- Power tester or multimeter
- Pipe wrench or pliers
- Reflective foil tape
- Junction box for 240V

Step 1: Pre-Installation Planning
- Check Power Needs
- Most cooktops need a special power line. It should be 240 volts with a 40-amp breaker.
- See if your home has this. If not, call an electrician.
- Measure the Hole
- The hole size is usually 28 to 29 inches wide and 19 to 20 inches deep.
- Always check your manual for the exact size.
- Leave Space Around
- Keep 30 inches above to cabinets.
- Leave 1 foot on each side.
- Have 8 inches on one side for tools.
Step 2: Turn Off Power
- Go to the breaker box. Turn off the power to the kitchen.
- Use a tester. Make sure no electricity is flowing. Do this before touching wires.
Step 3: Remove the Old Cooktop
- If you have an old one, disconnect the wires. Be careful.
- Take pictures of the wires first. This helps you remember.
- Lift out the old cooktop. Clean the area well.
Step 4: Prepare the Countertop Cutout
- To make a new hole, mark the size with tape.
- Use a jigsaw to cut. Make the edges smooth.
- Put foil tape inside the hole. This stops heat damage.
Step 5: Wiring the Cooktop
- Find the Junction Box
- Your cooktop wires connect here. They are black, red, white, and green.
- Connect the Wires
- Black to hot (L1)
- Red to hot (L2)
- White to neutral (if needed)
- Green to ground
- Secure the Wires
- Use wire nuts and tape.
- Make sure no copper is seen.
Step 6: Position and Secure the Cooktop
- Get a friend to help. Lower the cooktop into the hole.
- Put the wires through first. Then lower the back down.
- Use the clips or brackets that came with it. This holds it in place.
Step 7: Final Checks and Testing
- Turn the power back on at the breaker.
- Test each burner. See if they heat up.
- Listen for odd sounds. Look for flickering lights or codes.
- If all works well, you are done.
