The Bayou Classic High Pressure Banjo Burner is one of Bayou Classic's most powerful cast iron burners. This cast iron burner is the same burner found in the KAB4 outdoor propane burner. The BTUs of this burner can produce over 210,000 BTUs plus! In order to obtain a nice, crisp flame, you will need at least 20 PSI regulator. For best results, we suggest purchasing a regulator (7850, 0-30 PSI), a propane hose (7906, 7908, 7910) and orifice (5235). The face of this cast iron burner measures 10 inches in diameter.
