A bit late to the party (I was out of town for about a week).
Congrats on the KK purchase. You will never regret it.
Like others have said, just be a bit patient and learn your grill. Set up a chair with your favorite adult beverage, light a basket of lump charcoal (I'm a MAPP torch guy), and slowly open the top and bottom vents to learn how your KK responds to different settings. Keep good notes (depends on how many adult beverages you have!) And, most importantly, don't be afraid/embarrassed to ask questions here!!! We all had to learn this stuff at one time or another. Take advantage of the years of experience here to guide you along the way. Lots of great advice in the archives of the Forum, too. Use the search engine - it's a great tool.
Happy trails, YTB.
