Standard values for burner adjustment

Notes regarding burner settings for room sealed operation

The burner must be adjusted with all associated pipes
adapted and connected (e.g. ventilation air, flue gas).
If using room sealed or coaxial ventilation air and flue systems
To adjust the burner settings, the boiler water tempera-
ture must be at least 60 °C.
If using separate or parallel ventilation air and flue systems
If, at the time when burner settings are made, the out-
side air temperature is not +15 °C, we recommend
adjusting the CO value by regulating the air volume in

accordance with the following table. For the adjust-
ment procedure, see chapter "Adjusting the air vol-
ume"; standard values for air damper and blast tube
connection settings can vary slightly on account of
geodetic height, air pressure and temperature.

Once it has been adjusted, no further pipes may be
connected and existing pipes may not be removed or
altered.
When making the adjustments, also take account of
the average local air pressure.
