I keep my intake blower about 1/2 open (where the factory mark is set at). I keep it at .04 with Direct Vent.
Going on 6+ years with it and never had a problem.
Typcially, 4 Turns out is a good starting point for these, then adjust accordingly (1/2 turn in or out). I think I am at 5 turns out and 4 or 5 Pins on the timer every 10 mins.
Question on the feeder... when it's feeding coal and the lobe is rotating mine has lag or some time when the bar is not moving in between pushing and pulling (about 12 or 13 seconds between strokes). Is this normal? I still suspect my cam is worn, because I can have my feed maxed out and turn the thermostat all the way up to feed continuous for hours and still have a good 1.5 to 2 inches of ash at the end of my grate (with restrictor plate at factory 1/2 open). If I were to back the screw out 4 or 5 turns I wouldn't get enough heat for the upstairs.
I did have to replace the nylon screws that adjust the pusher bar to keep it moving straight because they were melted off when I bought the stove, so obviously the previous owner had some sort of problem (the stove was hooked up as direct vent). As I said in one of my posts this is a direct vent stove but I have removed the fan assembly to hook it to my chimney.
