I am installing a tankless water heater at the house. My question is unique because I can not find a reference anywhere in the code and the installation manual about where to place my exhaust vent.
I am installing a tankless water heater in the basement. Due to reasons about where the basement floor drain is located and my HVAC duct work, it turns out my exhaust vent will most likely terminate outside next to the stairs for deck. I've attached a picture.
I meet all the requirements for distance from the window as well as the sliding glass door. Also, this vent does not go under the deck so that doesn't apply.
I'm going to install a Rheem flush mount vent termination kit right where the stairs cross the rim joist. This picture shows my location.
What is the general opinion about my setup? It seems acceptable to me, just not perfect.
