All boiler and burner servicing work
should be carried out by an
appropriately trained heating service
specialist. In order to ensure that the
unit is serviced according to the
maintenance schedule, users are
recommended to enter into a
maintenance contract.
Important
Always shut off the power supply
before carrying out maintenance work
or cleaning tasks.
Checking the exhaust gas
temperature
·
Carry out regular checks to
determine exhaust gas temperature.
·
The boiler must be cleaned whenever
the exhaust gas temperature
exceeds the startup setting by more
than 30K.
·
Fit an exhaust gas temperature
indicator to simplify this checking
procedure.
