8.  FAULT LOCATION

8.1 

Burner will not start

Symptom

Motor starts 

Burner pre-ventilates

Flame formed

Burner trips

Motor starts 

Burner pre-ventilates

No lame formed

Burner trips

Causes

Unstable lame 

Excess air

Low oil pressure 

Incorrect combustion apparatus settings 

Flame monitor does not register light 

Defective lame monitor 

Defective oil burner control 

No oil 

False light 

No spark 

Remedies

Adjust the damper  

Check the oil pressure 

Check the nozzle in relation to the 

combustion apparatus dimensions and the 

ignition electrode position

Check the lame monitor is clean and can 

register light

Check with using new photocell 

Check using new oil burner control (Note: 

replacement of photocell recommended if oil 

burner control replaced)

Check the oil supply to the burner and that 

there are no air bubbles in the pump

Check function of solenoid 

Check lame monitor does not register 

ambient light 

Check high voltage wiring and ignition 

electrodes

Burner does not start

Burner pre-ventilates

Burner stops

Fuse blown 

Boiler thermostat has not reset 

Overheating protection has deployed

Defective preheater 

Defective oil burner control or  

lame monitor

No oil supply

Too great a pressure drop at brake plate 

Too strong draught prevents lame forming 

No spark 

Check and replace fuse as necessary. 

Investigate cause of fault 

Adjust thermostat 

Reset the overheating protection. 

Investigate the cause of its deploying.

Remedy fault

Check by replacing with new 

Check that tank, oil lines, solenoid valves, 

pump and nozzle are in good condition

Adjust the burner

Correct the boiler draught

Check the ignition transformer. Check the 

ignition electrode settings and ceramics

Burner pulsates at start with  

hot lue gases

Burner pulsates at start 

Too strong a draught

Too great a pressure drop at brake plate

Nozzle partially blocked

Oil pressure too low

Flue blocked or damaged

Fan wheel slipping on shaft

Pump coupling loose or worn

Preheater clogged

Delayed ignition

Too strong a draught

Too great a pressure drop at brake plate

Correct the boiler draught

Adjust the burner

Replace nozzle

Check and adjust

Check and correct

Check and tighten

Replace

Check ignition electrode adjustment 

(refer to technical data)

Check ignition electrodes  

not damaged

Check high voltage wiring

Check position of nozzle  

assembly adjustment

Correct the boiler draught

Adjust the burner

8.2 

Burner will not start after normal use

8.3 

Delayed ignition, burner starts; pulsation
