How to mount a Dryerbox in a CBS block wall
« on: August 31, 2012, 09:05:42 AM »

My engineering firm specs your dryer vent box whenever dryer vents are located in stud walls.  We’ve had a lot of commercial situations where the dryer is located against a block wall.  We usually have the contractor install the vent in the block wall.  We’d like to have the contractor use a dryer vent box in the block wall, but aren’t sure it’ll work.  Do you have any experience will that?  Or do you have a product designed for block wall use?

Good question.

There are really only two options, and neither are that great. 
The first is to work with the block mason and make sure he knocks out the block and webbing creating a recess or "soap" in the blocks behind the Dryerbox.  Remind him the wall is single or double firred so he only removes what is needed.   He will need the Dryerbox supplied with a short ~6 inch nipple coming out of the top and going into a 90 ell.  Once he gets this assembly to fit, you or the mason could foam the opening, then block it off with plywood, and let the area around it get filled with pump mix. 

The attached PDF document (drawing) is very helpful and has a nice instruction note:

The other option is to build or create a full height or partial height stud wall in front of the masonry wall that would hold or encompass the dryerbox and the exhaust conduit. 

Hope this helps, and if you do either, I would really appreciate a picture for the forum thread.  Thanks again for asking.
