ADJUSTING THE FLAME
FLAME FAILURE
The flame can be adjusted anywhere between the High and Low symbol, do not regulate the flame between High and Off.
Flame Failure is a safety device fitted to some models (listed below). A metal probe behind the burner generates electricity when a flame is present. After 5 seconds the metal probe gets hot enough to hold a valve open and maintain the gas supply. If the flame is blown out then the gas to the burner is cut off.
To operate the Flame Failure you need to hold the burner knob down for 5 seconds after the burner has ignited. Letting go too soon will extinguish the flame.
The Flame Failure models are CG602F/CG602WF/CG602WFC & GC9002 series. If you are unsure if you have a Flame Failure model, you can look at the back of the burners and check there are two probes (spark electrode and flame failure probe), indicating a flame failure model.
