My propane heater will not stay lit. If your propane tank is empty or your natural gas line is cut off. If the unit is brand new adjust the thermocouple nut.
The problem may be a genuine defect or it could be an issue with the sensor.
Answer 1 of 2. Check for a gas leak. Patio heater flame is. If the patio heater has an electronic ignition system make sure that there is a spark.
