Route the dryer vent horizontally to the home's outside wall. Duct work should pitch 1/4-inch per foot to the outside. This keeps moisture out of the pipe. For basement laundry areas where your ductwork will run vertically to the outside wall, you may need to use 90-degree elbows.
Dryer vents should be sealed with foil tape as they can withstand the high temperatures encountered during machine use. Other tapes, even duct tape, are susceptible to failure under the extreme heat. Non-foil tape can also catch on fire.
For a dryer vent, you should use metal foil tape or aluminum tape. These types of tape are designed to withstand high temperatures and are more durable than regular duct tape. Avoid using plastic or cloth tape, as they can degrade or fail over time due to the heat and moisture from the dryer.
M1502.
According to the M1502. 5 code, the construction of a dryer duct has to be a minimum of 0.4 mm thick with a smooth interior. This means ribbed vents are no longer being used. Additionally, all duct joints must point in the direction of airflow.
Rigid metal options are the best types of dryer vent hoses. They are sturdy and completely smooth, meaning they catch the least amount of lint. If you're looking for the safest, smartest option, rigid metal dryer vent hoses should be your go-to.
Better Airflow: One of the primary benefits of using a hard pipe for dryer venting is that it provides better airflow. The smooth interior of a hard pipe allows air to flow freely, while the ridges and creases in flexible accordion piping can cause restrictions in airflow.
Some dryer vent installations also have an external lint trap, which is also known as a secondary dryer lint trap or a 4″ In-Line Dryer Lint Trap.
The most durable type of exterior wall vent cover is the type made of metal with a magnetic door or damper that remains closed when the dryer is not in use.
Vent elbows are available which is designed to turn 90° in a limited space without restricting the flow of exhaust air. Restrictions should be noted in the inspector's report. Airflow restrictions are a potential fire hazard.
Joints should be secured with metal tape (not duct tape). Do not use rivets or screws in the joints or anywhere else in the duct as these will encourage lint collection. Length of concealed rigid metal ducting shall not exceed 35 feet (25' for IRC).
Per the requirements of the International Residential Code, Section M1502 (2009-2021 IRC), the clothes dryer exhaust duct should be a rigid or semi-rigid metal duct made of galvanized steel or galvanized aluminum with a smooth interior finish and a duct diameter of 4 inches.
In situations where outdoor venting is not an available option, the vent bucket serves as an efficient indoor solution. It collects lint and moisture, ensuring they do not disperse throughout your living area. It is particularly convenient for apartments or temporary setups.
flexible ducts hoses - metal or plastic - create more frictional drag than rigid ductwork with its smoother interior walls. That reduces the flow of exhaust air, increases drying time, increases energy consumption and can cause more lint to fall out in the duct run, which in turn can be a fire hazard.
On a front load dryer, the lint screen is usually inside the door in front of the dryer drum or on top of the dryer in front of the controls. Top load dryers may have a lint screen inside the door or on top of the dryer in front of the controls, as well.
3. They help reduce lint. When you use high-quality dryer balls made from wool they will help reduce the amount of lint on your laundry items. This is because the balls help to keep your laundry items separate during the drying cycle which reduces friction and as a result creates less lint.
Don't try to use your dryer without the lint filter because this may also cause a fire. Your dryer needs this so that it can work properly. This will ensure each dry cycle will be much less of a fire hazard and will dry your clothes faster and safer.
Rigid Metal Ducting: Rigid metal ducting, such as aluminum or galvanized steel, is widely considered the gold standard for dryer vent systems. These materials are non-combustible and can withstand high temperatures, reducing the risk of fires.
In the United States, most home inspectors refer to the International Residential Code (IRC) M1502 for dryer venting. However, some states may have additional regulations. The International Mechanical Code (IMC) 504 also includes extensive clothes dryer requirements.
Although dirty, this break allows heat and moisture to escape and limits your immediate risk of a dryer fire. PVC piping will not do this which leads to water pooling and severe clogs. These clogs will cause your dryer to overheat and become a potential hazard.
Metal tape can also be used to secure the flexible aluminum duct, too, but clamps make it easier to remove the tubing for cleaning. Aluminum foil duct is inexpensive and relatively easy to work with, but its ribbed walls can trap lint, a potential fire hazard.
If the dryer is against an exterior wall that is not underground, run the duct straight out from the back of the dryer. Set the vent a minimum of 12 inches above the outside ground. Note: This is the simplest, most ideal solution. The shorter the distance and fewer the turns the better for dryer vent installation.
