From my 83. Turn on main valve on propane tank. Turn on gas at the heater, sould be an in line valve. The heater needs power switched on. In my case the heater under the couch has a toggle switch located near it to supply power. Then set the thermostat to call for heat. A fan in the heater will start up to to begin the cycle, after a few seconds it will light the burner. No standing pilot. When thermostat stops calling for heat it will shut down. Troubleshooting beyond this would involve checking the circuits for power and the flow of propane.
