The "prohibition" on using adapters is aimed at people filling standard locker based propane bottles not fixed tanks. So relaxAlready one of these fitted to our 564 when we bought it, I think this may have been as standard on the this model as there is no cupboard to store a bottle.
wouldn't b without it but wherever you buy it from discuss what sort of filler valve you have.
Ours is a universal fitting using adaptors, lpg gun fittings are different in almost every country but there seems to be an upward trend in this country of filling stations displaying signs on LPG pumps saying you cannot fill using an adapter.
I am reliably informed it is to do with their insurance but if it becomes universal in the UK it could cause problems in the future.
Unfortunately the staff at the sites I visited did not appear to understand this as it was applied as a blanket ban on adaptors which the staff took to meaning all adaptors.The "prohibition" on using adapters is aimed at people filling standard locker based propane bottles not fixed tanks. So relax
