A hood installed over a stove provides lighting and ventilation to the kitchen. Over the years, this unit has been redesigned to the point where it is now small and unobtrusive. A vent-free model uses a filter to recirculate air through the room and does not require ductwork. Installing a vent-free hood with your new stove or range is not difficult or expensive to do if you follow the instructions below.
You will need:
Step 1: Turn off the power to the area at the electrical panel. Use the circuit tester to ensure that the power is off.
Step 2: Remove an existing range hood. Look under the cover and find the electrical connection near the light fixture. Remove the wire nuts, then separate the connections to disconnect the wiring. Have someone help support the weight of the unit. Loosen the screws securing it is place but do not remove them. Slide the hood off these screws, set it aside, and remove the screws.
Step 3: The new hood should cover the entire cooking area and hang over 3 inches on each side. It should be located between 24 and 30 inches above the range surface. All connecting wiring should protrude one foot from the wall.
Step 4: Turn the new hood over on a flat surface and locate the metal covering located near the lighting fixture. If a large panel covers the underside of the hood, remove this to find the metal covering. Then, expose the fan assembly and wiring by removing the metal covering.
Step 5: Have someone help hold the hood in the correct position. Use the pencil to mark the spots on the underside of the kitchen cabinet that align with the keyhole-shaped holes on the hood. With the screwdriver, drive a screw into each spot, going approximately halfway into the cabinet. Place the hood on the screws. If the underside of your kitchen cabinet does not accommodate screws, attach wood blocks to both sides of the area, making sure the bottom of the blocks are flush with the bottom of your cabinet lip.
Step 6: Thread the electrical wiring from the kitchen wall and through the cable clamp into the small hold located on the back of the new hood. The light and fan will each have a black and white wire. Connect black wire from the wall with the two black wires on the hood, using a wire nut. With another wire nut, connect the white wire from the wall with the two white wires on the hood. If a bare or green wire is protruding from the wall, attach this to the green grounding screw located on the hood. Tuck all wiring into place and replace the metal cover.
Step 7: Tighten the screws supporting the hood until they are secure.
Step 8: Turn on the power at the electrical panel. Test the hood light and fan for proper installation.
