Section 8 - Range DisassemblySection 8 - Range DisassemblyDANGER Turn off electrical power at the main power supply and the gas supply at the gas supply valvebefore servicing the range. Failure to turn off electrical power and the gas supply to the rangewill result in a electric shock and explosion hazard.Door RemovalWARNING Do not attempt to disengage the hinge locks on the door while it is removed from the oven. Thehinge springs could release, causing personal injury. Do not lift or carry the oven door by the door handle. Open the oven door completely. Pull the hinge locks forward on both hinges,until they stop. Raise the door so that it is at a 15 anglefrom the front of the oven. Hold the door withone hand on each side. Lift the door up andout.Page 8-1
Dacor Range Service ManualDoor InstallationWARNING Be sure that the notch on the bottom of each hinge rests on top of the lower lip of each hingereceptacle before attempting to open the oven door. Failure to do so may cause the door to falloff its hinges, resulting in personal injury or damage to the door. Rotate the hinge locks toward the front of the range immediately after installation of the door.Failure to do so may cause the door to fall off its hinges, resulting in personal injury or damageto the door. Grasp the oven door on opposite sides andhold it at a 15 angle from the front of theoven. Slide the hinges A into the hingeopenings B , resting the bottom of the hingearms C on the lower lip D of the hingereceptacles. Continue to hold the door at a15 angle with one hand while pushing in oneach of the bottom corners of the door. Pushuntil the notch E on the bottom of eachhinge slips over the lower lip D of eachhinge receptacle. Lower the door to the fully opened position. Rotate both hinge locks toward the oven. Open and close the door completely to ensurethat it is properly installed.BAEDCPage 8-2
