I just got my first Intrepid @ hooked up, im burning very dry red oak, i wait until its about 500 degrees and then throw the lever to engage the catalyst and i get more smoke out of the chimney- normal? or do i need a new cat? i looked at the one i had in there and it appeared ok but i am unsure how to really test it. this video below is with the stove running 550+ degrees on a good bed of coals, and red oak, cat engaged.
