SOTO ST-310, ST-340 heat shield table. When you place a frying pan, iron plate, mess tin, or other cookware on a single burner such as the SOTO ST-310, a large amount of radiant heat is generated from the burner itself and the heat source placed on it. This heat shield table prevents that radiant heat from being transmitted to the gas cylinder, preventing the gas cylinder from exploding due to high temperatures.
