Position the dryer close to the dryer exhaust vent, while still allowing room for you to work between the dryer and the wall.
Loosen the screw on the belt clamp with a Phillips-head screwdriver until the clamp slides over the end of the dryer duct. Do not loosen the screw too much and allow the belt clamp to separate.
Slide the belt clamp over one end of the dryer duct. Slide the end of the dryer duct over the dryer exhaust port sleeve on the back of the dryer.
Move the clamp toward the end of the dryer duct until the clamp is over the dryer duct and the exhaust port sleeve. Rotate the dryer clamp as necessary until the securing screw is facing the ceiling.
Tighten the screw with the Phillips-head screwdriver until the clamp is tight.
Repeat for the opposite end of the dryer duct, securing the duct to the outside dryer vent sleeve. Push the dryer into its working position once you clamp both ends of the dryer duct.
