Installing a freestanding range with double oven is a straightforward process. Like other types of kitchen ranges, you’ll simply need to position the range where you want it in the kitchen, then plug the power cord in. Gas double oven ranges will also need to be connected to the gas supply line.  Installing a wall double oven is more complex. Since these appliances require hard-wired installation, it’s a job that is typically best done by an electrician. However, if you are handy and frequently take on home projects, you may be able to successfully install a wall double oven. Follow the installation instructions provided by the manufacturer. Generally speaking, you will need to first turn off the electric power supply from the fuse box. If you have an existing wall oven, remove the doors to make the oven lighter. Then, remove the anchoring screws to dislodge the wall oven. It may be beneficial to remove the oven doors from the new wall oven, as well. Next, slide the new wall oven into the opening. Place the feet of the oven and secure the appliance according to the manufacturer’s instructions. Finally, connect the electrical wires to the junction box and re-install the oven doors (if you removed them).
