Lochinvar & A.O. Smith 100173749 Door
The Lochinvar & A.O. Smith 100173749 Heat Exchanger Access Door is a critical combustion chamber component engineered for Lochinvar Knight WB and SNA/SLA series boilers. As a veteran-grade OEM replacement part, this access door (WB model) ensures a high-pressure seal for the heat exchanger assembly, facilitating essential annual maintenance and internal fire tube cleaning. Built with heavy-duty materials to withstand high-thermal stress, it maintains the integrity of the combustion seal to prevent flue gas leakage and ensure peak condensing boiler efficiency. This door is compatible with a wide range of models, including the WHN/WBN 151 through 501 and SLA/SNA series units. When performing a teardown, technicians should inspect the internal refractory and replace associated burner gaskets to ensure a gas-tight fit. Utilizing this Lochinvar certified part ensures original equipment specifications are met, maintaining the system's operational safety and hydronic heating performance without compromising combustion parameters.
Key Benefits- Ensures a precise, airtight seal for the high-efficiency heat exchanger combustion chamber.
- Facilitates direct access for technical inspection and debris removal from the heat exchanger coils.
- Manufactured to A.O. Smith and Lochinvar factory standards for exact fitment on Knight wall-mount boilers.
- Engineered with high-grade steel to resist warping under consistent cycling and high-temperature operation.
- Simplifies the replacement process for contractors during comprehensive boiler service calls.
Is the mounting gasket included with the 100173749 door?
Usually, this part number refers to the metal access door itself. It is standard field practice to source a new graphite or rubber gasket separately to ensure the combustion seal is not compromised during reinstallation.
Which Lochinvar models are compatible with this heat exchanger door?
This door is primarily utilized in the Knight (WB) series, as well as several SLA, SNA, and SNR residential and commercial condensing models. Always cross-reference your specific boiler serial number before installation.
When should this access door be replaced?
Replacement is necessary if the structural integrity of the door is compromised by corrosion, warping from overheating, or if the sight glass or mounting studs are damaged beyond secure fastening.
