Locations at which units are
used
As mobile, directly fired fan-
assisted heaters, the units deliver
instant heat.
They are designed exclusively for
commercial use, with and without
warm air hoses.
The units may be used for the
heating, temperature adjustment
or drying of:
■ Warehouses
■ Exhibition halls
■ Trade fairs
■ Lightweight construction halls
■ Large tents / marquees
■ Large construction sites
■ Building drying
Unit description
The units are portable, directly
fired fan-assisted heaters (WLE)
with heat exchanger and exhaust
gas connections exclusively for
commercial applications.
The units are directly fired with EL
heating oil or Diesel fuel.
The units can be operated with
or without exhaust gas pipe
(depending on the conditions
on the customer's side).
They have been designed for
universal and straightforward use.
The units must be exclusively
operated with separate type-
approved forced-air WLE-type
burners.
The units are equipped with
a noise-optimised and low-
maintenance, high performance
radial fan, a room thermostat
receptacle and a mains cable with
a 230 V shock-proof plug or CLK
170-RV with 400 V CEE connector.
The CLK 170-RV units are
equipped with a device for
automatically checking the
turning direction of the fan motor,
as standard.
With factory fitted forced-air oil
burners the CLK 170-RV units
have integrated REMKO Multiflex
oil pre-heating fitted as standard.
With the CLK 80-RV this
is available as an option
(EDP no. 1071411) .
The units conform
to the fundamental health
and safety requirements
of the appropriate EU stipulations
and are simple to operate.
Operating sequence
If the units are set to heating
mode, then the forced-air burner
starts automatically. In fully
automatic heating mode with
room thermostat the forced-air
burner starts only when heat
is required.
After the burner has run for a short
time the temperature controller
"TR" (target temperature
ca. 40°C) switches the supply air
fan on automatically.
Warm air is blown out.
When operating with a room
thermostat this process is
repeated automatically depending
on the heat demand.
The temperature monitor "TW"
(target temperature 80 to 85°C)
monitors the internal temperature
of the unit.
After switching off the units via
the operating switch or the room
thermostats the supply air fan runs
to cool the combustion chamber
with the heat exchanger for
a certain time and then switches
off automatically.
This process may be repeated
several times if necessary,
depending on the temperature
profile.
In simple ventilating mode the
unit can be used to recirculate the
air permanently.
Thermostatic control is not possible
in this case.

Overpressure and
underpressure in the
installation area should be
avoided as this will inevitably
lead to combustion-related
faults.
ATTENTION
The units must only be
installed in well ventilated
spaces and not in living areas
or similar recreational areas.
Room heating
■ The units may only be operated
for room heating with a room
thermostat (accessory)
■ The fresh air supply required for
trouble-free combustion must
be guaranteed.
It is practical to have the fresh
air supply provided by
windows and doors or through
appropriately dimensioned
openings in the outside wall

Safety equipment
The units have the following
control or safety equipment:
Temperature controller (TR)
The temperature controller
controls the switching on and off
of the recirculating fan. The switch
point is set via the "Scale 21 - 60°"
controller in the switching cabinet.
Target value ca. 35 - 40 °C.
Temperature monitor (TW)
The temperature monitor limits
the unit or outlet temperature
in heating mode via the burner.
The switch point is set via
the "Scale 34 - 110°" controller
in the switching cabinet.
Target value ca. 80 - 85 °C.
Safety temperature limiter (STB)
The unit is permanently switched
off by the safety temperature
limiter (STB) in the event
of the unit overheating
or a temperature monitor
malfunction.
Manual resetting is required.
Automatic burner
The unit is permanently
switched off by the automatic
burner through the optical
flame monitoring in the event
of irregularities in the combustion,
the flame extinguishing, fuel
deficiencies etc.
Manual resetting is required.
Regulating device
The temperature sensor
of the controller is self-monitoring.
The probes are cold-resistant
to -25 °C.
At temperatures below -25 °C
the controller current flow will
be interrupted - if the temperature
rises above -25 °C the current flow
will be released again.
In the event of the probe
or the capillary tube being
damaged, as well as if an
overtemperature of ca. 220 °C
is reached, the fill medium will
be emptied and the safety device
is permanently triggered.
Resetting is no longer possible.
The controller is no longer fully
functional and must be replaced.
Safety temperature limiter
(STB)
The heating function
is permanently interrupted
by the safety temperature limiter
(STB) in the event of the units
overheating or malfunctioning.
Manually resetting of the STB
can only be implemented after
the units have cooled down.
The resetting of the STB
is implemented by actuating
the reset button 2.
12
ATTENTION
If the safety temperature
limiter has been tripped then
the cause of the malfunction
should be identified and
rectified before resetting it.
NOTE
In order to prevent a renewed
exceedance of the triggering
temperature the operating
conditions of the unit should
be checked before resetting
the STB.

