• Before the start-up check the correctness of the installation, stability, and levelling of the device, and if the electric and gas connections are correct.

• Do not cover the ventilation slots.

• The device elements removed during the installation and connecting must be replaced.

• Before the device operation clean it according to the instructions in section 6 “Cleaning and maintenance”.

Operation indicator (green)

Make sure that all knobs are in “

• Open the gas valve before the device.

• In order to ignite the burner press appropriate knob and rotate it counterclockwise to the position with the ignition flame symbol .

• Hold the knob pressed for 3-4 seconds and ignite the flame with the igniter.

• Hold the knob pressed for a few more seconds to obtain the flame continuity.

• In order to put out the flame turn the knob to “

• At the end of the work day close the gas cut-off valve. CAUTION! In case of longer standstill or damage of the device close the main gas valve before the device.

Instructions and advices

• Avoid the flame exceeding the pot (frying pan) edge.

• When the food starts to boil reduce the flame to the lowest level so it will not be extinguished by the boiling over food.

• Never leave the device unattended during heating of fats and oils as they may ignite when overheated. There is the fire hazard!

• Use only pots with flat bottom.

• Place the pots on the grate in such way that the flame is located in the centre.- 44 -

• Before starting the oven make sure that there is only the equipment provided for a given cooking/baking process inside (usually the grate – shelf on which the utensils or the baking tray with food are placed is sufficient).

• Before the operation wash all parts in warm water with the gentle washing agent.

• Connect the device to the appropriate socket and heat the empty oven at the highest temperature setting of 300 ºC for at least 30 minutes. Due to heating of the insulation materials and protective substances used during the metal processing an unpleasant odour may occur, which should not take place during the further operation. After heating ventilate the room with opened oven door.

• In order to obtain the optimal cooking/baking effect select the temperature and time accordingly for each food.

Temperature adjustment

• Use the temperature controller knob to select tempera-- ture for a given food. The following settings may be used: 50, 100, 150, 200, 250, 300 °C.

• The orange control light illuminates during the whole heating phase. After reaching the preset temperature the control light goes off.

• Now place the prepared food in the preheated oven.

• When the temperature in the oven drops the operation control light will come on and the device will be reheated to the preset temperature.

• The fan assuring the uniform distribution of hot air in the oven operates for the whole time.

• The device is equipped with the time setting function. The operation time may be adapted to the prepared food with use of time controller knob in range of 20 – 120 minutes.

• After that time the oven turns off and the food may be removed from the chamber.- 45 -

• When it is not required to set the specified operation time for the oven, use the position for the continuous operation . Observe the baking process and turn the device off when the food is prepared. CAUTION! When the oven is not used, turn the function selection knob to position “●“ (OFF).

• There are 4 levels available in the oven: 1 bottom level, 2 middle levels, 1 top level.

• The best results are obtained for the middle levels.

• In order to assure the sufficient air circulation leave the distance of at least 40 mm between the food placed on the shelves.

Instructions and advices

• Due to sizes of food and use of various utensils from various materials of various thickness (ceramics, glass, aluminium, steel) there may be deviations from times specified in the recipes.

• In case of delicate food or prepared with use of raising agents avoid opening the oven door to keep the internal temperature stable.

• In order to save energy during long cooking/baking processes the oven may be turned off a few minutes earlier than specified in the recipe and do not open the oven door to use the remaining heat.- 46 -
