We have a older Century S131e stove and we use it to primarily heat the house. We are ending up with a large amount of hot coals after a few hours of burning. We are staying in the green on our temp gauge constantly now and we got a moisture meter and it's been reading about 10% when I check the wood. We get so many coals, it gets to the point we can't add more wood with out the coals spilling out. Are we doing something wrong or we will just have to clean the coals out every few hours?
