A:Answer Hi CJ- This is Sue at GE Appliances. Thanks for considering our GE Gas Cooktop. Model JGP329DETBB is not equipped with downdraft venting. Check out the Installation Instructions online at the following link: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=31-10860-1.pdf - While a vent hood is not required by GE, it is recommended. Vents help to effectively remove smoke, grease, odors and moisture from the room. We suggest to check local codes for any venting requirements. Thanks for checking with us!
