Fuel nozzle (Fig. 9a/9b)
The fuel nozzle (H) must be cleaned or replaced at
least once every heating season or more often if
necessary.
Clean the fuel nozzle from the front with compressed
air. To remove stubborn dirt, it can help to saturate
the fuel nozzle in clean fuel and wash it out. Take
care not to swap the two hoses (K / L).
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 distance 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
correctly positioned.
Fuel filter (Fig. 12)
Clean or replace the fuel filter (S) at least twice every
heating season or more often if necessary. The fuel
filter must be washed out with clean fuel.
Note: To undo the fuel filter, 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 optimum pump
pressure. Turning it clockwise will increase the
pressure, turning it counter-clockwise will decrease
the pressure.

display.
20
Possible cause
1. The pump pressure is not correct.
2. Soiled air filters.
3. Soiled fuel filter.
4. Soiled fuel nozzle.
5. Soiled photocell.
6. Photocell not fitted 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 filters.
3. Clean or replace the fuel filter.
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 flashes 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 filter.
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 filter.
5. Clean or replace the fuel nozzle.
6. Clean the tank, fill in fresh fuel.
7. Check all electrical connections.
8. Connect the ignition cable to the ignition
electrode.
9. Replace the ignition electrode.
