Lochinvar & A.O. Smith 100108432 Valve
The Lochinvar & A.O. Smith 100108432 is an OEM natural gas valve designed for high-efficiency commercial and residential heating platforms. Operating on a standard 24V gas valve circuit, this component is factory-calibrated to a 4" WC (Water Column) manifold pressure to ensure precise fuel regulation and optimal combustion performance. Featuring a 3/4" NPT connection, it provides the necessary flow capacity for mid-to-high BTU applications and is a direct replacement for various legacy water heater and boiler controls.
As a veteran technician knows, maintaining the correct flame signal and manifold pressure is critical for system longevity. The 100108432 gas control valve is engineered to withstand the rigorous duty cycles of Lochinvar boilers and A.O. Smith water heaters, providing reliable pilot or direct ignition sequencing. When replacing a failed solenoid or diaphragm within the gas train, using this genuine OEM HVAC part ensures the unit stays within original manufacturer specifications and prevents premature heat exchanger fatigue caused by improper gas-to-air ratios.
Key Benefits:
- OEM Compatibility: Precision-engineered for a seamless fit in Lochinvar and A.O. Smith equipment, eliminating the need for field modifications.
- Optimized Regulation: Pre-set to 4" WC for stable natural gas delivery and consistent burner performance.
- Standardized Voltage: Operates on a 24VAC control loop, making it compatible with most modern integrated furnace controls and thermostats.
- Heavy-Duty Construction: Built with high-grade internals to resist debris buildup and ensure clean shut-off during cycles.
- High-Flow Design: The 3/4 inch gas valve inlet/outlet provides the throughput required for demanding heating loads.
Common Questions:
Can I use this valve for Propane (LP) applications?
No, the 100108432 is specifically calibrated for natural gas at 4" WC. Using it for LP without a manufacturer-approved conversion kit is unsafe and will result in improper combustion.
Is this a direct replacement for part 9000547005?
Yes, this 100108432 valve is the current OEM replacement for the obsolete A.O. Smith 9000547005 part number. Always verify the model and serial number of your equipment before installation.
Does this valve include the ignition control module?
This is the mechanical gas control valve only. While it interfaces with the ignition system, the electronic spark or hot surface ignition module is a separate component.
