3.5. Oil pressure
We recommend setting the oil pressure between 9 - 14 bar,
see table on page 9 (see g. 19).
3.6. Final and safety tests
After completion of the exhaust gas measurements, the
system must be tested for proper and safe operation of the
controller and damper as well as of the automatic oil ring
system including safety time.
3.7. Chimney
The correct chimney cross-section provides the necessary
delivery pressure for proper functioning of the ring system
and discharge of the exhaust gases. For the function-related
chimney dimensions, the following original values must at
least be known:
• Design and rated heat output of the heater
• Exhaust gas ow of the heater
• Exhaust gas temperature at the outlet of the heater
• CO

content of the exhaust gas
• Required delivery pressure for supply air, heater and
connection piece
• Design and length of the connection piece
• Design of the chimney and eective chimney height
The design and version of the chimney are to be de-
termined according to DlN 4705 and DlN 18160.
