There's your answer right there, that wood is way to wet, and will cause coaling. Keep a close eye on your chimney as well for creosote buildup, just read another thread about a guy burning unseasoned wood and his chimney was horrible.
Uh, I didn't buy that wood. But, some of the wood I am burning is almost as bad.
I climbed up top last week and looked down the chimney, and all looks good. Only thing on the inside of the pipe was a fine soot, kind of like the soot that gets on the inside of the globe of an oil lamp if you turn the flame up too high.
