Last night I went down to check on the furnace, and it was 2-3" of smaller size coals (nearing the end of the cycle). When I stoked it, all the sudden there was this shower of sparks, the sparks were really small not like when say something pops. it was like one of those sparklers on the 4th of july. the wood was a mix of sugar maple and cherry.
What the hell was it?
