Sitting directly on top of the BioLite CampStove burn chamber, the Fuel Intake Lid from the BioLite Portable Grill allows you to directly feed the fire while continuing to cook your food. Close the lid and the flames are spread up through the grill body. The vortex flame of the CampStove creates three temperature zones (HI, MED, LO) satisfying any typical grilling need. You can see more about the component parts on the Portable Grill Product Page.
