4. BURNING PHASES
Everything described in the previous chapter, OPERATING PRINCIPLES, is outlined in the cycle
below which is divided in four sections:
A. FIRE UP, yellow colour
The burner checks whether there is flame in the burning chamber, in case of a KEEP FIRE status,
so as to offer the minimum required power to the system. Whatever the status of the burning
chamber may be, the burner will proceed with full ignition of the fuel intensifying the flame until
the threshold of burning phase is reached.
B. BURNING
The power of the burner rises progressively whilst it performs constant checks to all parameters
of the combustion in order to allow the maximum desired thermal performance with utmost
economy.
C. FIRE DOWN
When the water temperature approaches the set threshold then the burner regulates POWER to
achieve balance in the system. Gradually, the reduction in burning will lead the system to KEEP
FIRE or OFF status.
D. KEEP FLAME OR OFF
The burner at this phase is put in stand-by mode either turned off or keeping the flame. In both
cases it can be put back to FIRE UP status.
