Gas cylinder cutting out

[Bannon]

Not sure if this fits in on this forum but maybe somebody here will know.
For our cooker, for the last couple of years we have been using a 47kg propane gas cylinders to supply it with gas.

Our current one which was connected about 2 months ago still seems pretty full going by the weight (they usually last us about 6 months) - has a nasty habit of just shutting down the supply of gas. Why does it do this?

If we leave it for a while it will usually but not always come back on - could it be because of the sort of flat valve (sorry, not a fitter) that sits between the valve on the tank and the supply line?

Never had this happen before and it has got me puzzled and the Mrs peed off!

Thanks guys

A picture of the regulator/cylinder set up would be useful.

I have had problems with an automatic cylinder change over valve failing.....does your system have this?

Thanks for the two quick replies!

We do not have a change over valve on it. We just roll in new cylinder when it is empty and connect it up. That flat item between the cylinder valve and the feed pipe, is it called a diaphragm?

For the life of me I can only think that is what's causing the problem but did not want to just change it on spec.... although I may have to I suppose

have you changed your cooker recently or use more burners etc it could be that the demand is higher than the regulator is rated at in which case it will freeze up if demand is excessive and then will thaw when not drawing gas hence it comes back on

Same cooker from day one Ian, and the last time it went off with just the grill was being used. It has also cut out when the oven has been used on it's own and when one of the hob burners has been used - so it may not be a problem with demand.

Could I have an issue with the cooker itself? It's a Rangemaster Classic 90.

Cheers.

probably need a new regulator.

 

[Bannon]

Is that the bit on the gas cylinder, or on the cooker itself Micky?

hopefully it will be attached to the cylinder. Where is the cylinder located?

Yep if everything is the same then I agree with Mickey its probably the regulator, next time it cuts out go out and see if there is frost or ice on the regulator or associated pipework, this isnt to do with outside temp it is to do with demand from the cylinder

 

[Bannon]

Sounds good guys thanks. Just one more question if I may - I have looked on Amazon (where else these days!) for a regulator and there are two types. A screw on one which I have, and a clip on one. Are they interchangeable and if so, which would you recommend?

Cheers again.

 

[ianmcd]

Not sure what you mean by a clip on one go on to BES Ltd and find the one that you have then browse the net for the same one or order it from them

 

[onecog]

screw in 37mb is what you want.

 

[mickyg]

Where do you keep the cylinder? and how is it connected to the cooker?

 

[Bannon]

Hi Mickyg,

The cylinder is kept against an outside wall, and it goes from a short flexible into a copper pipe. All in all not more than about a metre and a half I suppose. Had a frost last night and I had the regulator valve covered with an old blanket and it seems to be working OK this morning.

Probably worth changing the valve as I read somewhere that they have a limited life of around ten years for some reason, and the valve was in-situ when we bought our cottage about three years ago so.....

Cheers.
