Lochinvar & A.O. Smith 100274105 Igniter Assembly

Lochinvar & A.O. Smith 100274105 Igniter Assembly

The Lochinvar & A.O. Smith 100274105 Igniter Assembly is a critical combustion component engineered for high-performance gas-fired boilers and water heaters. As a veteran-grade hot surface igniter, this assembly is designed to provide rapid, consistent ignition of the gas-air mixture, ensuring a stable combustion cycle and reducing the risk of "flame fail" lockouts. This OEM replacement part includes a specialized gasket for igniter sealing, maintaining atmospheric integrity within the combustion chamber. Constructed with 1/2" NPT stainless steel housing, it offers high thermal resistance and durability under extreme cycling conditions. For technicians, this igniter spark assembly serves as a direct-fit solution for Lochinvar boiler parts and A.O. Smith systems, optimizing the heating system ignition sequence to prevent delayed ignition events. By maintaining precise resistance levels, it supports the control board's flame sensing requirements, critical for ensuring safe and efficient HVACR equipment operation across residential and commercial applications.

Key Benefits
  • Direct OEM Compatibility: Perfectly fits professional-grade Lochinvar and A.O. Smith heating units.
  • Enhanced Ignition Consistency: Minimizes ignition lag and prevents nuisance system shutdowns.
  • Integrity-Seal Gasket: Includes a high-temperature gasket to ensure a leak-proof seal during installation.
  • Rugged Construction: Built with stainless steel threads and durable ceramic insulation for reliable service.
  • Efficiency Optimization: Delivers a reliable spark to maximize fuel-to-air combustion efficiency.
Common Questions
  • How do I test the 100274105 igniter for failure? Use a multimeter to check for continuity or specific resistance ranges across the leads; an open circuit or infinite resistance typically indicates a cracked or burned-out element.
  • Can I touch the igniter element during installation? No. Skin oils can create hot spots on the ceramic or silicon carbide surface, leading to premature failure. Handle by the base only.
  • Does this assembly include the necessary mounting gasket? Yes, the 100274105 comes with the required gasket to ensure a proper airtight seal against the manifold door.
