Lochinvar & A.O. Smith 100189387 Valve

Lochinvar & A.O. Smith 100189387 Valve

The Lochinvar & A.O. Smith 100189387 Valve is a Liquid Propane (LP) gas valve assembly designed specifically for high-efficiency heating applications, including the Lochinvar Copper-Fin II and FTX 725 series. As a critical component in the gas valve kit, this assembly utilizes a negative pressure regulation system to ensure precise fuel-to-air ratios throughout the firing cycle. For technicians troubleshooting ignition failure or flame failure codes like E384 or P12, this OEM replacement provides the necessary manifold pressure stability required by microprocessor-based integrated control modules. The 100189387 gas valve features redundant internal valve seats and built-in low gas pressure regulators to maintain consistent performance in both residential and commercial HVAC environments. Utilizing OEM Lochinvar replacement parts ensures full compatibility with the combustion air blower and smart system control panels, maintaining the 85% thermal efficiency rating of the original equipment while providing reliable negative pressure gas valve operation during the hot surface ignition sequence.

Key Benefits:

  • Precise Negative Pressure Regulation: Engineered to match the blower-driven suction requirements of Lochinvar boilers, ensuring proper 0" w.c. equivalent during combustion.
  • Direct OEM Replacement: Eliminates compatibility issues in A.O. Smith and Lochinvar water heaters, fitting the exact 100189387 mechanical and electrical footprint.
  • Enhanced System Safety: Incorporates redundant valve seats to prevent gas bypass and ensure a secure shut-off during flame failure events.
  • Optimized Energy Efficiency: Supports the high thermal efficiency standards of the Copper-Fin II series by maintaining a stable fuel mixture for clean combustion.

Common Questions:

What are the symptoms of a failing 100189387 gas valve?
Common indicators include persistent ignition fault or flame failure codes (such as E384), a failed spark test where 0" w.c. pressure is not reached on a manometer, or an audible failure of the solenoid to click open despite receiving proper voltage from the control board.

Is this gas valve compatible with Natural Gas units?
No, the 100189387 is a Liquid Propane (LP) kit. Installing an LP valve on a Natural Gas system can cause hazardous combustion conditions. Always verify the fuel type on the equipment rating plate before installation.

Can I replace just the solenoid on this valve?
It is standard practice among veteran technicians to replace the entire gas valve kit assembly. This ensures the internal regulator and redundant seats are also new, preventing future boiler downtime and ensuring long-term reliability.