In order to avoid the combustion
chamber being damaged due
to condensation of moisture
(condensate) in example 3,
make sure that the exhaust gas
ducting is correctly installed
with a condensate trap as shown
in example 1.
Exhaust ducting
■ Fault-free operation
is guaranteed if the exhaust
gas routing is fitted in a rising
arrangement and with a vertical
end pipe
■ The exhaust gas routing should
end at least above the height
of the eaves but ideally above
the height of the ridge, in order
to prevent any counter-pressure
being caused by poor weather
conditions (e.g. wind)
■ The minimum distance of 0.6 m
to combustible parts must not
be infringed
■ Exhaust gas ducting parts
and fastening materials are
available as accessories
It is also possible to operate
the units outside or in open
rooms / halls without exhaust gas
routing.
However, we recommend fitting
a 1m exhaust gas duct with a rain
hood on top (example 2), in order
to exclude the ingress of rainwater
and dirt.
If the units are used for room
heating then the combustion
gases must be routed away,
to the outside if necessary.
■ The exhaust gas routing must
be designed such that the
thermal lift of the exhaust gases
is guaranteed at all times
■ Die The exhaust gas routing
must be designed such that
there can be no counter-
pressure
■ All parts of the exhaust gas
routing must be reliably
fastened. Its diameter must
not be smaller than the outlet
nozzle of the unit.
Notes for implementing the 1st.
BImSchV
Units that are not expected
to be operated for longer than 3
months in the same location are
not subject to any approvals or
monitoring per the 1st. BImSchV.
(§1, section 3)
✔
NOTE
After installing an exhaust
gas system the settings
on the burner should
be adapted to suit the new
conditions.
ATTENTION
There must be no counter
pressure arising from incorrect
installation of exhaust
gas ducting under any
circumstances.

Air distribution
The units are equipped with a high
performance radial fan, which
has been designed to transport
the heated air efficiently
and effectively over large
distances.
The distribution of the air
is preferably implemented via
ducting or special warm air
or membrane hoses.
■ Use hot air hoses approved
by us (accessories) exclusively
■ Observe the air flow direction
of the hoses with this!
The inner overlapping
on the seams of the hot
air hoses must point
in the direction of the air flow.
■ Make sure that the hose
or ducting is securely fastened
onto the unit outlet nozzle
and any connection pieces that
may be being used
■ Only suitable air distributors
or air distributors approved
by ourselves should be used for
the air distribution
■ Enclosed spaces being heated
via hoses must not present any
overpressure
■ The forced-air burner can
be switched off briefly during
operation by the temperature
monitor (TW) in the event
of there being increased intake
temperatures or resistance
at the unit's outlet.
After the temperature drops
again the burner starts anew
automatically!
■ If the cycle intervals are too
short the length and layout
of the hot air routing should
be checked
■ There should be no kinks
or bends in the layout of the
hoses in order to prevent hot-
spots forming.
Membrane hoses must not be
twisted
Suction air
Fresh air, mixed air or
circulated air operating modes
can be selected on the unit.
The following information refers
to the installation of the unit
outside the space to be heated.
Fresh air operation:
The air intake is implemented
in the factory through 2 intake
grills, right / left.
Mixed air operation:
For operation of the unit in mixed
air mode it is necessary to fit
the intake nozzles, available
as accessories.
In order to guarantee adequate air
throughput the second intake grill
must not be covered.
Circulated air operation:
For operation of the unit
with 100% recirculated air
it is necessary to fit two intake
nozzles, available as accessories,
in place of the 2 factory-fitted
intake grills.
Before commissioning
The units should be checked for
visible defects on the operating
and safety devices as well
as proper installation and correct
electrical connections before
commissioning.
It is essential that the following
points be observed:
■ The units must be installed
in a stable position

