For being Totally Lost, you certainly wound up in the right place...
Since you are new to using a stove, probably the first line of business would be to look it over good. Check for cracks and gaps. Do an inspection of the flue pipe and chimney. Make sure there are no blockages. Look for holes in the flue pipe, determine that its in good condition. The flue pipe may have a manual or barometric damper. Check that they appear in good working order.
If everything looks good, go to the next step. Open the manual damper. Ignite some small pieces of card board to determine if you have some draft. It may leak a little smoke until draft gets going up the chimney..
Since you are new to stoves, I suggest running a couple small wood fires to get familiar with operating the combustion air controls and attempting to control the burn.
After you have that much under your belt, we can guide you into trying some coal..
One step at time..
