What is a Beckett oil transformer and where is it used in heating systems?

In heating systems, “Beckett oil transformer” usually refers to the ignition transformer used with Beckett oil burners. Its job is to produce a high voltage output to create a spark at the burner electrodes, igniting the oil air mixture during start up. It is used in residential and light commercial oil fired furnaces and boilers that use Beckett burner assemblies. Correct selection depends on required secondary voltage, current, mounting, and duty cycle specified for the burner model.
