Description
The Raypak 350079F Natural Gas Orifice is a fuel metering component used in natural gas-fired heating equipment. Featuring a 50 orifice size, it regulates the volume of natural gas delivered to the burner, helping establish the correct fuel flow for combustion. Positioned within the burner assembly, it works with the air supply system to support an appropriate air-to-fuel mixture during operation. Commonly applied in boilers, water heaters, and other gas heating equipment within HVAC systems, the orifice plays an essential role in maintaining consistent burner performance and controlled heat generation.
