Can I get a good answer, Thermostat question?

You are correct Step, in the youtube video he is not installing the rubber seal as designed. The seal is supposed to be installed like a grommet around the flange of the thermostat (as you describe).

I believe the "hat" portion faces the shorter portion of the thermostat, but I will have to confirm that when I replace mine this Spring. The images on the internet are all over the place and are pretty useless.
