I finally finished the install yesterday and I could not be happier! What a nice burning stove, stays right around 400 stove top with very little effort and there were plenty of coals to keep it going this morning. The liner install was no picnic at all and I wouldn't try it again under the conditions I have. My existing flue is approximately 6.5 x 11 and has 2 corbels in it, about 25' high, ending at a fireplace in my semi finished basement. I knew I'd never get a 6" liner down there so I went with a 5" liner and even that was a bear to get in. I was really hoping to snake right through the existing damper without destroying it but in the end I had to cut part of it out and chip out a few brick from the back of the fireplace. But, it's done and I'm happy, nice strong draft and very little visible smoke when it's cruising.
