	Modulating-controlled forced draught burner The BCU 370 controls the blower and moves the butterfly valve to pre-purging and ignition position. It issues the Enable signal to the control system after start-up of the burner.
	Modulating-controlled forced draught burner with tightness control In addition to controlling the forced draught burner, the burner control unit also monitors the fail-safe function of the two solenoid valves for gas via the DG gas pressure switch.
	Modulating-controlled forced draught burner with pilot burner and tightness control A pilot burner ignites the main burner and is switched off during the main burner’s safety time.
