Lochinvar & A.O. Smith 100159009 Conversion Kit

The Lochinvar & A.O. Smith 100159009 Conversion Kit is a critical OEM component designed for field-converting high-efficiency heating systems from natural gas to liquid propane (LP). This propane conversion kit is engineered for precision, ensuring the burner receives the correct fuel-to-air ratio for stable combustion and optimal thermal output. As a direct replacement for the LPK3947, it integrates seamlessly with Lochinvar Knight and A.O. Smith condensing boilers and water heaters. Technicians should verify compatibility with models such as the AWN199, KBN210, WBN210, and WB150/210 series. Utilizing a genuine Lochinvar 100159009 kit maintains the equipment’s UL/CSA certification and ensures the internal gas valve and orifices align with LP manifold pressure requirements. For a successful boiler to LP conversion, contractors must perform a full combustion analysis post-installation to calibrate CO2 and CO levels according to manufacturer specifications.

Key Benefits:

• OEM Compatibility: Specifically designed for Lochinvar 100159009 architectures, ensuring a perfect fit and reliable performance in Knight water heaters and boilers.
• Precision Orificing: Includes technically accurate components to manage the higher BTU content of liquid propane compared to natural gas.
• Direct Replacement: Serves as the official LPK3947 conversion kit substitute, streamlining inventory for service vans.
• System Stability: Prevents delayed ignition and soot buildup by providing the correct fuel delivery for LP-fired applications.

Common Questions:

Which specific models use the 100159009 conversion kit?
This kit is primarily utilized for the Lochinvar Knight KB210, WB210, and AWN199 units. It is essential to cross-reference your unit's serial number and data plate to confirm this is the correct liquid propane conversion part for your specific BTU input.

Do I need to change parameters in the control board after installation?
Yes. Beyond the physical orifice installation, technicians must typically adjust the combustion settings via the SMART SYSTEM control and perform a high-fire/low-fire combustion test to ensure safe operation after the LP gas conversion.

Can this kit be used for other gas types?
No, this is a dedicated LP conversion kit. Using these components for anything other than liquid propane applications will result in improper combustion and potential equipment damage.
