I had the same problem. The 1/8" fitting going into the burner was flowing way to much volume of propane. I took JB weld and filled the 1/8" nipple full. Then I took a 0.030" drill and drilled a hole through the JB weld. This restricted the flow enough to get a blue flame that wouldn't turn orange. I have brewed on it several times without any issues. Another thing to look at is make sure that there is nothing in to tube of the burner. Spider webs will mess up the flow of propane or gas also. Gook luck this should fix your issue.
