Raypak 350350F Orifice-Burner Pro #59

The Raypak 350350F Orifice-Burner Pro is a gas flow metering component designed for regulating fuel delivery in HVAC heating systems. Configured with a #59 orifice size, it controls the volume of gas entering the burner assembly to support a stable combustion feature and controlled heat generation during operation. It is commonly installed in boilers and gas-fired heating equipment where calibrated fuel distribution is required for burner efficiency and consistent flame performance. Within the combustion assembly, the orifice operates as a gas control element that supports fuel regulation, combustion balance, and coordinated heating system operation.
