new to the forum here, so please correct/instruct me were needed. bought a pretty rough shape 2462 three years ago and had it sand blasted, repainted, replaced the cat gaskets and it was amazing for two years. had issues with the the cat not reaching temp at the end of last winter, so i suspected i needed a new cat (first cat was cheap, probably from china). So the cat was pretty blown out and i replaced it with a midwest heart cat, and did some recaulking where i saw cement was gone and tryed to tighten up the stove. The cat worked but now i have an issue when it reaches 1200-1300 degrees it back puffs smoke. i have tried to watch it and it seems to be coming along the side door front panel seem. The door seems to be good and tight with new gaskets. I love this stove but the smoke is giving us headaches thru the night and i have been just burning the stove without the cat engaged.
