Abstract: A gas fired deep fat fryer, typically provided with legs equipped with optional wheels and including a tank for containing a cooking medium and fitted with a drain line and valve for draining the cooking medium from the tank. A single burner tube projects through the tank wall from a vented tube stub which receives an orifice nipple that introduces gas into the burner tube. The burner tube defines a U-shaped heating loop in the tank and terminates at the opposite end from the tube stub in an upward-standing stack that extends through the tank wall. Heat is applied to the burner tube from the orifice nipple and is dissipated through the U-shaped heater loop directly to the cooking medium. A grate is placed over the U-shaped heating loop in the tank to prevent food in the tank from directly engaging the burner and sinking to the bottom of the tank.
