Propane is liquid in your tank. The vapor pressure will depend on the temperature as you can see by the following chart. For an example at 0F the vapor pressure in the tank would be 24.5 psig. and at 90F it would be 150psig. This is why you draw vapor from the top of the tank and then go immediately go through a high pressure regulator. Then usually at the appliance there is also a regulator (sometimes incorporated in the safety valve) You are burning propane as a vapor not a liquid. Remember for safety that propane vapor is heavier than air and sinks to the floor, so one must be careful for proper ventilation.

remove and refill the gas ? it should hold 750grms of gas and i think yours only has about a 150 grms in system ,if R134A expensive put some propane in as that works better .R600A is a mix of propane and butane 70/30 but price of that gone up as well now that R134 is like 700 euros for 12kgs ,i mix my own with my machine .But just propane will work ok
check the high-limit switches. Under the inlet/outlet header. if either is open it will not allow you to fire up. my 150 degree switch was corroded and after jump9ng out, bam it worked.
