Abstract
Abstract A fireplace insert comprising a frame having a plurality of arms pivotly mounted on the frame. The arms are adapted to move relative to each other in order to form an X-shaped configuration or a V-shaped configuration which will provide spaces to hold logs and/or kindling material. The arms are adjustable on the frame so that the spaces for the logs can be adjusted to accommodate logs of varying sizes. The device permits the logs to remain close to each other and at the same time will provide sufficient air space to form a very efficient fire.
