Lochinvar L100340123 Ignitor with Gasket

Product Description

The Lochinvar L100340123 is a replacement ignitor with gasket designed for use in Lochinvar heating equipment. The ignitor initiates combustion by providing the spark or hot-surface ignition required to light the burner assembly. It ships with a mating gasket to ensure a proper seal at the mounting point, preventing flue gas leakage and maintaining combustion efficiency. This component is installed by licensed HVAC technicians and plumbers servicing Lochinvar boilers and water heaters.

This ignitor with gasket is suited for residential and light commercial Lochinvar heating systems where the original ignitor has failed, shows visible damage, or has reached the end of its service life. Replacing the ignitor as a complete assembly with the included gasket reduces the chance of callbacks caused by improper sealing at the ignitor port.

Key Features

• Replacement ignitor matched to Lochinvar OEM specifications
• Includes mating gasket for a sealed installation at the burner assembly
• Direct OEM-style fit reduces modification and installation time
• Suitable for both boiler and water heater applications in Lochinvar equipment

Compatibility

Designed as an OEM-style replacement ignitor for Lochinvar heating equipment. Consult the equipment model number and service documentation to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with gas-fired heating equipment. Shut off the gas supply and disconnect electrical power to the unit before removing the existing ignitor. Always install the included gasket when seating the new ignitor to maintain a proper combustion seal. Refer to the equipment service manual and applicable local codes for torque and wiring requirements.
