Gas bayonet fitting and proximity to gas bottles

Gooday,

v Make sure you have a sufficient size copper pipe or whatever you use, I had one fitted to rear of 21 ft caravan they only used 6 mm bore tube, not large enough will not run our WeberQ100 on it, not enough gas.

Cheers,

As suggested CD,The distance would depend on what you are trying to run. At home we use gas for heating and I have a 3m flexible pipe from the wall in the family room. The point is fed in 1/2" copper from the gas bottle.and I run a large Brigadier gas heater. You could always replumb your van gas system to a more appropriate takeoff point.To answer your original question about a regulation distance I really don't think there is one. e.g. Our bottles are up the front and the kitchen is at the rear of the van.Someone who is better versed than I on this subject may beg to differ.

I suggest the gas bayonet should be at least 1.5m from the gas bottles, PLUS the maximum length of a hose assembly, because the appliance is an ignition source and should not be closer than 1.5m from the bottles.

It does not talk about a bayonet Lance, but it does say the gas bottles should not be closer than 1.5m from a source of ignition and what you run from the bayonet is a source of ignition, so it should not be possible (as I read it) for that BBQ (or whatever) to ever be closer than 1.5m from the gas bottles when it is connected and running.

Cheers,

I have a 3m hose that connects from the bayonet to a Ziggy instead of connection to the pol fitting on the gas bottle..

"Should" and "must not be" are two very different things.

That document linked by Peter_n_Margaret is very old and mostly out of date. The Australian Standards (AS) regarding gas have been changed 2 or 3 times since it was written.

New laws are not retrospective.
EG, a van may have had gas work done legally some years ago and a certificate issued, but just because the laws have now changed does NOT make your installation illegal.
If however you have any modification work done then you are required to bring the entire system up to spec with the new laws and to have it re-certified.

Gas laws vary widely from state to state and whilst some states reference the AS for certain portions of their rules, it is often a mix of AS and local rules that make up their laws.
I suggest you approach a licenced Gas Fitter in the state that your van is registered in and have them perform the work and issue a compliance certificate.

Maybe you could post something more current to answer the OP's question if that is the case?

Or maybe you actually don't have a clue?

That document is obsolete, Peter. I have the complete document but I am not at liberty to attach the lot. If you want a section on a particular regulation/standard I can search for same. You are however correct with the requirement to maintain a distance of 1.5 metres between gas cylinder and source of ignition.

Which was the bit relevant to the OPs question. Thank you for that confirmation!

So I can put the bayonet right next to a gas bottle as long as the bbq is at least 1.5m away from the bayonet or bottle

My Hino Rainbow has the gas bottle in a compartment at the rear left-hand corner of the vehicle, and I have a bayonet located one metre in front of the centre of the compartment. I was told prior to the fit-out (in Brisbane, end of 2014) that the bayonet could not be located below a wind-out awning, to comply with new regulations that came into effect from July 2014. I presume this is because annex walls could be erected around the awning and the bayonet would then be within a 'livable area'.

As this work must be done and certified by a licensed gasfitter, I suggest that you follow Hylife's advice.