are free
■ Prevent overpressure
or underpressure
in the installation area
■ Ensure that there is sufficient
fuel supply and that it complies
with the respective local
regulations
■ Only use clean EL heating oil or
Diesel fuel. Do not use Bio-
Diesel!
■ The suction pipe in the base
of the tank must be fitted with
a foot valve as a matter of
principle
NOTE
After fulfilling the respective
local regulations as well
as a professional installation
of the unit, the exhaust values
for the forced-air burner must
be checked and adjusted

7. Before an STB reset ensure that
the causes have been analysed
and rectified.
The following causes are
possible:
- The units were not able to cool
down because the electrical
connection was interrupted.
- Too high an outlet temperature
due to incorrectly implemented
air routing when operating with
hoses.
- Air inlets or outlets are not free
or are inadequate.
8. Check whether the "Burner
fault" indicator light on
the control panel is illuminated.
If this is the case, then reset
the automatic burner.
Troubleshooting
9. Move the operating switch
to the "II" (Ventilate) position.
If the supply air fan now starts
up the fault may well be in the
burner area.
Forced-air burner and power
supply
1. Check the oil filter(s) for
contamination. Replace
contaminated oil filter(s).
2. Check whether the shut-off
cock on the oil filter is open.
3. Check the fuel tank for
sufficient fuel level.
4. Check the heating oil for
paraffin separation.
Possible from 5 °C!
5. Check the oil hoses for damage.
6. Check the safety devices'
capillary tubes and probes for
damage or contamination.
7. Use appropriate means to check
that the temperature monitor
(TW) is functioning properly.
8. Check the forced-air burner for
possible damage to the nozzles,
baffle plate, filter etc.
The supply air fan does not
start
1. Check the fan can move freely.
2. Check the controller fuse in the
switching cabinet.
3. Check whether the motor
protection switch in the
switching cabinet has tripped.
4. Use appropriate means to check
that the temperature controller
(TR) is functioning properly.

After loosening the 4 fastening
bolts the mounting baseplate M
is pulled off the housing G.
From size SL 44, 6 fastening screws
must be removed (note marking
arrows).
The most important functional
parts for the installation /
maintenance are now immediately
accessible, as per the respective
requirements.
For maintenance work or for
installing / replacing the oil
nozzle, the mounting baseplate
M can be positioned on the
burner housing G in 2 ways (see
figs. 1 and 2).
The baseplate can be positioned
in the desired / possible position
on the special mounting points
in accordance with the unit-
specific options.
Commissioning the forced-air oil burner
Mounting baseplate
After having replaced the nozzle
and carried out any adjustments
required to the air inlet nozzle A,
the mounting baseplate M is re-
fitted in reverse order.
Adjusting the ignition electrode and baffle plate
All sizes are approximate values
and are in mm. The optimum
setting must be adapted to
the unit-specific and structural
conditions.

Required nozzle size
The selection of the required oil
nozzle is dependent on the pump
pressure and the unit capacity.
Only a nozzle that is approved
for the respective combustion
chamber geometry with
corresponding spray angle
and cone characteristics may
be used.
Refer to the technical data for
the required oil nozzle size.
Air inlet nozzle
The required blower pressure can
be adjusted with the adjustable air
inlet nozzle A in accordance with
the combustion chamber resistance
and chimney draft, without having
to change the output diameter.
1. Loosen the Allen screw B.
2. Turn the air inlet nozzle A
to the desired position (note
arrows!).
"min" = Smaller blower pressure
"max" = Larger blower pressure
Preparatory tasks
NOTE
Because the air flap, up to size
44, is sprung this should
be closed beforehand with
the help of the adjustment
screw [3] (turn adjusting screw
approx. as far as scale value 1).
ATTENTION
The commissioning
of the forced-air oil burner
may only be carried out
by trained specialists.
