Important Notice!
1 Use only clean (if possible filtered) Heizöl EL (Diesel)
2 Clean fuel filter regularly
A T T E N T I O N :
Notice: Heizöl EL changes viscosity in low temperature
This heater is standard equipped with a fuel preheating device This
requires also during the heating interruptions (during the night, on
weekends) tension, so it remains effective Therefore, leave the plug
into the socket
When ordering spare parts please give the type, serial number of the
heater and the part number, otherwise a correct delivery is not
possible
The admissible ambient temperature for securing the function of the
control is – 15°C and max + 50°C This is to be especially taken
into consideration whilst drying grain or using the heater outdoors
The heater resp the flame control has to be protected against direct
influence from the bright sun light
Technica specifications are subject to changes without any notice!

FUNCTIONAL CHARACTERISTICS
The heater is equipped with mounted fuel tank, low-maintenance axial fan,
high pressure spraying burner with automatic flame control, cable with
plug, socket for room thermostat and quintuple filtersystem
Operating System:
The fan runs after starting the heater or in case of heat demand
Fuel is drawn from the tank and pumped into the solenoid valve The solenoid
valve opens and allows fuel to flow to the nozzle The spark between the
electrodes will ignite the atomized fuel The light of the flame activates the
photo-cell and ignition switches off automatically
In case of disturbance or instable burning the flame control switches off
the heater The operation lamp of the burner control flashes A restart
can only be made after reset of the burner controler In case of overheating
of the machine the safety thermostat (STB) switches off and blocks all
functions of the machine
The manual unlocking of the safety thermostat can only be done after
elimination of the fault and cooling of the heater
Switching to position „O“ closes the solenoid valve and the flame is
extinguished The fan will keep running until the cooling cycle is complete

READ CAREFULLY BEFORE STARTING YOUR HEATER!
Important Notice!
This unit is a space heater with indirect heating, heat exchanger and exhaust
The heater may not be set up near explosive or flamable materials and may not
be used in explosion or fire endangered rooms It may also not be used in areas
with high dust development The heater should be positioned at adequate distance
to flamable material such as wood etc It is essential that there is a sufficient ventilation
of the room The heater may not be worked on or transported during operation
If the heater is used for drying of grain the set-up has to be in a correct angle in front of
the radial fan or alternatively with sufficient distance This has to be done so that the
function of the heater is not influenced by the immense suction of the radial fan
The heater is standard equipped with a fuel pre-heating device This requires also
during the heating interruption (during the night, on weekends) tension so it remains
effective Therefore leave the plug into the socket

1. Starting
Only well instructed persons should start and work with the heater
Before starting the heater check for obvious defaults, proper setting up and as well the
electr supply
a) Ensure a stable set up of the heater
b) Fill the tank with clean Heizöl EL (Diesel)
c) Install exhaust system according to the drawing, see page 10
d) Power supply: Connect heater to the 230 V - 50 Hz power supply
e) Put room thermostat on suitable place in the room and set to desired
temperature (Must be above ambient temperature)
A T T E N T I O N
The heater is standard equipped with a fuel preheating device The function of the
preheating is only given if the heater remains on stand-by with plugged-in electrical
plug for appr 15-20 min before the first starting
During this time the oil is preheated so that the sorting out of paraffine is avoided
During service always obbey the surface temperature from the fuel preheating device
Disconnect the heater first from the power supply and let it cool down (danger of
burning)
Operation "Heating without room thermostat"
Set main switch to position "1"
The automatic heating operation is started when the switch is set to position "1"
The heaters works continuously, the delivered blind plug must be connected with the
thermostat socket
Operation "Heating with room thermostat"
The heater works automatically and depends on the temperature Remove the blind
plug, connect the plug of the room thermostat with the thermostat socket Adjust
required temperature on the room thermostat, turn again main switch to position "1"
Set room thermostat to desired temperature
Operation with warm air hose
The device can be operated with a warm air hose (max length 7 60 m) This is only to
be used in connection with a hose adapter It is essential to ensure proper installation;
reducing the diameter can lead to overheating and shutdown of the device (safety
thermostat)!

2. Stopping of the heater
Set main switch to pos "O", or reverse the thermostat below the present state
If the heater has been running on position "Heating" (Heizen) it has an automatic
cooling of the heater until it completely shuts off
Important!
Pull the main plug only after the heater has cooled down and stopped
Before repairing or servicing always pull the main plug
3. Safety and contro devices
In case there is no flame - for example caused by lack of fuel - the oil burner relay
shuts off the heater The control lamp on the side of the burner reset button lights up
After the cause of the malfunction has been cleared the reset button can be pushed,
and the burner can be restarted
In case the limit switch has shut off, check the malfunction and eliminate it
(overheating)
After eliminating of the overheating unlock the limit switch by removing the cap on the
right side and pushing the unlocking key (after cooling down of the heater) Then screw
on the protection cap
Room thermostat
The thermostat has a temperature regulation range of 5° C - 30° C and shuts the
burner off after the preset temperature has been reached The fan continues to run
in order to cool the heater down to a temperature of appr 30° C before it stops After
the room temperature drops several °C the heater automatically starts running again

4. C eaning
The heater should be cleaned minimum once a year including combustion chamber
and burner head Also the fuel filter should be cleaned minimum once a year or even
be changed depending on contamination level
C eaning of the fue tank
If the heater has not been used for a longer period of time and also after each heating
period clean the fuel tank by removing the drain plug on the bottom of the tank
Collect the dirty fuel in an external container
Rinse the fuel tank several times with clean fuel, no dirt particle should remain in the
tank Check the gasket of the drain plug and replace it if necessary, then install the
drain plug again
Fill the tank with the clean fuel (Heizöl) and let the heater burn for 3 minutes, and the
pump will be protected against corrosion
Before repairing or servicing the heater pu the main p ug!
Repair or service of e ectrica components may on y be made by authorized
specia ists!!!

6. Important Notice
These units are oil fired space heaters, equipped with a chimney connection If
connected to a chimney the installation should be made only according to the below
drawing
The connection should be made only with a fixed chimney according to the regulations
or an installed exhaust pipe as shown in the drawing
Never start the heaters connected to just an exhaust pipe which has been lead through
the wall
Use it only with an additional exhaust pipe, minimum above the ridge In case of
horizontal outlet through the wall, use only with T-shaped pipe, refer below drawing
Top of exhaust pipe or chimney
should be 0,5 m above ridge
The horizontally laid exhaust pipe up to the actual chimney must be installed with a
slope of at least 10%
