I assume this is the “relief” valve flow diagram by Roadtrek. Truma’s manual clearly shows how a pressure relief valve should be installed so why would they approve a different and unsafe installation.
A first boom-boom malfunction and Roadtrek could be in a deep trouble and will not be able to say we didn’t know.
BTW: this is a similar photo that depicts Aktiv water flow from input (1) to cold water input to boiler (10a). The boiler explosion hazard is cause by the brass over-pressure valve (near 7b) and yellow drain valve (near 7a) being isolated from the boiler (after 10a) when the owner puts the bypass valve (near 9) in bypass, a common event. In the bypass position the two safety valves are diverted from the boiler and the boiler is sealed.
