I took advantage of the warm weather and snow free roof to clean my flue this morning. all went well, got out about a gallon and a half of fine grainy creosote. But as has been said on this form many times the trouble will be found at the top, and that was where I found it. Up on removing the cap I found a cone of creosote blocking about half of the 6" liner. It was thin light weight and flakie and fell to the bottom as soon as I touched it. I had noticed the stove was not drawing quite as well as usual so I was not surprised.
