during the last couple storms we had, i went to check on the boiler, and draft gauge now that i have the manometer installed and settings tuned to keystokers specs. i noticed that the baro damper sometimes sticks and im over drafting. sometimes quite a bit. damper isnt stuck open, or closed, just not in the right position. not sure if that means the weight isnt set just right? ive done some searching trying to find a electronic damper control set up for a chimney and couldnt come up with anything, just curious to see if anyone has looked into it. i was thinking along the lines of having a set of parameters and a small electric motor could keep the draft in the range? mostly coming up with either open or closed for zone heating in duct work. also, as far as draft goes, what is the range that is acceptable, keystoker says .01-02 when stoker is running. some times over drafting to .06 or more. or am i just over thinking this?
thanks again, paul
