Gas hob question- Yellow flame + rushing sound ??

Myser

Buy a CO alarm immediately before you even consider switching that hob on again.

:rotfl::rotfl:Never ceases to amaze me how inexpert some experts are and how panicky people get with CO in circumstances like this :rotfl::rotfl:

OK lets get some sensible perspective here, IT A COOKER WITH A PROBLEM ON ONE HOB BURNER, JUST DONT USE THAT BURNER

As for the problem, the hint to the experts should be yellow flame associated with a whooshing noise and black residue THE BURNER IS LIGHTING BACK ON THE INJECTOR due to incorrect air/gas ratio, probably caused by a blockage in the SECONDARY AIR SUPPLY due to blocked holes in the burner itself, remove the burner cap, it should just lift off, and wash it in warm soapy water and dry the black residue is soot created because the flame is burning inside the burner tube at the PRIMARY AIR SOURCE, THE INJECTOR ON THE BURNER RAIL;) and that is also blocking the burner ring TOO:)

if it is producing a yellow flame you should turn it off and not use it again until checked by a suitably qualified gas safe engineer.

if you have any concerns for safety call 0800 111 999 and the gas emergency service will come out and make safe.

Calor Gas burners (if set up right) should produce a predominantly blue flame that is controllable and clean without yellow tips and/or sooty deposits on pans/ovenwalls/kettles.

The usual cause of a yellow tipped blue flame and sooty deposits on Calor Gas butane/propane is a lack of air and overly rich mixture;it should be all predominantly blue without yellow tips or soot if set up correctly but it can also happen if a natural gas cooker is used straight on Calor Gas butane/propane without the proper conversion to LPG using the appropriate jets/injectors/nipples etc for that gas.

Look at this video for an explanation:

The video shows a correct looking flame which should be present on LPG if things are set up right.

This is the sane answer.

Running a gas flame yellow for no more than a minute in a well ventilated room is not going to kill you. 20 minutes with no ventilation is a very different matter.

Wash the burner as advised by Mr Ted, make sure it is dry. Then try it. If the flame is blue, then the job is a good one. Otherwise get a gas fitter in.

:DThank you VH, and people wonder why I get sarky when I see some of the advise;)

If a few more actually had the years of experience that gave that answer, they might not be so quick in calling people ol farts, as working on town gas, and the early days of NG, that particular problem was quite common as there wasnt the air adjustment available on cooker hob burners on converted appliances, and light back was common:)

AND I do so like smileys :rotfl::rotfl::rotfl:the poor inoffensive lil fella's do upset so many stiff collars
