Dryer Vent Cleaning – Prevent Dryer Vent Fires, Prevent Dryer Vent Problems

How Underwriting Laboratories (UL) has helped reduce dryer vent problems and dryer vent fire risks:

UL has worked with the Association of Home Appliance Manufacturers (AHAM) and the CPSC to reduce the number of clothes dryer vent fires.

Changes have been made to UL´s Standard for electric clothes dryers including:

• installation instructions, specifying using only metal exhaust duct materials;
• user instructions that lint be cleaned regularly from areas around the dryer and lint screen;
• routing wiring and keeping other electrical components away from heat-producing devices; and
• abnormal operations tests that simulate a blocked lint screen and exhaust at 25, 75 and 100 percent blockage.

Dryer Vent Wizard – Dry Clothes – Safe Homes, adheres to all of the UL recommendations.
