Lochinvar & A.O. Smith 100135315 Burner Replacement Kit
The Lochinvar & A.O. Smith 100135315 Burner Replacement Kit is a critical combustion component designed for high-output 800,000 BTU condensing boilers. Engineered as a direct fit for the KBN800 series, this 800K BTU burner assembly ensures precise air-gas mixing for optimal thermal efficiency and low-NOx emissions. As a veteran technician knows, maintaining the integrity of the burner orifice and surface is paramount to preventing resonant "booming" or "wumping" during ignition cycles. This OEM Lochinvar burner kit includes the necessary high-temperature gaskets (part 100233594) required to re-establish a gastight seal between the burner plate and the heat exchanger access door.
When swapping this assembly in Knight XL models such as the KBN800, KBN801, OKN801, and AWN801PM, always inspect the surrounding refractory lining for cracks. Carbon buildup on the burner surface can lead to flame rectification issues or "Flame Fail Running" lockouts. Utilizing this genuine Lochinvar replacement part maintains the original equipment’s modulation ratios and combustion stability, protecting the stainless steel heat exchanger from concentrated hotspots and premature fatigue.
Key Benefits- Precision Engineering: Specifically calibrated for Lochinvar Knight XL 800,000 BTU systems to ensure a stable flame pattern and efficient combustion.
- Comprehensive Kit: Includes the burner assembly and sealing gaskets to provide a complete solution for annual 12-month maintenance or corrective repairs.
- Restored Efficiency: Replaces degraded or clogged burner surfaces to eliminate short-cycling and improve overall system response time.
- Perfect Compatibility: Direct Lochinvar 100135315 crossover for several large-scale residential and commercial boiler configurations.
Does this kit include the flame sensor and ignitor?
No, this kit includes the burner and burner gaskets. While the 100135315 is the primary combustion component, we recommend inspecting the 100165931 flame sensor and 100165920 ignitor separately during the burner swap to ensure the entire assembly is to spec.
Why is my KBN800 making a loud vibration on startup?
Vibrations or "humping" noises often indicate a fouled burner surface or incorrect gas-to-air ratios. Installing a fresh Lochinvar burner replacement and performing a full combustion analysis typically resolves these resonance issues.
Is a gasket required for this installation?
Yes, a new burner gasket is mandatory to prevent combustion leaks. This kit includes the necessary high-grade OEM gaskets to ensure a proper seal at the combustion chamber interface.
