Odds are that the view behind your dryer closely resembles one of the pictures to the left. Just like every other home across the United States with a laundry room that is not in the basement, the standard practice of running the exhaust pipe is to penetrate the drywall with a 90-degree elbow is very common.

Firefighters Remove Burned Dryer This obviously becomes a serious fire safety issue. Lint accumulation and reduced exhaust airflow feed on each other to provide conditions ripe for a fire. Lint is highly combustible and decreased airflow causes overheating of the exhaust environment, demanding excessive cycling of the high temperature limit switch and eventual failure.

If your clothes are taking longer to dry or if the velocity of air exhausting from the dryer vent hood is minimal, maintenance is needed. Clothes dryers are prone to lint build up if there are numerous 90's in the system or the distance is excessive.

Therefore, the exhaust hood (roof jacks especially), transition hose and metal ducts should be inspected and cleaned on a regular basis.

Proper Venting Reduces Dryer Fire Hazard It is strongly recommended that the wire bound vinyl ducting not be used. In most states it is specifically disallowed in the building codes. Vinyl ducts often collapse causing blockage and lint build up within the dryer. This type of plastic or vinyl ducting can ignite or melt and will not contain a fire within the dryer.
