5.1
Maintenance schedule
Maintenance operations include check and cleaning procedures. In particular:
Inspections and checks
•
check general integrity of the boiler;
•
check boiler and network gas supply for leakage;
•
check gas supply pressure to boiler;
•
check minimum and maximum gas pressures to boiler nozzles;
•
check boiler ignition sequence;
•
check the condition and seal integrity of the lue gas venting pipes;
•
check operation of safety thermostat installed on the lue gas hood;
•
check boiler combustion parameters by lue gas analysis;
•
check fan hall sensor operation;
•
check integrity of safety devices of the boiler in general;
•
check for water leaks and oxidised areas on the boiler’s couplings;
•
check eiciency of the system safety valves;
•
check CH and DHW expansion vessel illing pressure;
•
check water heater magnesium anode integrity;
•
check correct draining of condensate from the condensate trap installed on the boiler;
Solar plant checks
•
check solar plant pressure and top up luid if necessary;
•
check solar plant low rate;
•
check solar expansion vessel illing pressure.
WARNING
If a solar plant fluid top-up is required, use the same product that was used for filling. Do not dilute the original fluid with water or
with other fluids for any reason, because this may significantly alter the fluid's heat exchange capability and its resistance to high
and low temperatures.
The following cleaning is to be done
•
Clean the general interior of the boiler.
•
Clean the gas nozzles.
•
Clean the air intake and lue gas venting circuits.
•
Clean the heat exchanger.
•
