How to Install a Periscope Dryer Vent
(Zedcor Wholly Owned/ Images)

Improper ventilation on a dryer vent can lead to increased electricity bills and even fire. The most common dryer vents are either plastic or corrugated, and sometimes both. Corrugated vents act like little speed bumps to the air flow from your dryer. The corrugations collect lint and dirt, and can clog the air flow, which increases drying time and energy usage, and presents a fire hazard.

  1. 1

    Unplug the dryer and shut off the gas valve if it runs on gas.

  2. 2

    Undo the clamp that holds the old dryer vent onto the dryer. Undo the clamp that connects the dryer vent to the external exhaust vent. Vacuum up any loose lint or dirt as you go.

  3. 3

    Attach the new periscope vent to the back of the dryer on the air duct. Tighten the clamp onto the new vent.

  4. 4

    Extend the new vent toward the external exhaust vent. Attach the flexible vent from the vent-connection kit to the external exhaust vent. Connect the second flexible vent from the second kit to the periscope vent. Secure both using the clamps in the kit, and tighten them with the screwdriver.

  5. 5

    Push or snap the two vents together to form one vent from the back of the dryer to the external exhaust vent.

  6. 6

    Plug the dryer back in and turn it on. Check all of the joints and the vents for air leaks. Secure any leaks with duct tape.
