Light the oven and let it burn at the maximum temparutere for at
least 30 minutes. Turn the thermostat knob to the minimum and
adjust the by-pass to the minimum so that you achieve a reduced by
stable flame. Perform this operation with the oven door closed.
Use a flat-head screwdriver on the by-pass screw. It is sufficient to
loosen the screw several turns to adjust the minimum when
changing from liquid gas to natural gas.
IMPORTANT
: once adjusted the burner, check that the minimum
flame is maintained, test-ing if by repeatedly opening and closing
the oven door. If the flame goes out, adapt the by-pass adjusment.
Complete the operations (replacing the injector, adjusting the air
and minimum), turn off the oven and apply the new data plate
(which shows the type of gas being used) replacing the previous one
and apply seals using sealing wax or similar.
