If your hopper started out full and If your ash bin was full with unburned it's because the motor was kicking on and frequently to get that much in a day.
If the temperature in the ash was going down and the sv is set high and the difference between your high and low is small then it's short cycling and just a small amount of blowing is cooling enough to hit the sv-hysterisis and causing you to dump coal before its burned, if this happens too frequently then your hopper ends up empty and your bin full of unburned.
If you have a high and a low wired up then i would try to tweaked them so the the blower goes on when the water temp reaches 160F and shuts off around 180F and turn the sv down to 120F when it's 50-60 outside.
Try to get 2-4 in of WC in a manometer without the blower and 4-6 in with the blower on.
Make sure the baro damper is maintaining the 2-4 and if you have high wind it opens up.
Make sure you have ample combustion air supply especially in a well sealed house so you don't have negative pressure and end up with gases in your house.
If you have whole house fan or bath room fans make sure when you turn those and if you forget one on it's sucking air down your chimney.
Set up some CO detectors also.
I have 3 combination CO and fire detectors, with one in my boiler room, one at the top of the stairs from my basement to my kitchen, and one in the hallway to the bedrooms.
My manometer reads between 0.02" and 0.04", and the baro damper opens to pretty much hold it at 0.04". It seems to read in the same general range with the blower on or off as I recall. I'll have to pay more attention here.
At present I have the boiler room opened up to my adjacent basement for supply air. I'm planning to get an outside air supply set-up installed at some point. I don't think my house is too tight.
