Clothes dryers can be either powered by electricity or by gas. Some consumer reports state that the gas dryer is more efficient than the electric. Whichever type you may use, both will need to have a secure connection to the vent in your wall to safely release the excess heat and vapor. For gas dryers, a second necessary connection to the gas supply needs to be securely installed to avoid gas leaks.
1. Check for connection and electrical compatibility.
The shape and size of the vent hole at the back of your dryer should be compatible to the vent hole on the wall where you plan to install the dryer. Check the wall vent hole first before purchasing the dryer, to make sure you buy the right one. Most gas dryers need 117 volts, so you may also need to call in an electrician to modify the electrical wall outlet where you intend to plug in the dryer.
2. Turn off the electricity and the gas supply.
Before you start making the connections, you should first close the breaker feeding electricity to the wall outlet where you intend to plug in the dryer. If you're installing a gas dryer, you should also shut off the gas feeding the supply line to the dryer.
3. Connect the dryer's vent hole to the wall vent hole.
The hose used to make this connection should be fastened with a hose clamp, which is a metal ring that can be tightened with a screw. Both ends of the hose should be able to stretch without tearing to fit tightly on both the dryer's vent hole and the wall's.
4. Connect the gas dryer's supply line.
For gas dryers it's essential that the supply line connection at both the gas source and the dryer has no leaks, to prevent accidental fires or explosions. Use Teflon tape on the threads, and screw in a stainless steel connector using an adjustable wrench. You will need to consult your gas dryer's instruction manual for the exact way to do this, as different models have different connectors.
5. Turn on the gas and then turn on the electricity.
You can now open up the gas source to check if the supply line is securely connected and has no leaks. If you're sure about this connection, you can then turn on the breaker and plug in the dryer to the wall outlet.
6. Move the dryer into position.
With everything securely connected and plugged, you can now push the dryer back towards the wall. Leave enough space between it and the wall so that the hoses are not too crimped. Crimping could eventually cause tears in the hose or loosen the connections.
After proper installation comes proper maintenance. Gas and electric dryers vent out excess heat and moisture, and sometimes lint goes along with it and builds up in the vent hose. Clean this hose at least once a year to make sure it doesn't clog.
