Installing a built-in oven can update the appearance of your kitchen or give you more features and capabilities than your existing built-in oven. Different colours and styles allow you to choose an oven that will complement your kitchen's decor. You will need an assistant to help you lift the built-in oven and put it into place. You may also need an electrician if you are not able to handle the wiring portion of the installation.
Shut off the circuit breaker to the kitchen. If you are unsure which breaker controls the kitchen electricity, turn off the main breaker to the home.
Open the oven door to check for additional packing materials or instruction manuals.
Place a table in front of the cabinet opening where the oven will go. Make sure the table is the same height as the bottom of the opening and is sturdy enough to hold the oven's weight. Have another person help you lift the oven onto the table.
Connect the oven's wires to the electrical junction box (inside the cabinet) according to the manufacturer's instructions. Built-in wall ovens are wired directly into the junction box, not plugged into a wall outlet. Consult an electrician for this step if you are uncomfortable working with electrical wiring.
Push the oven across the table so that it slides into the cabinet opening. Instead of lifting up on the handle of the oven door, open the door and grab the inside of the oven to move it into place.
Locate the mounting holes inside the oven. Insert the wood screws into the holes to attach the built-in oven to the cabinet walls.
Attach any pieces of outside trim that came with the oven. Some built-in ovens do not have any trim; others come with several pieces that will conceal gaps between the oven and cabinet walls.
Turn on the kitchen's circuit breaker. Turn on the oven to test whether it is receiving power.
These instructions only apply to kitchens that already have an opening for a built-in oven. If your kitchen does not have one, you can hire a contractor to cut through the existing cabinets and wire an electrical junction box.
Before shopping for a built-in oven, measure your cabinet opening to ensure that you purchase an oven that will fit. Aslo, check the manufacturer's electrical requirements to be sure that your home's electrical system is sufficient for the oven you wish to install.
