I have not measure the draft I don't have the means. I have the manual weighted type of damper. I started the fire on a nice cool day (around 30°F) let it heat up and set the damper to where it just wanted to open up. My exhaust temps where at about 200°. Knowing this was too much I lightened the weight out some more to maintain it around 150°F. The adjustment is just about all of the way out and hangs open about 1/4"-3/8" until the wind blows out side. This seemed to get a little more heat but still not as much as I expected. Still goes through way to much coal in a given day. These settings are with the dial on about 1.5 - 2 and the blower fan on high speed.
You should request to borrow the manometer from the loan program a few of the guys on here are offering. Matthaus is one of the users here that has offered one of his manometers to loan out to folks here that don't have one. It's free and would give some good information. You say you have a manual, weighted damper. I'm not that familar with these, but could you be referring to a barometric damper like this one below?
Also, I'm not sure about this, but it would seem logical (to me) that slower fan speeds may allow the air to pickup more heat off the stove and carry it out into the room. I know with my AC install, I got cooler air temps and less humidty in the air when I reduced the fan speed on my air handler.
Lastly, my friend has a 6 week old Channing III and at high fan speed, the convection fan makes very little noise. More of the sound of air being pushed. At lower speeds it's pretty much silent.
Just something to think about. I agree that if you're burning 100 pounds a day, you should be getting some serious heat off that thing. I assume the basement doesn't have doors/windows open (thats a joke)
