Hi how old is you van? or do you have a regulator already fitted to the van or do you have the regulator fitted to the gas bottle and a hose then to your van .If the regulator is fitted all you need is new propane tails from the bottle to the regulator , if the later you will need a propane regulator , this will not affect the use of the cadac , i think prpane has a lower calorific value but could be corrected.
Karl,
Mike is right, the major difference between a Propane and a Butane bottle is the bottle connection itself.
If you have a Cadac Global Grill or Skottel, with say the 30 millibar jet, then it should work on either gas as long as you have a 30millibar regulator (or 28mB at a pinch).
Butane has a boiling point of -0.5

Big Roy,
One of the delights of France are hot days (and the food and the wine and...) but when the temperature hits 40
Hi rob-jax & Big Roy
Just a bit more information, Propane bottles with theh "Pol" connector (L/h screw-in type)supplied by Calor has a pressure relief valve fitted into the stem of the bottle valve. This is another essential reason why gas bottles must always be stored moved or ued in the upright attitude.
It may not be the same for other manufctures bottles.

When you change from butane to propane - not all Calor dealers will allow it.
Although there is no public distinction, many Calor dealers are just "resellers" and won't allow cylinder type/size swaps. This includes many caravan dealers!
Check out your usual Calor dealer BEFORE you need to swap.
If you have problems try Calor Direct, get their number from Yellow Pages.

Interesting comments on propane use. Please tell me why do all French filling stations store propane bottles outside in the sun if there is a problem. I have used (French) propane for over 20 years mostly in the south of France and have seen 40 degrees on many occasions. I have never been aware of any venting of excess pressure in the gas locker and I do have a gas alarm fitted. Whilst there seems no reason to doubt the technical specifications quoted and I haven't checked them (yet) I cannot believe the French petrol companies would allow storage of bottled propane gas if was as dangerous as claimed.
Further to my previous comment. I have now checked my propane bottles. They have a test pressure of 30 bar (450 psi) stamped on them. My Calor reference book gives bottle pressures as 1.72 bar for butane and 6.21 bar for propane at 15 degrees C (25 and 100 psi in old money). The previous reference to 90 degrees C is a bit misleading as I am sure it could not be achieved under any circumstances likely to be met whilst caravanning including very high ambient temperatures and is a reference temperature at which problems may arise.
The Calor website specifies the groups of gas bottles (size / type) which can be freely exchanged BUT many Calor dealers, including CC wardens and caravan dealers, DON'T operate this exchange.
The reseller all sign the same one page contract with the same 'open to interpretation' statement about bottle changing. If you go to Calor direct they will swop any of the two smallest bottles between each other, so why don't they make it as simple for their resellers to understand and stop all this nonsence.
Further update on propane bottle pressure. At 110F (43C) ambient the gas pressure is 204psi well within the test pressure of the bottle. The U.S.A is virtually 100% propane usage for all purposes and has very high temperatures in some states. However, they are now fitting overpressure relief valves to gas bottles for fire risk. It is safer to vent and burn the gas than have bottles explode in a fire.
