Some important features are standard on all Broil King Gas Grills, including the burners and Flav-R-Wave cooking system. The burners feature a patented dual tube design, producing 2 rows of flames per burner, to help with even heat distribution. The Flav-R-Wave cooking system protects these burners while instantly vaporizing the food drippings for that excellent bbq flavor. Furthermore, we are pleased to offer the Broil King gas grills that are backed by a lifetime warranty on the lid, burners, and cookboxes.
