Regulating of the oven minimum
Considering that in the minimum position the ame must have a length of about 4 mm and must remain lit
even with a rapid shift from the maximum position to that of minimum.
To be eected only for the oven burner (as the grill burner only has a xed 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 (g. 55)
• t the knob and let the oven heat for 10 minutes, then take the knob to position 130 allowing the ther-
mostat 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 ame reaches 3-4 mm high.
N.B. For LPG the by-pass screw must be xed thoroughly.
