5.2.4 Temperature regulation
NOTE!
Before baking the pizza, the oven should be pre-heated to the desired
temperature!
Connect the device to the power supply.
Set the desired temperature for the selected upper/lower heating element using the
appropriate temperature regulators. The temperature of the pizza oven can be
adjusted within the range from 85 °C to 450 °C. When baking pizza it is
recommended to set the temperature in the range from 300 °C to 400 °C.
Upper and lower heating element control lights come on during pre-heating of the
device.
Value of the temperature inside the baking chamber may be read on the temperature
indicator of the device (except for pizza ovens, code-no. 2002018 and 2002028).
When the set temperature has been reached, the control light will go off. When the
temperature in the baking chamber decreases, the control light will come on again
and the heater will start heating the baking chamber up to the set temperature.
5.2.5 Baking pizza
After pre-heating the backing chamber, open the oven door using door handles.
Place the prepared pizzas on the chamotte plate and close the door.
Do not leave the pizza oven unattended during its operation. Observe the baking
process through the window in the oven door,
When the baking is finished, remove the pizzas from the oven.
WARNING! Danger of burns!
To avoid burns when removing pizza from the oven, use
the heat-resistant gloves protecting hands and wrists.
Furthermore, use kitchen utensils with long handles
(e.g. pizza shovel).
