Hello All, Super impressive install, Michael. Almost worth a flight, and a site visit! Back to Jason's initial question....
If you are using the 15kW Outdoor Sol-Ark they vent from the top and bottom with a required 6" minimum spacing on both the top and bottom. A 12kW Outdoor with 8x8 gutter and 1" offset nipples have worked great for us.
