The stone is not hot enough for the flame. Heat for longer until the stone itself is at least about 400 °C (750 °F): the display reads the oven, so check the stone with an infrared thermometer (Tom's Guide, Arc XL review). For New York style, turn the dial down and bake for longer (Tom's Guide). Allow about 5 minutes on high between pizzas for the stone to recover.
