1) TRADITIONAL BURNERS

On  the  surface  of  the  hob,  there  is  a  serigraphic
figure  above  each  knob,  indicating  the  burner  to
which  the  knob  refers. After  turning  on  the  gas  at
the  main  or  opening  the  valve  on  the  gas  bottle,
light the burners as indicated below: 

- automatic electric ignition

Press the knob corresponding to the burner to use
and  turn  it  clockwise  to  the  “Maximum”  position
(big flame fig. 1) pressing the knob right down.

- Lighting  burners  fitted  with  a  safety  cut-off

device

For burners fitted with a safety cut-off device,  turn
the  knob  corresponding  to  the  burner  to  use  anti-
clockwise  to  the  “Maximum”  position  (big  flame 
fig.  1)  until  it  stops  and  then  press  the  knob.
Continue  pressing  the  knob  for  about  10  seconds
after the burner has been lit.
Should  the  flames  accidentally  go  out,  turn  the
burner control knob off and wait at least 1 min befor
attempting to light it again. 

How to use the burners

To obtain maximum performance with minimum gas
consumption, remember the following:
- use  suitable  pans  for  each  burner  (see  the  table

below and fig. 2).

- When boiling point is reached, turn the knob to the

“Minimum” position (small flame fig. 1).

- Always use pans with lids.
“DUAL” burner:
separate regulation of the inner and outer rings (in
practical terms, a dual burner controlled by a single
knob),  offering  very  flexible  use  thanks  to  the
possibility to light either the inner flame only or the
whole  burner  (inner  and  outer  flame  at  the  same
time).

LIGHTING AND USING THE “DUAL” BURNER

Stand the pan on the burner before lighting.

Despite  being  controlled  by  a  single  knob,  the

“DUAL” burner can be used in two different ways.

A) - Using the complete burner:

starting from the off position ● You must first press

the knob, simultaneously turning it anti-clockwise,

until  the  indicator  points  to  the  maximum  delivery

position 

obtaining the maximum flow capacity of

both flames.

When the flames are lit, keep the knob pressed for

a few seconds, until the device automatically keeps

the burner lit.
It  is  now  possible  to  regulate  the  intensity  of  the
flame  by  turning  the  knob  anti-clockwise  (from  the
maximum  flow  capacity  position  of  the  inner  and
outer  flames  to  the  maximum  flow  capacity  of  the
inner flame and the minimum of the outer flame.
To  turn  off  the  burner,  turn  the  knob  clockwise,
realigning the indicator with the ● off symbol.

B) - Using the inner flame only:

after  lighting  the  burner  and  regulating  the  inner

flame  to  maximum  flow  capacity  and  the  outer

flame  to  minimum  flow  capacity  as  described

above,  turn  the  knob  anti-clockwise  until  it  clicks

once. The  inner  flame  is  now  at  maximum  flow

capacity while the outer flame is turned off.

Continue turning anti-clockwise to regulate the inner

flame to the minimum flow capacity.

Turning off:

to  turn  off  the  burner,  turn  the  knob  clockwise,

realigning the indicator with the ● off symbol.

Once the “DUAL” burner is operating in either of the

two  modes  described,  it  is  possible  to  swap  from

one  mode  to  the  other  by  simply  pressing  and

turning the knob to the position required:
