Miscellaneous
1) Maximum 15,000 burner starts per year. In order not to exceed the number of
burner starts, observe the information on setting the control unit and burner in
the technical guide or installation instructions. If this value is still however
exceeded, please contact the customer service of the manufacturer.
2) The number of burner starts per year is influenced by the boiler system's
operating settings (control parameters in the boiler control and the combustion
setting) and by the design of the boiler system with regard to the consumer's
heat requirement. To avoid exceeding the number of burner starts per year as a
result of operating settings that have not been optimised, the manufacturer
offers complete commissioning and regular system inspections for boilers,
burners and boiler controls (CFB/CC controllers with function modules).
Table 7 Operation conditions
It must be possible to check the number of burner starts, e.g. at the user
interface, third-party control unit, building control system or burner
control unit.
