Natural Gas Orifice
A natural gas orifice is a precisely sized hole that controls the flow of natural gas to a burner, ensuring the correct fuel-air mixture for efficient combustion and heat output. Orifices for natural gas are larger than those for propane because natural gas has lower pressure and volume, and the correct size is determined by factors such as gas pressure, appliance BTU, and the number of burners.
Function Gas Flow Control: The orifice's primary function is to restrict the gas flow to the burner to match the appliance's design requirements. Fuel-Air Mixture: By controlling the gas flow, the orifice helps create a proper fuel-air mixture, which is essential for a stable, efficient, and clean flame.
Key Characteristics Size Matters: The size of the orifice, stamped on the part or found in the appliance manual, dictates the amount of gas that can pass through, directly affecting the burner's BTU output. Larger for Natural Gas: Natural gas requires larger orifices compared to propane because it has lower pressure and volume. Precise Measurement: Orifice sizes are measured in specific drill sizes or gauge numbers, with larger numbers indicating smaller diameters.
When Orifices Are Replaced
Appliance Conversions: When converting an appliance from propane to natural gas, or vice-versa, the orifices must be replaced with ones sized for the new fuel type.
Clogged Burners: Orifices can become clogged with debris, which can lead to poor flame quality, incomplete combustion, or weak flames.
Replacing Faulty Parts: They are also replaced when a main burner valve or other components are exchanged.
How to Identify and Replace an Orifice
Locate the Orifice: The orifice is usually found on the main burner valve or at the end of the burner tube.
Check for Stamping: The orifice size is often stamped directly onto the brass body of the orifice.
Consult the Manual: For proper sizing and conversion, always consult the appliance manual for specific orifice numbers and recommended sizes for natural gas.
Safety First: Turn off the gas supply before performing any work on orifices to prevent leaks.
