I've only got a couple smokes under my belt, both times were pork butt, so low temps. I was getting ready to throw some chickens in there so I filled my water tray, smoke tray with alder, turned my Smoke Vault to Med and left it for about 10 mins. Came back and the temp was up over 300, so I turned it down but the temp kept shooting up, so I opened the door to see all of my wood chips ablaze. I know that I could soak the chips, but I've read that a lot of people don't prefer it so I just figured it wasn't necessary. Has anyone else had this problem?
