I was skeptical but undecided when I saw the post from the guy who claimed he found nails in his stove - until tonight. When I got home tonight my significant other was cleaning out the stove. He was in another room when he said he heard a binding metal-to-metal sound from the stove - then he heard a snap when the it obviously would become free - he described it as clingity/clang then booming sound. When it snapped the stove would jump. The drive motor for the auger did stop. After some investigation he found the nail in the bottom of the auger slot. Having worked in manufacturing he identified the nail as a pallet nail. So...I guess the lesson learned is to monitor your pellets because they are obviously recycling pallets which results in nails getting through. I wonder how many of the problems posted on this site were caused by nails in pellets?
