How to Install and Vent a Gas Dryer - Gas Dryer Installation and Venting


Natural gas dryers cost about one-half the cost of an electric dryer to operate according to the U.S. Department of Energy. Proper installation and venting are key to gas dryer operation.

Gas dryers must be installed by a qualified technician. It's not just a matter of plugging it in like an electric dryer. Consult with your local natural gas provider for a capable dealer who can insure proper installation. The technician will be sure that the dryer is level which will prevent the rotating drum from causing damage.

Natural gas dryers produce byproducts from combustion, primarily water vapor and carbon dioxide. It is important that these byproducts be exhausted or vented to the outside - never into the home. The technician installing the gas dryer should use rigid, metal duct piping and use the straightest, shortest duct possible. The end of the duct should be located outside so that the wet air coming out will cause no harm to the area around it. Too much wet air onto wood surfaces can cause mold and deterioration of a structure. An exhaust hood or vent that opens and closes with the movement of the air should be installed and cleaned regularly. An open end will allow cold drafts into the home and heated air to escape.

As the dryer is installed, be sure that you can easily access the lint trap for cleaning. The trap should be cleaned after every load - even a light layer of lint can impede drying time.
