I have an odd problem. The front tube on my Drolet twists some after a few days of running. It's not really a big deal but the holes slowly start moving up so the secondary flame is blasting away at the baffle board. It is starting to erode it on the front edge. Thought about maybe using a hose clamp or something to keep it in position. They don't use pins or screws to position it. The tube is notched so it's kind of like a twist-lock. Thanks!
