Can a Vent Pipe Be Run Through the Side of the House Wall?

Running Through House Walls

• If you are worried about running a vent through a house wall, you can probably go ahead with the project with the right preparation. Vents are run through house walls on a regular basis, both to access chimneys that are located in other parts of the house and to immediately access outdoor air. But you will need to make sure there is no plumbing, wiring or studs in the way before choosing the location for your vent.

Vent Kits

• For some projects, you can even buy a vent kit that helps you install a vent directly through the wall. These vent kits are useful if you are installing a stove near an outer wall, since you can save money by venting right out the wall. The kit includes the necessary pipes, flanges and attachment materials for your work. Use a pipe that meets all necessary building and fire codes for your project.

Sealing

• Vent sealing is one of the most important factors when installing a vent through a wall. Chimneys are built to channel air, but if you are going through a wall, you need to make sure that the space is properly covered up so air cannot leak in from the outdoors. The properly flanges and liners will help with this process, but you may also want to add foam insulation as well as a layer of waterproofing caulk around the vent.

Requirements

• In addition to using the right type of vent, you also need to make sure that the vent extends through the wall properly. The vent needs to be at least 24 inches from the ground and at least a foot away from the outside wall, which will help prevent soot and staining from exhaust. Consult your local building codes for details, since this type of installation above several thousand feet might not work.
