Maintenance
Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
Combustion
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. N
7.2.4 Combustion control (gas)
CO
2
It is advisable to adjust the burner with a CO
2
not greater than
about 10% (gas with Ncv 8600 kcal/m3). 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 should be replaced at the end of their life
cycle indicated in the following table.
The specified life cycles do not refer to the warranty terms
indicated in the delivery or payment conditions.
