AUTHORISED PERSONNEL ONLY.
Before carrying any servicing operation disconnect the appliance from gas and electric supply and extra
appliance from final installation place in order to have access to the appliance for proper servicing
intervention.
STEP 1: PRESSURE REGULATOR.
For NG or ULPG installation ref. to fig. 7 and chapter ‘Appliance gas connection’ 7
STEP 2: SURFACE BURNERS
For surface burners conversion ref to table 1 chapter ‘Adaption to various types
of gas’ and chapter ‘Conversion to different types of gas’
STEP 3: VISUAL CHECKS
The following visual check must be performed to ensure that the conversion has
been carried out properly and without damage to other components of the range.
Verify that the flame of the oven burner be completely blue and with regular aspect
as shown below.
CONNECTION OF THERMOCOUPLE TO THERMOSTAT
The thermocouple for oven burner is connected to the magnet. Tight gently the connection.
The tip of the spark plug or thermocouple must fully overlap at least the first gas emission hole of the burner.
After performing all these visual checks, reinstall the bottom panel of the oven compartment and proceed
to setting the minimum for each burner.
STEP 4: MINIMUM FLAME ADJUSTMENT
WARNING!
These adjustments should be made only for use of the appliance with Natural gas.
For use with ULPG, the bypass screw must be fully turned in a clockwise direction.
Surface burners
Light one burner at a time and set the knob to the MINIMUM position (small
flame). Remove the knob.
The range is equipped with a safety valve. Using a small-size slotted screwdriver,
locate the choke valve on the valve body and turn the choke screw to the right or
left until the burner flame is adjusted to desired minimum.
Make sure that the flame does not go out when switching quickly from the
MAXIMUM to the MINIMUM position.
Greasing the valves
If it becomes difficult to operate the valve, it should be greased immediately by
following the instructions listed below:
1) Disassemble the valve body by loosening the two screws located on
the body of valve.
2) Extract and clean the seal cone and its housing with a cloth.
3) Lightly grease the cone with special grease.
4) Insert the cone, moving it several times, remove it again, remove the
excess grease and make sure that the gas passage ways are
unobstructed.
5) Replace all the pieces by reversing the order in which they were
disassembled and check that the valve operates correctly.
Room Ventilation
To ensure that the appliance operates correctly, the room where it is installed must
be continuously ventilated. The room volume should not be less than 25m3 and the
quantity of air should be based on the regular combustion of gas and on the
ventilation of the room. Natural air will flow through permanent openings in the
