To be effected only for the oven burner (as the grill burner has an only fixed input)
operating on the thermostat as follows:
– light the oven taking the knob to Max. position.
– remove the knob and by a thin screwdriver (3 mm section - 100 mm long) unscrew
of about a half turn the screw by-pass, passing through the front panel hole (fig. 46)
– fit the knob and let the oven heat for 10 minutes, then take the knob to position
150 allowing the thermostat to work under by-pass.
– after further removal of the knob, stop slowly the screw by-pass G (being careful not
to turn the knob rod) until the flame reaches 3-4 mm high.
N.B. For LPG the by-pass screw must be fixed thoroughly.
