The AO SMITH 100110898 is a burner gasket designed as a direct replacement component for water heater and boiler heating systems. Burner gaskets form a sealed interface between the burner assembly and the combustion chamber, preventing flue gas leaks and maintaining combustion efficiency. This part is intended for service and maintenance applications where the original gasket has degraded, cracked, or failed. Licensed plumbers, HVAC technicians, and heating system service professionals typically handle this replacement as part of a scheduled maintenance or emergency repair call.
This burner gasket is suited for heating applications requiring an OEM-style replacement part. It is used when servicing the burner assembly on applicable AO SMITH units, typically encountered in residential and light commercial water heating or boiler installations. Proper gasket condition is critical to safe combustion and preventing dangerous flue gas migration into occupied spaces.
Designed as an OEM-style replacement burner gasket for AO SMITH heating equipment. Consult the unit service manual or AO SMITH parts documentation to confirm fitment for a specific model before installation.
This part is typically installed by a licensed plumber or HVAC technician during burner assembly service. Shut off all fuel supply and electrical power to the unit before beginning disassembly. Ensure the combustion chamber has fully cooled before handling any burner components. Verify the replacement gasket seats evenly and completely before restoring fuel and power.
