Length and Type
Maximum Dryer Vent Lengths
The maximum length a dryer vent can be before problems arise, or are noticed, varies greatly between brands and models. The vent material and the type of outside vent cover being used also contribute to the maximum vent length allowed.
New Materials of Dryer Vents
In all cases, the longest possible working vent should be made of rigid metal vent material with a large mouth or louvered outdoor hood. Flexible metal ducting, although a bit easier to work with, causes reduced air flow due to its corrugated design and will contribute to a lint buildup in the ducting over time.
No Nylon Ducting for Dryers
Flexible Nylon ducting is no longer approved in most areas for dryer venting due to the possibility of a fire hazard and has never been approved for use on gas dryers.
Vent Outdoors
In the United States, all gas dryers must be vented to the outdoors by law!
Proper Dryer Vent Installation includes:
The path of the dryer duct:
Any lint that escapes the dryer's lint filter should be blown right outdoors. (Any accumulation which occurs in a dryer's ducting is usually a sign of poor air flow, especially at the location(s) it occurs.) In such cases, the vent line should be evaluated to locate and correct any deficiencies it may have.
Short Dryer Vents
The vent should be as short and as straight and with as few elbows as possible. The more bends and turns, the greater the reduction in air flow there is, and the more areas where lint can accumulate. More bends will also hamper dryer vent cleaning, which should be performed yearly, if not seasonally.
Dryer Vent Problems
It is sometimes possible to tell if a dryer's vent is the cause of poor drying by totally removing the vent line from the dryer and doing a couple of loads. If drying improves, you can be sure the vent is (at least part of) the problem.
No Metal Screws, No Obstructions in Dryer Vent Installation
When attaching multiple sections of vent pipe together, Dryer Vent Wizard does not use sheet metal screws. We use metal foil tape instead. Any protuberances into the vent will cause obstructions where lint can accumulate --eventually leading to a restriction, which will hamper dryer vent cleaning and allow lint to build up. Those protuberances will also make the inevitable dryer vent cleaning much more difficult.
