I just got a smoker with a venturi type burner. The problem is that somehow a flame will burn inside the venturi opening. The smoker manual says that means there is an obstruction in the venturi. However, this is a brand new smoker and there is certainly nothing blocking the venturi openings. I feel like this might have something to do with excessive wind somehow causing a draft that leads to propane coming out of the venturi and being ignited by the burner flame. I am having trouble finding anything online about this problem. Any suggestions?
