Being new on the block to coal burning I talked to a guy the other day about his coal stove operation and if he was pleased with it overall. He told me he was and that he has only had one problem that occured 2 times during the winter. He said that on these 2 occasions that coal had stuck to the side of the hopper and formed a plug therefore no coal feeding to the auger feed mechanisim. He said he pounded the side of the hopper loosening the coal but that it rushed down the feeder onto the fire and put the coal fire out.
Does this happen on occasions and if so is there something that can be put on the inside of the hopper to prevent this?
