That's fine if you don't burn on windy days.
Also I'm not sure how accurate and effective a baro is, if it is mounted some distance from the flue. Notice that the Field Controls baro comes with a kit that makes a very short tee to mount the baro very close to the gas flow within the flue. Even putting it in a standard 6-inch tee is not optimal, though probably adequate for something as crude as a coal stove. And the weight calibration scale on the baro is slightly different for mounting on a horizontal vs. vertical section of the flue -- which again says the baro should be very close to the flow of flue gas, not several feet away on an extension that passes through the wall, 'cause then how would it know?
Meeting part way is not good enough. I need to WIN!
Seriously, the baro needs to be in the same room with the stove, at the same air pressure as the stove. Nothing else will do. (Unless I'm full of shyt, which might be true but I'm not comfortable with that notion.
