INFORMATION
For exact information regarding the checking and setting of
the burner, see
Chap. 7.3
.
For exact information regarding the assembly and disas-
sembly of the burner, see
Chap. 7.4
.
The scope of inspection includes:
1
Dismantling the burner (see
Chap. 7.4
).
2
Clean the burner surface (lapping, plastic brush) and check for
damage.
3
Visual inspection of the fuel lines for leaks, clogging and denting.
4
Check the oil filter, replace filter insert if necessary.
5
Clean the burner head at the fuel exit in the area of baffle plate.
INFORMATION
In the course of maintenance work, the safety relevant
components must also be inspected for the expiration of
their nominal service life:
▪ Firing unit: 10 years or 250,000 burner starts
6
If necessary, replace faulty parts.
7
Close the combustion chamber.
8
Put the burner into operation and let it run for about 10 minutes
in the "Emission measurement" position.
9
Check the combustion values:
–
Flue gas temperature at the measuring port of the flue gas
pipe (setpoint < 80 °C),
–
O2- or CO2-content (see
Chap. 7.3.1
),
–
CO content (setpoint < 100 ppm).
–
Soot number according to Bacharach Scale < 1.
If the combustion values do not lie within the set value range, the oil
nozzle must be replaced if necessary and the burner adjusted ac-
cordingly (see
Chap. 7.3.1
).
INFORMATION
We recommend entering all measured values and the work
performed with the date and signature in the enclosed op-
