Weil-mclain wm560528987 Natural Gas Main Burner Orifice

Product Description

The Weil-McLain wm560528987 Natural Gas Main Burner Orifice is a direct replacement component designed for use in Weil-McLain gas-fired boilers and heating systems. This orifice controls the flow of natural gas into the main burner assembly, metering fuel at a precise rate to support stable, efficient combustion. Proper orifice sizing is critical in any gas appliance. A correctly sized orifice delivers the right air-to-fuel ratio, which affects flame quality, heat output, and overall system efficiency. HVAC technicians and boiler service professionals rely on OEM-matched orifices like this one to restore original equipment performance after wear, clogging, or damage. The wm560528987 is engineered to Weil-McLain specifications, so it fits and functions exactly as the factory-installed part. Natural gas burner orifices are small but essential components. Over time, they can become partially blocked by debris, corroded, or physically damaged during service. Replacing a worn or damaged orifice restores proper gas flow, eliminates uneven flame patterns, and helps the boiler meet its rated BTU output. Using a non-OEM or incorrectly sized orifice can lead to incomplete combustion, sooting, elevated carbon monoxide levels, and reduced heat exchanger life. This part is the correct solution for technicians working on Weil-McLain residential or light commercial boiler systems that use natural gas as the fuel source. Whether you are performing a scheduled tune-up, diagnosing a combustion problem, or completing a burner assembly rebuild, having the correct main burner orifice on hand keeps the job moving. The wm560528987 weighs approximately 0.99 pounds, making it easy to transport and stock in a service van or parts inventory.
