The 520 is almost done setting up, all the electrical and a draft inducer are some of the final things, I was reading the online manual and trying to understand how to count the teeth settings.
There is the "blue pall" on the left and the other pall on the right. This pall can ride on the "thin curved plate" that is adjusted with the thumbscrew. I understand the moving the thin plate left or right is what makes the teeth change setting.
But can someone explain how to really understand it? Count the number of clicks, but which clicks, the blue or other?
