DANGER

Risk of electric shock

Touching the ignition device can lead to electric shock.

Do not touch ignition device during the ignition process.

Check tightness of oil carrying components.
Check function of:

ignition,
flame monitoring,
oil pump (pump pressure and suction resistance),
control and safety devices.

Check combustion values, if necessary re-adjust the burner.
Enter combustion values and settings in the commissioning record.
Refit cover.
