Ao Smith 100112348 Burner Assembly

Product Description

The AO SMITH 100112348 is a burner assembly designed as a direct replacement component for gas-fired water heaters. The burner assembly is the core combustion component in a gas water heater, responsible for igniting and sustaining the flame that heats the water supply. This part is installed by licensed plumbers and HVAC technicians during routine maintenance or when the existing burner shows signs of failure such as incomplete combustion, sooting, or failure to ignite. Proper burner function is essential to maintaining rated heating output and safe appliance operation.

This burner assembly is suited for residential gas water heater applications where the original burner has worn or failed. It is intended for use in standard tank-style gas water heaters that rely on a standing pilot or electronic ignition system to initiate combustion at the burner. Installation is performed during a service call when combustion performance has degraded or when a full burner assembly replacement is required as part of a water heater repair.

Key Features

• Direct replacement burner assembly for gas-fired water heater service
• Restores proper combustion performance when original burner fails
• Compatible with tank-style residential gas water heater configurations
• OEM part number ensures fit and function match to original equipment

Compatibility

Designed as an OEM-style replacement burner assembly for AO SMITH gas-fired water heaters. Confirm model number compatibility on the water heater nameplate before ordering.

Installation Notes

Burner assembly replacement should be performed by a licensed plumber or qualified gas appliance technician. Shut off the gas supply valve and allow the appliance to cool completely before beginning disassembly. Follow all local gas codes and manufacturer service procedures when making gas connections. Inspect the thermocouple, pilot assembly, and gas valve for wear during service, as these components interact directly with the burner.
