Prior to starting, the unit is to be checked to make sure
that there are no visible defects on the control and
safety devices, that the unit has been installed correctly
and that it has been properly connected to the mains.
Installation requirements
à Install unit in a stable position.
à Make sure that air is supplied for combustion.
à Make sure that the air can be sucked in and be ex-
hausted freely.
à Avoid overpressure and underpressure in the room
where the unit has been installed.
à The waste gas values of the burner are to be
checked and adjusted properly by authorised experts
in accordance with the local conditions.
Power supply
à Any additional clauses of the relevant building regu-
lations and technical rules for combustible liquids
(TRBF 210 and 280) are to be observed.
à Only use clean fuel oil EL and diesel, respectively.
à Make sure that enough fuel is supplied.
à A sufficient quantity of free-flowing fuel oil must be
available even with low outside temperatures.
Paraffine formation can start even at a temperature
of 5° C. Adequate measures are to be taken to
G
avoid this.
à Connecting cable extensions may be laid exclusively
by authorised electricians based on the unit capacity,
cable length and taking the local terms of use into
account.
à The connection to the mains of the units is to be car-
ried out in accordance with the VDE 0100 regula-
tions to a special supply point with protection device
against faulty current.
Hot air distribution
The unit is equipped with a high-duty radial fan. It is suit-
able for selective and effective transportation of
warmed-up air for long distances.
Air is preferably distributed through pipings or special
hot air and sheet hoses, respectively. Hot air may be
distributed only in accordance with the fan capacity of
the units concerned.
The possible hose/pipe lengths depend on the resis-
tance on the air side of the used air ducts.
Please observe the following instructions when hot air
hoses are to be fitted:
à Please use exclusively those hot air hoses
(accessories) which have been approved by our
company.
à The inside overlappings on the seams of the hot air
hoses must run with the air current direction.
à Make sure that the hoses and pipes, respectively,
are safely fastened to the unit’s outgoing air connec-
tion piece.
à The pipes and hoses may not have sharp kinks and
bends in order to avoid heat accumulation.
à In the case of increased suction temperatures or re-
sistance on the unit’s outgoing air side, the burner
can be switched off by the temperature controller
(TW) during the heating operation for a short time.
à When the temperature has fallen the burner is re-
started automatically.
While the unit is operating, frequent startings of
G
the burner should be avoided.
When the temperature is too high on the unit’s out-
going air side, the heating-operation is interrupted
G
automatically for a longer period by the STB!

Oil Burner
After releasing 6 screws (pay attention to arrows); the
burner baseplate can be removed from the case and
hooked in laterally. (HTL 150-FB only 4 screws)
All operating parts are immediately accessible and can
be serviced without any difficulty.
To service the mixing head as well as to fit and replace
the nozzle, hook baseplate in horizontally.
1. Hold baseplate horizontally.
2. Push right-hand mounting laterally into hook device.
3. Hook left-hand side into the lug.
Air inlet device
By means of the adjustable air inlet device, the neces-
sary burner-pressure can be adjusted, according to re-
sistance of combustion chamber and chimney draught ,
without changing the starting cross-section.
Loosen socket screw and turn
air inlet device into desired posi-
tion (pay attention to the arrows!).
Turn to „min” = reduced burner-
pressure
Turn to „max” = increased
burner-pressure
After changing the nozzle and setting the air inlet de-
vice, baseplate must be mounted in reverse order.

counterclockwise rotation (+) = higher scale values
ð reduced pressure behind the device
ð upper performance range.
Clockwise rotation (-) = lower scale values
ð increased pressure behind the device
ð lower performance range.
Setting the pump pressure
When starting the burner and after every service, the oil
pressure must be set and/or checked.
Never operate the pump without fuel!
1. Remove plug from connection „P” and mount a ma-
nometer.
Pay attention to an appropriate sealing.
2. Open all stop valves and switch on the burner.
3. Set oil pressure according to nozzle size and re-
quired heating performance.
It is advisable to set required pressure DV2 (stage 2)
first and then DV1 (stage 1), because adjustment
DV2 can also effect DV1.
4. Switch off the burner.
5. Disassemble manometer and insert plug again.
Pay attention to the sealing.
All measures are approx. values in mm. The optimal setting
must be adapted to local and structural circumstances.

