Tools and Materials You’ll Need

Before you begin the installation, gather the following tools and supplies to make the process seamless:

  • Vents GK 150 MA Garage Fan Kit (includes fan, external grille, ducting, and 6 ft corded plug)
  • Electric drill and hole saw (150 mm or 6" size recommended)
  • Screwdrivers (Phillips and flathead)
  • Measuring tape and pencil
  • Level
  • Stud finder
  • Safety glasses and gloves
  • Silicone sealant or caulking gun
  • Electrical wire connectors (if hardwiring)

Having everything on hand before starting will save you time and help ensure a professional installation.


Step-by-Step Installation Guide

Step 1: Choose the Installation Location

Select a wall or ceiling location where the fan can efficiently pull contaminated air out of the garage. Ideally, it should be placed opposite your garage door or windows to create cross-ventilation. Avoid locations near electrical panels or plumbing.

Pro Tip: If you often run vehicles inside your garage for extended periods, install the fan lower on the wall, since heavier than air exhaust fumes tend to settle closer to the floor.

Step 2: Mark and Cut the Vent Hole

  1. Use a stud finder to ensure you’re not cutting into studs or hidden wiring.
  2. Trace the outline of the duct diameter (6 inches).
  3. With safety glasses on, cut the hole using a hole saw or jigsaw.
  4. Smooth rough edges and test-fit the duct.

Cutting carefully ensures a snug, airtight fit for the fan and prevents unnecessary structural damage.

Step 3: Mount the Telescoping duct and the Fan

    1. Position the Telescoping duct into the cut hole from inside the garage. Slope the duct an 1/8" from the inner wall to the outside wall - to ensure any condensate flows outwards. Very rare but a possibility dependent on humidity levels.
    2. Align the internal fan mounting plate with a level to ensure proper fit.
    3. Secure the fan with screws provided in the kit.
    4. Connect the duct between the fan and the exterior vent grille/hood.
      Note: The kit includes a telescoping ABS duct that will need to be measured, trimmed, and test-fit to ensure a proper fit before you permanently secure the exterior grille. (Step 4)

Make sure all duct connections are tight and sealed-air leaks can reduce efficiency and cause backdrafting.

Step 4: Install the Exterior Vent Grille

On the outside wall, install the supplied Grille. (note: if you experience periods of inclement weather with lots of rain or snow you may want to look at the optional MV 152 VK Outer External Hood - designed with a sloping hood and an additional backdraft damper.) Seal the edges and the cavity with silicone caulking and you can also use spray foam insulation to ensure water doesn’t seep into the wall cavity.

Step 5: Hardwiring the Fan (Optional)

The GK 150 MA can be hardwired to your home’s electrical system, connected to a dedicated wall switch or plugged directly into a standard wall outlet. We always recommend hiring a qualified electrician for hardwiring.

  • For DIY installers: Follow local building codes and turn off power before wiring. Use proper connectors and ensure the fan is grounded.
  • For added safety: Consider hiring a licensed electrician for the wiring portion, especially if you’re not experienced with electrical work.
  • Using the supplied cord and plug: If you've decided to the use the supplied plug and cord, plugging in the unit will start up the fan immediately.

Step 6: Add the Interior Grille

Once wiring and ducting are complete, attach the slatted cover. This covers the fan housing for a clean finish and ensures airflow moves efficiently.

Step 7: Test the Fan

Turn on the fan and check for:

  1. A smooth, quiet operation
  2. Strong airflow exiting outside
  3. No vibrations or rattling
  4. Proper switch control
  5. Note: If you use the supplied plug the fan will run continuously until it is unplugged

If everything works correctly, your fan is now ready to provide continuous ventilation. Note: The GK 150 MA fan comes with automatic shutters that open when the fan is turned on and close when it’s switched off. It may take up to 30 seconds for the shutters to fully open during start or close during shutdown.

Safety Tips During Installation

  • Always wear safety glasses and gloves when cutting and handling ductwork.
  • Shut off electrical power before wiring.
  • Hire a qualified contractor and or an electrician
  • Follow all local codes and regulations for ventilation and wiring.
  • Ensure ducts are free of obstructions to maximize airflow.

Maintenance Tips for Long-Term Performance

Like any ventilation system, your GK 150 MA will benefit from regular upkeep:

  1. Clean the grille every 3–6 months to remove dust buildup.
  2. Inspect ducts annually for blockages or leaks.
  3. Check motor operation for unusual noises, which may indicate wear.
