Installing a hood over the stove ventilates the cooking area and provides illumination. Once a huge piece of equipment, most hood stoves are now small and nearly unnoticeable. Ventless versions recirculate air using a filter, eliminating the need for ductwork. This project is easy and inexpensive if the correct steps are followed.
You will need:
Step 1: Shut off power to your work area from the electrical panel. Verify that power is off with the circuit tester.
Step 2: Remove any installed range hood by first locating the electrical connection under the cover, close to the light fixture. Locate the wire nuts, remove them, and separate connections in order to disconnect wiring. Have a helper support the unit while you loosen the screws that secure it in place. Do not remove the screws but slide the hood off them. Set the hood aside and then remove these screws.
Step 3: Your new stove hood should cover your entire cooking surface and hang over at least 3 inches on all sides. The hood should be placed 24 to 30 inches over the range or stove surface. Connecting wires should protrude a foot from your kitchen wall.
Step 4: Place the new hood on a flat work surface, turn it over, and find the metal cover near the lighting unit. If the underside of this hood features a large panel, remove this to locate the cover. Remove the cover to expose the assembly and wiring for the fan.
Step 5: Ask a helper to hold the new hood in the proper location. With the pencil, mark locations underneath your kitchen cabinet that line up with the keyhole-shaped holes in your hood. Drive one screw into each location with the screwdriver, screwing about half way into your cabinet. Put the new hood on these screws. If the cabinet underside will not accommodate these screws, attach the wood blocks to both sides of your kitchen cabinet. Make sure that the bottom of each block and the bottom of the cabinet lip are flush.
Step 6: Thread electrical wiring from your kitchen wall, go through the cable clamp, and into the small hole on the back of your new hood. Both the fan and light have a black and a white wire. Use one wire nut to connect the black wire coming from the wall to the two black wires on your new hood. Use another wire nut to connect the two white wires coming from the hood with the white wire coming from the wall. If the wall also features a green wire or a bare wire, attach it to the small green grounding screw on the new hood. Tuck all of the wires into the compartment and replace the cover.
Step 7: Tighten each screw that supports the hood until it is secure.
Step 8: Go to your electrical panel and turn on power to this work area. Test the fan and hood light to verify that they were installed properly.
