• temperature 0..30°C
• relative humidity 5..85%
• pressure 800..1200 hPa
• degree of protection against environmental influences IP65
• good ventilation of the heated space

Characteristic features of the controller

• three-stage power regulation of the furnace 8-19-30 kW,
• preservation of settings in the event of a power supply failure.

Security aspects

The 8-30 universal oil heater is powered by an alternating current network of 230V / 50Hz. It is equipped with three sensors ensuring safe and economical operation of the device.

1. The bimetallic sensor, located at the furnace chamber, reacts by shorting the points in the thermostat when the temperature exceeds 40°C and opening the points when the temperature drops below 35°C.
2.  The bimetallic sensor, located near the supply fan, whose threshold temperature is 100°C, opens the points when this temperature is exceeded and causes the heater to  go into emergency mode, disconnecting the fuel supply, thus protecting the fan against overheating or melting of its elements.
3. Micro-switch, weight sensor located under the combustion chamber. Filling the bowl causes the heater to go into emergency mode immediately, disconnecting the fuel  supply. This prevents it from spilling out excess non-vaporized fuel outside the combustion chamber, eliminating the possibility of its ignition outside the device. Connection of the heater control panel with other system components (sensors, pump, fan) is made at the factory and during normal operation, for safety reasons, it is  not allowed to interfere with the covered and sealed part of the heater controller and to violate the integrity of the wires. Any action of an unauthorized person may result in electric shock (230V AC, 50Hz) and burns

7a. Installation of the chimney
A properly constructed chimney installation is necessary to ensure proper combustion.
When performing it, follow the recommendations below:
– the diameter of the exhaust outlet from the device is 130 mm,
– the recommended diameter of the chimney pipe is 130 – 150 mm,
– the minimum height of the chimney with a diameter of 150 mm is 5 meters,
– check the tightness of connections between the chimney elements,
– the wind should freely blow the chimney outlet from all directions – the end of the chimney pipe should be approx. 1 m above the top of the roof,
– if possible, all sections of the chimney should be vertical – avoid horizontal sections, as well as bends of the chimney pipe – if bends are necessary (e.g. two bends in the case  of leading the pipe through a wall or window) then the maximum bend angle must not exceed 45°, and the minimum height of the chimney should be increased to 6 meters.

ATTENTION

When installing the flue gas discharge system, it is recommended to avoid horizontal sections of the chimney pipe.
In order to ensure free outflow of gases, the angle of possible bending of the pipe should not be greater / less than 45°. The chimney outlet must be higher than the top of  the roof, preferably approx. 1 m.
The places where the chimney passes through the ceiling, walls or roof must be insulated to avoid fire hazards. It is recommended to use a double-layer insulated chimney  pipe wherever there is a possibility of touch contact and outside the building to ensure constant good draft and prevent condensation. Do not place any materials near the  heater, even non-flammable ones.
Constant access of air necessary for the proper combustion process must be ensured.

---|---

The process of generating heat is carried out by burning gas, which is produced by oil heated to high temperatures. When the device is connected to the mains, it is in standby  (Stop) mode and no heat is produced, neither the fan nor the pump is running.
Pressing the button marked NETWORK in position 1 causes the heater to be ready for firing up (you can see firing up at point 9a). After firing up and heating the heater to a  temperature of approx. 40 ° C, the oil feeding pump, and the supply fan are turned on.
Due to the lower demand for oil when the furnace is not heated, the device should operate at 19kW for at least 15 minutes. After approx. 15 minutes of operation, when the  furnace bowl is sufficiently warmed up and is able to evaporate a larger amount of oil, the power of the device can be switched to 30 kW or less 8kW. When working at the highest power, approx. 3 liters of oil is fed to the furnace.
The heater is turned off by pressing the button marked NETWORK in position “0” on the control panel. At this point, the pump is turned off. The supply fan works until  the furnace temperature drops below approx. 35°C (Stopping). After reaching a lower temperature than 35°C, the stove returns to the Stop phase.

