Lit my brand new lbge for the first time today. Filled w/bge charcoal and lit w/ bge starter. Let the chunks burn until the smoke cleared up and closed the bottom vent to the width of a dime and barely cracked the top vent. I've been reading this forum and so far have only gotten to page 45 but have learned that heat control takes some getting used to. With that in mind, I thought I was starting off with my vents set for relatively low heat. To my surprise within seconds of closing the lid, my dome temp shot above 500. I opened the lid to get rid of some heat and then I completely closed the top vent and all but closed the Bottom. Same result. I left the lid closed and waited several minutes but the temp never fell below 500 and actually was slowly rising. So, we cooked some burgers over the open flame for the first meal. So, what did I do wrong? I was hoping to work UP to temp by that was not the case.
