fresno,
Sometimes we use chips to help light the charcoal in our brinkman because they do flame easily if the air gets to them. All we use now for smoking is either chunks or sometimes whole pecans. Citrus wood is great and in your area might be easy to get. They say to let it dry first before using in the cookshack. On a brinkman you can use it as green wood, the moisture you put in the water pan is partly reduced by the water in the wood. I'd follow the directions to dry first, especially if using your nice new cookshack!
