3 Product Description
Burner sequencer and fuel/air ratio control can be adjusted for a wide range of combustion
conditions by setting parameters. The BT300 for oil and gas can be set to start with and with-
out pilot burner. The integrated leakage test can be run before ignition or after shutting down
the burner.
Starting without pre-purge using gas is available in accordance with EN676.
The setting of fuel/air ratio curves can be optimised using optional CO/O
2
control during op-
eration. This helps to counteract conditions that interfere with combustion. This ensures a per-
manent burner operation at the greatest possible efficiency.
Operating and fault messages are displayed by symbols and numbers on UI300 User Inter-
face. Plant-specific configurations and settings of fuel/air ratio control curves are operated via
menu of UI300 User Interface.
An operating and start-up counter is integrated.
The optional LCM100 power control unit with two setpoints, external setpoint shift (control by
atmospheric condition) and start-up control is also available.
3.2 Life Cycle
The device has a designed lifetime
1
of 250,000 burner start-up cycles, which, under normal
operating conditions in heating mode, correspond to approx. 10 years of usage (starting from
the production date given on the type plate).
This lifetime is based on the endurance tests specified in standard EN230/EN298 and the ta-
ble containing the relevant test documentation as published by the European Association of
Component Manufacturers (Afecor) (www.afecor.org).
The designed lifetime is based on use of the device according to the manufacturer’s basic doc-
umentation. After reaching designed lifetime in terms of number of burner start-up cycles, or
the respective time of usage, the device must be replaced by authorized personnel.
