After reading a few posts about the 'doghouse' (the vents where primary air enters the stove below the stove door) I was cleaning ash from my stove the other day and lo and behold I found that my stove has a doghouse! I didn't know it was there, but below the ash lip inside the door opening there is a square tube with a single large hole in it apparently to let air into the stove down at coal level. It has been covered with ash for a long time but seems to be working now. It isn't making a huge difference, but it does seem that I am burning up coals a little better than before and it seems like I am setting the air a little lower than I was (although the wierd weather - rain in January? - makes it a little tough to tell). If anyone out there is getting poor draft you might want to make sure your doghouse is clear of ash. Mine is very easily buried and when removing ashes it is easy to miss clearing the doghouse.
