Setting the CO
2
value and pump pressure
During commissioning and after regular maintenance work, the CO
2
value must be set. Set the CO
2
value according to
the information on the burner at a boiler temperature of at least 60 °C.
For two-stage burners, both stages must be set.
To set the poop pressure, insert a pressure gauge into the measuring connection (P). Only use a sealing ring to seal
the pressure measuring connection. Do not use Teflon tape.
With the two-stage oil pumps, the pressure of the first and second burner stage is set separately on the oil pump via
the respective adjusting screws.
