Propane and natural gas heaters have standing pilot ignition or electronic ignition. If you have a standing pilot ignition you should see if the pilot light stays on when lit and after the valve is turned to the full ON position after lighting. Electronic ignition should light the pilot for you and then the burner comes on - but at the end of the cycle the pilot and the burner go off. If you do not have ignition, check the gas pressure -- 5-7 inches of water column for natural gas and 11-15 inches of water column for propane. Use the pressure noted on the regulator or other labeling. If you cannot test the pressure then contact your gas company or propane supplier for service.

I would change the thermocouple and here is why:
The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close.
Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners

A pressure regulator and pipe or hose. Whoever is selling you the tank/propane should be able to help you size everything based on the tank hook-up and tank pressure. The heater nameplate will tell you the proper inlet gas pressure that the regulator will need to reduce the tank pressure to.

my heater says if the pilot light keeps going off automatically it is a safety function that means it does not have enough fresh air to operate

LOL.... your fuel is not boiling.... the closer propane gets to its vaporization point (-44%F) the less vapor it produces. clean the snow off of the 100# or lay it on its side to give it more surface area for vaporization.

Turn the knob to PILOT. press the knob down. Light the pilot and hold the knob till the pilot stays lit by itself. Then advance the knob to the ON position. Turn up the thermostat.
