Pre-Installation: Planning and Safety First
Before you pick up a single tool, proper planning is the key to a smooth installation.
1. Choose the Right Hood: Ensure your new range hood is the correct size—it should be at least as wide as your cooking surface. Decide between a ducted model, which vents air outside (highly recommended for performance), or a ductless (recirculating) model, which filters and recirculates air.
2. Check Your Ventilation Path: For ducted models, identify the most direct route to the outside. This could be through the wall behind the hood or up through the cabinets and ceiling.
3. Gather Your Tools and Materials: You will likely need a drill, screwdrivers, a jigsaw or reciprocating saw, a stud finder, measuring tape, a level, a pencil, and safety gear (glasses and gloves). You may also need ductwork, foil tape, and a roof or wall cap.
4. Turn Off the Power! Locate the correct circuit breaker in your home's electrical panel and turn off the power to the kitchen range and the area where you will be working. Use a voltage tester to confirm the power is off.
Step-by-Step Installation Guide
Step 1: Prepare the Installation Area
Use a stud finder to locate the wall studs. Mark the center point and the outline for the hood. If you are replacing an old hood, carefully remove it after disconnecting the ductwork and electrical wiring.
Step 2: Create the Ductwork Path
This is often the most challenging part. Based on your plan, cut the hole for the duct in the wall or ceiling using a jigsaw. If you are installing a wall-mounted hood, you may need to cut an opening in the cabinet above the range to accommodate the duct. Install the exterior vent cap before proceeding.
Step 3: Install the Ductwork and Electrical Components
Assemble the necessary metal duct pipes, connecting them from the hood's location to the exterior vent. Secure all joints with aluminum foil tape—do not use duct tape, as it is not heat-resistant and will fail. Important: If you are not comfortable running a new electrical line, consult an electrician. For a plug-in model, ensure an outlet is available within the cord's reach. For a hardwired connection, you will need to connect the hood's wires to the household wiring, matching the colors (black to black, white to white, and green or bare copper to ground).
Step 4: Mount the Hood Range
With the help of an assistant, lift the hood into place, carefully feeding the ductwork and electrical wires into the unit. Secure the hood to the wall studs using the provided mounting screws. Use a level to ensure it is perfectly straight. For under-cabinet models, you will be securing them to the cabinet above.
Step 5: Make the Final Connections
Connect the duct from the hood to the ductwork you've installed, sealing the joint tightly with foil tape. For a hardwired hood, complete the electrical connection by securely fastening the wire nuts and carefully tucking the wires into the housing. For ductless models, install the charcoal filters according to the manufacturer's instructions.
Step 6: Final Checks and Test Run
Double-check that all screws are tight, ducts are sealed, and the hood is secure. Once confirmed, you can restore power at the circuit breaker. Turn on the hood to test all fan speeds and lighting functions. Listen for any unusual vibrations, and check the exterior vent to ensure the damper opens when the fan is running.
When to Call a Professional
- While this is a manageable project, do not hesitate to call a professional if you encounter:
- If you encounter complex electrical work that requires a new circuit, do not hesitate to call a professional.
- Difficulty cutting through exterior walls or roofing.
- Uncertainty about local building codes.
