Lochinvar & A.O. Smith 100142506 Gasket
The Lochinvar & A.O. Smith 100142506 Gasket is a critical OEM manifold gasket designed to maintain air-to-gas ratio integrity in heavy-duty commercial heating systems. As a genuine boiler replacement part, this high-temperature gasket is precision-engineered to prevent combustion leaks and ensure optimal thermal efficiency. Specifically built for high-performance units, this 100142506 kit provides the durable seal required to withstand the thermal expansion and contraction cycles typical of industrial boiler manifolds. For contractors performing annual maintenance or emergency repairs, utilizing this Lochinvar burner gasket is the standard for restoring factory-spec performance. This component is compatible with several large-scale units, including the Power-Fin FBL5000, FBL6000, FBN5000, and FBN6000 models. Proper installation of this manifold sealing kit is essential for avoiding carbon monoxide risks and pressure drops within the burner assembly. We recommend checking the manifold cover nuts and following a star-pattern tightening sequence to the specified foot-pounds to ensure a gas-tight seal.
Key Benefits- OEM Precision: Guaranteed fit for Lochinvar Power-Fin FBL and FBN 5000-6000 series boilers.
- Thermal Resistance: Specifically formulated for the high-intensity heat environment of the gas/air manifold assembly.
- Leak Prevention: Eliminates gas bypass and air infiltration, maintaining consistent combustion system performance.
- System Reliability: Protects the heat exchanger and burner components from hot gas damage.
Which boiler models use the 100142506 manifold gasket?
This gasket is primarily designed for the Lochinvar Power-Fin series, specifically models 5000 and 6000 (FBL5000, FBL6000, FBN5000, FBN6000).
Should I replace the manifold gasket every time the burner is serviced?
Yes. In commercial applications, any time the burner assembly or manifold cover is removed, the gasket should be replaced to ensure a fresh, calibrated seal that can withstand the pressure of the blower system.
What is the recommended torque for the manifold nuts?
For these high-output units, manifold flange nuts typically require 25 ft-lbs of torque, while burner mounting nuts range between 8 to 12 ft-lbs depending on the specific model frame; always consult the service manual for your specific serial number.
