4. Important Notice –Read carefully before operating
The B 380 warm air heater (WLE) is an oil-fired hot air turbine without heat exchanger in a mobile version.
The hot air turbine must not be placed near explosive or highly flammable materials and must not be used in
explosive and fire-hazardous rooms. It is also prohibited to install it in rooms with a large amount of dust. A
sufficient safety distance from combustible material, such as wood, etc., must be ensured. Good ventilation
of the rooms is a condition. Any handling or transport of the running device must be omitted.
When using the hot air turbine for grain drying, the installation in front of the dry blower must be carried out
at right angles or at a sufficient distance so that the function of the heater is not impaired by the large suction
power of the drying blower.
When using the hot air turbine, the manufacturer's operating and maintenance regulations, the local building
police, fire protection and professional association regulations must be observed.
Page 3 of 15

Operating- and Installation Manual B 380 - Hans Wilms GmbH & Co. KG
When operating the hot air turbine, the accident prevention regulation "Heating, flaming and melting
equipment for construction and assembly work" must be observed, according to which the devices may
only be installed in rooms if
•the appliances are used for combustion sufficient amount of air is supplied and
•the exhaust gases are guided via exhaust trains into the open air.
A sufficient natural air supply for combustion is given if, for example:
•the volume in m3 corresponds to at least 10 times the nominal heat output in kW of all devices in
operation in the room, and
•a natural air exchange is ensured by windows and doors. Agood, natural ventilation is given, if e.g.
•the volume in m3corresponds to at least 30 times the nominal heat output in kW of all devices in
operation in the room and a natural air exchange is ensured by windows and doors, or
•there are non-closable openings for supply and exhaust air near the ceiling and floor,
the size of which in m2corresponds to at least 0.003 times the nominal heat load in kW of all devices
in operation in the room
.
An unfavorable concentration of harmful substances in the breathing air is not to be expected as long as the
MAK values are below and the oxygen content of the air is more than 17 vol. %.
Note: If the two above possibilities for good, natural ventilation are given, it can be assumed that the limit
values for oxygen content and concentration of harmful substances (MAK values) are complied with.
The hot air turbine may only be operated by persons who are instructed in the operation and maintenance of
the equipment.
Persons instructed are those persons who, if necessary, have been trained and informed of the tasks
assigned to them and of any possible dangers.
On construction sites, the device may only be connected via special supply points, generally construction
power distributors with RCDs (VDE 0100, Part 704).
Repair and maintenance work on the electrical equipment may only be carried out by an electrician.
The devices must be tested for their safe working condition according to the conditions of use as required, but
at least once a year by an expert. The results of the examination must be recorded in writing and kept until
the next examination.

5. Functional Description
The unit is equipped with an attached fuel tank, low-maintenance axial fan, a high-pressure atomization
burner with automatic flame monitoring, connection cable with plug, room thermostat socket and quadruple
filter system.
Functioning:
After switching on the device or when heat is required (room thermostat), the fan switches on. After the pre-
ventilation time of about 10 seconds (the control lamp of the control unit flashes red), the solenoid valve
opens the fuel supply to the nozzle. The fuel is atomized via the nozzle and ignited with a fixed amount of
oxygen mixed by an electrical spark.
If the flame burns properly, the control unit takes over the flame and switches off the ignition. The control
lamp (simultaneously reset button) of the controller lights up green.
In case of possible malfunctions or unstable combustion, the device is switched off by flame monitoring.
The interference lamp of the control unit lights up permanently red. A restart can only take place after
manual unlocking (about 2 seconds pressing the reset button) of the controller.
If the device overheats, the safety thermostat (STB) interrupts the current supply to the solenoid valve and
triggers a fault in the control unit due to the absence of a flame.
After switching off, the device runs time-controlled for about 1 minute.
6. Assembly
The device is delivered assembled, and can thus be put into operation. For better drivability with a full tank, it
is recommended to move the chassis (before refueling) as shown in figure 1.
Page 5 of 15
Fig. 1

