The combustions analisys shall be done using an analyzer regularly calibrated.
During normal operation the boiler performs combustion control cycles. In this phase, CO values higher than 1000 ppm can
occur for brief periods of time.

13.1 GAS CONVERSION METHODS
Only an Authorised Technical Assistance Service can convert boiler operation from
NATURAL GAS
to
LPG
or vice-versa. To
perform calibration, set parameter
P02
as described in the PARAMETER SETTINGS section. Lastly, check the combustion
parameters as described in the SPECIAL FUNCTIONS - CHECKING COMBUSTION PARAMETERS section.
When the gas change is completed the boiler data plate must be amended to indicate the new gas data.
