Add great wood smoke flavor to all your grilled food using the independent smoker box and burner. The smoker burner is placed between two main burners for an even distribution of the smoke. Use the convenient stainless steel tray to add wood chips of different flavors as you grill. Hickory, mesquite, apple, cherry, pecan and alder are just some of the choices. The smoker box and burner also allows for cold smoking for added flavor.
