I recently acquired an EPA certified Buck stove model 91 manufactured in May 1992. The previous owner did not realize it was a catalytic stove so I can reasonably assume that the catalyst has not been changed in several years. It was also a slammer in stone. Install. He says it warmed the house very well. I plan to have it installed with a full chimney liner, but I'm wondering if I can run it for this season without the cat. I figure I will have to watch my burn days as it will probably produce too much smoke, I guess my real question is can the stove be restored to EPA conditions when I replace the cat.Included photos of the exterior and top of the unit, the interior and area above the heat shield that I know also has to be replaced. I welcome and appreciate any comments suggestions or ideas.
