Trouble Shooting
CAUTION
Repair work on the electrical installation and on the burner may be carried out only by authorised, expert
personnel for safety-technical reasons.
Faults: Cause:
The supply air fan does not actuate. 2 – 3 – 4 – 6 – 7 – 8 – 25
The fan is running, but the burner does not ignite. 1 – 5 – 6 – 9 – 10 – 11 – 12 – 13 – 14 – 15 – 16 – 17
Das Gerät geht ohne Flammbildung auf Störung. 20 – 21 – 23 – 26
Das Gerät schaltet während des Betriebes aus. 4 – 5 – 6 – 7 – 8 – 9 – 10 – 11 – 13 – 15 – 16 – 17
(The pilot lamp on the automatic burner lights) 19 – 20 – 21 – 22 – 23 – 26
Formation of smoke during the unit is running 7 – 10 – 11 – 13 – 15 – 17 – 19 – 21 – 22
The appliance does not switch off in „0“ position. 18 – 25
Cause: Remedy:
1. Air bubbles in the fuel system during initial start up. Reset the fuel system by pushing the red pilot lamp.
Repead it 3 times if necessary.
2. The appliance does not have a voltage supply. Check the voltage supply and electrical connection.
3. No plug in the thermostat socket. Connect the thermostat or shunt plug with the thermostat socket.
4. The thermostat is set too low. Set the thermostat higher than room temperature.
5. The red pilot lamp of the burner relay is shining. Reset the burner relay by pushing the red pilot lamp.
6. Control relay fault. Change the control relay.
7. The motor is overloaded. Let the motor cool down.
(The fan is running irregularly or is blocked.) Check the fuel pump.
Check the electrical and mechanical functions of the motor.
8. The fuel pump is blocked. Check the fuel pump and exchange if necessary.
9. The fuel container is empty. Fill the container with clean fuel.
10. The oil filter is stopped up. Clean or exchange oil firter.
11. The nozzle is stopped up or has the wrong size. Exchange the nozzle (Pay attention to the right type and size).
12. The electrode is incorrectly adjusted, die isolation is defective. Adjust or exchange it.
13. The air inlet plate of the burner head is not correct or dirty. Adjust it with the CO
2
-Indicator and pump.
(CO
2
: 11 – 12 %, Bacharach: 0 – 1).
14. The solenoid valve does not open. Check the solenoid valve and exchange it if necessary.
15. The pump pressure is not correctly set. Adjust the pump pressur using a pressure gauge.
16. The pump coupling is defective. Exchange the pump coupling.
17. Leakage in the suction or in the fuel filter. Check and exchange if necessary.
18. The solenoid volve does not close. Temove the fuel line on the main filter. The flame extinguishes.
19. The protection grille of the supply air fan is dirty. Clean the protection grille.
20. The safety limiter (STB) switchs off. Check the air inlet grill and clean if necessary
and unlock the burner relay (only DZH 90 ).
21. Air bubbles in the fuel system. Start the appliance so that the air escapes through the nozzle.
Repead it 3 times if necessary.
22. Ventilation does not suffice. Open the door or windows.
23. The photoelectric cell is dirty or incorrectly adjusted. Clean the photoelectric cell or exchange it if defective.
25. The operation switch is without function. Check the operation switch and exchange it if necessary.
26. Paraffin formation in the fuel. Clean the fuel system; fill the contain with clean fuel.