The heater can be turned off automatically in the following cases:
– overheating of the combustion chamber,
– overflows.
The overheating condition is generated by a bimetallic sensor located near the fan. The opening of the contacts signals that the threshold temperature value has been  exceeded. The control system turns off the fuel feeding pump and the fan works until the furnace temperature drops below 35°C. Upon reaching a temperature
lower than 35°C, the furnace returns to the Stop phase.
To return to normal operation, wait until the furnace cools down (turning off the fan and cooling down the chamber) and press the button on the bimetallic sensor housing  (reset). Clean the furnace bowl, taking into account that the bowl and the deflector may still be hot due to the fact that cast iron maintains the temperature for a long time. The heater can then be restarted as described in point 9a.
The overflow signal is generated by a mechanical sensor located under the overflow tank. The opening of the contacts signals that the tank is overfilled and turns off the fuel  feeding pump, and the fan works until the furnace temperature drops below 35°C. Upon reaching a temperature lower than 35°C, the furnace returns to the Stop phase.
To return to normal operation, wait until the heater has cooled down (the fan is turned off and the chamber has cooled down), empty the overflow tank, clean the furnace  bowl and the combustion chamber, taking into account that the bowl and deflector may still be hot because cast iron maintains the temperature for a long time. The heater can then be restarted as described in point 9a.

ATTENTION!!!

DO NOT ADD OIL TO THE FURNACE AND LIGHT WHILE THE FURNACE CHAMBER OR BOWL IS STILL HOT !!!
ALWAYS WAIT FOR THE FURNACE PLATE TO COOL DOWN COMPLETELY.
IF YOU DO NOT FOLLOW THE ABOVE RECOMMENDATION, YOU MAY CAUSE UNCONTROLLED IGNITION OF OIL FUMES AND BURN!!!

9a. Starting the device.

• if necessary, drain the water from the fuel tank and fill it with oil (e.g. used oil),
• check the correct operation of the overflow protection mechanism by weighing the cup lever downwards and its spontaneous return, confirmed by a characteristic sound “click”,
• check if the burner of the device is pushed as far as possible to the cover of the device (if it is not, it should be pushed in),
• insert the plug of the power cord into the mains socket (230V / 50Hz),
• tilt the upper part of the heater cover and remove the combustion chamber cover, then remove the cylinder and deflector (if necessary, thoroughly clean the combustion  bowl and the base on which it is placed, as well as the entire combustion chamber with the sleeve and deflector),
• verify if the furnace bowl is cool and clean, then pour about 250 ml of heating oil or diesel fuel into it,
• assemble the ring and cylinder,
• light the oil using a piece of paper crushed into a ball, set it on fire, and then throw it on the hearth bowl,
• put on the combustion chamber cover, close the upper part of the heater cover,
• press the button marked as NETWORK to position 1 and turn the knob of the power setting to the position 19 kW.
• after approx. 10-15 minutes, depending on the room temperature, the fuel pump and the fan are turned on. The heater must run at this power for a minimum of 15  minutes. After approx. 15 minutes of operation, when the furnace bowl is sufficiently warmed up and is able to evaporate a larger amount of oil, you can switch the power of the device to 30 kW or reduce it to 8kW .

9b. Shutting down the device
To turn off the device and end the heating process, on the control panel turn the power setting knob to the fan position and switch the button marked as NETWORK to  position 0, which will turn off the lamp. The pump will stop feeding fuel to the combustion bowl, and the fan will continue to run until the heater cools down. The  extinguishing process depends on the room temperature and the degree of heating of the combustion chamber and may last from 20 to 40 minutes.

DO NOT disconnect the device from the power supply when the fan is running! Wait for the heater to cool down. The heater is turned off automatically. It should be  emembered that after the device is turned off, the cast iron bowl maintains a higher temperature for some time (depending on the ambient temperature) and the heater cannot be re-ignited until the bowl is completely cold!
DO NOT throw a hot bowl into the snow, or pour cold water over it to accelerate cooling – a hot bowl, due to a large temperature difference, will crack and will be unusable !!!
9c. Maintenance

The heater requires very little maintenance. Following the manufacturer’s recommendations in this regard will ensure failure-free and safe operation of the device:

• clean the furnace bowl and other elements of the combustion chamber (cylinder, deflector, and cover) daily,
• check the overflow pipe for blockage (the pipe in the lower part of the combustion chamber, directly above the overflow bowl), clean if necessary,
• at least once a week clean the base of the combustion chamber (the element under the furnace bowl),
•  check that the air inlet openings in the lower and upper parts of the combustion chamber are not blocked,
• clean the fuel feeding pipe (burner) at least once a week, the maximum working time without cleaning the furnace bowl is approx. 7-14 hours. (depending on the combustion oil used),
•  during the heating season, clean the fuel tank and the oil pump filter,
• if the heater will be off for a longer period, carefully clean the combustion chamber and the day tank, then protect them against corrosion by coating them with a thin layer of oil.

SEASONAL INSPECTIONS ARE RECOMMENDED AT THE AUTHORIZED SERVICE
