Patent ID: 7481650

Claim:
A gas-fired burner assembly, comprising: a burner manifold including a pair of shoulders defining a trough therebetween; a gas conduit disposed within the manifold and linked to the trough by a plurality of gas ports that transport gas from the conduit to the trough; at least one air port provided in each shoulder, each air port linking the trough to ambient air to transport air into the trough, each air port being located substantially between each of the plurality of gas ports so as to form an air buffer between each gas port; a pair of baffles, each baffle comprising a plurality of rows of apertures, fastened to the shoulders, and extending away from the trough in substantially a V-shape defining a combustion chamber therebetween; the plurality of rows divided into at least a primary group of rows; the primary group of rows comprising a first row of apertures and a second row of apertures disposed further from the trough than the first row of apertures; the first row of apertures including a plurality of aperture pairs, each pair being aligned directly above a corresponding air port, thereby forming an air buffer between the gas ports; and the second row of apertures including a plurality of aperture triads, each triad having a center aperture aligned directly above a corresponding air port and apertures to either side of the central aperture aligned with one of the apertures of one of the aperture pairs, thereby forming an air buffer between the gas ports and creating a negative pressure zone above the air ports.
