittings are used the maximum length of the exhaust duct shall be reduced in accordance with Table M1502451. Simply put the higher the CFM the more air the hood vents out of your kitchen. Induction cooktops do not need much venting as gas or electric cooktops do.
