The problem with most dryer vents is not only do they let warm moist dryer air OUT, they allow cold air and sometimes insects, mice and birds IN.
Replacing your existing dryer vent with a new energy-saving dryer vent closure will keep critters out, and help you save up to 10 percent on the energy your dryer uses. The vent/closure features a floating valve that keeps the vent closed when the dryer is not in use.
The energy-saving dryer vent closure consists of two parts. Begin by inserting the smooth edge of the plastic elbow into the bottom of the plastic vent body.
Prepare the vent opening by removing the old hood and flapper of the existing dryer vent by removing the screws. Once the vent is removed, clean out any lint that may have accumulated in the tube.
To install the new vent, place the flat portion of the elbow against the side of the house. The vent must be mounted in a vertical position. Line up the holes on the elbow and the side of the house. Mount with the screws provided through the top bracket of vent and flat portion of elbow.
The entire assembly may be painted with water-based paint if desired.
