The specification discloses a grate replacement kit for a solid fuel burning firebox. The kit includes an extendable grate, adaptable to a variety of different size fireboxes, and a scale to be mounted on the outside of the firebox. Further included is a hinge assembly for pivotally mounting one end of the grate to the firebox with the opposite end of the grate operatively supported by the scale. The scale is responsive to the weight of the grate and any fuel supported thereon to indicate when restoking is required to prevent the fire from burning out. Preferably, a signal device responsive to the scale is included to emit a signal in a location remote from the firebox when additional wood is required.
