It is easier that most people realize.
Two things that I did not see posted
1. Depending on your flue (I have a cast iron flue in my Isokern) you may be able to clip an S hook and a length of chain to hang dutch ovens. I have found that helps to be able to slide the pot closer to fire if needed.
2. Try screwing a screw-eye into your ceiling and suspend a chicken on a string. Dont forget a pan for drippings. spin the chicken every 10 minutes or so and keep a hot fire.
