Dryer hoses are used to vent not only the hot air out of the dryer, but also any lint that may get though the lint trap. It's important to have an airtight connection when you connect the hose, as any leaks will allow both lint and heated air that could produce condensation eventually could lead to mold. Using a heat-retardant hose and spring-tensioned clamps will ensure your dryer operates cleanly and effectively.
Rotate the dryer at an angle so you can access the location of the dryer vent in the wall and the dryer vent connection on the back of the dryer.
Unplug the dryer from its 220-volt outlet plug to avoid accidental startup during the installation process.
Squeeze one of the hose clamps with the pliers to open it up and slide it over one end of the dryer hose. The clamp will have two tabs that, as you squeeze together or toward each other, will open the clamp. As you let go, the tension of the clamp will close. Slide it down the hose about 6 inches from the end. Slide the end of the hose over the dryer vent connection on the back of the dryer.
Squeeze the clamp open with the pliers and slide it to about 2 inches from the end of the hose. Slowly release the pliers, and the tension of the spring will clamp down on the hose, securing it to the dryer's vent connection.
Repeat Steps 3 and 4 to attach the remaining end to the wall vent the other hose clamp.
Plug the dryer back into the 220-volt outlet and slide the dryer back into its original operating location.
Turn the dryer on and test for power.
