Ao Smith 100109221 Piezo Igniter with Bracket

Product Description

The AO SMITH 100109221 is a piezo igniter with mounting bracket designed for heating equipment. A piezo igniter generates a high-voltage spark through mechanical compression, eliminating the need for a separate ignition power source. This assembly includes the bracket for direct mounting, simplifying installation and replacement. Licensed heating technicians and plumbers install this component during burner service or igniter replacement on water heating and heating appliance applications where spark ignition is specified.

The 100109221 is intended for heating applications where a piezo-type spark igniter is required. It is suited for residential and light commercial heating equipment service. The included mounting bracket ensures the igniter is positioned correctly relative to the burner assembly, maintaining proper spark gap and reliable ignition performance.
