Troubleshooting
23. Troubleshooting
Observation Cause Remedy
Burner does not start
up
Oil not combustible due to sludge and / or water
Oil tank empty
Oil level in burner tank too high
Filter dirty, oil or air lines leaky
Faulty feed pump solenoid valve
Nozzle dirty or faulty
Feed pump blocked
No current
Motor faulty
Thermostat faulty
Photocell dirty or not correctly inserted
Control unit faulty
No ignition
No compressed air
Solenoid valve faulty
Compressor or air line faulty
Open the water drain cock on the burner tank,
drain off sludge and water or
use a higher-grade heating oil
Refill tank with oil
Correct the oil level by draining off oil by means
of the water cock (readjust the level control
float switch, if necessary)
Clean the filter, feed pump filter and lines
Check the feed pump solenoid valve and
replace if necessary
Replace nozzle
Strip the feed pump and clean the gear
Switch on the heater switch
Replace

Incorrect baffle plate setting
Combustion airflow rate too high or too low
Boiler room is not sufficiently ventilated
Correct the baffle plate setting dimensions
Set the primary airflow rate
Set the secondary airflow rate at the air control
flap
Pay attention to sufficiently large ventilation
