I did receive an 18" WSM for Christmas. I rubbed it down with oil and ran a load of charcoal and apple chips wor 4 hours at 300+ degrees. I wasn't sure what to do so I out water in the pan. 1) Do you always use the water pan? Do you ever leave it out or leave it empty of water? Is it more to add moisture or to control the temperature? I have read both. 2) Which grate it hotter, top or bottom? Is there a guide for placement of different cuts of meat? 3) not really a WSM question but I also received one of those coal starter cans. I started it by balling up newspaper and stuffing it underneath. Any other ideas? I have an electric starter but the instructions on the can say not to use it.
