Calibrating your BetterVent

You can find a link to our installation video at the "About Us" page or follow the instructions with photos below to calibrate your BetterVent. It's easy!

There are electric dryers of all sizes, all with different exhaust outputs. Since they all operate differently, it is necessary for the purchaser to set the Safety Vent Flap to operate with their specific dryer.

Just follow these easy instructions.

  • First, make sure that you have cleaned the lint screen inside your dryer. This should be done after each dryer load as recommended by the manufacturer.
  • Next, take the smallest magnet from your accessory pack, peel off the brown paper and attach it to the inside of the Safety Vent Flap, as shown.

                                                                

  • Now, find a book, notebook, clipboard or magazine. Turn your dryer on and cover about 25% of the door.

                                                                   

  • What should happen now is your Safety Vent Flap will open or stay closed. If it stays closed, continue to move upwards until the flap opens.

                                                                    

  • If it opens before you reach 80% coverage of the door, add one of the 4 remaining magnets to the top of the closed Safety Vent Flap and do the test again. Continue to add magnets to the top until Safety Vent Flap opens at 80% coverage. Note: most users do not have to add more than 2 magnets.

                                                                      

  • Ideally, you want the flap to open at about 80% coverage with the dryer running. The Safety Vent Flap is designed to alert you that it is time to clean or replace the blue and white filter inside. Always remember, the white side of the filter faces out when the door is closed
