The LOCHINVAR L100268031 is a gas valve assembly designed for use in hydronic heating and water heating equipment manufactured by Lochinvar. The gas valve assembly controls the flow of gas to the burner, regulating ignition and combustion within the appliance. This component is a direct replacement part intended for installation by licensed plumbers, HVAC technicians, or gas appliance service professionals who work on Lochinvar heating systems.
This gas valve assembly is suited for residential and light commercial applications where Lochinvar boilers or water heaters are installed. It fits into the gas train of the appliance and is a critical safety and control component. Technicians typically encounter this part during routine maintenance, combustion troubleshooting, or after diagnosing a failed valve through pressure testing or error code review on the appliance control board.
Designed as an OEM-style replacement gas valve assembly for Lochinvar boilers and water heating appliances. Verify fitment against your specific model and serial number before ordering.
Installation must be performed by a licensed HVAC technician, plumber, or gas service professional in accordance with local codes and the appliance manufacturer guidelines. Shut off the gas supply at the service valve and disconnect electrical power to the appliance before beginning any work on the gas valve. Confirm proper valve orientation, inlet and outlet connections, and electrical harness routing before restoring gas and power. After installation, perform a leak test on all gas connections using an approved leak-detection solution before returning the appliance to service.
