Barely related, we generally use a pair of 11-lb Manchester cylinders which I bought to reduce the Casita's tongue weight
, and to generally facilitate lugging around. They are the same diameter as the standard 20-lb cylinders, so I've been able to mount them on the A-frame of the Casita
and the Escape
by simply dropping the retainer clamps on the all-thread downward. Incidentally, they also work nicely with the "standard" white plastic cover.
Now, here's the possibly interesting parts.
I wanted to get the new cylinders purged, but was stymied by several fill stations that had no idea what this entailed, and another that told me it was too time-consuming. So, I ended up purging them myself. I did this by using the 1-lb fill adapter, with new 11-lb cylinders empty and a 1-lb cylinder that had some remaining propane. After a few repeated cycles of "filling" the larger cylinders with a squirt of gas and then releasing the pressure of the air-gas mixture, I was good to go. It was a very simple operation that took perhaps ten minutes.
Then, when I went to get the new cylinders filled at a station, it emerged that one of the new cylinders was resistant to filling. It would simply stop the propane almost immediately, remaining stubbornly near-empty. One kid unhelpfully banged the bottom of the cylinder on the gravel in an effort to knock loose the internal float valve.
I contacted Manchester and they told me the solution is to have the operator start the fill operation with the cylinder's valve closed
. After the connection is made and the valve from the source bulk tank is opened, you then
open the cylinder's valve. It worked like a charm.
I printed the instruction sheet from Manchester in case someone at a fill station wanted "proof" of this non-traditional approach, but so far everyone's taken me at my word.
Maybe this information will be helpful to someone. I guess this issue is uncommon enough that most attendants don't know about this, but common enough that Manchester has a pre-printed instruction sheet.
