I converted my stove from natural to LP. I went through all of the steps in the instructions for the stove top and oven/broiler. Everything works except the oven flames come clear up into the oven several inches. I have tried tightening the valve more and still no results. It did take quite a bit of adjusting to get the broiler dialed in, but I have pretty much tightened the oven valve as far as it can go. Any Ideas? I am tired of using a toaster oven!
