Page 8: Installation
INSTALLATION OVEN LOCATION AND POSITIONING Choose a site away from major heat sources. DO NOT position so that hot air is drawn in from fryers, grills, griddles, etc. A heat barrier to the height of the oven must be installed if sited next to a burner, stove or range. Place the oven on a permanent nonslip/ nonflammable flat surface that is LEVEL, STABLE and STRONG enough for the oven and contents. -
Page 9: Electrical Installation
ELECTRICAL INSTALLATION DANGER! THIS APPLIANCE MUST BE EARTHED. FAILURE TO DO SO MAY RESULT IN ELECTRIC SHOCk AND DEATH. For all cord connected appliances: GROUNDING INSTRUCTIONS This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. -
