I'm about to have my 2461 large cat stove re-built. I recently looked on the tag on the back of the stove, and it says it meets July 1989 emission standards. I know that the first "new" EPA laws went into effect that year. Is this the first model cat stove produced by VC ? I loved this stove,and it really didnt get much use at my parents house. Maybe 15-20 fires a year for the first 10 years, and then no fires for the next 10 years. Did VC make a cat stove before this,or is this the first one made?
