Dave you are right. before i knew more about what to burn and what not to burn.i did burn a lot of oak pallets which were nailed together last year. plus a lot of the kindling i used also had nails. the cat does stay in the active range the whole time though. The new cat will he here monday and i will throw it in..no biggy. im almost positive its the cat. i will take a picture of the flue when i get out of work. i have double wall as well with two 45’s about a 3 foot rise into the chimney then a about 25 feet of a steel liner insulated up to the cat. which i believe is a pretty solid setup. also i have read that woodstove combusteor web page within the last few days. wish i would have read it 2 years ago.
Eco, did you get a steel or ceramic?
