Operation
Hob burner control knobs
The symbols on the knobs mean:
z
= no gas supply
= maximum gas supply
= minimum gas supply
For easier lighting, proceed before
putting a pan on the pan support
.
Lighting the burners
Push the relevant knob down and
turn it anti-clockwise until it reaches
the "maximum" position.
Only for mod. ZGF 646 CT / ZGF
646 IT / ZGF 648 IR / ZGF 643 ITXC
After lighting the flame, keep the
knob pushed down for about 5
seconds. This will allow the
"thermocouple" (see figure - lett. D) to be
heated and the safety device to be
switched off, otherwise the gas supply
would be interrupted.
Then, check the flame is regular and
adjust it as required.
If you cannot light the flame even after
several attempts, check the "cap" and
“crown” (see figure - lett. A, B) are in the
correct position.
When switching on the mains, after
installation or a power cut, it is quite
normal for the spark generator to be
activated automatically.
In the absence of electricity, igni-
tion can occur without the
electrical device; in this case
approach the burner with a flame,
push the relevant knob down and
turn it anti-clockwise until it
reaches the "maximum" position.
