[TheForge] Traveling Gas

[Steve Smith]

Jerry,

Try the existing burners first (Reil, Porter, etc.). The work *really* 
well, and I don't think they will work as well if you put screen in 
them. There is no problem in these burners with the flame climbing the 
tube, the flame is controlled by the flare at the business end.
