Query: It works if you can get the thing running

I had an original flowtron 150 that worked great but a lightning storm fried the electronic panel and I replaced it with a new Flowtron 150. The newer models have a pressure valve in the gas tubing and I have yet been able to get the machine functioning. The machine is constantly blinking like it is not getting any propane..I have returned two of the new models and nobody seems to have an answer why they aren't working. I know how to run them because I owned a earlier model but this new model needs to go back to the drawing board..
