I have a calorgas 2 hob , grill and oven on board Cuchilo and over the last few months the flame on one of the hob burners has been going out shortly after lighting it . Once lit again it stays alight . Any ideas why this is happening ?

We took our's to 'Brisco williams' on Cowbridge rd, Cardiff and they did full service for £40 (new burners,valves etc) Maybe worth a try.Edited- sorry thought you/i was on the Cardiff forum!!

Flame failure thermocouple had it. Usually you have to keep the knob pushed in for a few seconds to allow it to heat up, so that it hold the valve open to allow gas to burn. If it wont keep the flame alight then thats your problem.
Had same problem ona ENO cooker which is 29 years old, and original on my E32. Was pleasantly surprised to find a UK spares supplier who supplied a replacement thermocouple for about a fiver and next day delivery.
Suggest you Google your cooker make and source spares. If not confident get a Corgi guy to fit it... at least he will be in and out in 5 minutes once you have the part to hand

Just to prove whether or not it is the thermocouple you could swap them over. If the problem moves to the other burner then the thermocouple is duff.

ps Please don't blame me if, after trying this, neither of them works!

We have a similar effect on our cooker. It does only happen though the first time after turning the cylinder on. You light either burner and after say 8 secs it goes out, but after another few secs it will light and stay on. I have always assumed that there must be a tiny leak somewhere which allows the gas to diffuse out during the week before we come back to the boat. Any body else have this issue ?

Yes. we have a plastimo atlantic in ours and when we turn on the gas and light either burner ( after a week not been on board) the flame tries to extinguish or blow itself out, and its been like that with two different regulators fitted, so am not convinced it is a regulator problem.
We are using Camping Gaz bottles/regulator.
The left hob is usually worse than the right one, there are no flame failure devices fitted to the hobs, only oven.
By turning down the gas at knob helps to reduce or eliminate the effect.
Suspect it could be down to the centre top part of burner is a little loose, but the retaining screw is seized in and will break off if I try to loosen/tighten it.

My cookers have never had flame failure devices fitted to the hob or grill, only the oven. You only have a flame failure device if you need to hold a red knob in until the flame is lit for a few seconds.

I suspect you have some gas in the pipe that lights but burns through before the fresh gas get through from the cylinder. Try putting the gas on for a second or two before lighting it.

I think you're right there . I have a shut off valve after the gas bottle valve aswell as a test point just before the oven .
I'll try turning off the gas and let the flame burn out before i shut every thing off . Thinking about it this is the best way to leave the set up anyway .......As long as i can turn off the hob as soon as the flame goes out !

If the gas cylinder has been tipped or moved whilst the regulator is fitted, quite easy on a boat, it is possible for liquid gas to enter the regulator. When you turn on the gas the flame is fierce and blows its self out. Safety wise the gas in pipes should be burnt off, and a flame or igniter lit ready when the gas is turned on.