Operate the burner exclusively in 2nd stage. The
first stage may only be used as a starting-relief.

Servomotor LKS 130-2
The servomotor has three switch-functions as well as a
switch contact for the solenoid valve stage 2.

1. Closed air throttle
If the burner is not in operation
the servomotor is in position
-
„closed air throttle“ (scale: 0).
This position is fixed by the
manufacturer and may not be
changed.
2. Air volume „stage 1“
For preheating, start and opera-

tion with „low“ output the servo-
motor rotates to the switch con-
-
tact of the blue cam.
By means of this you get a fixed
opening angle for the air throttle
and a constant air volume for the
first stage.
For a different air volume you
can regulate with this lever the

air volume „stage 1“;
standard value: approx. 30°.
3. Tripping point „solenoid 2“
Place the black lever (solenoid 2)
approx. 1/3 of way between the
blue and the orange lever.
4. Air volume „stage 2“
When the burner gets the clear-
4)
ance for the second stage, the
servo motor rotates up to the trip-
ping point of the orange cam.
During its rotation the black lever
releases the oil-quantity for the
second stage;
standard value: approx. 50°.
Setting the air throttle
The air throttle is opened or shut until the soot has an oil
free colour, soot „0-1“ and CO
-value is 12-14%. When

setting, note that if there is a considerable excess of air,
the soot value can increase and oil can also appear in
the soot. If the flame becomes sooty or burns away
from the nozzle when the air throttle is fully open, re-
duce the pressure behind the device by means of the
setting screw.
Setting „air volume stage 1“
(adjustment lever blue)
Disconnect the 4-pole multi-plug-connector (thermostat
stage 2 ). Move the adjustment lever „air volume stage 2“
orange and the adjustment lever „solenoid valve 2“ black
clockwise until the two control cams are not pressed in or-
der not to impede the setting of the control cam „air vol-
ume 1
Less air „stage 1“:
Set the blue adjustment lever by moving it anticlockwise to
decrease the opening angle. If the burner is operating, the
servomotor turns automatically.
More air - „stage 1“:
Set the blue adjustment lever by moving it anticlockwise to
decrease the opening angle. If the burner is operating, the
servomotor turns automatically.
Switch point „solenoid valve 2“
(lever black)
Now move back the adjustment lever for „solenoid valve 2”
anticlockwise and the switch point „air volume stage 2“ is
set just behind the switch point „air volume stage 1“ This
switch point will operate between the settings „air volume
stage 1“ and „air volume stage 2“ .
Please check that under no circumstances the control
cam of „solenoid valve 2“ is activated before the con-
trol cam „air volume stage 1“, because this would
mean that „solenoid valve 2“ opens in the range of „air
volume 1“ and the burner would operate with exces-
sive deficiency of air.
Setting air volume „stage 2“
(adjustment lever orange)
The adjustment lever for „air volume stage 2“ is now
turned back anticlockwise and the switch point for „air vol-
ume stage 2“ is determined according to the burner output
behind the switch point „solenoid valve 2“. Reconnect the
4-pole multi- plug-connector „thermostat stage 2“. The ser-
vomotor moves via „solenoid valve stage 2“ to position „air
volume stage 2“.
Less air „stage 2“:
Move the orange adjustment lever anticlockwise to a
smaller opening angle. Switch the burner briefly back to
stage 1. When stage 2 is switched on again, the servo mo-
tor turns to the adjusted volume of air.
More air „stage 2“:
Move the orange adjustment lever clockwise to a larger
opening angle. In stage 2 operation the servomotor turns
automatically.
Check that neither the servomotor nor the air throt-
tle make mechanical contact to any point, because
G
this could damage the motor!
