Do gas cooktops or gas ranges need to be vented to the exterior of the home? You might be surprised to learn that venting gas cooktops (for example, via a range hood) is not required in the province of Ontario and other jurisdictions. A vent is however recommended to remove excess heat, steam, grease, smoke and odours.
Cooktops, stovetops & ranges (sometimes called stoves) require have a minimum clearance to combustible materials regardless if they’re gas or electric. Further, Gas Code requires these gas appliances be installed to manufacturer’s specifications.
While gas cooktops / ranges can vent directly into a home, newer homes require a range hood vent as part of the home’s ventilation system. Even though these gas cooktops / ranges burn cleaner than they once did, we recommend venting moisture and harmful by-products of combustion to the exterior of the home in order to make your indoor quality air as healthy as possible. Of course, carbon monoxide (CO) detectors are a must with all fossil fuel (e.g. natural gas, propane, oil, wood, etc.) burning appliances in your home.
Thinking of buying a home with a gas cooktop / range or already own one and unsure what to do? Protect yourself…get it inspected!
