4 FINAL PROCEDURES
Having replaced the injectors, remount the flame spreaders and caps of the burners and the racks.
Once you have adjusted the appliance for use with a different gas from the factory-set one, replace
the gas setting label on the appliance with the one corresponding to the new gas. The label is placed
inside the case containing the injectors.
4.1 Adjusting the minimum setting of hob burners for natural gas
Light the burner and adjust it to the minimum setting . Remove the knob
from the gas tap and turn the adjustment screw next to the tap rod until a
constant minimum flame is obtained. Remount the knob and check the
stability of the burner flame (if the knob is turned rapidly from the
maximum setting to the minimum setting, the flame must not go out).
Repeat this procedure for all the gas taps.
In thermocouple models, hold the knob at the minimum setting for around 1 minute to keep the flame
lit and to activate the safety device.
4.2 Adjusting the minimum setting of hob burners for butane/propane gas
To adjust the minimum setting with butane/propane gas, the screw next to the gas tap rod must be
fully tightened clockwise.
The diameters of the by-passes for each burner are set out in paragraph “3.2/3.3 Tables of burner
and injector characteristics”. Once the adjustment has been completed, replace the by-pass
protective catch using nail varnish or another adhesive.
4.3 Adjusting the minimum oven burner setting
The oven thermostat is equipped with a device for adjusting the minimum setting which is visible if
you take out the thermostat knob.
If you change the supply gas type, you need to adjust the device as follows:
• Light the oven burner and keep it at the maximum setting for 10/15 minutes with the oven door
closed. At the end of this period, turn the knob to the minimum temperature setting, take out the
knob and insert a screwdriver to carry out the adjustment.
• Where butane/propane gas is being used, the screw of the device must be turned in a clockwise
direction as far as it will go. The diameter of the device is indicated in paragraph “3.2/3.3 Tables
of burner and injector characteristics”.
• Where natural gas is being used, set the device in such a way that when the thermostat knob is
turned from the minimum to the maximum setting, the flame is stable and consistent. Once the
adjustment has been completed, replace the by-pass protective catch using nail varnish or an
equivalent adhesive. When closing the oven door, ensure that the burner remains lit at the
minimum setting.
