Gas

[Andy Norfolk]

Gas not flowing properly. Thought maybe the bottle was going so got a new one. Connected and seemed ok. Went to start cooking later and the issue is back, a few seconds of gas then nothing. Caravan 2 years old.

Went through the manuals, possibly the gas regulator has failed? Looks like an issue for the hab check. Any other ideas?

My first thoughts would be regulator. If tgphe caravan I only 2 years old that shoukd be covered under the new warranty.

Does the gas heating work, or is it just the cooker ?

It has been known for the gas hose to "close up" internally, if your confident enough to disconnect the pigtail hose from the regulator, and open the gas bottle to see if the supply from the bottle is coming through.
DO NOT CHECK WITH A NAKED FLAME.

Thanks. I haven't tried the heating on gas. It's our last day here and I don't have the knowledge or confidence to try what you suggest myself. I know my limitations so I'll get it sorted when the hab check is done but I appreciate your comment.

Are you using Butane or Propane LPG?

With the low temperatures we have seen over the last few days Butane cylinder can stop working becasue they are too cold. When your caravanning and the ambient temperatures are below about 5C you should be using Propane which will continue working in ambient down to about -40C.

 

[Andy Norfolk]

We're using Calor propane. So I guess it's the regulator.

 

[ProfJohnL]

If you are using Propane, then it does tend to suggest a regulator problem, and as Hutch has suggested it should be a warranty job.

In all the years I have worked with LPG, the only flexible hoses that I have seen become clogged and thus unusable were some that were when a caravaner used a piece of laboratory Bunsen burner gas hose for hose BBQ. Or when another component in the system had been disolved and the residue had collected at the lowest point and blocked the pipe work or appliance jets.

LPG will dissolve natural rubbers which is why LPG hoses should be marked in the UL with a BS number and date, class of hose with maximum working pressure, inside diameter of pipe, gas identification and an expiry date.
