ABSTRACT:
A premix gas burner has a flat, composite burner plate formed by a rear flat plate having a first set of apertures and a forward flat and thinner plate having a second set of apertures of less diameter than the first set of apertures. The plates are connected to form a composite burner plate at the front end of a burner tube. A pilot tube extends through the burner tube and a pilot flame ignitor includes an insulated center electrode and a spirally wrapped grounding electrode electrically engaging the I.P. of the pilot tube to form an electrical ground. The electrodes spark to ignite a pilot flame which in turn ignites the larger burner flame.
