This easy-to-use, LP gas vertical smoker, is the perfect solution for year-round backyard cooking. It all starts with a push button, electronic ignition that emits a rapid pulse for quick and easy lighting. The 15,000 BTU, cast iron burner maintains constant temperature for reliable cooking performance  in cold or warm weather. The double door design helps minimize reduction in cooking temperature when access to food is needed or when more water and wood chips are added. 4 height adjustable cooking grates provide 784 total square inches of cooking space. Each grate can be adjusted to accommodate whatever type of food your heart desires. The large capacity water bowl and wood chip box are made with heavy gauge, porcelain enameled steel for hours of maintenance free cooking. The temperature gauge features a "smoke zone" which indicates the ideal temperatures for infusing smoke flavor.
