I have stumbled upon yet another peculiar engineering design choice. This one I cannot explain as anthing other than a deliberate and studied inplimentation with the sole intent to defraud.
Whereas the previous choices might be explained by oversight, or ignorance I see no way to justify this one. It would be easier in terms of cost and labor to route the outlet of the E-car off the top of the chimney. The peculiar choice to route it out of the side means customizing parts as best I can tell. Search among the suppliers of copper pipe fittings. If anyone can find evidence that reducing "T" such visible is the photographs of the Ecat is manufactured by anyone, let me know. Routing out of the top would require only a couple of pipe reducers and an 90 degree elbow. This choice would not allow water in liquid phase to weep out the exit. Placing it on the top would mean the water would have to rise into the elbow at the top before weeping over into the outlet hose, making it far more difficult to explain to the critical eye.
