Here is a pleasant update to the stove temp compared to the stack temp.
I finally broke down and forked over another $14 to buy a thermometer that matches the one on the stove. The one previously installed on the stack was from the wood burner that was ripped out to make room for the Harman. I can't believe the difference.
As it is today, the wind is light, outside temps in the low 40's, and the Harman is churning at 350 degrees since 700AM. I am proud to announce my ACCURATE
stack temp is 140 degrees, not the 250 as previously thought. I even went as far as to swap the matching thermometers and the readings matched... 350 stove / 140 stack.
So, please disregard the information below and please comment if these readings are more inline with a proper install. Of course, I have not needed to crank up the stove temp so far today. I would imagine the stack temp may go up somewhat when the stove temp hits 475-550 on a real cold day.

I installed another thermo on the stack in addition to the one on the side of the Harman. Keep in mind I never got a manometer to check draft.
I can idle the Harman Mk II at 3/4 turn of the damper and stove temp is 275-300, but the stack temp is 250.
If I run the damper at 1 turn the stove temp ranges 300-375, but the stack temp stays at 250.
At 1 1/4 turns stove temp ranges 375-450, and the stack temp climbs to 275.
At 1 1/2 turns stove temp 475-550 and the stack stays at 275.
If I went 1 3/4 to 2 turns the stove temp get to 600 and can creep over 600. The stack temp stays at 275, but I REALLY DON'T feel comfortable burning that hot.
Based upon stove temp to stack temp, does it seem like I may have a decent setup so far? I have not tested the stove for any period of time burning from cracked open to 1/2 turn on the draft.
