Ao Smith 100110754 Natural Gas Burner Assembly Kit 32 Orifice

Product Description

The AO SMITH 100110754 is a natural gas final burner assembly kit designed for residential and light commercial water heating applications. This kit includes a 32-orifice burner assembly, providing the combustion hardware needed to restore proper heating function to a gas-fired water heater. It is an OEM-replacement component intended for installation by licensed plumbers or qualified gas appliance technicians. The assembly delivers consistent gas flow and ignition across all 32 orifices, supporting reliable burner performance and efficient heat transfer to the water storage tank.

This burner assembly kit is used in natural gas water heater systems where the original burner has failed, corroded, or requires replacement as part of a broader combustion section service. Typical install scenarios include units that have experienced burner degradation, uneven flame patterns, or ignition failure. The kit is suited for heating applications and is matched to natural gas fuel supply systems operating on standard residential or light commercial gas service.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas appliance technician in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply valve and allow the appliance to cool completely before beginning any burner service. Verify the gas supply type matches the kit rating — this assembly is configured for natural gas only. After installation, perform a leak test on all gas connections using an approved leak detection solution before restoring power or relighting the pilot.
