Help with connecting this Heater.........
I have been redoing my 1969 trade wind from scratch. Now its time for plumbing. Bought this new heater from c.list. Could be a demo . Just need to know how to connect the water lines.
If I am not wrong, bottom is the cold line and top is hot. But if you see in pics there is some kind of a valve on top with two outlets. The red knob on it does not turn left or right. So I am confused how to connect.
thanks in advance.
