Advice on fitting BBQ gas point.

[Russ M]

Thanks in advance for any advice.
I’m going to fit two 11kg Gasit tanks into my gas locker.
I thought I’d also take the opportunity to fit a BBQ gas point to the same set up, as Gasit provide a kit.
They tell me that the bbq hose must be fitted after the regulator so that the pries sure is lowered before it goes to the bbq. Makes sense.
I see on some forums people fit a t connector within the manifold area , but this is buried deep in my vehicle and would be hard to get st and work on.
I attach a photo of my gas locker and current regulator. There is quite a long hose after the regulator so is there any issue with fitting a T joint in this rubber hose after the regulator. I could then run a short hose back outside for the connection point to the bbq hose.
This would seem to answer the point that the bbq hose needs to be fitted after the regulator , and rubber hose must be ok after the regulator as it was fitted this way in the Dethleffs factory.
Any advice greatly appreciated.

Can't see a problem with that but where your BBQ hose exits the gas locker make sure you seal the hose hole in the locker wall to prevent gas getting in the van in the event of a gas leak in the locker.

Another option would be a brass compression T to fit below where the rubber hose fits the copper pipe on the back wall with a short length of copper pipe from the T to connect your new BBQ hose to. Just means cutting the copper pipe to insert the T.
That would make the whole thing more secure.

I wouldn't do it as you have described. I would tee into the copper pipework that the rubber hose is connected to at a convenient point. you don't have to tee into it in the gas locker, you might want to fit your external gas connector in a different location, so tee into pipework elsewhere.

in theory you can tee into anything anywhere, including the rubber hose, so long as it is after the regulator, but as you should replace the rubber hose every few years it becomes a pain. the professional method would be to tee into the copper pipework. you don't even have to cut into the original pipework, just add a tee to the end of the existing pipework and re attach the rubber hose. then install a copper pipe up to the gas bbq point. I would also put a gas valve (stop tap) in the pipework feeding the gas bbq point

you might find a local plumber has some 8mm copper you could have - or some local diy stores sell it by the metre - saves you having to buy a large coil !

I see you have the gas bottle top type regulator, most motorhomes that have twin Gas bottles have twin fill regulators that take a feed from both bottles, some have an automatic changeover valve for when one is empty it switches over to the 2nd, some have built in crash detectors to allow you to run fridge & Heating whilst driving, so many choices out there. I would fit the stainless steel feed pipes to supply a twin fed regulator as its very convenient, especially at night if a bottle runs out.#
As for fitting a BBQ point, some people just take a feed off any accessible pipe, after the regulator, many tee into the gas feed to the Fridge Freezer.
I dont condone this method as the BBQ uses a fair flow of gas and could starve the FF in warm weather (thats what the LPG experts said at least) others have teed off and not sustained any starvation problems at all.
I chose rather awkwardly I admit to come off the end of the Truma isolation manifold and fit another separate isolation tap for the BBQ point. This made sense to me so if I had to isolate one, it would not affect the other. I did struggle in getting a 10 to 8mm reducer to exit the manifold. I tried using reducing olives, but it didn't feel right, so I had an engineering company make me a straight 10-8MM brass tube about 65mm long to facilitate this.
Check with a qualified LPG expert and I think they will back me up in saying always come off the manifold with a separate isolator tap for the BBQ.
Hope that helps

6,8and 10mm tubes fit inside each other to solder

If you are fitting refillable gasit bottles ,the regulator in the pic would be redundant . I believe .
@Minxy Girl may have a suitable regulator

Or look at Gasit YouTube videos .
You could get the auto change over from gasit or the simple T junction to feed into the wall mounted regulator ,then a 10mm /8mmT off to bbq point after the regulator .
I went for the simple (cheaper) T included in the kit.

Oops beaten too it

With a twin cylinder system, it's normal practice to install a bulkhead regulator with changeover valve.

You could still use bottle-top regulators with the hoses connected to a T-piece at the top of the steel oulet pipework.

To install the BBQ outlet you really need to insert a T-piece into the vertical steel pipework.

My BBQ outlet is plumbed into the gas feed to the fridge. It's convenient to have it on that side because that's our outside lounging area.

Oops, beaten by others !!!

I was advised to avoid soldering due to constant vibrations when driving can cause solder fracture.
Compression is the way I’d go.

Sorry, somehow I missed the bit about Refillable bottles and as others have said everything but the fixed copper pipe will be replaced with new stuff so connecting to the rubber hose as I said is out.

I'd remove your existing rubber pipe and regulator, put in a T-piece to which you can attach a pipe for your BBQ (assuming your gas locker is on the same side as you'd use the BBQ you can then fit a proper quick release BBQ point in the side, possibly in the bit of skirt below the locker itself to keep it nice and neat and the run short. This way your BBQ would be on the low pressure side as required.

Once the T-piece is installed, assuming there's room above it, you can then fit a bulkhead regulator to which you can attach your refillable gas pipes - you don't need to have a twin inlet reg as you can easily put a T-piece on it to fix both pipes to, this is the set-up I have on mine (its a Cless regulator - I have a Truma one for sale if you're interested).
