Feeling the Heat
Reading most of these threads, you can get the idea that cats are difficult and fiddly but that noncats are hands off. But even with a non cat like ours, you do have to watch it and you should have a stove top thermometer and a flue thermometer and you still have to control the air. If you aren't careful, you can have problems like overfiring, backpuffing, creosote buildup, etc.
I would like to add that the downdraft style non-cats are especially finicky. Not only from my personal experience but also from what I've read.
