Step 1 : Remove the old duct
Removing the old dryer duct system can be a dusty project. Remove the duct from the fitting that leads outside of the house first. Then remove it from the base of the dryer. Fold the venting into a roll and place it in a large garbage bag.
Use a vacuum to clean out any lint in the through-wall fitting and from the dryer vent. Also remove any lint from the back of the dryer.
Step 2 : Install the dryer Quick Connector
Slip the Quick Connector assembly over the dryer vent and tighten the worm drive clamp with a screwdriver.
Step 3 : Locate the position of the aluminum duct
Slip the aluminum duct over the Quick Connector on the dryer. Then slide the dryer into position against the wall. Mark the top of the vent on the wall. Then mark the center of the vent through the height mark you just placed on the wall to form an X.
Step 4 : Install the vent
Move the dryer away from the wall and remove the duct from the Quick Connect. Align the top of the vent with the marks you just drew on the wall. Have a helper hold the duct in place while you bend one of the wall straps over the duct. Drill a mounting hole through the hole in the strap on each side of the duct. Place a plastic wall anchor in the hole and then fasten the wall strap to the wall with the screws provided. Install the second strap in the same way.
Step 5 : Attach the vent to the through-wall fitting
Attach the flexible aluminum vent to the top of the duct you just installed with a worm drive clamp. Lead the other end of the duct to the through-wall fitting and secure that end with a clamp. Support the flexible ducting every 2 feet with a wall strap.
