10.3 Delayed ignition
Indications
Burner pulsates at
start with hot flue gases
Burner pulsates at start
Causes
Excessively strong draught
Excessive pressure drop across the brake
plate
Preheater temperature too low
New oil type
Nozzle partially blocked
Oil pressure too low
Flue is blocked or damaged
The fan wheel is slipping on the shaft
Pump coupling loose or worn
Preheater blocked
Delayed ignition
Excessively strong draught
Excessive pressure drop across the brake
plate
Preheater temperature too low
New oil type
Remedies
Correct boiler draught
Adjust the burner
Check preheater function
Adjust the preheater's set operating
temperature
Ensure that the new oil's physical parame-
ters are within the limits for which the
burner is designed. If not, change the oil.
Replace nozzle
Check and adjust
Check and correct
Check and tighten
Replace
Check the ignition electrode setting,
(see technical data)
Check that the ignition electrodes
are not damaged
Check high voltage cables
Check position of
nozzle assembly setting
Correct boiler draught
Adjust the burner
Check preheater function
Adjust the preheater's set operating
temperature
Ensure that the new oil's physical parame-
ters are within the limits for which the
burner is designed. If not, change the oil.
Indications
The burner pump emits noise during start
The burner pump emits noise during
operation
10.4 Noise in pump
Causes
Insufficient negative pressure on the suction
side pump
Remedies
Check the oil system in order to reduce
pressure drop
Rebuild the oil system to form a solution
with a transport oil pump
Check that the oil used has the physical
parameters that the burner is rated for. If
not, change the oil.
Temperature of the oil from the tank is too
low, increase the temperature of oil from
tank
Clean the pump filter
10.5 Pump pressure
Indications
The burner pump can not build up pressure
Causes
No oil
Oil viscosity too low
Pump worn
Pump run using impure oil that has worn the
pump out prematurely
Blocked pump filter
Remedies
Check that there is oil and that it reaches
the pump
Check that the oil reaching the pump has
the physical parameters that the pump
can handle. Change the oil or the pump's
oil parameters
Replace the pump
Replace pump and install self-cleaning
filter in the oil system
Check, clean pump filter
