Claim 19:
20. A method of reducing noise in a burner assembly comprising the steps of:
positioning an air fuel mixing tube relative to a mixing tube opening in a burner box to create at least a portion of a Helmholtz Resonator;
locating a baffle within the burner box to create an enclosure at least partially separating the mixing tube opening from a burner plate opening in the burner box;
separating an incoming air-fuel mixture into at least two opposing flow paths that flow around the baffle to the burner plate opening; and
varying a position of the baffle within the burner box to vary a length of an enclosure at least partially defined by the burner box and a back wall of the burner box to extend the Helmholtz Resonator and vary a resonant frequency.
