REPLACEMENT OF THE TOP
INJECTORS
(Fig. 8.5)
– Loose the screw "M" of each injector
and fully raise the adjusting air tube
"A".
– By a polygonal 7 spanner, remove the
injector "J" from their housing and
replace it by the proper one according
to the kind of gas (see injectors table).
ADJUSTMENT OF PRIMARY AIR OF
TOP BURNERS
By operating on the screw "M", reset the
air adjuster "A" according to the instruc-
tions indicated on the table for the
choice of the injectors, where the dis-
tance between injector and air adjuster
is recommended (in mm).
Before lowering the cooktop, set the
burners on their sites and light them in
order to check whether the flames are
correct, as per the specifications given
in the next page. In case of uncorrect
flame, lift or lower the air adjuster.
ADJUSTMENT OF THE MINIMUN OF
THE TOP BURNERS
Considering that in the minimum posi-
tion the flame must have a length of
about 4 mm and must remain lit even
with a brusque passage from the maxi-
mum position to that of minimum.
The flame adjustment is done in the fol-
lowing way:
– Turn on the burner
– Turn the tap to the MINIMUM position
– Take off the knob
– With a small flat screwdriver turn the
screw inside the tap rod to the correct
regulation (fig. 8.6).
Normally for G30/G31 gas, tighten up
the regulation screw.
