Do I need to vent my cooktop or range to the outside?
• If your cooktop or range is fueled by natural gas, you certainly should vent to the outside. It is not good practice to use a re-circulating hood with gas appliances. Even with electric appliances, there is the potential for damage with a re-circulating hood from high moisture. Additionally, we recommend that any vent hood with a capacity greater than 300 cfm should have designed make-up air to prevent depressurization issues in the home.
