ABSTRACT:
A gas burner for gas fireplaces has a housing defining a shallow chamber with an extended top and surface which covers most of the grate area of a gas fireplace and supports non-combustible logs and embers. The chamber has an opening receiving gas or a mixture of gas and primary air, which is discharged through areas of perforations formed in a top wall of the chamber, these areas including both relatively broader and relatively narrower and elongated areas irregularly distributed and oriented over the top wall to provide flames between the logs and to render the embers incandescent, with the areas connected or adjacent to promote the spread of flame between them during ignition. The top wall may be formed by laminating two metal sheets, one perforated and the other formed with slots and holes defining the perforated areas.
