Lochinvar & A.O. Smith 100173799 Door Kit
The Lochinvar & A.O. Smith 100173799 Door Kit is a field-critical heat exchanger access door kit designed for high-efficiency hydronic boilers and volume water heaters. This OEM assembly, which is functionally identical to WTR3086, serves as the primary seal for the combustion chamber, ensuring proper pressure vessel integrity and thermal containment. When performing a Lochinvar heat exchanger cleaning, replacing the door kit is essential to restore the airtight seal required for optimal boiler combustion efficiency. The kit includes a precision-machined Lochinvar burner access plate and high-temperature insulation capable of withstanding extreme thermal cycles without degradation. Engineered for use in A.O. Smith Cyclone series and various Lochinvar KBX/WBX models, this commercial water heater repair part prevents flue gas leakage and maintains the necessary internal geometry for stable flame patterns. Utilizing genuine 100173799 replacement parts ensures that the equipment remains within manufacturer specifications for safety and emissions.
Key Benefits
- Direct OEM Compatibility: Verified fit for widespread commercial platforms, replacing retired part numbers and WTR3086 equivalents.
- Thermal Sealing Integrity: High-grade refractory insulation prevents heat loss and protects external components from over-temp conditions.
- Enhanced Serviceability: Facilitates standard maintenance intervals by providing a reliable combustion chamber access door that resists warping.
- Optimized Air-Fuel Mixture: Maintains the critical seal necessary to prevent vacuum leaks that can destabilize high-altitude or low-NOx burner performance.
Common Questions
What models are compatible with the 100173799 door kit?
This kit is compatible with specific Lochinvar Knight and A.O. Smith Cyclone models; technicians should verify the specific heat exchanger size before installation.
Is the insulation included in the 100173799 kit pre-installed?
Yes, the kit typically includes the refractory insulation pre-mounted to the door plate to ensure a flush seal against the heat exchanger flange.
Can I reuse the old hardware with this access door?
While the plate may fit, it is industry best practice to inspect all mounting bolts for fatigue and replace the gasket to ensure a gas-tight seal.
