I am having a new Carrier 58MVC80 installed to replace my conventional chimney exhaust furnace located in my basement. They are going to run new PVC thru the adjacent basement wall.
The problem is that I am planning on extending my deck to cover the same area they will need to place the exhaust. There are limited options in the basement for placing the exhaust due to the layout.
I know they cannot have the intake/exhaust under the deck, but is it OK to extend those PVC pipes by 10 feet from the wall of the house and vent on the outside of the deck? Or is it OK to run a 90 degree elbow once the PVC exits the wall and run the vent pipe down parallel to the wall so they terminate beyond the deck?
Thanks in advance!!
