On V3 and V4 version of the thermostat our suggested starting points for Reading (non-triburn) settings are: MIN 4, MAX 24. As for the combustion air, you may want to dampen it down a little bit. If you get clinkers or see that even at MAX fire the burn line isn't getting to within an inch or so of the end of the grate you are probably burning too hot and need to dampen the air flow some more.
If you intend to burn it now and are using a natural draft chimney, you may find you need to use a higher MIN setting in order to maintain proper draft. If you're using a power venter, then MIN 4 should be fine.
