Lochinvar & A.O. Smith 100110901 Window Observation
Upgrade your system monitoring with the Lochinvar & A.O. Smith 100110901 Window Observation assembly. This genuine OEM sight glass replacement is a critical component for service technicians performing routine combustion analysis or checking burner flame quality in high-efficiency Lochinvar boilers and A.O. Smith water heaters. Designed to withstand the thermal stress of sealed combustion chambers, this durable observation port ensures an airtight seal, preventing flue gas leakage while providing a clear line of sight for HVAC flame inspection. Unlike generic alternatives, the 100110901 is engineered for precise fitment in specific hydronic and commercial water heating units, maintaining the pressure integrity of the heat exchanger housing.
As a seasoned contractor knows, a clouded or cracked boiler sight glass can lead to inaccurate diagnostic reads or dangerous vacuum leaks. This kit typically includes the necessary high-temperature fiber gaskets to ensure a professional-grade repair. Whether you are servicing a commercial boiler or a residential high-recovery heater, using the exact 100110901 OEM part is the only way to guarantee your equipment continues to meet factory specifications for safety and performance.
Key Benefits- Precision OEM Fit: Direct replacement for part number 100110901 and obsolete A.O. Smith number 9006102215.
- High-Temperature Durability: Engineered to handle extreme thermal cycling without cracking or clouding.
- Combustion Safety: Restores the airtight seal required for balanced flue and sealed combustion systems.
- Easy Diagnostics: Provides crystal-clear visual access to verify pilot ignition and main burner flame pattern.
When should the 100110901 window be replaced?
You should replace the observation window if you notice any hairline cracks, significant soot buildup that cannot be cleaned, or if the surrounding gasket has become brittle and is allowing air bypass into the combustion chamber.
Are the gaskets included with the observation window?
Yes, this genuine OEM part typically includes the specialized gaskets required to create a heat-resistant seal against the boiler or heater casing.
Which models is this observation port compatible with?
This part is widely used across the Lochinvar Knight and Copper-Fin lines, as well as several A.O. Smith commercial series. Always cross-reference your specific model's manual to ensure 100110901 is the correct fit for your configuration.
