hi gemm,

the adaptor will only fit propane (red) i think, i would advise only using propane as it doesn't freeze in colder weather unlike butane. the person who bought our 'van bought one from ebay and it arrived quite quickly. when you say it was fitted with a red bottle when bought, was it not connected?
btw it is well worth paying the tenner to subscribe.

YOUR German reg will fit a French /Spanish/ uk propane bottle ? for the uk one phone truma They will post you the adapter to fit uk propane bott.

Just to make life a little more complicated here's a description of my scenario which I am still trying to understand.

1992 Hymer Camp 55 ( German import )
Grey 11KG Propane cylinder
2 regulators
- first one connected to cylinder looks like :

- the second regulator is inline with the first i.e. it feeds the van but is not currently attached to a cylinder :

The complication is that I live in Spain. Here I have very easy access to 11KG butane cylinders but they use different clip-on regulators with a normal pressure of 29 mbar for our household appliances.

The documentation in German for the van appears to indicate that you can use propane or butane. It also says that in Germany the setup MUST be run at 50 mbar. However it is not clear whether the appliances ( fridge, water heater, gas heater ) will operate correctly at different pressures.

It also seems logical to assume to red reg marked reserve is for a second gas bottle, but why does it appear to have a different flow rate 0.8 KG/hr instead of the 15 KG/hr of the green reg ?

Any advice whatsoever appreciated.

Cheers

Dave

re HYMER 55/ You only need a spanish freeflow valve which looks just like a regulater but is not,(valvula libre) this fits your german 50mb Reg connection, (screw) you are talking about lightweight cepsa bottles 11kg ? you can use Repsol orange as your reg will not fit over the valve guard on the cepsa bottle, your german reg also fits a french bottle , ask at your local Repsol dept for valve / and orange s/h bottle can be bought from carboot -25€

red and green

This is the truma auto change over system which works when a bottle is empty .one has slightly lower flow to read as an empty green -main red -standby.

Thanks so much for your advice. You are correct that I currently have Cepsa lighweight butane bottles for use in my house.

If I can just replay my understanding of everything to you which I have gleaned from this, and many other sources :

1> I can use either butane or propane with my appliances. The only real difference is that butane is reluctant to turn to gas at sub-zero temperatures, and appliances will therefore become less and less effective, until presumably they stop working completely, as the temperature drops below zero.

2> I can buy an adaptor from my local Repsol agent called a "valula libre" which will allow me to connect a Spanish Repsol ( Orange ) butane bottle to my German regulators. Cepsa bottles won't work as they have a flange at the top which would prevent the connection to the regs.

3> If I connect 2 same size bottles in parallel via the installed regs the different regulator outputs will cause one bottle to empty much faster than the other providing plenty of time for a changeover, before the second bottle runs out.

Thanks for any further feedback, and I'll be sure to update the board with my progress.

Cheers

Many Thanks swampy glad Icould help. Propane is most commonly uesd as normaly it does not get below 5/6c , well not here anyway ! but we feel cold when it does (time to Light the fire) but we have for many years carried a 2/burner camping gaz stove/bottle and cook outside van , when we set up camp . happy travels Buen viajes!
