AIR PRESSURE SWITCH
Regulate the air pressure switch after first carrying out all the other
burner adjustments with the air pressure switch adjusted to the start
of the scale.
With the burner operating at the requested power level, slowly turn
the adjustment knob clockwise until the burner locks out.
Then give the screw 1/4 turn anti-clockwise and repeat burner
ignition to check for proper operation.
If the burner locks out again, turn the knob anti-clockwise.
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 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. 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.
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.
When the burner operates at maximum delivery, adjust the head air
closure, in such a way as to require a considerable air flow damper
opening. Therefore start the regulation with the device that closes
the air on the combustion head in an intermediate position, igniting
the burner for an indicative regulation as explained above. Move
the combustion head forward or backward so as to have an air flow
suitable for the delivery.
When the maximum required supply is reached, correct the position
of the device closing the air on the combustion head by moving it
forwards or backwards so as to have a suitable air flow for the supply,
with suction air adjustment damper considerably open.
