The Vitodens 200-W, WB2B boiler is equipped with the Lambda Pro Combustion
Management System developed by Viessmann which ensures optimal
combustion quality independent of gas quality and type. (For a description of the
Lambda Pro Combustion Management System, see page 27 in this manual.)
During initial start-up and maintenance you will only need to check the CO
O content at the boiler vent pipe adaptor.

boiler and create heat demand.
3. Set boiler to low-fire by pressing
buttons "9" and " " at the same
time. "Relay test" and then "Base
load" is shown on display.

2 2
boiler vent pipe adaptor. If the
measured values deviated by more
than 1% from the acceptable ranges
for the respective fuel type listed in
the right column or in the table on
page 27.
