Gas barbecue connection problem

[Garry McG]

I have fitted a bullfinch gas outlet point to the outside of my van and connected it to my lpg supply all smooth and easy.
My problem is that the barbecue I have bought a Kuhn Rikon VK9000 the regulator it comes with is for gas canisters. Is there anyway of adapting it so that I can hook it up directly to my bullfinch fed hose. This is the regulator. Also surely the connection between the regulator and the barbecue need to be tight. There is some play on the connection even when fully tightened. Any advice appreciated.

If you connected the Bullfinch correctly to LP side of your vans gas supply...ie after the reducer you won't need separate regulator for your bbq.
Connects straight to Bullfinch via appropriate gas hose

Only problem with that is I will then have no control over the gas supply as the flow control is on the regulator.

as said above , assuming you nhave connected your bbq point on the inside of your van regulator, just cut the gas cannister reg off and fit the bulfinch adaptoir plug in...

then you either need to replace it with a gas tap or get a new Barbie

As above. Provided you have connected "after" the van regulator you can bin the blue regulator and attach a hose to the Bullfinch connection one end and the barbecue the other end. You could always use a quick release coupling on the barbecue to attach the hose to which sometimes makes it easier to stow the hose depending how long it is.

As the flame height control is part of the existing gas canister regulator and possibly the wrong sized jet it looks like a new BBQ is in order.

Can you measure the threaded portion on the end of the regulator, if it's a common size (e.g. 1/4" BSP) you could just buy a small handwheel valve and a hose tail and do away with the regulator.
I made the opposite fitting for refilling the little 200 gramme gas canisters for my Jetboil and fitted it and a hose tail to a 1/4" BSP valve.

 

[Garry McG]

thank you for that will try and see if that works.

Problem solved with a bit of jiggery pokery. Had to solder the injector fitting to the coupling nut to stop it wobbling about then lots of jubilee clips. More soldering of 8mm copper onto two 15 to 8mm reduces one full lever gas safe valve and a quick release fitting later job done.

No expert mate but it looks as if the olive in the bottom right corner isn't in right.

I thought that at first as well but then thought it was PTFE tape?

Yeah blown it up now and it looks as if you are right

You could have picked your words more carefully! "Blown it up" and gas fitting in the same thread!!!!

Although I must admit I have done it before now but I thought you shouldn't use PTFE on gas compression fittings.

It is just ptfe tape. All joints tested and sound. Going to be used outside anyway so all good.

PTFE should not be used on ANY compression fittings.
It is to seal screw in thread joints .. thus the reason it is called "thread tape"

I noticed that, it shouldn't have PTFE tape on an olive and it put it on a tread its needs to be the gas one not standard PTFE tape.

Well there you go , right for once, when you think we had a thread yesterday someone couldn't fit a bottle top regulater then look at this one.
Not suggesting anything either way other than the difference in what posters think they can or can't do

Point taken Poppycamper. However if the olive connection is not tight then tape on the thread is wasted as gas will still escape out of the compression joint. Gas PTFE is acceptable being less prone to becoming porous being thicker than the more stretched plumbers ptfe tape. All joints have been tested under pressure and found to be sound so I am happy to use it even if it has been slightly over-engineered.

So why bother putting thread tape on the threads of a compression olive joint... As I stated it is designed for a screw in joint..... that is a joint that the only sealing surface is the male and female thread when screwed together.

You can Easily get 8mm gas valves , rather than adapting a 15mm one , you shouldn’t really Use ptef on a compression joint , seems to be a DIY thing , many times I’ve seen Tape on the nut threads of a compression fitting , this only makes the threads tighter making it harder to compress the olive therefore making the joint less likely to seal

I’m just waiting for a loud bang and lots of tiny bits of MoHo and other stuff raining down from the heavens. Surely you can buy a connection for the bullfinch end and a connection for the Barbie and not have to resort to jubilee clips and gas taps with dodgily tightened compression fittings? I really don’t want to sound critical but I’d definitely be treating this as the mark 1 version and seek improvements in all aspects of it’s design and manufacture, for your own safety if not for others.......
Now from a constructive point of view perhaps you could post pics of the bullfinch end and the barbie end and see if we can come up with a less complex solution?

Cheers,


Russ

The OPs original issue was that the controlling valve for his bbq was part of the regulator for said bbq.. so if he bypassed regulator he had no control of bbq

Motorhome Enginerr is coming at 9:30 today to pipe up my bullfinch gas point. I put it on the metal skirt of my Hymer didn’t want body cut
