kinda hard to see what I am trying to show but in the top of the stove there are 4 tubes with holes in them. Hot exhaust gases are directed through the top through convection effect, through the holes in the tubes and burn a second time adding efficiency to the burn. Most newer stoves have these now and it is a good feature. It also helps keep the glass clean which mine is not now but I never clean the glass anymore. If I burn a hot fire it all clears up like new so from time to time I burn it hot.
