AIR REGULATION ON THE COMBUSTION HEAD
The combustion head has a regulation device that allows the air
passage between the disc and the combustion head to be opened
or closed.
You are thus able to obtain, closing the passage, high pressure
upstream of the disk even at 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.
High air pressure upstream of the disk may be necessary to prevent
flame fluctuations, this is particularly essential when the burner works
on the furnace that is pressurised and/or at a high thermal load.
Therefore, the air regulation device on the combustion head should
be put in such a position as to always obtain a decidedly high air
pressure value behind the disk.
Correct the position of the device that closes the air of the combustion
head, moving it forward or backward, in order to obtain an air flow
suitable for the supply with the air damper considerably open.
When reducing the air passage on the combustion head, make sure
not to close it completely.
Centre the combustion head perfectly with respect to the disk.
Finally, fully tighten the screws that anchor the air regulation device
on the combustion head.
Check that the ignition occurs correctly. If the head opens excessively,
it could cause strong air turbulence leading to difficult ignition.

TBG 35 ME 3 ÷ 31 0 ÷ 6
X = Head-disc distance; adjust distance X following the instructions:
• Loosen the screw -10,
• Turn the screw -11 to position the combustion head -16 taking as
reference the index -15.
• adjust the distance X between the minimum and maximum value
according to the indications in the table.
DANGER / CAUTION
The adjustments are indicative; position the combustion head
according to the characteristics of the combustion chamber.
