Abstract
An ignition system for igniting a gas burner of an appliance includes a gas burner, an electric igniter assembly, a pilot light, and a controller. The pilot light is ignitable by the electric igniter assembly. The controller is configured to operate the electric igniter assembly for ignition of the gas burner, detect a power disruption event, ignite the pilot light using the electric igniter assembly in response to detecting the power disruption event, and use the pilot light for ignition of the gas burner during the power disruption event. Methods of operating the ignition system for igniting the gas burner of the appliance are also provided.
