Description of Device
The unit is fired directly with heating oil EL or diesel and
can be operated with or without an exhaust-gas con-
nection. It is intended for mobile and fully automatic de-
ployment.
A fuel container is built under the unit and it is equipped
with automatic tank heating, a high-pressure atomizing
oil burner with optical flame monitoring, a low mainte-
nance axial ventilator, a connection cable with plug, a
room thermostat socket and a fourfold filter system.
The unit complies with the basic safety and health re-
quirements of the relevant EU stipulations and is reli-
able and simple to operate.
Working of Device
When the power plug is connected to a power socket,
the automatic tank heater is activated for temperatures
below 10 °C.
When the unit has been switched on or when heat is
required (automatic function with room thermostat) the
supply air fan starts. The fan blows air into and along
the combustion chamber.
When the preliminary ventilation is over, the electro-
magnetic valve opens and supplies fuel to the nozzle.
The fuel, sprayed under high pressure, is enriched by
an adequate quantity of oxygen according to the heat-
ing capacity and ignited by an electric spark. Once a
flame is burning, the automatic burner relay begins
monitoring the flame.
The automatic burner relay controls all unit functionality
fully automatically and monitors them for safety.
After a few seconds hot air is blown out.case of any
troubles, or if the flame is unstable or tends to go out,
the unit is switched off by the automatic burner relay.
The fault indicator warning lamp of the automatic burner
relay lights up. A restart cannot be made before the
manual release of the automatic burner relay.
When the unit has been switched off via the operating
switch or the room thermostat, the supply air fan contin-
ues running for some time to cool down the combustion
chamber and then it stops automatically.
Depending on the required heat rate the function de-
scribed above is repeated automatically in the case of
an operation with thermostat.
*For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C.
The unit can be used e.g. in the following areas:
- for drying new buildings;
- for point heating of outdoor workplaces;
- for point heating of workplaces in open, non fire-
hazard fabrication rooms and halls;
- for temporary heating of closed and open areas;
- for de-icing of machines, vehicles and non flammable
storage goods;
- for tempering frost-endangered parts.

as well.
1 2
Safety temperature limiter (STB)
The STB interrupts the supply of fuel if the unit over-
heats and causes the automatic burner relay to switch
off.
If the safety temperature limiter has triggered, the
cause of the disturbance must first be localised and
eliminated. Resetting via the "RESET" key is only possi-
ble after the sensor has cooled to below ca. 90 °C.
The safety temperature limiter is unlocked by pressing
the reset key.
Provision for Air Heaters
For the deployment of the unit, the relevant guidelines
must be observed
1. Operating personnel
1.1 The unit must only be operated by persons who
have been trained in its operation.
2. Installation
2.1 The unit must be installed so that it can stand in a
stable position.
2.2 The unit must be installed and operated in such a
way that the employees are not exposed to the
danger of exhaust gases and radiant heat and that
the occurrence of fires is ruled out.
2.3 The unit may only be installed and operated in
rooms if a quantity of air sufficient for the combus-
tion is supplied to the unit and the exhaust gases
are removed to the exterior.
A natural air supply sufficient for the combustion is
present if e.g.
The room contents in m² correspond with at
least 10 times the nominal heat load in kW of all
the units operating in the room and if windows
and doors ensure a natural change of air.
2.4 In deviation from point 2.3, the unit can be oper-
ated without an exhaust system in rooms if these
rooms have a sufficient air supply and are well
ventilated and if materials harmful to health do not
reach an unhealthy concentration.
2.5 A good natural air supply and ventilation is the
case if e. g.
The room contents in m² correspond with at least
30 times the nominal heat output of all units oper-
ating in the room and a natural change of air is en-
sured through windows and doors, or
openings which are not lockable are present in the
region of ceiling and floor for the air supply and for
out going air and the size of these openings in m²
corresponds with at least 0.003 times the nominal
heat output in kW of all units operating in the room.
2.6 The unit must not be installed or operated in rooms
and areas where the danger of fire or explosion ex-
ists.
3. Room drying
3.1 In deviation from point 2.3, in order to dry rooms
with an air supply sufficient for the combustion,
heating units can be operated without the exhaust
gases being removed to the exterior. In these
rooms, the permanent presence of persons is for-
bidden. Signs on the entrances to the rooms must
indicate that this is forbidden.
4. Examination
4.1 The unit must be tested by an expert as to its work
safety specific condition in accordance with the re-
quired deployment conditions but at least once an-
nually.
4.2 The exhaust values of the burner must be
checked.
5. Monitoring
5.1 When starting work, the persons commissioned
with the operation of the unit must check the unit
for obvious defects or deficiencies on the opera-
tional and safety mechanisms and check that the
safety mechanisms are present.
5.2 If defects or deficiencies are discovered, the super-
visor must be informed.
5.3 In the case of defects or deficiencies which en dan-
ger the operational safety of the unit, its operation
must be terminated.
6. Installation in closed, well aerated rooms with-
out connection to a chimney
6.1 The operation of the units is admissible when the
minimum air quantity needed for combustion and
mentioned in point 2.5 is supplied.
6.2 A safe exhaustion of the waste gases is to be en-
sured to exclude inadmissible pollution.
Fresh air is fed from below;
waste gases are exhausted towards the top.
7. Correct usage
7.1 The unit are to be used only for heating purpose in
industrial or commercial application because of their
construction and equipment.
7.2 If specification of the manufacturer or legal regula-
tions, are not followed or if unauthorised changes
are made on the unit, the manufacturer is not liable
for resulting damages.