Operating- and Installation Manual B 380 - Hans Wilms GmbH & Co. KG
Operation with room thermostat:
For temperature-dependent control, room or damp room thermostats with plug and approx. 10 m cable are
optionally available. If a thermostat is to be connected, the bridge plug must be removed from the thermostat
socket, and the thermostat plug must be plugged in there, and fixed with the bracket (Fig. 2). If the
thermostat is not in use, the bridge plug must be plugged back in, as the device will not work without it.
7. Fuel System
- The personnel responsible for refuelling must be qualified and fully familiar with the manufacturer’s
instructions and the applicable regulations regarding the safe refuelling of the heaters.
- Use only the type of fuel indicated on the type plate of the heater. Use the tank filling screen
and do not remove it, for example, to speed up the refueling process!
- Before refuelling, turn off the heater and wait for it to cool down.
- The storage tanks for the fuel must be located in a separate room.
-All fuel tanks must maintain a sufficient safety distance from the heater in accordance with the applicable
regulations.
- The storage of the fuel must be carried out in accordance with the applicable legal regulations.
8. Set Up
The B 380 heater is installed at the place of use. Fill the fuel tank with clean, light heating oil EL or
comparable fuel. Do not overfill, maximum 95 liters.
The electrical connection is made via an attached power cable with safety plug to a 230V/50 Hz
power supply. On construction sites, the device is only connected via special supply points, generally
construction power distributors with FI-protection switches (DIN VDE 0100-704).
When using a room thermostat, place it in a suitable place (preferably not in direct hot air flow) and
connect it to the thermostat socket after the bridge plug has been removed. The thermostat is equipped
with a cable length of about 10 m, and should be hung within the room to be heated. If the set temperature
is above the actual room temperature, the heater (when the power button is switched on) starts
automatically and switches off again automatically when this temperature is reached.

Operating- and Installation Manual B 380 - Hans Wilms GmbH & Co. KG
9. Operation
Starting:
Switch the power button to position "1", if a room thermostat is used, set it to a temperature above the
actually existing room temperature.
The blower motor starts, and after a pre-aeration phase of about 10 seconds, the flame is formed.
Stopping:
Switch the power button to position "0", if a room thermostat is used, set it to a temperature below the actual
room temperature. The device runs time-controlled for about 60 seconds to cool down. Only when the follow-
up is finished, the device may be disconnected from the mains!
Malfunction:
In case of an empty tank, abnormal combustion, dirty photocell, overheating or other defects, the control unit
detects a problem, interrupts the operating process, and indicates a fault caused by permanent red light of
the indicator light. This also serves as a reset button for acknowledging the fault, which is retained even after
the mains voltage has been switched off.
First determine and eliminate the cause of the fault before you disturb the control (by pressing the remaining
button for about 2 seconds).
10. Maintenance
Depending on the conditions of use and frequency of use, the maintenance intervals can be very different.
However, the device should be cleaned at least once a year and tested for function and safety. Maintenance
and repair work should only be carried out by persons with the necessary expertise.
Clean the fan wheel, the burner, the storage disc, the electrodes and the fuel filters in the tank filler neck,
filter housing, fuel pump and nozzle.
Replace defective or worn parts with original spare parts immediately. When ordering spare parts, always
specify the device type and serial number.
During cleaning work, always disconnect the device from the mains and work only on the cooled device.
Note that the device does not burn correctly when the burner cover is open because of the lower amount of
air.
Check the fuel tank and the filter housing A (Fig. 3) for contamination and condensation, and empty and
clean if necessary. Clean the filter insert B with appropriate means or replace it. Check the condition and
correct fit of the seals and replace them if necessary. A repair kit is available for this purpose (spare parts
list).
Check - and correct, if necessary - the adjustment of the air volume (Fig. 4), the oil pressure and the
electrodes (Fig. 5 + 6), and pay attention to the installation of a burner nozzle of the correct type, size and
spray angle. The correct values can be found in the drawings, spare parts lists and technical data.
