The American Range A14035 Grill Cast Iron Jet Burner is a gas burner component used in compatible commercial grill assemblies. Its jet burner construction directs gas through the burner ports, where the fuel mixes with air and ignites to produce the flame needed for cooking. The cast iron body provides the physical structure for the burner within the grill compartment. With a 9-inch diameter, its size corresponds to the designated mounting area.
