Lochinvar & A.O. Smith 100108352 Valve
When you are in the field servicing commercial water heaters or boilers, you need a replacement gas valve that matches the exact manifold pressure and inlet requirements of the original equipment. The Lochinvar & A.O. Smith 100108352 is a high-performance 1/2 inch natural gas valve engineered to maintain a precise 4" WC output. As a genuine OEM HVAC part, it ensures the burner receives a consistent fuel flow, which is critical for maintaining thermal efficiency in units exceeding 55,000 BTUs. This NG natural gas control valve features a compact design with standard 1/2" NPT connections for a direct fit in Lochinvar boilers and A.O. Smith commercial water heaters. Using an OEM gas valve like the 100108352 prevents the common combustion issues—such as rough starts or nuisance outages—associated with generic regulators that cannot handle the specific diaphragm response needed for these high-efficiency systems.
Key Benefits- Precise Pressure Regulation: Pre-set for 4" WC natural gas to ensure optimal burner firing and flame stability.
- OEM Compatibility: Guaranteed fit for specific Lochinvar and A.O. Smith commercial models, eliminating the need for field modifications.
- Durable Construction: Designed to withstand the rigorous duty cycles of high-output commercial heating applications.
- Efficient Fuel Combustion: Promotes consistent gas-to-air ratios to maximize system efficiency and minimize carbon buildup on the heat exchanger.
Can this valve be used for Propane (LP) conversion?
No, the 100108352 is factory-calibrated for natural gas (NG) at 4" WC. Using it for LP without a manufacturer-approved conversion kit is unsafe and will result in improper manifold pressure.
What are the signs that my current gas valve is failing?
Common indicators include the burner failing to ignite, "booming" during ignition due to delayed gas release, or the unit shutting down because of inconsistent fuel pressure. Always verify with a manometer at the pressure tap before replacing.
Is this a universal 1/2" gas valve?
While the 1/2" NPT threads are standard, the internal spring tension and output pressure are specific to Lochinvar & A.O. Smith requirements. Always match the part number to your specific model and serial number.
