the heater makes use of a millivolt generator which generates a small dc voltage (500-750mv) that is applied to the pilot valve of your main gas valve. when you light your pilot, the flame bathes the generator with a flame. after a delay you release the pilot button. if the generator is working, the pilot valve will stay lit. if the generator is not working the flame will go out as soon as you release the pilot button. change the generator.

There is a pilot safety called a thermocouple. I bet it needs changing. Look for a small probe that is located in the pilot assembly.

Sometimes when you turn a gas heater off for some time, if the source tank has been turned off, the line will bleed the propane and the line will contain mostly air. This is especially true if the supply line is long. In order to light the pilot, you will have to hold the pilot lighting button down for a while (a full minute or longer, depending on the size and length of the supply line) before pure propane arrives at the pilot light jet. You should keep a lighted lighter at the jet so that when the gas arrives, the lighter will light it. After the pilot lights, you will have to keep the button pressed long enough for the thermocouple to get hot enough to set the pilot to stay on. When it is hot enough, you should be able to release the pressed lighting button and the pilot should stay on. If it does, you should be able to light the heater. If the pilot jet never lights, gas is not getting to the regulator. If the pilot will not stay lit after a period of time waiting for it to heat the thermocouple, the thermocouple or the regulator may be bad and need replacement. :-)
