7. USING THE HOB
Make sure that the flame-baffle crowns, the caps and the grid have been
assembled correctly. Grid A (supplied) should be used for "woks"
(Chinese pots).
Adapter B (supplied) is to be used for small vessels.
7.1 Ignition of the burners with safety device
For each knob the corresponding burner is indicated. 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.
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 cock is open.
7.2 Practical advice for using the burners
For better burner performance and minimum gas
consumption, flat bottomed, even recipients must be
used, with covers and proportional in size to the
burners (see paragraph “7.3 Diameter of containers”).
To avoid overcooking or damage to the surface top
while cooking, all recipients or griddles must be
positioned within the cooking hob perimeter and must
be a minimum distance of 3-4 cm from the knobs.
