This Burnham Commercial Conversion Kit is designed to convert Liquid Propane (LP) fuel systems to Natural Gas (NAT) systems. The kit includes all necessary components for a complete conversion, ensuring compatibility with Burnham Commercial appliances. It is engineered to maintain the efficiency and performance of the original equipment. The kit contains a regulator, burner orifices, and a manifold pressure tap plug. The regulator adjusts the gas pressure from the supply line to match the appliance's requirements. The burner orifices are designed to control the amount of gas flow into the burner. The manifold pressure tap plug is used to seal off the manifold pressure tap after adjusting for proper operation. This conversion kit allows for an efficient and safe transition from LP to NAT fuel systems in commercial settings.
