JennAir JGD3430GB JX3 30" Black Gas Downdraft Cooktop
The JennAir JGD3430GB JX3 30" downdraft cooktop fuses elements you'd find in a classic kitchen appliance, like gas cooking and four burners—but it also introduces new features like the luxury JX3™ downdraft ventilation system. Instead of a range hood, the cooktop's built-in downdraft pulls steam, smoke and odor down into the appliance and out of the space entirely. Cook multiple dishes on all four burners without fear; if anything starts to sizzle too much, the JX3™ system is at the ready. The ventilation system features three speeds that can pull away steam, smoke and odor before they crowd your JGD3430GB. The JGD3430GB's 297 CFM Motor Class blower system is so effective and out of the way that you'll barely know it's there—and there's no range hood to interrupt your home's aesthetic.
High-Output Heat & Low-Output Simmers
JennAir is known for luxe appliances, and the JGD3430GB is the perfect example of an elevated classic. With four impressive burners, users have everything they need to make everyday meals and host the occasional dinner party. Home chefs go beyond thanks to the luxury cooktop's impressive build quality and capabilities. Between removable brass burners that deliver effective heat and look beautiful, the JGD3430GB visually stuns before it's even turned on. Meanwhile, two burners are dedicated to vastly different heat levels: the 17,000 BTU high-output burner and the 5,000 BTU low-output burner. Use the flexible JGD3430GB to boil water, sear steaks and more. And when it's time to turn the heat down, move to the 5,000 BTU burner. It's a great space to simmer, melt chocolates and even warm leftovers with the right cookware. Between all four burners, finding the perfect spot on the JGD3430GB to cook your recipes is easy—and if things get too hot, the built-in downdraft is there to whisk away smoke.
A Unique, Dark Style for the Modern Kitchen
The JennAir JGD3430GB steers away from stainless steel and moves toward shining black metal for the ultimate in contemporary style. Thanks to the metallic look of the brass burners and the dark control knobs, this kitchen appliance is an eye-catcher with elegance.
