6 FINAL OPERATIONS
Having carried out the above adjustments, reassemble the appliance
following, backwards, the instructions in paragraph “5.1 Removing the
hob”.
6.1 Regulation of turndown rate for natural gas or town
gas
Replace the components on the burner and slide
the knobs on the gas tap pins. Light the burner
and set it at turndown rate position. Remove the
knob and turn the regulation screw inside or next
to the gas tap pin (depending on the model) until
you get a suitable low flame. Replace the knob
and check burner flame stability: (rapidly turning
the knob from maximum to minimum position,
the flame should not go out).
6.2 Regulation of turndown rate for LPG
To regulate the turndown ratefor LPG, completely tighten (clockwise)
the screw inside or next to the gas tap pin (depending on the model).
The diameters of the by-passes for each burner are given in table “5.2
Nozzle replacement and primary air adjustment”.
After having regulated the device with a gas other than the one tested,
replace the label located on the bottom enclosure with the one that
corresponds to the new gas. The label is inside the bag that contains
the nozzles.
