The pipe you see is an adjustable intake. Usually, they are run with the bottom vents closed except for one, and the guys put valves on them and extend them up the side so they are easier to reach. Some guys run 'em with water, but usually they are allowed to drip fat directly on the coals, giving an 'open pit' flavor which some prefer, and some don't. That's the beauty- build it to do what YOU want to do on it!
