Nice job on the installation.
I was curious about the baro when I saw the pictures, then I saw it poking out in the one picture. You are probably aware that fly ash builds up behind the baffle plate by the outlet of the stove. The baro serves 2 purposes on your install, it regulates the draft and you can remove it to get in and vacuum out the fly ash easily.
BTW I had problems with the squirrel cage on the blower, it got loaded with dust and cat/dog fur. I cut a piece of AC filter and placed it under the little cover that holds the screen over the air intake (on top of the screen). It's easy to keep clean with a vacuum.
I also see that you have the same problem that I have with wires, I have to have them all coiled up neatly and cable tied as well. I moved a lot of stuff around at my desk and all the PC wires are askew...makes me nuts, I ran out of cable ties.
About that snow falling in your house.....
