GAS CONNECTION
Make sure that the appliance is adjusted for the gas type available (see the
label under the appliance). Follow the instructions indicated in the chapter “gas
transformations and adjustments” for the possible adaptation to different gases.
The appliance must be connected to the gas system by means of stiff metal pipes
or flexible steel pipes having continuous walls, in compliance with the regulations in
force. Some models are equipped with both cylindrical A and conical B connectors
for gas supply (fig. 7 & 8).
Please select the type which is correct for the supply concerned. The connection
must not stress the gas ramp. Once the installation is over, check the connection
seal with a soapy solution.
ELECTRIC CONNECTION
The connection to the electric grid must be carried out by qualified personnel and
in conformity with the regulations in force. The voltage of the electric system must
correspond to the value indicated in the label under the appliance. Make sure that
the electric system is provided with an effective ground connection in compliance
with the regulations and provisions of the law.
GROUNDING IS COMPULSORY
This device must be at a suitable opening distance from the contacts in order to
allow the entire disconnection in case of over voltage category III, in accordance
with installation rules.
GAS ADJUSTMENTS
- Take precautions on the operations and adjustments to be carried out when
converting from one gas to another.
- All work must be carried out by a qualified technician
- Before you begin, turn off the gas and electricity supply to the appliance.
CHANGE THE INJECTOR OF THE BURNERS
- Remove the pan support, Burner Lid and Flame Spreader.
- Unscrew the injector using a 7mm box spanner and replace it
with the stipulated injector for new gas supply.
- Carefully reassemble all the components.
- After injectors are replaced, it is advisable to strongly tighten
the injector in place.
ADJUSTMENT OF MINIMUM
LEVEL OF THE FLAME
- Turn the taps down to minimum.
- Remove the knob from the tap and place a small bladed
screwdriver in the centre of the tap shaft.
- The correct adjustment is obtained when the flame has a
length of about 3 - 4 mm.
- For butane propane gas, the adjusting screw must be tightly
screwed in.
- Refit the control knob.
- Make sure that the flame does not go out by quickly turning
from maximum flow to minimum flow. If it does then remove
the control knob and make further adjustments to the gas
flow, testing it again once the adjustment has been made.
- Repeat this process for each one of the gas taps.
