The Bayou Classic high pressure cast iron fry burner is considered a high pressure burner but in Cajun terms is low pressure. This cast iron fry burner performs well when used with 10 PSI regulators. If you put a higher BTU, the flame is less controllable. You will also have an issue with the burner receiving too much propane, which will result in your flame blowing itself out. We do use this burner in the SQ14 propane outdoor cookers and 1114 stainless steel propane outdoor cookers. The Bayou Classic high pressure cast iron fry burner includes the air shutter. Orifices are available for purchase separately. The face of this cast iron burner measures 5 1/2 inches in diameter. Many people have asked us for a BTU for this cast iron propane burner. The actual cast iron element (burner) does not determine the BTUs. The regulator determines the BTUs. You can use the 10 PSI regulator kit with it. Features: Dimensions: 6 inch diameter and 11 inch length. Includes air shutter and spring. Use with 1114 and SQ14 propane burners. May be used with 10 PSI regulator. BTU rating determined by the PSIs of your regulator.
