Product Description

The AO SMITH 100223203 is an 18-inch final burner assembly kit designed as a replacement component for water heater systems. This kit includes a 3.5-inch extension and is compatible with 34TP series applications. The burner assembly is a core combustion component responsible for igniting and sustaining the flame that heats water in gas-fired water heaters. Installation is typically performed by licensed plumbers or HVAC technicians during scheduled maintenance or component failure service calls. The 34TP designation indicates a specific burner series configuration relevant to OEM replacement applications.

This burner assembly kit is intended for use as a direct replacement part in residential or light commercial gas water heater systems. It is suited for technicians performing burner replacements due to wear, corrosion, or flame failure. The 34TP series designation and 3.5-inch extension configuration make this kit appropriate for specific AO SMITH water heater models requiring this exact burner geometry and mounting profile. Always verify the full model number of the water heater before ordering to confirm correct fitment.
