I have a Dutchwest India Federal Airtight 224 CCL which I have posted about before but have a new question---the instruction manual, which I believe is original (the stove was here when I bought the house) says it is for models built between July 1988 and June 1992 (which is why I did not put this post in the pre-1988 forum) and it has an EPA approval. The manual instructions for opening and closing the various air intakes includes a "bypass gate". There is no picture and I am confused of what this is. I have what I believe is a flue damper. It is a metal plate that closes horizontally to cut off air supply to the stove pipe. I am sure that when this is closed and my two intake air valves (over and under) are closed it is airtight and the catalytic converter maintains a temp of 800-1000 degrees pretty regularly.
So I am puzzled about this bypass gate--am I missing something that might help it burn more efficiently?
