THE INSTALLATION INSTRUCTIONS CONTAINED HEREIN ARE FOR THE USE OF QUALIFIED INSTALLATION AND SERVICE PERSONNEL ONLY.
  • Page 4 INSTALLATION Ventilating Hood The ideal method of ventilating a convection oven is the use of a properly designed ventilat- ing hood. The hood should extend at least 6” beyond all sides of the oven. The hood should be connected to an adequate mechanical exhaust system. Information on the construction and installation of ventilating hoods may be obtained from the “Standard for the Installation of Equipment for the Removal of Smoke and Grease Laden Vapors from Commercial Cooking Equipment”, NFPA No.

Either a flue deflector or a draft hood is shipped with every unit. The flue deflector is intended for use when the oven is installed under a properly designed hood. When the oven is directly connected to the vent system, the draft hood must be used.
  • Page 8 INSTALLATION Gas Connection Before connecting oven to the gas supply line, be sure that all new piping has been cleaned and purged to prevent any foreign matter from being carried into the controls by the gas. In some cases, filters or drops are recommended. A separate gas shutoff valve must be installed upstream from the gas pressure regulator adjacent to the oven and be located in an accessi- ble area.
  • Page 9 INSTALLATION Electrical Connection Unless otherwise specified, the oven is equipped with a 6 foot flexible supply cord for 115 VAC, 60 hertz. A terminal block is provided for 208/240 VAC, 60 hertz, single or three phase units. The wiring diagram is located on the back of the oven. THIS APPLIANCE, WHEN INSTALLED, MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES, OR IN THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL ELECTRICAL CODE, ANSI/NFPA No.
