7. INSTALLATION
When installing the heater, all local regulations are to be com -
plied with, including regulations referring to national norms.
► Place the heater on flat surface made of concrete.
► Level the device in order to check if the heater is levelled cor -
rectly, place the vaporising pan in the lower part of the combus -
tion chamber and pour a small amount (approximately 250ml)
of diesel oil onto it. The oil should stay exactly in the middle of
the pan.
► Install current stabilizer (valve) on the combustion chamber’s
outlet pipe in order to maintain constant draught inside the pipe
during the operation.
► Install at least six meters long, smooth and temperature re -
sistant horizontal flue (not aluminium flue) in order to provide
optimum draught.
► Check tightness of all joints, if necessary use the insulation
tape.
► Make sure that the vaporising pan is placed centrally in the
combustion chamber.
► Place the upper ring inside the combustion chamber with
flange facing upwards and install the hot air pipe.
► Check the power (220-240V/50Hz) and connect the heater
to the power outlet. Neither fan nor the pump should become ac -
tive because the burner has not been switched on and the heat
has not been produced yet.
► The heater should be placed away from combustible materi -
als.
VENTILATION FANS WORKING IN THE SAME
ROOM OR AREA AS THE HEATER MAY CAUSE DIS -
RUPTIONS.
FITTING THE FLUE
To ensure the right combustion appropriate fitting of the flue in
necessary. The following recommendations should be adhered
to when fitting the flue:
► Minimum flue diameter - 150mm.
► Check tightness of joints between flue elements.
► Minimum flue height- 5m.
► The inside of the flue should be insulated (double skinned).
► The tube should be in free air (the tip of the flue should be
above the rooftop).
► If possible, all sections of the flue should be in vertical posi -
tion, horizontal positioning should be avoided, as well as bend -
ing of the flue. However, if it is necessary to bend a flue (for
example a flue bent in two places when it runs through a wall or
a window), the maximum angle is 45° with minimum height of
the flue increased to 7m.
► Minimum flue draught of 16Pa with nominal heat.
► The device cannot be connected to the joint combustion out -
let system.
CAUTION!
WHEN INSTALLING THE COMBUSTION OUTLET SYS -
TEM IT IS RECOMMENDED NOT TO PLACE FLUES
IN HORIZONTAL POSITION. IN ORDER TO GUARAN -
TEE FREE MOVEMENT OF GASES, THE ANGLE OF
FLUE SHOULD NOT EXCEED 45°. THE FLUE OUTLET
MUST BE ABOVE THE ROOFTOP.
FLUES RUNNING THROUGH THE CEILING, WALLS
OR THE ROOF, MUST BE INSULATED IN ORDER TO
PREVENT FIRE. IT IS RECOMMENDED TO USE DOU -
BLE SKINNED FLUE IN PLACES WHERE THE FLUE
IS LIKELY TO BE TOUCHED BY THE GENERAL PUB -
LIC AND ON THE OUTSIDE OF THE BUILDING IN
ORDER TO GUARANTEE GOOD DRAUGHT AND PRE -
VENT CONDENSATION. NO MATERIALS SHOULD
BE PLACED CLOSE TO THE HEATER, EVEN INCOM -
BUSTIBLE ONES. FREE AIR MOVEMENT SHOULD
BE PROVIDED TO ASSURE PROPER COMBUSTION
PROCESS.

CONTROL PANEL
The control panel of universal oil heater is equipped with two
buttons (start, stop), potentiometer (min. 22kW, max. 30kW),
toggle switch (heating oil/ universal oil), enabling the user to
control the operation of the heater and four diodes signalling the
operating modes of the device.

► The heat is produced during gas combustion when oil is
heated up to a high temperature. When connecting the heater
to power network, the device is in stand-by mode (Stop). Heat is
not produced and fan and pump are not working. Pressing the
Start button triggers the green diode to turn on and the heater
goes into the heating up mode. Once the burner is heated up to
40°C the joints of thermostat placed next to combustion cham -
ber clutch activating the oil inlet pipe and blower fan; these are
signalled by the yellow diode on the control panel. At the begin -
ning smaller amount of oil is required for at least 30 minutes,
