Start-up and Maintenance
The Vitodens 100-W boiler is factory
preset for operation with natural gas. It
is recommended that a CO
2
check be
performed at the boiler vent pipe
adaptor as part of the initial
start-up/maintenance procedure.
The cylinder burner of the Vitodens
100-W is preset. No adjustment or
readjustment of the burner is required.
The CO
2
value lies within the range of
H 6.6 to 10.0% for natural gas
The CO
2
value measured must be
compared with the above CO
2
value.
Note:
If step 7 above is not performed, the
process will end automatically after 30
minutes.
If the CO
2
value measured lies more
than 1% outside the stated range,
