INSPECTION AND

MAINTENANCE

4.1 - GENERAL RULES FOR RUNNING 

STEAM GENERATORS

The yield and duration of a steam generator 

depend not only on a proper installation but 

also on good operation and maintenance.

Routine maintenance is essential in the in-

terest of the safety, efficiency and durability 

of the appliance. 

All maintenance must be carried out by qual-

ified personnel. 

Failure to perform Inspections and Main-

tenance can entail material and personal 

damage. 

All cleaning and maintenance operations 

must be preceded by closing the fuel sup-

ply, after having disconnected electricity. 

To ensure correct functioning and maxi-

mum  efficiency  of  the  boiler,  you  should 

properly clean the combustion chamber, 

smoke pipes and smoke chamber: on av-

erage every 3 months for combustion with 

dense naphtha, every 6 months if using die-

sel oil and once a year with the use of gas-

eous fuels.

Therefore, observe the following guidelines:

- Periodically check the proper operation and integrity of the 

seals of the fumes evacuation pipe; if you need to perform 

work or maintenance of structures located near the fume 

ducts and any accessories, stop the generator.

- When work has been completed and before restarting the gen-

erator, you must check with the intervention of a specialised 

technician the efficiency of the smoke ducts, chimney and 

in general all the components of the fume extraction circuit.

- At every start, after a period of inactivity, it is necessary to re-

peat the previously described start-up procedures.

- Periodically check the efficiency of the control and safety de

-

vices of the generator.

- Immediately remove any unburned gas leaks by replacing the 

worn seal gaskets.

- Periodically check (at least once a year) the parameters of 

combustion.

- It is forbidden because dangerous, even 

partially obstruct the air vents for the cor-

rect ventilation of the boiler room.

- It is absolutely forbidden to touch the hot 

parts of the generator which are heated 

and therefore burn. The same caution 

should also be used for at least the next 

hour to turn off of the burner.

NOTE

It will be the maintainer's responsibility to 

keep the control unit handbook updated, re-

cording each visit with the date and the type 

of intervention performed.

- All the operations must be performed with the burner stopped 

and the generator "cold";

- in order to avoid any start-up, even accidental, it is advisable to 

remove the fuses of the electrical power line and signal with a 

sign the prohibition to actuate the switch;

- if maintenance is performed by several people, agree before 

starting work "who does what";

- close the fuel supply pipe;

- during cleaning wear all PPE provided for specific activities, in 

strict accordance with the Safety Standards;

- carefully protect all equipment;

- for cleaning, use brushes and vacuum cleaners;

- when necessary to reassemble the components removed for 

cleaning, carefully check the state of the gaskets and / or pro-

vide for their replacement;

- protect screws and nuts with graphite grease which will facili-

tate their subsequent removal;

- after having set up the generator for a long period of inactivity, 

provide appropriate instructions to be placed on the gener-

ator for the operations to be performed before restarting it.

- At the restart, before turning on the burner, check the operation 

of the generator pumps and of the system.
