machine operation. Before proceeding the oven temperature must be at 350° C for roughly 60 minutes (setting
350° on the top and on the bottom as well), for an easy baking scoriae carbonization. Once the temperature
is reached, switch off the oven and wait until the temperature drops to roughly 100°C (the best temperature
for cleaning). At this stage disconnect the electric power supply. After dressing in gloves and suitable dresses
as protection from burns, open the door and with a brush in natural fiber with a long handle, proceed to a first
removal of baking fragments from the refractory stones, then take them out by a suitable vacuum cleaner. At
the end, clean the refractory stone with an humid cloth.
External cleaning of the oven
Oven external areas cleaning, external parts in stainless steel, door glass, and switch panel, must be carried
out at cold oven and at disconnected electric power supply. Use a sponge or a soft cloth, not abrasive,
slightly humidified with water or possibly with a neutral detergent not corrosive. In any case, do not use water
jets which can penetrate through the electric parts and easily damage them, as well as creating hazardous
conditions.
