Gas hob question- Yellow flame + rushing sound ??

TC1

Hi,

We have a Rangemaster dual fuel cooker fuelled by LPG from 47kg cylinder.
One of the gas rings when lit sometimes has yellow flames together with a rushing sort of sound. Lots of black residue on ring and smell of fumes. I guess it's something to do with the jet. I've tried cleaning it with no real difference.

Are the jets easy enough to remove and replace or is this a job for an expert ??

It sounds like you are not getting the correct mixture of gas to air. Is the air intake blocked at all , perhaps by spillage ? The air intake should be an adjustable sleeve close behind the jet.

Failing that, you could email Rangemaster through their website and ask the question. I did that with a query about cleaning the filters on my Rangemaster extractor. Their answer was to put them in the dishwasher, and they sent me the manual as a PDF file to support that.
That made me feel justified in spending a bit more on their product!

next time you go to asda you can buy canned air in the photo/dvd department its £ 3 for a big can,with fuse wire and,
coupled with kitchen spray it might do the trick, however by your post it sounds like,
the particular tap on the hob is partly blocked on the main gas rail
some of the molykote grease is stuck/spread and its whistling this is a common problem
the gas tap on the particular burner, when you turn it, is shaped like a brass wedged bullet with holes that get gradually bigger, within a outer casing,
they either get stuck with non use, get blocked and noisy by grease spreading ,or leak gas,
yours is partly blocked and noisy like a " flute " and yellow :mad:
its producing carbon monoxide into your kitchen
do not use it till you get it sorted........

I'm afraid you'll need to get a GSR in to check it out properly. Changing jets is not something you can do yourself plus, it might be some other fault.
I know its not really what you wanted to hear but imagine the concequences of getting it wrong.

Yellow flames on a gas appliance is one of the carbon monoxide warning signs. Turn the appliance off, open a window and don't use it again until its been checked out properly.

You either have too much gas or not enough air as the mixture is too rich. Don't use it until checked and cleaned by a professional.

Very often the cause of yellow tipped flames with soot on Calor Gas butane/propane cylinders is a too rich gas mixture(too much gas/not enough air). It can also happen if the unit is used straight on Calor Gas butane/propane without proper conversion from natural gas to LPG. Get it seen to and/or adjusted by a Gas Safe registered engineer qualified to work on LPG servicing/installation.:j

Candles emit small soot particles, these glow and create the yellow flame. It's normal and safe. Gas however should never burn with a yellow flame, this only happens when not enough air is being combined with the gas, and when that happens carbon monoxide production is a certainty. There just isn't enough oxygen to make CO2 from all the carbon, so it makes some CO. Gas flames should be predominantly clear blue. If they're yellow, something is wrong with your appliance. So, in perspective, the issue is not that all yellow flames are bad, it's that yellow gas flames are bad.

I'll sit in a room with a candle, you sit in a room with that cooker and we'll see who snuffs it first.

You're wrong.
