How Dryer Vent Exhausting Relayed to Fire
One gallon or more of water must be disposed of for every typical load of laundry. Because of the moisture, exhausting the dryer to the outside is a must. Indoor exhausting can create conditions that support mold growth and degrade indoor air quality.
Proper exhausting is of particular importance with gas dryers. In addition to moisture and lint, a gas dryer’s exhaust duct carries the byproducts of combustion, including carbon monoxide.
A lot of lint is produced during the drying process, and lint can restrict or block dryer ducts. A poorly exhausting dryer is not only less efficient, it can also be a fire hazard due to the extreme flammability of lint. Clogging can also cause moisture to accumulate and seep out the duct, leading to moisture damage.
