Lochinvar & A.O. Smith 100074218 Burner Window
Maintaining a clear line of sight into the combustion chamber is essential for verifying pilot ignition and monitoring flame characteristics. The Lochinvar & A.O. Smith 100074218 Burner Window is a high-temperature OEM replacement part designed for residential and commercial water heaters. This sight glass allows technicians to perform safety inspections and combustion analysis without breaking the seal of the FVIR (Flammable Vapor Ignition Resistant) chamber. Constructed from durable, heat-resistant materials, this burner window ensures long-term clarity under high-thermal stress. When performing a water heater repair, replacing a cracked or soot-covered window is a critical step in restoring the system's HVAC safety standards. This specific component is a direct match for various Lochinvar and A.O. Smith burner assemblies, ensuring a precision fit on the inner door. As a veteran-grade HVAC replacement part, it is engineered to withstand the rigorous internal pressures of high-efficiency water heaters while providing the necessary visibility for routine calls or emergency troubleshooting.
Key Benefits- OEM Compatibility: Precision-engineered for a seamless fit on A.O. Smith, Lochinvar, and State water heater inner door assemblies.
- High-Temperature Durability: Thermal-resistant glass prevents cracking and warping during prolonged burner operation.
- Operational Safety: Facilitates pilot light visual verification and flame pattern monitoring without exposing the chamber to external air.
- FVIR System Integrity: Maintains the critical seal required for Flammable Vapor Ignition Resistant technology to function correctly.
How do I know if I need a new burner window?
If the existing glass is cracked, heavily discolored by soot, or missing, it must be replaced immediately. A compromised burner window can lead to improper airflow or vacuum leaks within the combustion chamber.
Can I use a generic glass substitute for this part?
It is not recommended. HVACR technicians use the 100074218 because it is rated for specific thermal expansion and pressure ratings required by Lochinvar and A.O. Smith units to prevent dangerous leaks.
Does this part include the gasket?
This SKU covers the burner window glass. It is a best practice to inspect the sight glass gasket during installation and replace it if the seal shows any signs of compression set or degradation.
