5. Burner servicing
5.1 Servicing
Servicing must be carried out after 3,000 operating hours, but at least once
yearly.
Only authorised personnel may perform service.
Before any type of servicing is carried out, shut of the power at the main
switch and turn off the oil.
Be careful: certain parts exposed after separation of the burner can be hotter
than 60°C. Care should be taken by the installer to ensure that electrical
cables and oil lines are not pinched or otherwise damaged during installation
or servicing.

During servicing, the burner can be hung from the screw in the burner fl ange.
This makes the burner pipe, brake plate, preheater and electrodes easily
accessible.
