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.

Installation instructions
The safety regulations
of the accident prevention
and insurance associations,
the respective regional building
regulations and the combustion
appliances regulations apply
in principle to the operation
of the unit.
■ Make sure that there is an
adequate fresh air supply
appropriate to the respective
forced-air burner capacity
(see name plate).
The forced-air oil burner
may need to be fitted with
a separate air supply for
combustion
Installation outside
■ The operation of the units
must not present a hazard or
unreasonable loading
■ The unit operator must ensure
that it is not possible for
unauthorised persons to be able
to manipulate either the unit
or the power supply.
■ The unit must be protected
from unauthorised use
■ Precipitation such as rain
or snow can be sucked
in through the supply air fan.
For this reason suitable weather
protection should be provided.
NOTE
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
■ The exhaust gases must be fed
to the outside via the flue gas
pipes.
Safety distances
■ In order to guarantee safe
operation and maintenance
of the units, 1.5 m safety
distance should be maintained
around the unit.
■ Flooring and ceilings must
be fire retardant
■ Intake and outlet diameters
must not be narrowed
or blocked with foreign objects.
Installation in closed, well
ventilated areas without
exhaust gas connection
■ The operation of the units
is permissible if the minimum
air quantity for combustion
is supplied.
■ Reliable extraction
of the combustion gases
must be guaranteed in all
cases in order to exclude
impermissible contamination
of the room air with hazardous
substances.
Fresh air is fed from below.
Exhaust gases are routed
upwards.
■ It is forbidden for personnel
to remain in these areas for
extended periods.
Appropriate prohibition
signs should be put up
at the entrances

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.
NOTE
Only "REMKO original
replacement parts"
must
be used when replacing safety
devices.
ATTENTION
Safety devices may be neither
bypassed nor disabled.
1. Unscrew protective cap [1].
2. Carefully press in the reset
button [2] with a suitable tool.
3. Screw the protective cap [1]
back on again.

Max. 1 metre
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
■ Ensure there is sufficient supply
of combustion air
■ Check that the inlet and outlet
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
if necessary by authorised
specialists.
NOTE
The hot air hoses must only
be used in fully extended form
and without any constrictions.
NOTE
Air feeds on the intake side
must always be implemented
by means of non-distorting
hoses/ducts (no unstable
hoses).
ATTENTION
If a build-up of heat should
occur then the heating
operation will be interrupted
by the STB permanently.
NOTE
Cycled operation
of the forced-air burner with
run times under 5 min. should
certainly be avoided.

s s s
Paraffin formation with low
outside temperatures
Even at low outside temperatures
it is necessary to ensure that there
is an adequate supply of heating
oil that is capable of flowing.
■ Paraffin formation can start
with temperatures as high
as 5 °C
■ To avoid this appropriate
preventative measures must
be implemented.
e.g. Winter-proof EL heating
oil or winter Diesel, heated oil
tank, insulated oil lines etc.
■ Note that fault-free operation
of the Multiflex oil pre-heating
can only be guaranteed
if the unit has been supplied
with electrical power for a long
period of time before starting
■ It is not possible to rectify
paraffin separation that
has already occurred with
the heating. If paraffin has
already formed it is necessary
to clean out the complete fuel
system
NOTE
The 400V version of the unit
is equipped with a device for
automatically checking the
turning direction of the fan
motor, as standard.
NOTE
The electrical connection
for the units must be made
at a separate feedpoint with
a residual current device
in accordance with VDE 0100,
Section 55.
ATTENTION
All cable extensions must only
be used in fully un-reeled
or reeled off condition.
NOTE
Paraffin formation can start
with temperatures as high
as 5 °C. To avoid this
appropriate preventative
measures must be
implemented, e.g. winter
Diesel.
