Preparation for Vented Microwave Installation

Before starting, make sure you gather all the necessary tools and materials for a smooth installation. Adequate preparation is essential for success.

Tools and Materials:

  • 4-inch hole saw
  • Angle grinder
  • Anti-tip bracket
  • Ductwork
  • Duct louvers
  • Electric drill
  • Flexible elbow
  • Level
  • Mounting hardware
  • Pilot bit
  • Reciprocating saw
  • Stud finder
  • Vented microwave

Safety Considerations:

Ensure safety by turning off the power and gas supply before working with electrical or gas appliances. If you’re unsure about electrical or gas connections, consider hiring a licensed professional.

Step 1: Remove the Old Appliances

Before installing your new vented microwave, you need to remove the existing appliances.

Disconnecting the Gas Stove:

  1. Turn off the gas supply.
  2. Disconnect the gas line from the stove.
  3. Unplug any electrical connections.
  4. Carefully slide the stove out.

Removing the Old Microwave:

  1. Unscrew any mounting screws holding the microwave in place.
  2. Disconnect the power cord.
  3. Carefully lift and remove the microwave from its mounting bracket.

Step 2: Install the Mounting Bracket

  1. Use a stud finder to locate the studs in the wall where the microwave will be mounted.
  2. Mark the spots for the mounting bracket holes.
  3. Drill pilot holes and secure the mounting bracket into place.

Step 3: Prepare the Cabinet for Microwave Installation

To ensure a proper fit for your new microwave, you may need to modify the cabinet space.

  1. Measure and mark the position for the vent hole in the cabinet above the microwave.
  2. Use a hole saw to cut the vent opening.
  3. If necessary, install support structures inside the cabinet to secure the microwave.

Step 4: Place the Microwave

  1. Lift the microwave into position, aligning it with the mounting bracket.
  2. Secure the microwave to the bracket and the cabinet.
  3. Plug in the microwave’s power cord to the designated outlet.

Step 5: Install the Venting System

A functional venting system is essential for your microwave. Follow these steps for vent installation:

Determine the Vent Path:

Before cutting any holes, plan the vent path. Make sure to avoid structural obstacles in the wall. Trethewey demonstrates how to offset the exhaust for better installation in the video.

Cutting the Vent Hole:

  1. Mark the position for the vent hole on the exterior wall.
  2. Drill a pilot hole from the inside.
  3. Use a hole saw to cut the full-sized hole from both inside and outside.

Ductwork Installation:

  1. Measure and cut the ductwork to fit the microwave’s vent outlet.
  2. Attach the ductwork securely to the microwave’s vent.
  3. Seal any joints in the ductwork to ensure there are no leaks.

Installing the Duct Louvers:

  1. Align the louvers with the vent hole.
  2. Secure them using appropriate mounting hardware.
  3. Ensure that the louvers are tightly sealed to prevent leaks.

Step 6: Connect the Gas Stove (if applicable)

If you are installing a new gas stove in conjunction with your microwave, these steps will guide you:

Modify the Gas Line:

In some cases, the gas line might need adjustments, including removing old fittings and installing new ones for proper clearance.

Connect the Gas Line:

  1. Apply pipe thread compound to all threaded connections.
  2. Attach the flexible gas line to the stove and supply line.
  3. Tighten all connections securely.

Safety Check:

After making the gas connections, perform a leak check by applying a soap and water solution to the connections. Turn on the gas supply, and look for bubbles indicating a leak. If any leaks are detected, tighten the connections or remake them.

Step 7: Final Steps and Testing

After all installations, follow these final steps:

Securing the Appliances:

  1. Install the anti-tip bracket for the stove following the manufacturer’s instructions.
  2. Double-check that the microwave is level and securely mounted.

Testing the Microwave:

  1. Plug in the microwave and power it on.
  2. Test all microwave functions, including the vent fan, to ensure it works properly.
  3. Check that the vent exhausts air to the outside.

Testing the Stove:

  1. Turn on the gas supply.
  2. Light each burner to confirm that they function properly.
  3. Test the oven and any additional features of the stove.

Step 8: Ensuring Ventilation Efficiency

To maintain proper air quality and extend the lifespan of your microwave, ensure that the vent system works efficiently. Check airflow and ensure there are no obstructions that could reduce the effectiveness of the ventilation.

Conclusion

Installing a vented microwave is a practical upgrade for your kitchen, improving both functionality and air quality.
