The Vitodens 200, 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 29 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.

Please note!
The Vitodens 200-W, WB2B boiler, models WB2B 80 and 105, is for operation
with natural gas only. For high-altitude operation (above 5,000 ft. / 1,500 m),
please see instructions on page 17. The MatriX cylinder burner of this boiler is
preset for the entire gas group. No adjustment or readjustment of the burner is
required.
1. Connect a flue gas analyzer to test
port A at boiler vent pipe adaptor.
2. Open gas shut-off valve, start up
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.
4. Measure CO and O content at
2 2
boiler vent pipe adaptor. If the
measured values deviated by more
than 1% from the acceptable ranges
for natural gas listed in the right
column or in the table on page 29...
H check the venting system for leaks

subsection on page 16).
5. Enter measured values into the
Maintenance Record on page 74.
6. Set boiler to full-fire by pressing
"⊕". "Full load" is displayed.
7. Measure CO and O content at
2 2
boiler vent pipe adaptor. If the
measured values deviated by more
than 1% from the acceptable ranges
listed in the right column or in the
table on page 29...
H check the venting system for leaks
(see subsection on page 20).
