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.

Please note:
The Vitodens 200-W, WB2B boiler, models WB2B 80 and 105, is for operation
with natural gas (for instructions on how to convert to operate with liquid
propane gas, see page 14). For high-altitude operation (above 5,000 ft. / 1,500
m), please see instructions on page 14. 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

boiler vent pipe adaptor. If the
measured values deviated by more
than 1% from the acceptable ranges
for respective fuel type listed in the
right column or in the table on page
27.
H check the venting system for leaks
(see subsection on page 18).
H check that the boiler is set for
the gas type used (see
subsection on page 13).
5. Enter measured values into the
Maintenance Record on page 73.
6. Set boiler to full-fire by pressing
"⊕". "Full load" is displayed.

and O
content at
