The boiler needs no particular maintenance. Just clean it once a year. Never use chemical products or
steel brushes to clean the casing or the burner.
Particular care must be taken of all retention systems pertaining to the hermetic chamber (seals, cable
clamps, etc.). This will prevent air leaks which, causing a pressure drop in the chamber itself, could activate
the differential pressure switch which would block the boiler.
After all these operations have been carried out, particular care must also be taken to check
and carry out all ignition and operation phases of the thermostats, gas valve and circulation
pump.
Check that there are no gas leaks after these inspections.
