Description of Unit
The units are mobile, directly combusted hot air heaters
(WLE) with heat exchangers and a chimney connection
for commercial use.
They are directly combusted with EL heating oil or diesel fuel and designed for fully automatic, universal,
problem-free use.
The units are only operated with a separate forced-air
oil burner. The units are equipped with an electrical oil
preheater via the nozzle stock.
The units are equipped with a low-noise, maintenancefree, high-performance axial ventilator, a room thermostat socket, a connection cable with a plug, and a drum
fitting.
The units correspond with the basic safety and health
requirements of all pertinent EU regulations and are
easy to operate.
Areas of application
The units are mobile, directly combustible hot air heaters
that supply instantaneous heat. They are only used for
commercial purposes.
Among other things, the units can be used in the following areas:
− Drying of new structures
− Spot heating of outdoor workstations
− Spot heating of workstations in open production
rooms and halls not at risk of fire
− Heating of closed and open rooms, on a permanent
or temporary basis
− De-icing of machines, vehicles, and non-flammable
warehouse goods
− Temperature control of parts at risk of frost and
greenhouses
Function
If the unit is switched to heating mode, the forced-air oil
burner starts automatically. In fully automatic heating
mode, the forced-air oil burner starts only when heat is required.
After the burner has run for a short time, the temperature control thermostat "TR" (set temperature between
35°C and 40°C) automatically switches on the air supply fan. Hot air is blown out.
When the room thermostat is in operation, the process
above is automatically repeated depending on the
amount of heat required
The temperature monitor "TW" (set temperature between 80°C and 85 °C) monitors the internal temperature of the unit.
After the unit has been shut down using the operating
switch or by the room thermostats, the air supply fan
continues to run for a certain period of time to cool the
combustion chamber and the heat exchanger and then
shuts down. This process may repeat several times.
.

Monitoring unit operation
All functions of the unit are fully automatic and monitored for safety by the safety devices and the automatic
burner relay (part of the forced-air oil burner).
If the flame burns irregularly or goes out, the unit is
switched off by the automatic burner relay. The control
lamp on the control panel and the malfunction lamp of the
automatic burner relay light up.
Before the unit can be restarted, the automatic burner relay
must be released manually by pressing the external reset
button on the control panel or the reset button on the automatic burner relay.
The temperature control thermostat (TR) regulates the
operation of the fan. The temperature monitor (TW) limits or regulates the temperature of the unit in heating
mode.
The safety temperature limiter (STB) interrupts the
heating mode when extreme overheating occurs or if
the temperature monitor (TW) breaks down or becomes
defective. The STB can be released manually only after
Before the STB is released to begin operation
again, the causes for the activation of the STB
must be localised.

Installation Regulations
When the equipment is in use, the safety guidelines of
the employers' liability insurance associations, the respective country construction ordinances, and the burning appliance regulations basically apply.
◊ Avoid underpressure or overpressure in mounting
rooms since these states always lead to combustion-technical problems.
◊ Make sure the fresh air supply has been adapted to
the respective fan output (see model plate).
The forced-air oil burner must be equipped with a
separate combustion air supply if necessary.
Outdoor installation
◊ Due to the operation of the equipment, no dangers
or unreasonable nuisances may arise.
◊ The equipment operator must guarantee that unau-
thorised persons cannot manipulate the equipment
or the energy supply.
◊ Because rain and snow can be pulled in through the
supply air fan, a suitable protective covering should be
used.
Installation in closed, well-ventilated rooms without
a chimney
◊ The equipment may only be operated when the mini-
mum amount of air required for combustion according to § 38 Sect. 4 (page 5) is supplied.
◊ A safe exhaust of the waste gases is to be ensured
to exclude an inadmissible pollution of the room air.
Fresh air is supplied from below.
Waste gases are expelled upwards.
Safety Devices
The equipment has the following safety or monitoring
devices:
◊ Temperature control thermostat (TR)
◊ Temperature monitor (TW)
◊ Safety temperature limiter (STB)
Temperature control thermostat (TR)
The temperature control thermostat switches the circulating fan on and off. The switching point is set in the
switch box using the "Scale 21 – 60" controller.
Setpoint approx. 35 – 40°C.
Temperature monitor (TW)
In heating mode, the temperature monitor limits both
the temperature of the unit and of the air being blown
out. The switching point is set in the switch box using
the "Scale 34 – 110" controller.
Setpoint approx. 80 – 85 °C.
Safety temperature limiter (STB)
The STB controls the temperature monitor. The switching
point has a permanent setting.
The burner is prevented from being restarted if the STB
is activated.
After the cover next to the control panel is removed, the
reset button must be pressed from the outside.
After the STB has been reset, the cover must be remounted.
Information on the safety devices
Before an STB reset, check the operating conditions
to ensure that the STB temperature is not exceeded
again.
Safety distances
◊ To guarantee safe equipment operation and mainte-
nance, a safety distance of 1.5 metres around the
device must be observed.
◊ The floor and ceiling must be fire-resistant.
Heating rooms
◊ The equipment may be used for room heating only
with a room thermostat (accessory).
◊ The supply of the fresh air required for proper com-
bustion must be guaranteed.
Electrical connection
◊ The equipment is operated at 1~ 230 V/50 Hz.
◊ The electrical connection of the equipment must be
performed at a certain supply point with an earthleakage circuit breaker according to VDE 0100 § 55.
◊ Suitable cable extensions may be used only when
unrolled.
The safety devices are equipped with a sensor monitoring feature and are resistant to cold down to -20°C. Below -20°C, it switches off; when the temperature rises
above this temperature, it switches on again.
When the sensor or capillary tube is damaged or when
an excess temperature of approximately 220°C is
reached, the filling medium is emptied and the safety device switches off. The controller is no longer operable
and must be replaced.
If it is necessary to replace the STB, only the original
REMKO spare part should be used.
◊ Make sure to install and mount the device carefully.
◊ Do not bend the capillary tubes in the direct vicinity
of solder points.
◊ When installing the capillary tubes, be careful not to

