The AO SMITH 100112832 is a main burner kit designed for gas water heater systems. The main burner assembly is a core combustion component responsible for generating the heat that warms the water supply in residential and light commercial applications. This kit provides the necessary burner hardware for a direct replacement of a failed or worn burner assembly. Licensed plumbers and HVAC technicians install this part during routine service calls or when diagnosing reduced heating performance or ignition failure in gas-fired water heaters.
This burner kit is suited for gas water heater installations where the original main burner has degraded, been damaged, or failed inspection. It is intended for technicians performing in-field repairs on gas water heater units. The kit format means the required burner components are supplied together, reducing the need to source individual parts separately during a service visit.
Designed as an OEM-style replacement main burner kit for AO SMITH gas water heater systems. Consult the equipment nameplate and AO SMITH 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 appliance manufacturer guidelines. Shut off the gas supply and allow the unit to cool completely before beginning any burner service work. Inspect all gas connections for leaks after reassembly using an approved leak detection solution. Do not restore gas supply until all connections have been verified leak-free and the burner assembly is fully secured.
