Hi all you techies out there. Still an amateur and wondering why I can't get any gas to the appliances - checked the taps are on, theres gas in the bottle but nothing coming out. The regulator isn't that old but it seems impossible its the cause, it will be the third one Ive had to change in 6 months. I swapped it with the one on the BBQ and it still won't work. Any ideas? I so want to take off tomorrow but there's always a Murphy in the crowd.
You would have to check the gas line from the bottle to the stove.If there is one it will have some electrical wiring leading to it from the gas detector.If you do have one it will be low down as gas is heavier than air and the detector would be at a low point in your rig.
If not I don't know what to suggest unless there is a gas savvy Grey Nomad who can help further.
G'day guys - well you won't believe this, I took my regulator back to Bunnings and of course they tried to tell me to just buy another one. I then went to BBQs Galore (no great shakes there either and twice the price) and a nice man asked me if I had pumped/pushed the gauge down. 'No' says I, 'Ive turned it both ways but didn't know you had to push it down'. And sure as my A ... points to the ground, that's exactly what it was! Unwucking believable, I have spent hours swapping, returning, connecting, unconnecting, connecting again, and finally someone says 'did you push down the gauge down!' *#*@!! ): bleep, bleep*#@!
So FYI squeeze your gauge down before you do anything!!!
I think he means this one http://caravansplus.com.au/catalog/product_info.php?products_id=640 - you disconnect the gas line from the bottle, screw the gas fuse into the POL thread and then reconnect the gas line. The main function for this device is to cut off the gas flow if there is a serious leak in the gas supply line and the gas flow is above what would be considered normal maximum. The main use for the gauge is to test for system leaks (see the instructions on the link.) The pressure in an LPG gas cylinder remains relatively constant until the last dying throws (ie virtual all the liquid is used) so the gauge is virtually useless in telling you how much gas is in the bottle.
The regulator is normally mounted away from the bottle/s on a van. It is connected to the bottle by a small bore copper line (pig tail) or a flexible hose. You are right about a regulator from a barbecue not being used on a van. The one from a barbecue is a single chamber unit, vans are supposed to have two chamber ones fitted.

Hi cropper - just saw your message but you've been given good advice already. Just for the books, I'm not up with the technical jargon so I may have used the wrong terminology, but the hose from the gas bottle that supplies the bus has what I call a regulator which is a disc shaped sealed unit that regulates the flow from the bottle. You can also buy an attachment that screws onto the regulator that has a round face with coloured segments like a pie chart, and which shows how much gas is still in the bottle. Whether or not it is accurate is another matter but if the gauge pops up it stops the flow altogether and needs to be reset by pushing it back down. Mine seems to do this frequently maybe because of the jolts on the road. And my hose and regulator on the bus are identical to the one on my BBQ. Anyway, good luck and happy travels.
