Abstract

A relighter apparatus for operating a pilot burner for a fuel pipeline heater. The relighter apparatus has a controller located at a first location, and a pilot burner assembly and ignition coil located at a second location which is remotely located a distance from the first location. The ignition coil is also electrically connected to the controller. The ignition coil receives a low voltage input based on a signal from the controller and provides a high voltage output at the output thereof. Current corresponding to the high voltage output is transferred from the ignitor coil, through a terminal and to an ignitor rod. A conduction of the electrical current between the second end of the ignitor rod and the pilot burner assembly causes an adequate spark to ignite the air/fuel mixture in the pilot burner assembly, creating a pilot flame.
