Water Heater

I purchased a 2010 Cardinal 3450. I cannot find information about the valve positions. Hence I do not know whether my water heater is in a by pass mode or not. This is a picture of the rear of my water heater. The hot water in-valve is obscured by another water line but the other two valves can be seen. The cold water valve is parallel to the water line, and the vertical by pass line (I assume), is just the opposite. The upper hot water valve is set as the lower cold water valve. Which is the open position; valve handle parallel to the water line?
Thanks for help..

As pictured, the valves are in the normal operating position. To winterize it you simply reverse all three valves from their current position.

Valve is open when parallel to fitting, closed when perpendicular (90 degrees) to fitting. Looks like you're all set for camping.
