Lochinvar L100112679 Hot Surface Ignitor

Product Description

The LOCHINVAR L100112679 is a hot surface ignitor designed as a direct replacement component for gas-fired heating systems. Hot surface ignitors generate the high heat required to ignite the main gas burner without a standing pilot, making them a critical part of modern residential and light commercial heating equipment. This ignitor is installed by licensed HVAC technicians and plumbers servicing gas appliance systems. Its solid-state design eliminates the reliability concerns associated with older spark ignition systems and provides consistent ignition performance across heating cycles.

Hot surface ignitors of this type are commonly found in gas-fired boilers and water heaters where reliable burner ignition is essential. The L100112679 is suited for installation in residential and light commercial applications. Technicians replacing a failed ignitor will find this part appropriate for systems that originally specified a compatible HSI component. Refer to the original equipment documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional. Shut off gas supply and disconnect electrical power to the appliance before removing the existing ignitor. Hot surface ignitors are fragile ceramic or silicon nitride components — handle only by the lead wires or mounting bracket and avoid contact with the ignitor element itself, as skin oils can cause premature failure. Follow all applicable local codes and the manufacturer service documentation during replacement.
