CHRIS THOMAS Posted May 19, 2023 Share Posted May 19, 2023 Wondering if anyone can advise me. I have blue butane bottles and want to change to red propane bottles. I know i need to change my regulator, but do i need to change my cooker and heating jets. Thank you in advance. Chris Penzance Link to comment Share on other sites More sharing options...
Keithl Posted May 19, 2023 Share Posted May 19, 2023 Hi Chris, We're going to need a bit more info to help you, what year was your MH manufactured and do you have the regulator connected directly onto the cylinder or is it mounted on the bulkhead with a high pressure pigtail connecting it to the cylinder? PS make and model of MH may also help. Keith. Link to comment Share on other sites More sharing options...
CHRIS THOMAS Posted May 19, 2023 Author Share Posted May 19, 2023 Hi thank you for your reply. It's a 2002 Peugeot Boxer Compass Cruiser. The regulator fits straight onto the bottle Link to comment Share on other sites More sharing options...
Keithl Posted May 19, 2023 Share Posted May 19, 2023 Thanks Chris, The regulator swap will be the easy part, undo the worm drive clip and pull the regulator out of the hose then fit the new one. The difficult part is working out if your appliances will work on propane at its slightly higher operating pressure. Butane regulators operate at 28 mbar and Propane at 37 mbar. If you have the original instructions for the fridge, stove, etc. then these should detail gas supply requirements or search online for copies. If not then try looking for the manufacturers rating plate on the appliances. I would hazard a guess they will all be ok but you really do need to check. Keith.

david lloyd Posted May 19, 2023 Share Posted May 19, 2023 I thought that on these type of gas systems (prior to bulkhead fitted regulators) that the appliances worked on either butane or propane providing the correct (propane or butane) regulator was connected to the gas cylinder - i.e. the appropriate regulator ensured the operating pressure was correct for the type of gas being used.

Derek Uzzell Posted May 20, 2023 Share Posted May 20, 2023 This 2015 Practical Caravan article may be helpful https://www.practicalcaravan.com/advice/how-to-get-the-best-from-your-gas-bottle-regulator The gas appliances originally factory-fitted to a 2002 UK-built motorhome will have been designed for a gas-pressure range of 28-37mbar and will have had labelling on them to confirm this. (The fridge should have had a 28-37 adhesive label inside it. Whether it would still be readable after 21 years is another matter.) Link to comment Share on other sites More sharing options...

CHRIS THOMAS Posted May 21, 2023 Author Share Posted May 21, 2023 Thank you all for your replies. I have the original booklets so i will check. Thank you, Chris Link to comment Share on other sites More sharing options...
CHRIS THOMAS Posted May 22, 2023 Author Share Posted May 22, 2023 Hi all. I have checked my booklets, the cooker and heating system will indeed work off both butane and propane the fridge says refer to the indentation certificate / plate. Attached below is what i found inside the fridge. Wondering if you could kindly advise me. Link to comment Share on other sites More sharing options...
onecal Posted May 22, 2023 Share Posted May 22, 2023 Hi Yes it should operate fine within that range Regards Link to comment Share on other sites More sharing options...
Keithl Posted May 22, 2023 Share Posted May 22, 2023 Yes I agree with OneCal that you should be ok. The label clearly states LPG with a pressure range of 28 to 37 mbar so covers both gases and appropriate regulators. Link to comment Share on other sites More sharing options...
CHRIS THOMAS Posted May 22, 2023 Author Share Posted May 22, 2023 Thank you, at least i now know i can change over to propane. Really appreciate everyone's input Link to comment Share on other sites More sharing options...
Derek Uzzell Posted May 23, 2023 Share Posted May 23, 2023 The basic advice is as follows: Until September 2003, caravans and motorhomes used a different regulator depending on which gas was being used to provide the appropriate operating pressures, 28mbar (millibar) for butane and 37mbar for propane. Some units from continental Europe use different pressures, up to 50mbar. Since September 2003 a European standard (EN 1949) has made the supply pressure the same for both gases throughout the EU at 30mbar. While pre-2003 units still require different regulators depending on the gas used, all current UK-built caravans run at 30mbar, and this figure should be marked in the gas locker near to the regulator. I started motorcaravanning in 1999 and it was then common practice for owners of UK-built motorhomes to use butane bottles in the summer and propane bottles in the winter, and to swap the on-bottle regulators to match. I recall using butane initially (as the secondhand motorhome I had bought came with a butane bottle) but - after I had noticed the the gas hob's burners 'sooted' badly - I was advised to use propane instead. Although sceptical, this did in fact stop the sooting.

Keith. Just on this, if there is any chance that that hose (or "pigtail") is the original, I think you'd also be wise to change it. I know its not a high-pressure hose, but they all deteriorate over time, and pulling it around to detach the old regulator and fit the new one is likely to test its resilience - with unpredictable consequences!

onecal Posted May 24, 2023 Share Posted May 24, 2023 Hi Brian Very good point as they are stamped dated and should be changed every 3 to 5 years unless they are stainless steel of course Regards Link to comment Share on other sites More sharing options...

I know its not a high-pressure hose, but they all deteriorate over time, and pulling it around to detach the old regulator and fit the new one is likely to test its resilience - with unpredictable consequences! When an on-bottle gas regulator was fitted to a UK-built motorhome/caravan, the hose between the regulator and the leisure-vehicle's metal gas pipework did not need to be the high-pressure type. If low-pressure (black) gas hose was used, it was recommended that this be replaced annually and - when a motorhome/caravan had a 'professional' annual habitation service - low-pressure hose replacement was standard practice. Many motorhome owners who DIY-serviced their vehicle's gas system chose to use instead high-pressure (orange) hose and replaced this less regularly. (I remember that, for a while after the 2004 UK standardisation of a bulkhead-mounted 30mbar gas regulator and a high-pressure gas hose ('pigtail') with threaded end fittings, some motorhome/caravan dealerships carrying out annual habitation servicing insisted on replacing the (quite expensive) pigtail during the service as hose replacement had been what they had always done in the past.)
