Hmm, heck if I know what lynch mobs are all about - but all I see here is people helping people who have problems.
Complaining is a good way of making certain folks address your problems - that is, if they don't do so in the standard manner. But after that, it really doesn't do much.
As to this Jotul situation, MSG knows a lot about this stuff - but, just off the wall, can't LP problems also be the result of all kinds of things - like a bad regulator on the LP tanks, etc. - I seem to remember this happening way back in the day. So it seems as if this problem is really not 100% diagnosed (or maybe it has been) - but has the dealer or installer been there and carefully checked the input pressure, burner position and everything else? A tech on the phone is flying blind no matter what....unless the problem is exactly what others have - which does not seem to be the case here.
It's something a bit like medical care - you can get the best doctors in the world, but they often can't figure out what is wrong. The only way is to start at the very beginning and eliminate things one by one - the beginning being the LP tank and regulator, then the lines, etc - when it is established that all that is OK, then you can start at the regulator on the unit itseld, as well as burner seating, etc....
Maybe this has already been done.
As frustrating as it is, you have been given the safest advice - to stop using it until fixed. And, by any measure, that beats "what are you doing, starting it with gasoline" by a long shot!
Hopefully you will be able to get it fixed and live happily ever after....
