6. MAINTENANCE, INSPECTIONS, AND OPERATIONAL CHECKS
6.1 INSPECTION AND MAINTENANCE
•
The boiler should be serviced regularly, at least once a year, and subjected to a maintenance schedule.
•
The boiler’s performance and all components of the heating system should be reviewed before the heating season.
•
All service and maintenance works should be performed by an Authorised Person. Only original parts should be used
for boiler repairs. At every service and maintenance procedure, the tightness of the gas units and gas installations,
and the correctness of the protective systems should be checked. The X Boiler warranty does not cover the above-
mentioned maintenance and service operations.
6.1.1 Maintenance of the combustion chamber, burner, and
electrode.
The interior of the combustion chamber, burner surface,
and the electrode should be checked by visual inspection: a
contaminated burner and combustion chamber interior may be
cleaned with a plastic brush.
•
visible gaps and deformations on the surface of the burner
qualify the burner as unusable. It should be replaced,
•
clean the electrode with a plastic brush,
•
a deformed electrode should be replaced,
•
check the condition of the electrode’s insulator,
•
a dirty insulator should be cleaned,
•
a visibly damaged insulator should be replaced.
In order to get access to the combustion chamber, burner, and electrode:
•
close the gas valve,
•
unscrew the front part of the combustion chamber,
•
remove the wires from the end of the electrode,
•
remove the cover fixing screw of the flue gas-water heat exchanger,
•
remove the cover of the heat exchanger,
•
once maintenance is complete, assemble in reverse order.
NOTE!
A dirty burner or dirty combustion chamber interior
means that boiler maintenance is required.
NOTE!
The tightening torque for the nuts of the burner door should be 5Nm (+1/0Nm).
Pay attention not to damage the seals:
•
check the tightness of connections.
6.1.2 Cleaning the condensate siphon
The condensate siphon should be inspected at least twice a year. If purging is necessary:
•
unscrew the siphon,
•
clean the siphon of any dirt,
•
reassemble and tighten the siphon.
Check the patency of the siphon (for example, by blowing the tube which drains the condensate). In situations where the
siphon is difficult to clean in the above-mentioned way, it should be removed from the boiler and cleaned with a strong
stream of water. To avoid the possibility of flue gas leakage through the siphon as a result of the condensation of water
vapour in it (flooding), pour a little water to flood the siphon.
