The AO SMITH 100187883 is a burner kit designed for use in AO Smith water heaters. The burner assembly is a core combustion component responsible for generating the heat that warms the water in a storage-type or tankless gas water heater. This kit provides the necessary parts to restore proper burner function during a service call or scheduled maintenance. Licensed plumbers and gas service technicians are the typical installers for this type of repair component.
This burner kit is suited for gas-fired water heater applications where the existing burner assembly has failed or is showing signs of wear, incomplete combustion, or ignition issues. It is intended for use in residential or light commercial water heating systems that use natural gas or propane as the fuel source, depending on the specific configuration of the installed unit.
Designed as an OEM-style replacement burner kit for AO Smith gas water heaters. Consult the unit's model and serial number data plate and AO Smith's parts documentation to confirm fitment before installation.
Installation should be performed by a licensed plumber or qualified gas appliance technician in accordance with local codes and the manufacturer's service documentation. Shut off the gas supply and disconnect power to the water heater before beginning any burner service work. Allow the unit to cool fully before removing burner components. All gas connections must be leak-tested after reassembly prior to returning the unit to service.
