fan when the temperature rises over 37°C.

PIZ3G FAULT DESCRIPTION

When there is a fault, a buzzer rings and the red light “fault” turns on
It may be caused by

• Too much pressure in burner compartment (blower does not work or does not produce
vacuum) , air pressure switch is not well adjusted or defective.

• Gas pressure is too low or not well adjusted or defective gas pressure switch.

• Malfunction of ignition system or detection of flame.

To correct press the red push button “fault” (same one as the “fault” light) for two second.
If the fault is still active and cannot be reset, call for service.

COOKING TIMER

Set the baking time required with the small push button on the timer. The green display is the setting
time and the red display is the countdown time (Ex: 25 minutes = set 2500 on green display).

After setting: Push the START/STOP button then, when the time expires, the buzzer will ring.
Push the START/STOP button again to stop the buzzer.
If you want to restart the time in the middle of the countdown, press on the START/STOP
button.

P.S. The timer is simply a reminder for the approximate duration of the baking time..

POWER FAILURE

The burner, the electric gas valve and the regulator are all designed to be fail safe. Then, there is
no special action to take in case of electrical power failure. Turn off the oven. Never leave the
oven unsupervised when the power is on the unit.
