Maintenance
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics
intact, especially: the flue gas temperature and combustion
chamber pressure.
Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Flame inspection window
Clean the glass of the flame inspection window.
7.2.4 Combustion control (gas)
Carry out an analysis of the combustion flue gases.
Significant differences with respect to the previous
measurements indicate the points where most care should be
exercised during maintenance.
If the combustion values measured before starting maintenance
do not comply with applicable Standards or do not indicate
efficient combustion, consult the table below or contact our
Technical Support Service to implement the necessary
adjustments.
Tab. I
CO
2
It is advisable to adjust the burner with a CO
2
not greater than
about 10% (gas with Ncv 8600 kcal/m
3
).
In this way it is avoided that a small decalibration (for example a
variation in the tension) could cause a combustion with an air
defect and with the subsequent formation of CO.
CO
It should not exceed 100 mg/kWh.
7.2.5 Safety components
The safety components must be replaced at the end of their life
cycle indicated in Tab. J.
The specified life cycles do not refer to the warranty terms
indicated in the delivery or payment conditions.
