Have you verified the hot water tank is filling with water? You can do this by connecting to a city water source and then opening the pressure relief valve on the water heater. Be careful because the water could be hot.
Page 137 of the 2014 version of the owner's manual has a diagram of the by pass valves. In normal use the valve handles on the two lines going into and out of the tank should be in line with the hoses. The handle on the by-pass line (line running between the two hoses) should be perpendicular to the line.
The diagram in the manual shows all three valves open. For normal use the valve on the by pass line should be closed.
Often times when a dealer de-winterizes they do not place the valves in the operating position.
