i have been reading this forum for the last few days, and i have found it to be very informative. in a previous post i seen someone mention that the draft control knobs will spin a full 4 turns. mine do not. on one door it will turn 2 full turns, the other 2 and 1/4 turns. this does not seem to be enough. in order to keep the flue pipe temp over 300 degrees i must keep them wide open. i took out the allen screw and found the washer is welded on . so in other words if i could unscrew the knob more it wouldnt increase air flow. this stove was purchased in may of 1984 if that helps any. when i purchased this stove 4 days ago i was given the original warranty card completly filled out but for some reason was never sent it. any help would be greatly appreciated . thanks, mike.
