8.2.6 Checking the oil filter and cleaning the oil pump filter
• Check oil filter for contamination, replace if needed.
The oil pump filter is located under the oil pump cover (see fig. 6-4, page 42).
• Loosen screw (fig. 6-4, pos. 8) and remove oil pump lid.
• Remove oil pump filter and clean it.
• Insert new or cleaned oil pump filter.
• Check seal of oil pump cover and replace if needed.
• Put the pump lid in place and bolt it down.
8.2.7 Checking the burner
Checking the burner includes visually inspecting the burner's condition as well as making flue gas measurements.
Check:
• Open the combustion chamber Remove the burner only if the area of the combustion chamber is damaged.
• Clean the burner surface (cloth, plastic brush).
• Visual inspection of the fuel lines for clogging and denting.
• Check oil filter of the suction line, change the filter set if necessary.
• Clean the burner head at fuel exit in the area of baffle plate.
• If necessary, replace faulty parts.
• Close the combustion chamber.
• Start burner and with the "Control measurement" setting (see chapter 14) allow to run for approx. 10 min.
• Check combustion values:
– Flue gas temperature at measuring sockets of the flue gas pipe. (Target value < 120 °C),
– O
2
or CO
2
content (see section 6.3.1),
– CO content (target value < 50 ppm).
– Soot number according to Bacharach-Scale < 1.
Î
If the combustion values do not fall within the target range, the burner must be adjusted accordingly (see chapter 6.3).

To protect the oil pump and LE membrane valve, either insert the enclosed micro-replacement filter insert
MC-7
, (

for short filter cups or the
MC-18
, (

for long filter cups in the ventilation
oil filters. Only use filters of maximum 25 µm.
For more detailed information on checking and setting the burner, see chapter 6.3, on installation and removing
the burner, see chapter 6.4.
In the course of the maintenance activities, the automatic firing unit DKO 974 must also be rechecked to see
whether it attains the rated life cycle: 10 years or 250,000 burner starts,
We recommend completing the service log provided with all the measured values and the tasks performed with
date and signature.
