ADJUSTING THE THERMOSTAT MINIMUM SETTING
This operation is performed with the oven in the unit and after the electrical and gas connections
have been made by qualified personnel. The operation is necessary when switching from
one type of gas to another (from natural gas G20 to liquid gas G30) in order to guarantee a
minimum temperature of around 150°C.
• open the oven door (the burner will ignite only with the door open);
• remove the bedplate (base) of the oven;
• operate the oven at maximum temperature for at least 20÷30 minutes;
• once the oven is on, close the door;
• reset the thermostat knob to 150°C;
• remove the knob A (fig. 9);
• insert a screwdriver into hole B parallel with the thermostat shank and adjust the by-pass until you obtain a
reduced but stable flame. This operation must be performed with the oven door closed.
• Use a flat blade screwdriver (fig. 9) to adjust the by-pass screw. Simply unscrew the by-pass to
adjust the minimum setting when switching from liquid gas to methane.
• For operation with G30/G31 (LPG) the by-pass adjustment screw must be fully tightened.
IMPORTANT:
after adjusting the burner, check that the flame is maintained at minimum setting as follows:
1. turn the knob from min. to max. 2-3 times;
2. open and close the oven door continuously (neither too fast or too slowly);
3. if the flame goes out, adjust the by-pass setting (slightly increase the minimum setting).
• Once you have finished (replacement of injector, adjustment of air and minimum setting), switch the oven off
and affix the new rating plate (indicating the gas used).
