Can this unit be mounted in the basement on an outside wall and vented straight up and 90 outside...

Can this unit be mounted in the basement on an outside wall and vented straight up and 90 outside through the basement wall?
Asked by: JErbs2
The unit cannot be mounted on an exterior wall. Home Depot sells a unit that can be installed outdoors. With that said, if you are mounting on a wall facing the exterior in the basement, then yes the piping, which is 2 inc PVC, can be run up the wall and 90 degrees to the outside. Please check the specifications and clearances in the installation manual. If you are not sure after reading the instructions, please have a professional install. I would think the clearances are more important for the proper venting and operation of this product.
