Once you have the exact installation configuration, measure, as there are different sizes. I did a direct wall install and horizontal vent with the appropriate pitch and only needed the 223181—effortless install and Perfect.

Easy to install, little bit of a change in how it delivers hot water vs tank. Had a 50 gal for 17 years, hope this lasts me just as long or longer
