As shown in the attached 1960 Accessory Installation pages, the economy heater included no shut off valve from the factory. Most of the early installations I have seen used a mechanical valve that turned on and off like a water faucet. This was mounted in one of the heater hoses on the engine side of the firewall. On in the winter, off in the summer.

It’s not uncommon to find a cable operated valve installed either. Any local parts house will have many to choose from, it’s simply a matter of finding a configuration that is most convenient for the setup, and making sure the valve either pushes or pulls to open so it’s plumbed in correctly. A universal choke cable completes the system.

On my truck I use a vacuum operated valve with an electric/vacuum solenoid so I can open or close the valve with the flip of a toggle switch.

Here are the pages from the Accessory Manual:
