I assumed he was talking about my system too. If I had a welder I would have built something out of steel but I have woodworking tools so that is what I went with. I really don't have a problem with the burner. The vast majority of the heat is directed upwards so there isn't much heat under the burner myself. I do make sure that I don't have the burner too close to the tier that supports the mash tun. At some point I will probably add a heat shield to it.
