To preserve the combustion side open the door and the smoke box doors, clean thoroughly all
surfaces removing all the soot (which may contain sulphur which turn into sulphuric acid when wet)
and add highly hygroscopic substances (ex. caustic lime) in the furnace and smoke box.
Close and seal the door and the cleaning doors.
MAINTENANCE
Periodical maintenance is essential for the safety, efficiency and long life of the equipment.
It is also required by law and must be carried out by professionally qualified personnel.
Before carrying out any work, you are advised to perform a combustion analysis to ascertain the
operating conditions and obtain any other useful information.
After performing the combustion analysis and before any other operation:
-
Wait until the plant is cold;
-
disconnect the electricity supply by switching off the master switch;;
-
close the fuel on-off controls.
Clean the smoke side every 3 months if heavy oil is used, every 6 months with light oil, every year
with gas fuels.
To clean the smoke side open the inspection doors, remove the burner, the plug. W ith a tube -brush,
clean thoroughly all surfaces and the tube bundle to remove soot. Remove all soot from the furnace
and the cleaning doors.
If you believe that the boiler is scaled insi de, empty it and open the hand-hole/manhole; scales
must never be thicker than 0.5 mm. If not, have a chemical washing carried out by qualified
companies and check the softener system.
Warning: replace the hand-hole/manhole gasket each time you open it and t ight gradually in hot and
cold conditions.
CHECKS AFTER BOILER CLEANING
After performing the maintenance and cleaning operations, repeat the preliminary operations prior
to switching on for the first time (see page 15), check the burner setting and perform a fume
analysis.
Check the fuel supply system seal: this check is particularly important when using gaseous fuels .
Check that the fume circuit is perfectly sealed and replace any worn gaskets.
Check the system hydraulic seal to avoid unnecessary exchange of water and topping up which will
increase the risk of scaling.
