Ao Smith 100111162 Burner Assembly BT80 Upgrade

Product Description

The AO SMITH 100111162 is a replacement burner assembly designed for the BT80 Upgrade Series water heater platform. The burner assembly is the core combustion component in a gas water heater, responsible for igniting and sustaining the flame that transfers heat to the water tank. This OEM-style replacement restores proper combustion performance in units where the original burner has failed, corroded, or become damaged. Licensed plumbers and HVAC technicians handling gas appliance service are the primary installers of this component.

This burner assembly is intended for use in the AO SMITH BT80 Upgrade Series gas water heaters. It is suited for residential or light commercial installations where the BT80 platform is deployed. When a water heater exhibits symptoms such as failure to ignite, uneven flame pattern, or repeated burner lockout, replacing the burner assembly is a standard diagnostic step following gas valve and thermocouple verification.

Confirm the replacement assembly matches the original burner configuration before removing existing components.
