Grill delicious food on the reinvented 4-burner, black Spirit EP-435 natural gas grill with Side Burner. Two red Boost Burner knobs unleash 40% more power in the Sear Zone. Ignite each burner with one hand with Snap-Jet Ignition and control heat precisely with a full range of temperatures. The porcelain-enameled, cast-iron grates retain heat evenly and the stainless steel Flavorizer Bars catch and vaporize juices, boosting grilled flavor and funneling grease from burners. Outdoor grill also has a cast-aluminum cookbox, warming rack, Grease Management System, four tool hooks, and a cabinet with a door. Make the most of your space by adding a variety of Weber Works accessories (sold separately). Transform your grill into an outdoor griddle with a rust-resistant griddle insert (sold separately). This 4 burner grill's fuel type is Natural Gas and only works with natural gas plumbed to the house. Does not work with bottled gas or bulk liquid propane of any type.
