Buck1949, you have the DB on the heat shield you have cut the notches another 1" wider so you can slide the heat shield over the fire pit want to make sure your fire out of the fire pit is hitting dead center on the inverted V" under the heat shield, make sure you have your 2 piece drip tray in the closed position only have it opened if your searing meats or cooking over 400 degrees. Feel free to ask me any questions I'll do my best to answer them and help you in any way possible.
