Dryer Venting ??

Iam in the process of building a new home on a slab.The house will be 3-4 blocks off the ground. The foundation has not been started yet. My dryer in located on a interior wall. (hallway) What are my options for venting my dryer. The walls are 2x4 construction. Slab ventation is a option....But what materials? PVC ?? I guess I could go up to the attic and out the side of my gable end ?? Dryer vents are 4" pipe. How will this work in a 2x4 wall? 2x4's are really 3 1/2 ?? Any Ideas ? Anyone else here have a dryer on the interior wall..And how is it vented ? Thanks

They make a square metal duct for dryers to vent up the wall which fits inside the 2x4 framing. Once in the attic you could convert to round pipe if desired and vent out of the roof or gable.

The installation guide for the dryer should tell you the maximum vent length ,including 'els' ,that is allowed. Obviously ,the shorter the better. PVC is not a good choice for dryer venting as it is susceptible to static which tends to cause lint clogging.

Wink

If the 2X6 wall will mess you up . A sheet metal shop can make you a 8"x3 1/4" duct to slip in to the wall up to the attic there. use 4 " smooth metal pipe. To the outside roof or over hang dont let it out in attic.

Or just use 1x2 furring strips on the wall that the 4" round vent will go through.


Also remember that you can only use rigid pipe in the walls, sections should be taped and not screwed together as the screws will provide a place for lint to collect. Most codes also allow a maximum run of 25ft or the dryer manufacturers spec. So if the manuf. says 50ft you can run it 50 ft even if code only calls for 25. Also any 90's are the equivalent of 5ft and i think 45's are 2' or 3'.


There is a company that makes a long sweep 90 that will eliminate the 5'ft per 90 if total run is gonna be a problem. They also make a very nice box that you add into the framing that allows for a nice clean transition from the dryer to the rigid pipe in the wall.
