External gas fitting

brickies · Guru

I would think if he is a gas fitter he would know the rules , If it was me i would always put safety first .

ibbo · Guru

The reason for a shut off valve would be in case the fitting was damaged and leaked.The shut off valve would then stop any further gas flow from thegas source.This is only my thought on the matter but I am sure that the gas fitter is correct.Cheers.Ibbo.

I dont think you are being conned at all, the main priority is safety "yours"

I would start the process with a shut off valve from bottle (isolation) leading to a copper line (not flexi) then to a bayonet fitting behind a little door, all enclosed and up out of the way

when traversing stony or gravelly roads you would be surprised at where the rocks get to and how much damage they can do

take his advice and if anything ask him to double up the insulating properties of the lines involved, listen to the experts or you will regret it

I do a lot of work of this type here but I always get advice first!

better to spend an extra hundred now rather than fix it later

I beleive the safty valve is a bit like a regulater in that it only allows enough gas through for tho job ,as far as that bit goes .

In the case of a ;;eg. hose or baynett fitting failure , wich in turn will release a large volume of gas ,the valve will shut down the system .

Like what has been said ,go with expert advise .

Happy BBQs

Hi Neil When I removed all the gas lines from my Millard van it had taps on each line to isolate each unit. One for the frige & one for the stove. Hes probably fitting one to the line so it can be isolated. I have that type of fitting in my house where the gas heater plugs in & it only has a rubber seal in the bayonet fitting, which could posibly leak. I would be happyer with a shutof valve. Cheers Daryl

Like the man said....................Safety first.............especially with gas!!!

One small stop valve ain't gonna break the bank but the lack of it, could blow it up!!

Electricity
and anybody elses wife.
youre in for a lot of hurt if anything goes wrong. take care mate & merry Xmas.......

Delta18 · Guru

Heh heh, thanks Biggles, are the 'don't do's in order of importance?

Ok I am convinced, a shut-off valve we will get, the last thing I want is to be worrying while Baby is cooking the steaks, we don't put her in the corner.

Sorry about that, I have watched too many replays of Dirty Dancing, I think I know it word for word now. lol

Cheers

Hi oh knowledgeable ones

I want to fit a gas bayonet outside the van so-as to remove the need for a separate gas bottle for my webber babyQ.

I have bought a new 1.5m gas hose with bayonet fitting, only $24 and the under van fitting.

I have spoken to a gas fitter, as this job needs to be done by one, and he says that a shut-off valve legally has to be fitted on the line. What th'.

Has anyone heard of this?

I guess I can see that IF this valve is turned off after use, and IF the fitting was damaged by a rock whilst travelling, and IF the gas were still turned on at the bottle, which it NEVER is (is it!) then it may have a use.

Am I being conned?

Cheers

Neil

Hi Neil where did you purchase the 1.5m gas hose with bayonet fitting, I have been looking for some time for this item

Cheers

Norm

I'll try to explain this as simply as I can..

Were an installation has more than one appliance attached each appliance must be fitted with an isolation valve..

That means if there is only one appliance there is no need for a separate isolation valve as the gas can be turned off at the supply point (in the case of RV's thats the cylinder)

Supposing you already have an isolation valve on your Stove/HWS/Fridge then there is NO need to fit a Valve on the Bayonet point as it in itself is a self closing valve..

The reason for having a valve on each appliance is so that appliance can be removed from the installation without affecting the operation of the rest of the installation.

To service the appliance running off the Bayonet point the appliance can simple be disconnected at the Bayonet point and serviced or packed away in your case..

Bayonet points are used more and more these day as an isolation valve for Room heaters, stoves, BBQ's etc..

Hope this helps and you can tell your gas fitter to ring me if he still wants to fit a separate valve.. smile

You should be able to get them at Tradelink or from your local plumbers supplies

My Bailey had a bayonet already built in , but to get it to australian " standards" as it was classed as being inside the van even though it was only accessible from the outside in its own cavity behind the usual door/ flap that caravans have connections etc behind , so we had to abandon that and install another under the van ......

It would have depended IF the box was sealed and also IF the bayonet point had an AGA approval on it.. there are many bayonets that dont meet the Aust Standard that are safe to use in other countries that use a different mix of gas (more Butane than Propane).. smile

I must try the bayonet fitting on my van when I get home tonight. I must familiarise myself with everything for the maiden voyage next week.

Plendo · Guru

Neil,

I suspect your van should already have a gas bayonet under the front left corner of the van. I know you bought your van about the same time we did, and it was standard on all the larger Retreats at the time.

If it is similar to mine it will be just in front of the front left jack leg, it will point down, and have a black plug installed in it.

BBQs Galore have those hoses normn .

Yes, definitely fit an isolating valve (gas ****). Our van certainly has one fitted and I'm pretty sure it is needed under the gas code as you have other appliances fitted in the van (each would also have an isolating gas ****).

So no, you're not being conned.

DO NOT run a gas hose to supply a bayonet fitting. Have it piped in copper AND protect from rocks with plastic tube covering or something similar. Yes I am a licenced gas fitter!
