Dryer vent installation: materials, length, elbows and termination
Use 4 in rigid or semi-rigid metal duct with a smooth interior, keep the run within the code or manufacturer limit (the model code limit is 35 ft, reduced for each elbow, unless the dryer maker allows longer), and terminate outside with a backdraft damper and no screen. Never vent into an attic, crawl space or wall cavity.
Electric dryer cord change (3-wire to 4-wire or reverse)
Match the cord to the receptacle. With a 3-wire cord the neutral-to-cabinet ground strap (or green screw link) stays in place. With a 4-wire cord the strap is removed, the green wire goes to the cabinet ground screw and the white to the center neutral terminal only.
Gas dryer connection (BLOCKED: refer to a licensed gas installer)
Connecting, disconnecting or leak-testing a gas line is licensed gas work in most US jurisdictions. A handyman may prepare the space, the 120 V outlet and the vent, then the gas connection and leak test go to a licensed gas installer or plumber.
