7. USING THE HOB
Before turning on the burners, make sure that the burner rings, caps and
grids have been fitted correctly.
In the ultrarapid burner, notch A must be aligned with pin B.
Grid C provided is intended for use with woks (Chinese pans).
Adapter D comes only with open grids models and is intended for use
with small sized vessels.
7.1 Ignition of the burners
The device is fit with electronic ignition. Simply press and simultaneously
turn the knob counter-clockwise on the low point flame symbol, until the
burner is ignited. Concerning models with valves, push the knob for
approximately 2 seconds in order to keep the flame burning and to
activate the safety device. The burner might go off when the knob is
released. In this case repeat the aforesaid operation keeping the knob
pressed for more than 2 seconds.
Double-
crown burners comprise an auxiliary and a rapid burner,
controlled by two different knobs which permit to use both burners at the
same time or to select one or the other as required.
Should the burners go off accidentally in the models with valves, a safety
device will trip after approximately 20 seconds to block the gas outlet
even if the tap is open.
