ADJUSTMENT BURNER
1 - COMBUSTION HEAD
Two separate adjustments have to be made: air and gas.
These adjustments can be carried out when the burner is still open, during the installation (see page 3 - fixing to the
boiler).
Air setting
Loosen the two screws 1) and move the internal part
of the combustion head 2) so that its rear edge 3) is
coincident with the desired set-point on the plate 4).
Tighten the screws 1).
Gas setting
Loosen the screw 5), move the ring 6) so that the
pointer 7) is coincident with the desired set-point 8).
Tighten the screw 5).
Attention: The set-point number is the same for air
and gas setting and is given by the follow-
ing diagram.
Example: The burner is installed on a boiler of 810 kW, assuming an efficiency of 90% the burner output should be
900 kW. From the diagram it can be seen that the air and gas settings for this rating should be no. 5.
