Lochinvar & A.O. Smith 100278055 Valve

The Lochinvar & A.O. Smith 100278055 Valve is a critical replacement component designed for high-efficiency liquid propane (LP) heating applications. Engineered for precision gas flow regulation, this 24V LP gas valve operates at a standard 10" WC manifold pressure, ensuring stable combustion and optimal thermal efficiency in compatible boiler and water heater models. As a genuine OEM Lochinvar gas valve, it features a 3/4" NPT inlet and a 1/2" NPT outlet, facilitating a direct fit for contractors performing a gas valve replacement on residential or light commercial units. This 100278055 part is specifically calibrated for LP systems and should be verified against the appliance's serial and model 100278055 requirements to maintain safe operating parameters. When troubleshooting ignition cycles or flame failure faults, this low voltage gas control provides the reliability seasoned technicians expect from A.O. Smith manufacturing. Proper installation requires technical expertise to ensure leak-free 3/4"x1/2" connections and accurate manifold pressure settings at 10 inches water column.

Key Benefits
  • OEM Compatibility: Precision-matched for Lochinvar and A.O. Smith equipment, ensuring seamless integration with existing 24V control circuits.
  • Technical Specifications: Pre-set for 10" WC LP applications with a versatile 3/4" x 1/2" port configuration to suit standard gas train layouts.
  • Enhanced Reliability: Heavy-duty internal solenoids provide consistent opening and closing cycles for reliable burner ignition.
  • Safety Compliance: Designed to meet rigorous thermal and pressure standards for liquid propane combustion systems.
Common Questions
  • Can this valve be converted for use with Natural Gas? No, the 100278055 is specifically calibrated for Liquid Propane (LP) at 10" WC. Using it with Natural Gas without proper conversion components may lead to hazardous operation.
  • Will this fix an ignition lockout on my Lochinvar boiler? While a failing gas valve is a common cause of ignition lockout, technicians should also verify spark electrodes, flame sensors, and 24V signal arrival at the valve before replacement.
  • Does this valve include the LP conversion kit? This model is an LP-specific valve. If you are converting from Natural Gas, ensure all other orifices and manifold settings are adjusted per the manufacturer's technical manual.
