Stove is drafting very hard, and basement is cooler than last week even though the stove is putting out more. The damn head is going crazy trying to figure this out. Look at the photo I posted and you will see the stove pipe entering the flue above the fireplace. I noticed when I went down stairs to have a smoke and opened the brass doors to the fireplace and the damper to the fireplace the draft according to the manometer would settle back to -.04...-.06 and the baro. settled back to bouncing and not doing a george jetson.
... if the coal stove and the fireplace are sharing the same flu ( as you indicated they are)...
then when you open the fireplace doors and flu damper for the fireplace.. you are effectively creating a huge and out of control barometric damper.... which basically takes your barometric damper out of the equation.. as you noticed.... as like you stated..." it settles down"
.. the pathway created by the fireplace is a head of your barometric damper..
your fireplace doors and damper must seal pretty well... otherwise yourbaro would not work well... if at all
