Wet LPG?
We've got a new Dethleffs Esprit which has been fitted with LPG. We've had it 8 weeks or so and the gas burners have been getting progressively harder to keep lit. They light easiely but won't keep going once the starter knob is released.
A serviceman in Poland (some translation problems) has suggested that the LPG in the bottles is Wet and a build up of moisture is causing the problem.
We've only filled the bottles once (at a BP in Rye) so any water (if that is the case) could only have come from the BP fill or have already been in the bottles ... when we bought the van the bottles were so we filled them for the first time. Has anyone else come across this?

If you have separate gas bottles such as Calor propane 6 or 3.9 kg, then try substituting a known good, full bottle & running that for a while. after a few minutes you should have known, good gas in your pipe work
and you will know if :--A ) it is your Appliances or regulator
B ) Your gas supply
C ) Your Polish translation
!!Sorry I cannot be of more help, but I cannot find an advert with your 'vans details, is it very new ??

Nearly fell out of bed laughing last night 'cos I suddenly realised what this thread is titled
.Dammit, of COURSE your gas is wet -- It's [ giggle giggle ] LIQUIFIED PETROLEUM GAS !!
So it's bound to be wet, until its all evaporated, is it not.
I didn't know that Poles were renowned for their sense of humour

The way I read the OP's post is that he is using a refillable cylinder or filling a standard cylinder. For refillable cylinders they are filled to 80% for the liquid to turn to gas, if not and filled to more, then liquid comes out not gas. May be wrong of course.

Also the density of LPG is lower than water, so the liquid gas would float on any water (which I doubt there is), so unless you are travelling and the gas is sloshing about....
I would suspect the regulator - some good suggestions above for step by step fault finding.

The feed from a LPG tank can be wet or dry.
The dry feed is what we caravanners are used to and is taken from the top of the tank where the liquid has vaporised. In cold weather the level of liquid is given away by frosting below the liquified section.
Wet feed is taken from the bottom of the tank and is in fact liquid which is then vapourised outside the tank before use. This is the way LPG road vehicles take their supply.
If a tank was overfilled one could well be getting "wet" from a top takeoff, but not for long.

Thanks for all of the suggestions. The van (and stove) are both new. I took it to a certified Dometic agent today in Gdansk. When I suggested "wet gas" he snorted with derision. I hadn't had a comfortable feeling about the previous service man, so maybe my gut feel was right.
To cut a long story short, the guy in Gdansk fiddled around for 2 mins, adjusted something where the bottles are joined to a regulator valve and its now all go! And whats more he waved away any fee ... so if you are ever in Gdansk and need a serviceman I thoroughly recommend Leszek & Zbigniew Lew on 58 552 1918
