Certified Dryer Exhaust Technician #100

Fires in dryer exhaust ducts pose a serious risk to consumers. In fact, the Consumer Product Safety Commission (CPSC) has issued a consumer product safety alert. According to CPSC, annually there are 15,500 fires, 10 deaths and 310 injuries due to dryer exhaust ductfires. These fires result in millions of dollars in property loss.

Because the dryer duct is usually a 4" diameter, the slightest amount of deposit can greatly reduce the ability to exhaust. When it starts taking longer to dry the clothes, the problem is not usually the dryer, but rather the exhaust system.

As more homes have clothes dryers and are built of tighter construction, the proper operation of the dryer becomes critical. Dryers are exhausting air from the house while they are in operation. Gas dryers are also venting the products of combustion in addition to the moisture from the clothes. Lint in the exhaust system can easily become fuel as temperatures rise and the duct becomes restrictive. Dryers may be located in an area where they must compete for combustion air with gas-fired water heaters and furnaces or boilers. This can lead to life-threatening malfunctions on the part of the heating equipment.*
