Residential dryer vent lenghts may not have an equivalent length greater than 25 feet. Five additional feet for each 90 -degree bend must be added to the actual physical lenghth. This will determine the vent's actual resistance to the airflow.
- Homes with larger families or where dryers are used heavily are at greater risk.
- Flexible plastic duct is no longer code- approved for clothes dryers. It is normally one of the first things burning lint will ignite, having been shown to flame in as little as 12 seconds. Lower cost and high flexibility often make it attractive to unadvised homeowners installing their own machines.
- Flexible duct made of thin foil is not recommended for clothes dryers. It's tendency to "kink"and stop airflow makes it dangerous to use.
