Always disconnect the appliance from the electricity main before making any adjustments.
All seals must be replaced by the technician at the end of any adjustments or regulations. Our burners do not
require primary air adjustment.
BURNERS
“Reduced rate” adjustment:
• Switch on the burner and turn the relative knob to the “Reduced rate” position (small flame fig. 1).
• Remove knob “M” (fig. 22 and 22/A) of the tap, which is simply pressed on to its rod. The by-pass
for minimal rate regulation can be: beside the tap (fig. 22) or inside the shaft. In any case, to access to
regulation, it can be done trought the insertion of a small screwdriver ‘’D’’ beside the tap (fig. 22) or
in the hole ‘’C’’ inside the shaft of the tap (fig 22/A). Turn the throttle screw to the right or left until
the burner flame has been adequately regulated to the “Reduced rate” position.
CHAPTER 6. ADJUSTMENTS
FIG. 22/A FIG. 22
The flame should not be too low: the lowest small flame should be continuous and steady. Re-assemble the
several components.
It is understood that only burners operating with G20 gas should be subjected to the above mentioned
adjustments. The screw must be fully locked when the burners operate with G30 or G31 gas (turn clockwise).
TAPS OrRIFICATION Should a tap being blocked, do not force and ask for Technical Assistance.
REPLACING THE INJECTORS
The burners can be adapted to different types of gas by installing injectors suited to the type of gas required.
To do this, first remove the burner tops using a wrench “B”. Now unscrew injector “A” (see fig. 23) and fit a
injector corresponding to the type of gas required.
It is advisable to tighten the injector in place.
After the injectors have been replaced, the burners must be
regulated as explained in paragraphs 12. The technician must
reset any seals on the regulating or pre-regulating devices
and affix the label corresponding to the new gas regulation
on the appliance instead of the already existing one. This
label is supplied in the packet containing the spare injectors.
The envelope with the injectors and the labels can be
included in the kit, or at disposal to the authorized Customer
Care Department.
