A:Answer Hi grammy,
Thanks for reaching out to us! We appreciate your interest in GE Appliances, and would be happy to help you with this range hood. The term "convertible" (also called recirculating) vent hoods can be easily converted to be non-vented. This model range hood is manufactured with vents on the top rear of the appliance, so it is already set up for external exhaust. For more information on ventilation, use the following link:

We hope this information is helpful. If any more questions should arise, feel free to ask. Thank you for choosing GE Appliances, and have a great day!
