The Spirit E-330 BBQ grill includes a handy 10,000 BTU side burner for cooking accompaniments and a 7,500 sear station burner that boots heat to quickly sear foods, then turns off for regular grilling. Other features include long-lasting porcelain-enameled cooking grates and porcelain-enameled Flavorizer Bars. Positioned above the burner tubes and below the grates, these V-shaped Bars shield burner tubes from port-clogging debris. They also serve to catch and vaporize food drippings, creating the smoke that flavors food. The Spirit E-330 LP gas grill carries a 10-year warranty on the porcelain-enameled lid and burner tubes and a 5-year warranty on grates and Flavorizer Bars. Not available in natural gas.
