area is free and that there are no people, animals or objects that could be hit and
damaged by the pallet or the truck.
Pallets must be rmly secured at all times when being moved. They must be rmly xed
to the transport vehicle and then unhooked before being moved via mechanical support.

Precautions
NEVER move the oven when it is hot.
All products are manufactured and veried by TEK REF S.r.l. before being shipped and delivered to the customer.
When used correctly, the oven is designed, manufactured and tested to meet all specic standards (see declaration of
compliance).
Choosing an area for use
The Subito Cotto MINI oven can be used both indoors and outdoors. For internal use, the room must be properly ventilated. For
outside use, choose an area that is not windy. The Subito Cotto MINI is made of materials resistant to atmospheric agents, but
during periods of non-use, it is recommended you cover it up.
• Place the oven on a horizontal surface sturdy enough to support its weight
• Place the oven somewhere far away from any combustible material.
• Ambient temperature: from -20 °C (68 °F) to +50 °C (122 °F);
• Humidity: ≤ 90% without condensation;
• Atmospheric pressure: 86 kPa ~ 106 kPa
• Keep the oven away from external heat sources, open ames and atmospheric agents.
WARNING
IMPROPER PLACEMENT AND/OR MAINTENANCE OF THE OVEN WILL INVALIDATE THE TERMS
OF WARRANTY.
PLACEMENT
Conguration
The Subito Cotto MINI is congured for standard for use with LPG gas. It can be
congured for methane gas on request and before purchase. A low pressure
regulator must be used to connect the Subito Cotto MINI to the LPG cylinder.This
regulator must have the following indicators:
• Flow rate: 7 kg / h
• LOW Pressure: 30 mbar
Connect the gas tube by screwing on the nut with the left threading into the
appropriate coupling under the oven.Use a suitable seal and tubing that complies
with regulations.
First Ignition
• Please take utmost care when igniting the oven for the rst time - the ame
should be kept very low, not exceeding 100/120 °C (212/248 °F).
• The duration of each ignition should be increased day after day, so as to
obtain a gradual increase in temperature, for a period of ve or six days
or until the water contained in the oven is totally evaporated and until the
oven reaches 420/450 °C (788/842 °F).
The rst few ignitions remove the moisture from the oven that was accumulated during production and transport. Switch the
Subito Cotto MINI on for the rst time for at least three hours, this pre-heating phase is very important.
WATER LEAKAGE ON FIRST IGNITION IS COMMON AND DOES NOT INDICATE A DEFECTIVE PRODUCT
Note: Due to thermal expansion,small cracks may appear in the dome or hearth during polymerizations.This is normal and also
does not indicate a defective product.
WARNING
QUICK IGNITION WITH A RAPID INCREASE IN TEMPERATURE CAN LEAD TO SEVERE DAMAGE TO
THE COOKTOP, RAISING WEDGES IN THE BASE AND/OR BREAKAGE OR DISPLACEMENT OF THIS
BASE.

WARNING
NEVER USE ANYTYPE OF LIQUID FUEL,EXPLOSIVE MIXTURES OR CHEMICALPRODUCTS BASED ON
OIL, ALCOHOL OR GASOLINE TO IGNITE OR STOKE THE FLAME. KEEP ALL FLAMMABLE/EXPLOSIVE
LIQUIDS WELL AWAY FROM THE OVEN WHEN IN USE.
NOTE
THE TEMPERATURE DURING USE VARIES FROM 200 - 450 °C (392 - 842 °F) ACCORDING TO
THE TYPE OF FOOD YOU WILL BE COOKING.
Turn on the Subito Cooked MINI via the piezoelectric, keeping the gas regulation knob pressed in. The pilot ame will light up.
Wait a few seconds with the pilot ame on. Now release the adjustment knob and turn it to the desired ame intensity.
To bring the Subito Cotto MINI to the desired cooking temperature more quickly, you can use the oven door to increase air
intake. Warning: the door will quickly become very hot and you will need to use a protective glove or mitt to avoid burning
yourself.
Do not leave the oven switched on for longer than two hours with the door closed. The temperature increase too much for any
type of cooking and the oven could get damaged.
Once the desired temperature has been reached, the oven can be used without the door.
In case of an emergency, immediately close the gas cylinder, remove the door if it is inserted, remove any food that’s inside the
oven and any ammable objects from the vicinity. Ventilate the premises thoroughly.
