Bingo, key word is THEY, just another revenue stream for them, buy our stove and ohh yea, you have to buy our adapter to.
Actually probably more a case of making it available for folks that have six inch flues as well as all of those people with older cat stoves that have eight inch flues for them. And since they didn't have to change the design of the stove they probably saved the cost of going back through the EPA certification mill. Personally I applaud the approach.
