Delayed Ignition; Noise In Pump - Bentone B 30 A2.2 RME Installation And Maintenance Instruction

9.3 Delayed ignition

Symptom
Burner pulsates at
start with hot flue gases
Burner pulsates at start

9.4 Noise in pump

Symptom
The burner pump emits noise during start
The burner pump emits noise during
operation
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
Causes
Insufficient negative pressure on the
suction side pump
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

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.
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
