Lochinvar & A.O. Smith 100112706 Valve Kit

When you're troubleshooting ignition failures or unstable burner cycles on a Lochinvar or A.O. Smith natural gas water heater, the 100112706 Natural Gas Valve Kit is the industry-standard OEM replacement required to restore precise fuel regulation. This kit is a direct-fit gas control valve assembly, engineered specifically for high-efficiency water heaters and boilers. It features a 2-inch cavity and is calibrated for a 4" W.C. manifold pressure to ensure stoichiometric combustion and prevent soot accumulation on the radial fire burner. As a veteran-grade HVAC replacement part, it handles the critical tasks of safety shut-off and thermal regulation within the gas-fueled heating system. The 100112706 provides the fuel regulation accuracy needed to eliminate pilot outages and "no hot water" service calls. This hot water heater valve kit is a complete solution, including the necessary gaskets and hardware for a leak-free installation on compatible residential and commercial units.

• Precise Pressure Regulation: Factory-set for 4" W.C. to maintain optimal manifold pressure for natural gas configurations.
• OEM Compatibility: Seamlessly integrates with Lochinvar and A.O. Smith water heaters, ensuring exact port alignment and electrical connectivity.
• Enhanced Safety: Features an integrated safety shut-off mechanism to prevent gas leaks during flame failure.
• Improved Thermal Efficiency: Modern internal diaphragm design minimizes pressure drops, supporting consistent burner performance.
• Complete Replacement Kit: Includes the natural gas valve and essential components for a fast, professional-grade swap-out.

Is this valve compatible with Propane (LP) units?
No, the 100112706 is specifically engineered and calibrated for Natural Gas applications only. Using this in an LP system would cause hazardous combustion levels due to the different pressure requirements.

Does this kit resolve "Pilot Will Not Stay Lit" errors?
Yes, if the internal electromagnet or thermopile circuit within the existing gas valve has failed, this replacement kit will restore the holding current and maintain the pilot flame.

What are the primary symptoms of a failing 100112706 valve?
Technicians typically look for erratic manifold pressure, intermittent main burner ignition, or hard lockouts associated with gas flow restrictions or internal solenoid failures.
