    Over range microwave venting
    Aaron Stickley

    The first step to installing an over-the-range microwave is to decide on the venting option. The way in which you vent will depend on the unit and the configuration of your kitchen. If you are replacing an existing microwave or a range hood, the best option will likely be to use the existing venting route for the new microwave. It may be necessary to install a new exhaust adapter, but you can use the existing roof or wall vent route.

    If there is no existing venting route, decide which option is...MORE best for your kitchen and use the template provided to open a vent in the wall or cabinet. If you are mounting the microwave on an exterior wall, then you can use a wall vent; otherwise, a roof vent will be needed. Proper range venting is very important so follow the manufacturer’s specifications for installing a new vent.

    Note: Make any necessary adjustments to the microwave’s blower to ensure that it will blow exhaust in the direction of the vent.

    Position the mounting bracket at the appropriate height by using the wall template. Use the stud markings to guide you as you screw in the mounting screws.

    Mounting the microwave requires two people. Place the electric cord on top of the microwave so it's handy when you need to feed it up through the cabinet. While each person holds onto one side of the microwave, position the bottom back edge onto the edge of the mounting plate. There are tabs on the mounting plate that need to feed into the corresponding slots on the bottom of the microwave. When the tabs are in place, feed the electric cord through the opening in the cabinet. Then push the...MORE top of the microwave back and into position.

    While holding the microwave in place, reach up and insert the mounting bolts through the cabinet into the top of the microwave. Tighten the bolts to secure the microwave onto the cabinet bottom. Finish the installation by connecting the power cord and the exhaust adapter, if necessary, for top venting.
