I am having problems with the LP gas system in my caravan. Sometimes, usually in colder weather the gas cooker will not light. In hot weather it works fine. I rang the manufacturer (was under warranty then) and was told its a world wide problem caused by contaminations in the gas fouling the regulator. I have changed the regulator but it just occured again. Has anybody else had this happen or is the manufacturer pulling the wool over my eyes.

Hope someone has the solution.

This problem is a bit like asking the pollies why the trains don't run on time - its the other bloke's fault.

The only scrub around seems to be to place the regulator higher than your gas bottles, and preferably (though I cannot see how this would work) do not use flexible hoses to connect to the bottles, as the allegedly contaminated gas will make the allegedly inferior rubber in the braided hoses deteriorate.

I was lucky - my van dealer put a new one in for me, and 2 1/2 years later it has not failed so I have done nothing about it. But the first one failed on a freezing cold June night like your experience.

Its a disgrace, but lifting the regulator seems to be the only solution.
Good luck

Some LPG has a high butane content. Try not to top up a half empty cylinder as the butane content builds up in the bottom of your tank. I always run mine out as far as possible and then (in a safe place) vent off any remaining gas to totally empty the tank before refilling. Try and get as high a propane content as you can, I think that you will find that you can only call cylinder gas 'propane' if it contains at least 80% propane. The rest of the mix is nearly all butane (as in cigarette lighters) and does not 'boil off' as a gas easily when cold. A major supplier should know what the propane content of each delivery is so ask next time you get a fill.

Try tipping a bucket of warm water over the cylinder, this has worked for me.
Old plumbers trick.

If you havent got hot water leave a sugar bag or old blanket rapped
around the cyclinder. NOTE TEMPORARY FIX ONLY.
