The flexible nature and expandable configuration allow most installs to occur without any modification to the duct or the wall penetration. A pair of jumbo zip ties and you're good to go…at least for a few months until all of the internal bumps and ridges begin to clog with lint.
Most folks use clamps or metal foil tape. Metal foil tape is good at handling the heat that your dryer will produce. Connect the elbow joint if necessary to navigate any turns or go upward. Run the metal duct pipe from your dryer to the hole you've created. Avoid kinks and tight turns which can trap lint.
CAN TIES GO IN THE DRYER? Ties should not go in the dryer.
Use a screwdriver to tighten the vent clamp and give it a slight tug to ensure it's securely in place. Then, connect a second vent clamp to the opposite end of a vent hose, connecting the vent to your dryer exhaust and using a screwdriver to tighten the clamp.
Dear Pat It is very important to install a tight-sealing dryer vent cover for several reasons. The dryer vent duct is a direct open path from indoors to outdoors. If the vent cover does not seal well, it is just like leaving a window partially open.
The flexible nature and expandable configuration allow most installs to occur without any modification to the duct or the wall penetration. A pair of jumbo zip ties and you're good to go…at least for a few months until all of the internal bumps and ridges begin to clog with lint.
Avoid using standard cable ties in HVAC applications without considering their temperature resistance. Using ties not rated for high temperatures can lead to premature degradation and failure, compromising system integrity.
Cable ties, often referred to as zip ties, are single use fasteners that help keep cables and wires secured and orderly to prevent damage and limit movement.
Different materials used to manufacture zip ties have various temperature tolerance levels: Nylon 6.6: This is the most common material for zip ties. It generally has a temperature range of -40°F (-40°C) to 185°F (85°C). However, it can get brittle at lower temperatures.
The dryer can be damaged by zips or zipper teeth jutting out and catching the sides.
You can wash and dry neckties at home by using a gentle or delicate cycle on your washing machine or by cleaning the ties by hand with a mild detergent. It's recommended to air dry after washing, as tumble drying can damage the lining or fabric of the tie.
DO NOT terminate dryer vents in crawl spaces or attics. Dryer vents that terminate in crawl spaces or attics allow for moisture to deposit and encourage mold growth and health hazards.
Foil duct is held in place with dryer clamps or large hose clamps. Metal tape can also be used to secure the flexible aluminum duct, too, but clamps make it easier to remove the tubing for cleaning.
Secure Vent Hose with Clamps
If your vent hose repeatedly disconnects, it's likely due to loose vent clamps. Use clamps to tightly secure the vent hose to both the dryer and the vent opening. Ensure a snug fit to minimize the chances of the hose coming off.
Plenum rated cable ties are typically made from high-quality materials that meet the specific requirements of plenum spaces. These materials are carefully selected to ensure that the cable ties can withstand the unique challenges posed by these environments.
Secure Vent Ducts
Use a carpenter's level to ensure the runs slope slightly toward the vent exit. Attach hanger straps to support the duct, if necessary. Use foil tape wrapped around seams to seal connections.
Duct Ties are made from nylon in two sizes: 36″ for 10″-15″, and 48″ for 15″-20″. Featuring a head design that easily accepts the strap end and requires low insertion force, these straps provide 225lbs. average loop tensile strength for secure installation. UL recognized, Duct Ties are packaged 25 per bag.
Cover your dryer vent hole with 1⁄4 in (0.64 cm) hardware cloth. Hardware cloth is a type of sturdy, galvanized wire mesh and 1⁄4 in (0.64 cm) hardware cloth means that it has 1⁄4 in (0.64 cm) openings in the mesh. These spaces are small enough that even tiny critters like mice won't be able to get through the cover.
Dryer venting tips and practices
Flexible transition hose between the dryer and the wall outlet should be either the foil type or the aluminum flexible duct (most preferred). Do not use the plastic or vinyl. Concealed ducting must be rigid metal (galvanized or aluminum) duct.
Exhaust ducts shall terminate on the outside of the building or shall be in accordance with the dryer manufacturer's installation instructions. Exhaust ducts shall terminate not less than 3 feet in any direction from openings into buildings. Exhaust duct terminations shall be equipped with a backdraft damper.
Loctite Extreme Glue is a super versatile adhesive that is perfect for sealing dryer vent pipe leaks. The high-viscosity and permanent flexibility make it resistant to vibration, moisture, heat, and UV light.
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.
Longer Drying Times: A dryer without proper venting struggles to remove moisture effectively. This means your clothes take longer to dry, leading to higher energy bills and potential damage from over-drying.
