1 .1 .2 Stage-controlled main burner with
permanent pilot burner
Control:
Main burner ON/OFF or High/Low
The main burner can be started with
reduced capacity after the operat-
ing signal from the pilot burner has
been detected. Pilot and main burn-
ers can be operated simultaneously.
This reduces the time required by
the main burner for starting up.
The BCU provides the cooling and
purging processes.
