C
1) - Loosen clamping ring nut 2
2) - Increase or decrease the air flow rate through the adjusting ring nut 1 (Clockwise to increase, counter-
clockwise to decrease).
3) - Tighten clamping ring nut 2.
4) - Switch manually from Low flame to High flame and check the combustion values.
All burners are factory tested at 400V - 50Hz 3-phase for motors, and 230V - 50Hz single phase with neutral
for auxiliary equipments. Should it be necessary to power the burner with 230V - 50Hz, modify the connec-
tions on motor and the terminal board as shown in the picture. Protect the burner supply line with suitable
fuses and/or other safety devices as required by the local regulations on the matter.
Air flow rate adjustment in Low flame running:
1) - Start the burner (checking that the air damper is partially
open).
2) - Loosen clamping screw D.
3) - Turn air damper C until obtaining a correct combustion
(checked with a combustion gas analysis set).
+ –
4) - Tighten clamping screw D.
Air flow rate adjustment in High flame running:
WARNING: due to the presence of oil under pressure in the
hydraulic jack when the burner is working in High flame con-
dition, the air flow rate adjustment is to be made with the use
of an adjusting ring nut 1 with the burner running in Low
D
flame condition. The combustion checks are to be done once
the burner is turned to High flame condition again.
