Dennis...The controls feel connected, but when I slide to the right, it slows down, then moves more easily again, frees up a bit. Mark... The fan control, with I think 4 speeds/stops works fine. Is that what you are asking about? Charles... I will have to look at the FSM to find out what a water valve looks like. And yes, once knowing that, I feel I can use a mirror to try to see if it is hooked up, and able to move. Steve... I don't know if the watercock is the same as the water valve Charles mentioned? As to the heater cable, I'll look in the FSM to see if I can figure that out too. If I have to be a contortionist to view these things, it may have to wait for a more limber person than I. Thank each of you for asking these questions. The more the merrier. Jai
