About the appliance
Inspection and service
▶ Recommendation for customers: Arrange a service and inspection
contract with the service department of the manufacturer or with an
authorised contractor, covering an annual inspection and demand-
dependent service.
▶ The user is responsible for the general and environmental safety of
the heating system.
▶ Immediately correct all faults to prevent system damage!
▶ Use only genuine spare parts from the manufacturer. Losses caused
by the use of spare parts and accessories not supplied by the
manufacturer are excluded from the manufacturer's warranty.
Explosive and highly flammable material
▶ Never use or store highly flammable materials (paper, thinners, paints
etc.) near the boiler.
Combustion/room air

Table 3 Operating conditions
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 exceeded, however,
please contact the manufacturer's service department.
2) The number of burner starts per year is affected by the boiler system's operating
settings (controller parameters in the boiler controller and combustion setting)
and sizing to correspond with the consumers' heat demand. To avoid exceeding
the number of annual burner starts as a result of operating settings which have not
been optimised, the manufacturer offers a complete commissioning and regular
document inspections for floor standing residential conventional boilers, burners
and boiler controller (Logamatic control units with function modules).
