ABSTRACT:
A device and method for extending the burning time of wax synthetic logs and for reducing the amount of smoke, odor and residue. The device comprises a sloping tray having a lower edge facing the front of the fireplace and an upper edge toward the rear of the fireplace, a first upper flange along the upper edge of the tray to deflect air around toward the ends and front of the log, and a second lower flange along the lower edge of the tray. A log is placed on the sloping tray with its axis parallel to the flange, and ignited in the normal manner. The second flange, in addition to preventing the log from rolling forward, defines a region into which molten wax from the combustion of the log flows to form a reservoir and provides an air space above the surface of the molten wax such that air deflected by the first flange enters the air space to promote burning along the front and top portions of the log. A lip on the lower flange further defines the reservoir and air space.
