Legend for the items in Figure 9a/9b:
Item K = air hose (connection)
Item L = fuel hose (connection)
Item M = ignition cable
Item N = ignition electrode
Item P = burner head
Ignition electrode (Fig. 10)
The ignition electrode (N) must be cleaned or
replaced after every 600 hours in operation or
sooner if necessary. Clean the ignition contacts
(Q) carefully with a wire brush. Check the dis-
tance between the ignition contacts (Q). It must
be 3.5 mm.
Photocell (Fig. 11)
The photocell (R) must be cleaned or replaced at
least once every heating season or more often if
necessary. Clean the front of the photocell with a
cotton cloth which has been saturated in alcohol.
When you insert the photocell, make sure it is cor-
rectly positioned.
Fuel fi lter (Fig. 12)
Clean or replace the fuel fi lter (S) at least twice
every heating season or more often if necessary.
The fuel fi lter must be washed out with clean fuel.
Note: To undo the fuel fi lter, turn it 90° in counter-
clockwise direction.
Setting the pump pressure (Fig. 13)
The optimum pump pressure is quoted in the
technical data. While the equipment is working,
use a screwdriver to turn the setting screw (T)
until the pressure gauge (Item 8) indicates the op-
timum pump pressure. Turning it clockwise will in-
crease the pressure, turning it counter-clockwise
will decrease the pressure.
14. Troubleshooting information for
experts
Problem
The fl ame ignites but after a short while the
heater switches off , the LED fl ashes and "E1" ap-
pears in the display.
Possible cause
1. The pump pressure is not correct.
2. Soiled air fi lters.
3. Soiled fuel fi lter.
4. Soiled fuel nozzle.
5. Soiled photocell.

6. Photocell not fi tted correctly.
7. Photocell is defective.
8. Poor electrical connection between the pcb
and the photocell.
Remedy
1. Adjust the pump pressure.
2. Clean or replace the air fi lters.
3. Clean or replace the fuel fi lter.
4. Clean or replace the fuel nozzle.
5. Clean or replace the photocell.
6. Adjust the photocell correctly.
7. Replace the photocell.
8. Check the electrical connection between the
pcb and the photocell.
Problem
The heater does not work at all or the fan motor
runs for only a short while. The LED fl ashes and
"E1" appears in the display.
Possible cause
1. No fuel in the tank.
2. The pump pressure is not correct.
3. Corroded ignition electrode or wrong distance
between the ignition contacts.
4. Soiled fuel fi lter.
5. Soiled fuel nozzle.
6. Moisture / water in the fuel or fuel tank.
7. Poor electrical connection between the
transformer and the pcb.
8. Ignition cable is not connected to the ignition
electrode.
9. Ignition electrode is defective.
Remedy
1. Fill fuel into the tank.
2. Adjust the pump pressure.
3. Clean or replace the ignition electrode.
4. Clean or replace the fuel fi lter.
5. Clean or replace the fuel nozzle.
6. Clean the tank, fi ll in fresh fuel.
7. Check all electrical connections.
8. Connect the ignition cable to the ignition
electrode.
9. Replace the ignition electrode.
Problem
The fan motor does not switch on. The mains
voltage is active and the ON/OFF switch is set to
ON (I).
The LED is lit or fl ashes and "E1" or "E2" appears
in the display.
