AIR REGULATION ON THE COMBUSTION HEAD
The combustion head is equipped with a regulation device that
makes it possible to open or close the air passage between the
disk and the head.
Closing the air passage increases the pressure upstream of the
disk also with low flow rates.
The high speed and turbulence of the air provides for its greater
penetration into the fuel and therefore an excellent mixture and
flame stability.
It may be necessary to have high air pressure upstream of the
disc, so as to prevent flame pulses. This condition is indispensable
when the burner operates on pressurised combustion chamber
and/or with high heating load.
The combustion head closing device must be set to a position in
which, behind the disc, there is always a very high air pressure
value.
Provide an air closure on the head that requires a noticeable
opening of the air lock that regulates the burner fan intake flow.
Obviously this condition must occur when the burner operates at
the maximum required output.
Start by adjusting the device that closes the air on the combustion
head to an intermediate position, turning on the burner for a
preliminary adjustment as described above.
When the required maximum supply has been reached, the
position of the device that closes the air at the combustion head
has to be corrected, moving it forward or backward, in order to
obtain an air flow suitable for the supply with the air damper
considerably open.
X = Head-disk distance; adjust distance X following the

• loosen the screws (10),
•
turn screw (11) to position the combustion head (16) referring
to index (15).
•
adjust the distance X between the minimum and maximum
value, according to what is indicated in the table.
DANGER / ATTENTION
The adjustments are indicative only; position the combustion
head according to the characteristics of the combustion
chamber.
