Jenn-Air's new collection of downdraft cooktops offer ventilation and clean air to high-rise residents, condo owners and other consumers who can't run ductwork or vent to the outdoors. Available 30- and 36-inch sizes, the gas cooktops feature an ultra-high-output burner with up to 17,000 Btus, while the electric models offer electronic touch controls. The exclusive duct-free downdraft (sold separately) allows the 425-475 CFM ventilation system to be installed without major renovations to accommodate ducting. Jenn-Air
