Foster KS 60 user manual Setting of the minimum

Setting of the minimum

The oven thermostat is equipped with a by-pass for the minimum; when changing the type of gas it is also necessary to adjust the setting in the following manner:

Remove the thermostat knob;

If the front panel is in glass, remove it by unscrewing the two locking ring nuts located under the other two knobs (fig. 1);

If the control panel is in metal, the adjustment can be made through the opening located on the left side of the thermostat knob housing (fig. 2);

Turn on the oven and let it operate at maximum with the door closed for at least 30 minutes;

Move the oven thermostat knob to the minimum and set the by-pass to the minimum so as to obtain a reduced but stabilized flame. Perform this operation with the oven door closed;

Use a screwdriver to operate on the notch of the by-pass screw. A few turns of the by-pass screw is sufficient to adjust the minimum when passing from liquid gas to methane gas;

1.2.

IMPORTANT: after having adjusted the burner, open and close the oven door to check that the flame remains lit at the minimum. If the flame goes out, adjust the by-pass setting.

For operation with G30/G31, the adjustment screw of the by-pass must be screwed in completely.

When these operations are finished (injector replacement, air adjustment and minimum setting), turn off the oven and replace the data plate with the new data plate indicating the operating gas.