6
*Avoid under or overpressure in the room where
the unit is installed, as this would result in com-
bustion troubles.
Installation Requirements
The heaters may only be installed in compliance with
the relevant regulations, in particular, regulations gov-
erning the installation and operation of fireplaces and
furnaces.
Any national/regional emission control laws or regula-
tions must also be observed.
Safety zones
◊ To ensure safe operation and guarantee unhindered
access to the unit for maintenance work, a safety
zone of 1.5 m should be maintained around the unit.
◊ Floors and ceilings must be fire-resistant.
Electrical Connection
◊ The units are operated with 230 V /1~ N / 50Hz.
◊ The unit must be connected to the power source at a
special terminal equipped with a switch to protect
against faulty currents.
Installation in closed, well aerated rooms without
connection to a chimney
◊ The units may only be operated when the minimum
amount of air required for combustion is supplied.
◊ A safe exhaustion of the waste gases is to be en-
sured to exclude inadmissible pollution.
- Fresh air is supplied from below.
- Waste gases are expelled upwards.
Outside installation
◊ Operation of the unit may not have any harmful ef-
fects or cause any unreasonable problems.
◊ The unit operator must ensure that unauthorised
persons are prevented from manipulating the unit or
its power supply.
◊ Because rain and snow can be sucked in by the air
supply fan, a suitable protective covering should be
used.
Heating Rooms
◊ Warm air generators may only be operated with a
room thermostat when heating rooms.
Accessories.
◊ Make sure that sufficient fresh air is fed to ensure
perfect combustion. Fresh air is to be fed preferably
through windows and doors or through sufficiently
dimensioned openings in the outer wall.
Malfunction-free operation is guaranteed if the exhaust
system is installed in an ascending direction and with
vertical end pipes.
The exhaust system must terminate at least above the
height of the eaves but better still above roof height in
order to avoid counter pressure caused by weather-
related circumstances (e.g. wind).
All exhaust-pipe parts must be attached reliably. Their
diameter must not be smaller than that of the exhaust
nozzle of the device (∅150 mm).
The minimum distance of 0.6 m to combustible parts
must not be exceeded.
Exhaust-pipe parts including attachment material are
available as accessories.
Exhaust system
In the outdoors or in open rooms, the operation of the
device is also possible without an exhaust system.
However, we recommend a 1 m exhaust-pipe (see ex-
ample 2) with a rain hood placed on top so as to rule
out the penetration by rainwater and dirt.
If the device is used for temporary room heating, the
combustion gases may have to be removed to the exte-
rior. The exhaust-pipe parts must be laid in such a way
that a minimum suction of 0.1 mbar is guaranteed.
*It must be made sure in all cases that counter
pressure due to an incorrect exhaust system is
ruled out.
Important hint.
Make sure that the waste gas pipes are correctly in-
stalled with a condensate trap (see example 1), to avoid
damage to the combustion chamber through humidity
deposits (condensate) (see example 3).
The lateral openings in the exhaust connection must
not be closed or covered.

Maintenance and Service
The unit is to be maintained regularly whereby some
fundamental rules are to be observed to ensure a long
service life and trouble-free operation.
After each heating period or even earlier, depending on
the deployment conditions, the entire unit including
combustion chamber and burner head must be cleaned
of soot sediments, dust and dirt.
The oil filters must also be cleaned / replaced at least
once a year or, depending on the degree of contamina-
tion of the fuel, frequently.
*Setting and maintenance is to be carried out
only by authorised personnel!
Adjusting the air slide plate
The air slide plate is set at the factory. The air through-
put may only be adjusted to local conditions by author-
ised personnel.

The measurement sensor is placed through the appro-
priate lateral secondary air opening in the exhaust con-
nection in the existing measurement opening in the pipe
nozzle of the combustion chamber (see drawing below).
*After maintenance work is complete, conduct an
electrical safety test.
Proper Use
The units are to be used only for heating purpose in in-
dustrial or commercial application because of their con-
struction and equipment.
The manufacturer is not liable for any damage resulting
from non-adherence to manufacturer specifications, le-
gal requirements or any modifications to the units.
Exhaust Measurement
On account of the construction-dependent design of the
exhaust connection (connection nozzle with secondary
air openings), it is not possible to perform a correct ex-
haust analysis in a conventional manner in the exhaust
pipe behind the exhaust connection.
For the performance of the exhaust analysis the sensor
of the exhaust-measurement device must be placed in
the centre of the pipe socket of the heat exchanger.
*
An operation/use other than indicated in these in-
structions is prohibited!
In the case of non-compliance, we assume no li-
ability and our guarantee becomes null and void.
Service and Guarantee
For the guarantee to be valid, the customer must com-
pletely fill out the “guarantee certificate” enclosed with
all heating units and send it back to REMKO GmbH &
Co. KG in a timely manner after purchasing of the unit
and putting it into operation.
The units have undergone several tests to ensure
proper functioning at the factory. If there are still mal-
functions that cannot be fixed by the operator using the
troubleshooting instructions, please contact your dealer
or contract partner.

Setting the pump pressure
The pump pressure can
only be set if a manometer
is connected to the connec-
tion P.
The pump pressure is
changed by turning the
pressure setting screw A.
Clockwise:
increase the pressure
counter clockwise:
reduce the pressure
The required pump pres-
sure is determined accord-
ing to the heating capacity
(please refer to unit type
plate) and to the nozzle size.
Wiring Diagram
Fuel Pump
The standard type of the pump runs in a system of
1 pipe. The required fuel is sucked in through the suction
line "S".
For the first starting and after having emptied the fuel
tank, the fuel system is deaerated through the burner
nozzle. For this purpose the unit is switched on. After a
possible switch off through failure, the unit is restarted
after having released the automatic burner relay (take
care of waiting time).
If, after the 3rd start of the unit there is another switch
off through faults, the fuel filters should be checked to
make sure that they are free from pollutions and that
they are tight.
