3.8 — Normal Operation
In automatic operation, the operating cycle always proceeds sequentially through pre-purge, main flame ignition, run,
and post-purge. The length of the purge and ignition trial vary according to the type of programmer used.
During the run cycle, burner input is regulated to the load demand by the modulating pressure or temperature control on
the boiler. The burner will continue to modulate until the operating pressure or temperature is reached.
Programmer control operation should be tested when the burner is initially placed into service, when a control is
replaced, and at scheduled intervals in the maintenance program.
Refer to adjustment procedures and maintenance instruction given in Chapters 4 and 5.