Chimney
When the units are operated outside or in open spaces,
you do not need a chimney. We recommend using a onemetre-long chimney pipe with a rain cover at the top to
(see Example 2) to prevent the penetration of rainwater
and dirt.
If the unit is used as a room heater, the waste gases
must be conducted outside.
Make absolutely sure that counterpressure is not
created by an improperly installed chimney.
◊ The chimney pipe parts must be laid in such a way
that no counterpressure can arise.
◊ The unit operates without malfunctions if the chim-
ney has been installed at an incline and assembled
with vertical end pipes.
◊ The chimney must reach at least beyond the gutters,
but preferably above the top of the roof to prevent
counterpressure caused by weather conditions (e.g.
wind).
◊ All chimney pipe parts must be securely fastened.
They may not be smaller in diameter than the chimney connection of the unit.
◊ A minimum distance of 0.6 m to flammable objects
must be maintained.
◊ Chimney pipe parts and fasteners are available as
accessories if required.
When a chimney is used, the adjustment of the
burner must be adapted accordingly.

Hot air distribution
The units are equipped with a high-performance axial
fan. This fan has been designed to transport the hot air
directly and effectively.
The distribution of the air should preferably take place
using the on-site outlet nozzle.
If necessary, pipes or special hot-air or foil hoses for air
distribution in the possible area of fan output (observe
the channel resistance/equipment compression).
◊ Use only hot air hoses (accessories) approved by
Remko. In the process, pay attention to the air direc-
tion!
◊ To prevent heat from building up, the pipes and
hoses may not have sharp kinks and bends.
◊ Counterpressure may not be allowed to build up
when using hoses to heat enclosed spaces.
If suction temperatures increase or if there is resistance
at the air output opening, the forced-air burner can
be switched off at short notice by the temperature
monitor (TW) during heating.
When the temperature falls, the burner restarts automatically.
◊ If the intervals are too short, the length of the hot air
pipes and hoses should be checked.

Commissioning of the
Forced-Air Oil Burner
The forced-air oil burner may be commissioned
only by expert personnel!
Preparation
Before starting with the adjustment of the forced-air oil
burner, perform the following tasks:
1. Remove the cover of the burner compartment.
2. Remove the fuel line from the burner and pull the
burner plug.
3. Unscrew the four quick-release fasteners of the
mounting base plate (1) at Position A.

To adjust the necessary distance, proceed as follows:
1. Loosen the knurled nut (10) and turn the adjusting
screw (7) accordingly.
Clockwise rotation: Distance A becomes
smaller
Counterclockwise rotation: Distance A be
comes larger
A

4. Carefully remove the complete mounting base plate
from the front of the unit.
5. Place the mounting base plate somewhere suitable
for the further tasks.
Required nozzle sizes
Selecting the required oil nozzle depends on the pump
pressure and the unit capacity. You may only use an oil
nozzle that is suitable for the shape of the respective
burner chamber with corresponding spray angle, cone
properties, and throughput. You can find the necessary
nozzle size in the technical data.

2. After adjusting the distance, retighten the adjusting
screw using the knurled nut (10).
The optimum setting must be adapted to the local conditions and the respective chimney.
Mounting base plate
After the ignition electrode, baffle plate, and air inlet
nozzle are adjusted, the mounting base plate is remounted.
1. Attach the mounting base plate using the four
quick-release fasteners.
2. Mount the fuel line to the burner.
3. Reinsert the burner plug.
All dimensions are approx.
Mount the baffle plate (D) in such a way that the hole
(E) is flush with the photo cell.

Adjusting the air inlet nozzle
1. Lock the adjust lever (3) of the air inlet nozzle in the
locking position (3) (see arrow).

Every stationary combustion plant must be check ´by
measuring the exhaust emission values according to
the first Bundesimmissionsschutzverordnung
(1.BImSchV) (German Air Pollution Act).
The owner is obliged to have the combustion plant
monitored by measurements performed by the local
chimney sweep up to four weeks after commissioning.
In addition, according to §§ 9 and 15 of 1. BImSchV, the
emission values must be checked annually by the local
chimney sweep (oil derivatives, soot, exhaust emissions).
Setting the pump pressure
For initial burner operation and after each time the
burner is serviced, the oil pressure must be adjusted or
Never operate the pump without oil!
1. Remove the stopper on the "P" measuring connection and mount the oil manometer (seal!).
2. Open all oil shut-off fittings. .
3. Switch on the burner using the operating switch.
4. Set the required oil pressure via the adjusting screw
(4) after loosening the counter nut (5).
Clockwise: Increase pressure
Counterclockwise: Reduce pressure
5. After making the pressure setting, secure the adjust-
ing screw using the counter nut (5).
Important information
◊
All specifications only serve as presettings and must
be readjusted or adapted according to the local conditions during the exhaust emission analysis. The
settings can be made only if the chimney has been
properly installed!
◊
On principle, the equipment must be operated at the
nominal load.
◊
To guarantee the optimum function of the burner,
please note that annual maintenance must be performed according to DIN 4755. For this purpose, you
should conclude a maintenance contract.

6. Switch on the unit using the operating switch.
7. Dismantle the oil manometer and replace the stop-
per (seal!).
Additional pump information
◊ Perfect fuel quality is absolutely necessary for the lu-
brication of the pump gear.
Never suction up water residue or fine dust that
tends to harden (such as cement).
◊ Never let the unit run with a dry pump for a longer
period of time.
