• Check pressure and tightness.
Cleaning the cover
• Do not use abrasive products or
products containing chlorine.
• Clean the cover with water and a
suitable cleaning product.
• Refit the cover.
Important
After every operation: check the
combustion parameters and real
operating condition (doors closed,
cover fitted etc.). Record the results
in the relevant documents.
Checking the flue gas temperature
• Check the flue gas temperature at
regular intervals.
• Clean the boiler if the flue gas
temperature is more than 30 °C above
the value measured at the time of
commissioning.
• Use a flue gas temperature gauge to
make the check easier.
Resetting the maintenance indicator
The maintenance symbol
appears on the control unit display after
30,000 start-ups. This is why it is
necessary to reset the maintenance
counter after each service. To do this,
press the control unit unlocking button
for at least 9 seconds.
