ABSTRACT:
A tray has an upturned flange at least on the front edge thereof, and support means to space the tray above the floor of a fireplace, such that an opening is provided under the front of the tray to permit air flow. A hollow, raised portion in the tray, or draft control, has orifices that permit a controlled flow of air to fuel in the tray. The tray is closely fitted to the walls of a fireplace; so that, substantially, the only source of oxygen for the fuel in the grate is through the orifices in the draft control. In a preferred embodiment, the draft control is removable and fits over an opening in the tray. Also, valve means may be included for closing the draft control to any desired extent.
