Low gas pressure after bottle change?

My 907 camping gas bottle finally ran out after at least 8 years. Did an exchange for a full 907 bottle and connected up.
Turning the gas on it took a little while to come through to the burners, then only gave me a small blue flame and failed to light the whole ring.
I assumed it was a fault with the bottle so changed it for another one. Same issue.

Before I get an expert involved (no offence), am I missing something? The bottle design is slightly different to the old one but fitted my regulator as before.

Worked perfectly before, the bottle ran out while I was boiling the kettle.

It could be due to cold temperatures,
Or an over filled bottle . If over filled vent off a little gas and try again.

Thanks for the swift reply Momac, it was at least 10 degrees today to temp shouldn’t be an issue.
How would you vent, take the hose off the regulator?

Take the cylinder off the boat to an outdoor area such that gas will be no hazard. Press down momentarily on the ball valve with a preferably blunt object taking care not to damage the seal or the valve.
 
I’ve had this with propane bottles. Not sure if camping gas is the same.
The fault may be an overpressure valve that has shut off. They are meant to open when the over pressure is not present, but if they are old sometimes do not.
Changing the regulator has resolved the issue for me. Try changing the regulator and then turn on the cylinder just a small amount so as to limit the flow.
 
Changing the regulator can do no harm . If changing the regulator then change the orange gas hose at the same time.
Presumably the regulator worked fine with the previous gas bottle so that's why I suspect over filled gas bottles .
The fault in this case sounds like a fault I had last year and was solved by the method I described earlier.

fair do's ...

The other thing of course is that if liquid has got to the regulator - it needs time to clear and operate freely again.

If OP is about 10 C temp - then its not temp related as even Butane will be ok at that. Many people know that most GAS supplied is now a blend of Butane and Propane to allow the bottles to work in low temps .. even sub-zero. But if real below zero temps - then it needs Propane.

Do be careful with this. My uncle had a CG bottle that needed this treatment every time he connected it. After about the 5th time, the ball shot out of the valve and the bottle emptied itself. No harm done, but if someone had walked by with a cigarette at the wrong moment... :eek:
 
Camping Gaz has a history of overfilled 907s. Common issue, vent off a bit of gas. It appears like a regulator issue, but is overfilled.
 
Had exactly the same about 6-8 weeks ago when I tried to boil kettle. Changed Camping Gaz 907 bottle, no different. Changed to new regulator. No different. I then asked local gas specialist to come, fix and certify system, but he hasn't come yet. I will chase him as I do want the certification.

Now I have warmer days I maybe should try again. Cold affecting butane is nothing I've had before in 20 years of using gas - before that my own boat cookers were all paraffin.

Must admit the one I had last year was the only the second ever campingaz cylinder to have any problem. The previous occasion was more than a dozen years ago.
The high price they charge for a refill and considering over filling is potentially hazardous they should get it right .

Ahhh!! Was the 8 year old bottle empty, or was it the regulator?....

If the regulator and hose are as old as the bottle they probably should be changed. Is it every 5years they should be changed? ??
 
Thank you guys, this is really useful.
I’ll try the suggested fixes next week and report back.

Hoses should be changed after 5 years from the date of manufacture

Regulators after 10 years.

Are regulators also meant to be marine spec (stainless steel?).

GasBOAT 4005 Marine Gas Regulator for Campingaz (16mm x 1.5) Part No: 307703​


ASAP supplies offer them

I have had standard regulators cease working after a very short time, and others lasted ages.
 
OOP'S ..... my regulators and hoses are well over 15yrs .. 20yrs for one boat ... still good - because I don't fuss with them.

Regulators are standard over counter - nothing marine about them.

The Inland Waterways requirements quite often get quoted by people - but in fact for seagoing boats - there are no rules on this in UK.

It may come up if a surveyor reports it and Insurance Co. then want it replaced ...
 
Funny things the regulators,switched my 907 to a much bigger bottle and the same regulator just would not work, changed bottle same thing, bought another regulator same thing.Got hold of a older 2nd hand 1....Perfect.

the same bottle is nearly empty now , so i am hoping i will not have the same absulute head scratcher!
 
There are marine regulators, certainly for propane. I think the over pressure valve is part of it and they are designed to comply with IS0 10239.

On the Hamilton gas products website it says:

IN 2001 THE RULES FOR GAS REGULATORS CHANGED - ANY VESSEL WITH A GAS SYSTEM NOT FITTED WITH EN 12864 ANNEX M APPROVED GAS REGULATOR IS NOT COMPLIANT WITH ISO 10239 AND THEREFORE THE VESSELS INSURANCE COULD BE INVALID!

Not sure how factual this is!
