If the exhaust duct appears to be kinked, or is crushed, it’s time to consider replacing it with DryerFlex® - a safer, crush-resistant choice. The smooth interior not only prevents lint from building up inside the exhaust duct, it promotes maximum airflow efficiency to keep the dryer performing as it should.
Step 1: Open the package and remove the DryerFlex.
Step 2: Some installers prefer to trim DryerFlex, which can easily be done by poking a hole and using a razor to cut around the circumference of the duct. DryerFlex can alternatively be installed at full length.
Step 3: Once determining the length to install, flatten and extend the edges on both ends of the DryerFlex.
Step 4: Wrap both ends of the DryerFlex with UL-Listed foil tape and flatten.
Step 5: Use a plastic squeegee to smooth the tape against the edge of the DryerFlex. Repeat this process for the other end.
Step 6: Slide the DryerFlex onto the end of the rigid duct that either protrudes from the wall, or the part that is coming into the Dryerbox (if one is installed).
Step 7: Use a DryerClamp to secure the DryerFlex to the rigid duct. Apply and tighten securely.
Step 8: Use a second DryerClamp on the other end of the DryerFlex.
Step 9: Connect the free end of the DryerFlex onto the back of the dryer and tighten the DryerClamp.
Step 10: The DryerFlex is now installed and the dryer can be pushed back 4 inches from the wall, or right against the wall if a Dryerbox is installed.
