WORKING

4.1

COMBUSTION ADJUSTMENT

The application of the burner to the heat generator, adjustment and testing must be carried out observing
the instruction manual of the boiler, including verification of the CO and CO
their temperatures and the average temperature of the water in the generator.
To suit the required appliance output, choose the proper setting of the combustion head, and the air damper
opening.
4.2

COMBUSTION HEAD SETTING,

Setting depends on the output of the burner.
Rotate the setting screw (6) in a clockwise or anti-
clockwise direction until set point marked on the
regulating rod (2) is level with the outside plane of
the head assembly (1).
Figure 8 shows the head regulating rod set on set
point 4.
Example:
The burner is installed in a 210 kW heat genera-
tor. Taking an efficiency level of 90% the burner
should give an output of app. 230 kW with the
regulating rod set at set point 4 as shown in the
diagram.
The diagram is for indication purposes: to assure
good working from the burner we suggest adjust-
ing the combustion head according to the heat
generator.

REMOVING THE HEAD ASSEMBLY

Proceed as follows to remove the head assembly:
Disconnect the connections (3 and 5) and loos-
en the screws (10).
Unscrew and remove the screws (7), pull out
the head assembly support (1) turning it slight-
ly to the right.
Take care not to change the setting position
on the elbow-bracket (2) during dismantling.

REASSEMBLING THE HEAD ASSEMBLY

Follow the above instructions in reverse, returning
the head assembly (1) to its original position.
WARNING
Tighten the screws (7) completely (without
locking them); then lock them with a torque
wrench setting of 3 - 4 Nm.
Check there are no gas leaks from the screws
during these operations.
