Dryer vent terminates in attic.

A dryer vent should be vented outside. For medium snowfall zones and or higher profile roof tiles select the larger model 486 which is as efficient but taller. Sometimes such as in town homes or condos it s not possible to vent a dryer through a wall outside. Otherwise rotting waste can cause pressure to build up in the system until it forces it s way past a trap.

No you shouldn t use a towel or other absorbing material. In these cases it may be necessary to vent your dryer through the attic. Insulating the duct may also help. While the manufacturers of aavs say they can be used to terminate your vent stack inside of your attic it seems pretty hacky if you have easy access through the roof.

That is the old material type tubing simply ended by a overhang side of the house where it exhaused into the attic and not outside. You may have a bad boot around the roof vent that is leaking into the attic. The high humid air doesn t vent out of the house before it condensates in the duct and then runs back into the house causing damage. When our dryer was replaced we decided to bring the dryer venting system early 1960 up to code by replacing the tubing that vented into the attic.

This also means that you can t blow the dryer exhaust into the attic or the crawlspace. Terminating the shorter duct run with a dryerjack helps venting through the roof deliver on the promise this shorter route offers. You must terminate your dryer vent outside the building according to section m1502 of the irc. Dryer lint is also highly flammable.

Or you may have a distance issue. So a dryer vent terminating in an enclosed and unconditioned space provides the heat moisture and organic material to create an ideal environment for mold growth. Not all dryers will allow for this so be sure to check the owners manual to ensure it can be vented in this manner. The exterior cover should not have a screen since it will cause lint build up and block the vent over time.

Dryer ventilation systems should only terminate to the home s exterior and have a proper dampered exterior cover to help prevent water birds and insects from entering the duct. Doing so would fill your attic with warm moist air that could rot the framing.
