Use only 4” rigid metal ducting for the home exhaust duct. Use only 4” rigid metal or UL-listed flexible metal (semi-rigid or foil-type) duct to connect the dryer to the home exhaust duct.
Does a gas dryer need a special vent?
Gas dryers must always be vented.
When gas dryers are running, the combustion that takes place inside produces carbon monoxide, which must be vented either outdoors or into a suitable HVAC ventilation system. Most electric dryers also require venting to keep from blowing hot, moist air into the home.
What material should a dryer vent be made of?
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.
What can I use for a dryer vent?
You can use a 4-inch flexible aluminum foil duct that is UL 2158A listed and marked for safe dryer venting. Look for a product that is constructed from heavy duty, fire resistant aluminum foil with a high density, corrosion resistant wire helix. Remember that only ducts 8 feet or less can be UL listed and marked.
Can gas dryers use foil vents?
Like vinyl ducts, these ducts impede airflow and trap lint. Aluminum foil won’t burn, of course, but it will quickly disintegrate in a fire. Dryer manufacturers don’t recommend foil ducts and neither do we.
What is the best way to vent a gas dryer?
It’s best to route the dryer vent in a horizontal path to the home’s outside wall. All horizontal runs should pitch 1/4-inch per foot to the outside. This will help to avoid moisture from sitting in the pipe or draining back to the dryer.
Does a gas dryer need to be vented outside?
Warning. Since gas dryers produce carbon dioxide as a by-product of combustion, they should always be exhausted to the outside. Outside venting is also important to prevent the exhaustion of water vapor from damaging structures or causing mold and mildew growth.
Can I use galvanized pipe for dryer vent?
Dryer manufacturers recommend using rigid steel tubing for dryer vents. Both aluminum and galvanized steel work in these applications. Plastic and flexible tubing can be less efficient and can actually trap lint, which can decrease the dryer’s efficiency and can be a fire hazard.
Can PVC be used for dryer vent?
Dangers of PVC Pipe
PVC pipe’s sensitivity to heat is a big reason why it is not recommended for use in dryer vents. The exhaust from a clothes dryer can reach temperatures ranging from 120 degrees to 200 degrees Fahrenheit, which could cause the pipe to soften and fail.
Are aluminum dryer vents safe?
Only rigid metal ducts, either aluminum or galvanized steel, are suitable for concealed dryer vent ducts that run inside floors, walls, and other areas before venting outside the home. Their smooth surfaces allow maximum air flow and resist lint accumulation, which contribute to fire safety.
What is code for a dryer vent?
The maximum length of a 4-inch (102 mm) diameter exhaust vent shall not exceed 35 feet (7620 mm) from the dryer location to wall or roof termination, and shall terminate with a full opening exhaust hood. A reduction in maximum length of 2.5 feet for each 45-degree bend and 5 feet for each 90-degree bend shall apply.
Can you vent a dryer upwards?
You can vent a dryer vertically as long as you don’t exceed a distance of 35 feet in length. The preferred way to vent a dryer is downward or laterally but vertically is indeed an option.
Is it better to vent a dryer up or down?

Can you vent a dryer into a bucket of water?
2: For dryers that are located in a place where venting to the outside is difficult, it’s OK to simply vent the dryer into a container of water.
What type of pipe is used for dryer vents?
That being said, we recommend using a smooth rigid metal duct to vent your dryer. Metal can withstand the heat generated by the dryer, and is will not accumulate dust and lint like plastic pipe. Aluminum duct is usually a safe bet, and it’s fairly inexpensive.

What happens if you can’t vent your dryer outside?
Improper venting of a dryer typically results in moisture being deposited in various areas of the room.
