Jim, I note your comments but having spent many years in the LPG business and investigated a number of serious LPG related incidents, I am proffesionally and moraly bound to exercise and recommend caution. Paul does not state the age of his caravan, & therfore we cannot know if he has the old imperial, Uk Metric, or the EU harmonised equiepment. Some of the older equiepment is sensitive to both type and pressure of gas supply and if fed with the wrong supplies may become unsatable and begin to emit excessive Carbon Monoxide. The use of 37mBar propane regulator on equiepment rated at 30mBar Butane/Propane can take the appliabcnce just outside of its approved rating, and as such insurance companies may decline any claim, as the appliance has been used incorrectly. By haveing the system checked by an approved fitter these varianece can be avoided.
