A:Answer Hi JMom - Thanks for your interest! Model JVW5301EJES is designed for wall mount only and cannot be installed above an island. Our GE Profile™ 36" Island-Mount Chimney Hood Model #: PV977NSS is offered in 36" and stainless steel only. We suggest Custom Hood Insert w/ Dimmable LED Lighting Model #: UVC7300SLSS. For guidance, take a look at the installation instructions at the following link: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-80797-3.PDF - Also, most range or cooktop models do not require a ventilation system or have a CFM requirement; however, we recommend checking the local residential codes in your area to see if one is required.
