Does anyone have an idea of the value, if any of this insert? Sell it or scrap it? It came with the house, installed in the basement fireplace. It looked hardly used by the previous owner & I only had it fired up 3-4 times, for a day or 2 at a time over the past 14 years, when the outside temps dropped to around 0. I'm shopping for a replacement for my old reliable Appalachian 52 main heat source upstairs, and am going to move it to the basement for backup heat, so the Matherly has to go. I can't find any info on this brand anywhere. .
