Shouldn't that read: Open Valve B and close valves A and C, or am I missing something here?
Sounds much like you say Jonathan. One of the things you can do is look at the water lines to and from your water heater (assuming that you can see them). Normally just looking at the lines, the positions of the bypass valves, you can visualize what is going on. Assuming the handles have been installed correctly, you can see how valves cut off the water going through the tank, and the other one opens a "bypass" that routes the water around the tank.
It's really pretty easy to figure once you look at the entire assembly. The key is getting the view. My '01 Safari was a piece of cake since the bypass assembly was viewable from an outside storage compartment. In the Classic its underneath the sink accessed by a small door. Much more cramped and difficult to fathom.
