They will disappear in time.An orange-coloured flame is normal. This is caused by thepresence of dust in the atmosphere, spilt liquids, etc.If the burner flames are accidentally blown out, switch off theburner operating control knob and do not try to relight it for atleast 1 minute.A few seconds after the burner is switched off, a sound (thud)will be produced. This is not a fault - this means that the safetydevice is no longer operating.Keep the burner as clean as possible. If the ignition sparkersare dirty they will not light properly.
