I used this smoker 5 times and finally figured out why the temperture is not hot enough. THE WATER PAN IS TOO BIG. After trying everything under the sun, I open the bottom door and pulled the water pan out a couple inches. Quickly the temp shot up !.. The water pan is blocking the heat. Yesterday I was finally able to smoke at 250F and the propane wasnt up all the way, by keeping the bottom door open and the water pan pulled out about 1/2". Going to call the manufacture today and see what they say. Worst comes to worst, I'll cut some of the flange off to allow the heat to pass by with the door closed.
