Operating sequence
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. This process may be repeated
several times.
Monitoring of the unit
The safety devices of the devices
and the burner control unit
(component of the blower burner)
are used to perform all functions of
the units fully automatically and to
monitor their safety.
In the event of malfunctions or
if the flame is extinguished, the
automatic burner switches the
units off.
The indicator lights on the control
panel and the burner lamp on the
burner control unit light up.
Before restarting the device,
the automatic burner must be
manually released. To do this, press
the external reset button on the
control panel or the reset button
on the automatic burner unit.
The temperature controller (TR)
controls fan operation.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU stipulations, and are simple to
operate.
CAUTION
The units may never be
disconnected from the mains
prior to the completion of
the follow-up cooling phase
(except in emergencies).
If the units are set to heating
mode, then the forced-air burner
starts automatically.
After the burner has run for a short
time the temperature controller
"TR" 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
heating requirement.
The temperature monitor "TW"
monitors the internal temperature
of the unit.
The temperature monitor (TW)
limits or regulates the device
temperature during heating
operation.
The safety temperature limiter
(STB) interrupts the heating
function in case of extreme
overheating or a failure or
malfunction of the TW.
The STB can only be manually
reset after the units have cooled
down.

Exhaust gas ducting
It is also possible to operate the
units outdoors or in open spaces
without exhaust ducting.
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 ducting must
be designed so that the thermal
lift of the exhaust gases is
guaranteed at all times
■
The exhaust gas ducting must
be designed so that no counterpressure can be generated
■
Fault-free operation is
guaranteed if the exhaust gas
ducting 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 be
met
■
Exhaust gas ducting parts and
fastening materials are available
as accessories
■
All parts of the exhaust gas
ducting must be reliably
fastened Its diameter must
not be smaller than the outlet
nozzle of the unit

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
from temperatures below 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
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.
Air distribution
The units are equipped with a
high performance axial fan. This
fan is designed to specifically and
effectively transport the heated air.
The distribution of the air is
preferably implemented via
ducting or special warm air or
membrane hoses.
The possible lengths depend on
the air-side resistances of the air
ducts used.
■
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 to
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
NOTE
The burner setting must be
checked after every change of
location and adapted to the
new environmental conditions
and atmospheric conditions if
necessary.
NOTE
The hot air hoses must only
be used in fully extended form
and without any constrictions.
10
Commissioning
■
There should be no kinks or
bends in the hose lines in order
to prevent hot-spots forming.
Membrane hoses must not be
twisted
■
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
increased intake temperatures
or resistance at the unit's outlet.
After the temperature drops
again the burner restarts
automatically!
NOTE
Cycled operation of the
forced-air burner with run
times under 5 min. must in any
event be avoided.
■
If the cycle intervals are too
short the length and layout of
the hot air ducting should be

Troubleshooting
!
CAUTION
Before undertaking any work
on the units, the power plug
must be removed from the
mains socket.
The unit does not start
1. Check power supply.
2. Move the operating switch to
the "I" (Heating) position.
3. Check whether the
"Operation" indicator light on
the control panel is illuminated.
It must light up in the
"Heating" mode.
NOTE
The indicator light only indicates
the "Heating" mode. There is
no display in the "Ventilate"
operating mode or with the room
thermostat switched off and
when the STB has been triggered.
4. Check the strapping connector
or the room thermostat plug,
if fitted, is seated properly and
making good contact.
5. Check the setting of the room
thermostat.
The temperature set must be
higher than the current room
temperature.
6. Check whether the safety
temperature limiter (STB) has
tripped.
To do so, remove the protective
cap next to the control panel.
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 ducting 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.
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 even 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.
!
CAUTION
If the burner should carry out
a fault shut-down once again
after the start phase, then
another reset should be carried
out after a waiting period of 5
minutes has passed.
Further reset procedures must
be prohibited as there is a
danger of deflagration.
The supply air fan does not
start
1. Check the fan can move freely.
2. Check the electrical cables on
the supply air fan for damage.
3. Check the operating condenser
of the fan.
It is located in the unit's
switching cabinet.
4. Use appropriate means to check
that the temperature controller
(TR) is functioning properly.

Commissioning of forced-air oil burners
Preparatory tasks
!
CAUTION
The commissioning of the
forced-air oil burner may
only be carried out by trained
specialists.
After loosening the 4 fastening
bolts the mounting baseplate M is
pulled off the housing G.
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).
The most important functional
parts for the installation/
maintenance are now immediately
accessible, as per the respective
requirements.
From size SL 44, 6 fastening screws
must be removed (note marking
arrows).

Required nozzle sizes
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.
All sizes are approximate values and
are in mm. The optimum setting
must be adapted to the unitspecific and structural conditions.
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
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.

the unit capacity and the further
burner settings.
Adjustment of the air flap
Adjust the air flap as follows:
1. Loosen the knurled nut 4.
2. Set the adjusting screw 3
accordingly.
Turn to the right = Less air
Turn to the left = More air
4. After having set the adjusting
screw 3 lock it again with the
knurled knob 4.
NOTE
Never let the pump run for
extended periods without any
fuel. Never leave the units for
extended periods with a pump
that has run dry.
Adjust the pump pressure as
follows:
1. Remove the stopper on the
measurement nozzle "P".
2. Fit a suitable oil pressure
manometer here.
3. Open all oil shut-off devices.
4. Switch on the burner.
5. Set the required oil pressure in
accordance with the nozzle size
and the unit capacity.
6. Switch off the burner after
completing the adjustments.
7. Remove the oil pressure
manometer again.
Re-fit stopper incl. seal.

Additional notes
■
If the flame should give off
sooty smoke or break away
with a fully opened air flap,
reduce the pressure behind the
baffle plate with the help of the
secondary air setting
■
It may also be necessary to
open the air inlet nozzle further
!
CAUTION
If the burner should carry out
a fault shut-down once again
after the start phase, then
another reset should be carried
out after a waiting period of 5
minutes has passed.
Further reset procedures must
be prohibited as there is a
danger of deflagration.
All values provided are only preliminary settings and must be adapted or calibrated in accordance with the exhaust gas analysis.
