A gas broiler burner built from cast iron, designed for use in high-heat commercial cooking systems where controlled flame output is required. It features a 21-1/2" overall length with a 16-1/2" active burn zone, along with an integrated air shutter that allows adjustment of the air-to-gas mix for proper ignition and combustion behavior. The cast iron body supports high-temperature exposure typically found in continuous broiling and grilling operations. This burner is commonly installed in commercial broilers and heavy-duty grilling equipment across restaurant and institutional kitchen setups. When the burner becomes clogged, deformed, or uneven in output, heat spread may become inconsistent, and cooking zones may lose balance. Replacement of the burner assembly restores flame distribution and supports steady heating across the broiler surface, especially in gas-powered cooking environments operating under constant load.
Equipment Compatibility:
Key applications for this cast iron Randell broiler burner include commercial broilers and high-output grilling equipment used in foodservice kitchens. This Burner RB-3 is compatible with commercial equipment from leading brands such as Randell, Rankin Delux, and related RB-8 and TB-8 style broiler equipment, and more, where controlled flame output and consistent gas combustion are required for normal operation.
