Check the manufacturer's electrical requirements for the new stove outlet. If you have an older home, you may need to install a three-prong outlet. Contact an electrician to re-wire the outlet if this is the case.
Remove the stove from its packaging, except for the cardboard bottom. Use a utility knife to cut away the cardboard and plastic wrapping. For the time being, leave the stove standing on the cardboard bottom as it will help you slide the stove across the kitchen floor.
Install the anti-tip brackets supplied with the new stove in a location that will allow the stove to slide into a locked position and prevent it from tipping over. These brackets are crucial for the safe operation of your stove so follow the supplied manufacturer's instructions carefully. Fasten the anti-tip brackets by drilling a pilot hole into the surface where the stove will be anchored, typically the floor. Tap the supplied anchors into each hole with a mallet then screw the anti-tip brackets into the anchors.
Connect the power cord to the stove, according to the manufacturer's instructions. Remove the back panel from the stove if necessary. Slide the stove so that it lines up directly with the opening in the counter top but do not slide it into the counter cavity just yet.
Hook up the gas with whatever flexible gas connection is provided with the stove if it uses gas; otherwise, skip this step. Follow the manufacturer's instructions to make the connection and use a plumber's wrench to secure the line in place.
Remove the stove drawer from the bottom of the range. Ask a friend to help you pick the stove up off the cardboard bottom.
Level the top of the stove by adjusting the legs beneath it. Use a level to check that the stove top is balanced.
Plug the stove into the wall.
Slide the stove into the counter top cavity. Look underneath the stove to check that the stove is aligned with the anti-tip brackets in the floor.
