The 583011 NAT 75,000 #19 .166 Main Burner Orifice is a critical natural gas component that precisely controls fuel flow to your burner, ensuring optimal heat output and even cooking performance. This orifice is specifically sized for 75,000 BTU natural gas burners and is compatible with Southern Pride BBR Series (BBR-79-1, BBR-79-2, BBR-79-2/3), BMJ Series (BMJ-1000, BMJ-350i), SPK Series (SPK-280, SPK-500), SPX Series (SPX-300), and XLR Series (XLR-350) smokers and BBQ pits.
Replace this orifice if you notice inconsistent flame patterns, reduced heat output, or uneven cooking temperatures. Regular inspection during annual maintenance helps prevent performance issues. Installation is straightforward for experienced users, though professional installation is recommended to ensure proper gas flow and safety compliance. Always consult your equipment manual for specific installation procedures.
