So after burning four cords of wood so far, I finally climbed up on the roof to take a look down the chimney. First look at the cap showed it was covered in a thin coat of a hard black candy shell of creosote, I was thinking oh $#!+. So I took off the cap and looked down, the chimney had less than a 1/4" layer of fine airy stuff that broke into coffee ground type pieces. I started cutting my wood supply last April, and the last cord I burned wasn't split until July, so I know my wood did not get the optimum drying time. Is that a reasonable amount to have in the chimney after four cords, considering the seasoning time of the wood? I'm thinking with the black chimney cap, I must have went through more than a few charges of not so dry wood.
