Abstract: A cooking apparatus has a food support with food engaging structure, such as a rotisserie spit. A firebed is mounted under the food support to heat food at the food support. A heat reflective vault is mounted over the food support for reflecting radiant heat back down toward the food support. The vault extends over the food support while still providing access from the side. A drive mechanism can vertically adjust the firebed to adjust heat flowing toward the food support. An elevator motor may be coupled to the drive mechanism for vertically positioning the firebed. A thermostat responsive to heat from the firebed and coupled to the elevator motor can control elevation of the firebed.
