5 MAINTENANCE
5.1 ORDINARY
• Periodically purge the level gauges, probe holder if fitted and the boiler, to avoid the accumulation of
sludge;
• Check the efficiency of the control and regulation instruments, examining carefully the electrical parts
(connections included) and the mechanical parts (pressure switches); it is advisable to replace every
year the ceramic probe-holders;
• Carry out burner maintenance (as to the specific instructions);
• Check the tightness of flange bolts and the state of the gaskets;
• Check the conditions of the boiler door internal covering;
• Clean the flue-gas tube bundle and the turbolators;
• Carry out correct maintenance to the pump (bearings, mechanical seal),
• Check for wear to the discharge valves; these tend to wear more quickly, due to the abrasive effect of
the sludge during blow-down.
5.2 PERIODIC
5.2.1 Periodic control (every 6 hours of use)

the efficiency of all safety accessories:
•
