Combustion Head Adjustment - Riello RS 68/EV ULX Installation, Use And Maintenance Instructions

4.10

Combustion head adjustment

At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 18 on page 22. It is therefore especially
easy to adjust, and this adjustment depends only on the maxi-
mum output of the burner.
Turn the screw 1) (Fig. 22) until the notch matches with the front
plane 2) of the flange.
The combustion head is opened by turning the screw 1) counter-
clockwise.
The combustion head is closed by turning the screw 1) clockwise
(Fig. 24 on page 25).
The burner leaves the factory with the combu-
stion head set to notch 0.
WARNING
This adjustment allows to secure the moving parts during the
transport of the burner.
Before the burner start-up, make the adjustments according to
the required output and indicated in the diagram (Fig. 23).
NOTE:
The adjustment can be changed according to the specific
application.
