Hi Bob, You need the following parts from BES: Gaz adaptor - 16643 - only this one will work, normal Gaz regs do not work for home fill. Calor 27mm clip on adaptor - 17917 - again, calor reg will not work, has to be the BES one. Hose assembly - 16712 and thats it. Connect the two regs to each other using the hose. Attach the calor reg to big blue bottle and invert bottle. With Gaz reg unattached open its valve until liquid gas emerges. Then close valve and screw into empty gaz bottle. OPen valve and you'll hear the gaz bottle filling. It works a lot better if you put gaz bottle in freezer for an hour first. Using ACCURATE scales keep weighing gaz bottle as it fills. When it gets to 6kg its full (usually 20mins to half hour for me). Technically a full one weighs 6.5kg but after the 6kg mark the filling process goes so slowly that I don't bother. Whatever you do, DO NOT be tempted to fill past 6.5kg. Liquid gas needs space to boil off. And obviously, you do all this OUTSIDE!!! I know thats stating the obvious, but I have to mention it.
Fred I thought I'd get a H&s rebuff from the forum so posted it for the devilment. I have a valve which screws into the 907 and hopefully the donor butane cylinder can I ask what else is needed? Regards Bob
