That was standard I think. There are three ***** in the cab that run heating system. One is supposed to open/close that valve. The second lets air in, the so-called "fresh air" heater. These first two hang down in the middle. The third is the defrost ****, up on the intrument cluster "row". It opens a plenum in the heater unit that directs the warmed air up to the defrost ports, by pulling it out. But it also turns on the heater fan, when turned.
The heater will give you some pretty decent heat by just turning on the water flow and opening up the air. More can be had by using the fan.

I am not certain about whether the fresh air heater (adjustible) was an option or not. My dad got my truck with NO options except a radio, and it has the ***** and adjustible valve. Maybe they made it a standard item somewhere during the year, or perhaps assemlby plants in some areas put them in routinely.
