9 MAINTENANCE
IMPORTANT
Carry out thorough cleaning and periodic maintenance to ensure a correct and safe operation of the
system. A perfectly clean tube bundle increases the thermal exchange between fumes and water
contributing to energy saving and reducing air pollution.
9.1
PREPARATION FOR INSPECTION AND MAINTENANCE
Before carrying out any kind of maintenance, in order to avoid risks, the operator must be
equipped with all the personal protection provided by the standards in force.
Before performing any cleaning and maintenance operation, it is first necessary to discon-
nect the device from both the fuel and the mains supply.
Maintenance must be entrusted only to
technically qualified personnel
and can be either mechanical or
electrical.
The preparation and status of the generator may be different, depending on the operations to be performed:

With the boiler running,
to check the integrity of the generator when hot (fume trace seal, water side
gasket seal, flue draught, operation of adjustment and safety accessories),

With switch-off and complete cooling
of the generator, when having to open the front door with inspec-
tion inside the furnace and fume chamber.

With cooling, complete empting and safe shut-off of the generator
towards the system of use, in the
case of water side internal visit.
Particular precautions must be taken to avoid the risk of electric shock since the system on
the generator has accessories powered at 230V and/or at 400V.
Before intervening on the generator, ensure that the connection to the electrical system has
been made according to current standards, also ensuring proper earthing connection to the
system.
