Lochinvar L100286123 Outlet Lwco Air Vent Auto

Product Description

The LOCHINVAR L100286123 is a combination outlet assembly integrating a Low Water Cut-Off (LWCO) and an automatic air vent into a single serviceable component. The LWCO function monitors boiler water level and cuts power to the burner when water drops below a safe threshold, protecting the heat exchanger from dry-fire damage. The automatic air vent purges trapped air from the hydronic circuit, maintaining proper flow and heat transfer efficiency. This part is installed by licensed plumbers and hydronic heating technicians during new installations or service replacement work on hot water boilers.

This outlet assembly is suited for residential and light commercial hydronic heating systems where a combined LWCO and air elimination function is required at the boiler outlet connection. It is a direct OEM replacement part sourced from LOCHINVAR and is intended for use in systems where the original equipment calls for this specific assembly. Installers working on LOCHINVAR boiler systems should verify the outlet connection size and thread type before installation to confirm fitment.

Key Features

• Integrated LWCO function shuts down burner on low water conditions, preventing heat exchanger damage
• Automatic air vent eliminates trapped air at the boiler outlet without manual intervention
• OEM replacement part ensures proper fit and function within the original boiler assembly
• Combined assembly reduces connection points and simplifies service replacement
• Designed for hydronic hot water boiler applications in residential and light commercial settings

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician. Before servicing, shut down the boiler, isolate the system pressure, and allow the unit to cool completely before removing the outlet assembly. Follow all applicable local plumbing codes and the boiler manufacturer service documentation when reinstalling or replacing this component. Inspect mating threads and sealing surfaces before torquing the assembly into place.
