Abstract
A burner assembly for use in a warm air furnace. The burner assembly has a cooling air box for receiving air and a premix burner for receiving air-fuel premix positioned within and spaced apart from the cooling air box. The burner assembly also has a burner face assembly defining a front end of the premix burner. The burner face assembly includes a first plate positioned on top of a second plate, and a third plate positioned underneath the second plate. Each plate of the burner face assembly has a plurality of aligned burner openings. In the burner assembly, air-fuel premix is pulled through the premix burner, air is pulled through the cooling air box to cool the premix burner, and flames are projected from each of the burner openings of the burner face assembly for transferring heat within the warm air furnace.
