Secondary air
This is the air volume passed between
the diameter of the turbulator and the
blast tube. The position of the turbulator
(dimension Y) is to be read on a scale
of the RTC system (retention of the
burner head position) from 0 to 50 mm,
with 50 mm being the biggest and 0 the
smallest secondary air supply. When
the device is supplied, dimension Y is
set to 20 or 30 mm (see table).
Depending on:
Ignition quality (thrusts, fluctuations),
–
Combustion hygiene
–
this value can be adjusted.
–
Setting
This is done during operation or idle
mode, in accordance with the specified
values, without removing the burner.
If dimension Y is reduced, the CO
value increases and vice versa.
