I highly suspect you may have moist wood. If the car isn't cracked or has holes in it it's still good imo. It is warmer right now and the stove with a short stack and moist wood is going to backpuff and stall the cat in not time...from 5 years experience. I have a 25 foot internal stack and the stove runs well right now....but still I don't run the stove except at night when the temps dip below 35. Stove runs very poorly above 40 degrees even with my tall chimney.I haven't decided if I like this stove or not. Right now I'm having issues getting the secondary to light. It's pretty hit or miss. It will light and run for a while, and then it seems to go out later and I have back puffing problems. I've never used a stove with a cat before. I'm wondering if the cat needs replacing.
