Lochinvar & A.O. Smith 100157628 Cleaning Kit

The Lochinvar & A.O. Smith 100157628 Heat Exchanger Cleaning Kit (formerly KIT30064) is an essential OEM maintenance kit for maintaining peak thermal transfer in condensing boilers and water heaters, including the Armor series. As a veteran tech knows, flue-side fouling and scale buildup act as thermal insulators, driving up stack temperatures and forcing the burner to over-fire. This 100157628 cleaning kit provides the specific mechanical tools, such as the 1/4" x 12" and 24" brushes, required to reach deep into the heat exchanger coils to clear combustion byproducts without damaging the internal surfaces. Regular use of this boiler heat exchanger cleaner prevents condensing boiler scale buildup, which is critical for preventing high CO levels and nuisance lockouts. For field technicians performing annual service, keeping the 100157628 technical part in the van ensures you can restore factory-spec combustion stability and improve system longevity on any Lochinvar Knight or A.O. Smith high-efficiency unit.

• Full Combat Compatibility: Identical to the legacy KIT30064, ensuring seamless integration with existing service protocols for Lochinvar and A.O. Smith models.
• Restores Efficiency: Effectively removes heat exchanger scale and sediment to lower fuel consumption and return the unit to its AHRI-rated performance.
• Precision Access: Includes professional-grade brushes (12-inch and 24-inch lengths) designed to navigate the tight tolerances of high-efficiency heat exchangers.
• Reduces Callbacks: Helps eliminate high flue gas temperatures and combustion abnormalities that lead to mid-season system failures.

How do I know if the heat exchanger needs cleaning?
Monitor the stack temperature and CO levels. If you see rising flue temps or high carbon monoxide during your combustion analysis, the coils likely have significant byproduct buildup that requires the 100157628 kit.

Is this kit compatible with the Armor AW500-800 series?
Yes, this 100157628 cleaning kit is specifically engineered for Armor condensing water heaters and various Knight boiler configurations to ensure thorough flue-side maintenance.

Can I use this for both Lochinvar and A.O. Smith units?
Correct. Since both brands often share internal heat exchanger designs in their condensing lines, this OEM cleaning solution is the standard for both manufacturers.
