I am in my second year with my cape cod insert so I am still learning. Untill i found this site few months ago I had no idea about temperatures secondary burns wood moisture etc. I still don't have IR so I don't measure my stove temp, but here is what I am trying to aim for. Get the wood charte and stove hot enough to keep flames going with the air supply shot off completly. I shut my dumper when my fan kicks on(cold start) or when I get all my wood ignited (reload). I am going to get IR over the weekend. But for the time being is that what I should be doing?
