If you are ordering a Coal-trol installed from the factory the settings should come already set to the recommended starting point for that model stove. Many people run just fine with these recommended settings. However, as you get used to the stove and burning coal you may want to see about tweaking things to get the most out of your stove.
The manual that ships with the thermostats has the most up to date recommended settings information in it. The PDFs posted on our site are a bit dated at this point. We're in the process of updating the site with the latest manuals, product line, the new igniter kit, and the rest.
Also, there are many threads here on the forums that go into people's experiences with tweaked settings for various models of stoves.
