I am rebuilding a Pacific Energy 1997 series D standard wood stove. Had to make new top inside left and right top rails that hold the secondary burn plate. I noticed on this model that the secondary air adjusts with the primary air. When you close down the primary air it also closes down the secondary air. I have not seen this before on the other wood stoves I have worked on. From what I have seen the secondary is always open with no adjustments. I am thinking about disconnecting the secondary air from the primary so it is always open. What are your thoughts?
