COMBUSTION HEAD ADJUSTMENT
Loosen the screw (A), move the elbow (B) so that
the rear plate of the coupling (C) coincides with the
set point.
Tighten the screw (A).
Example:
The burner is installed in a 40 kW boiler.
Considering efficiency of 90% the burner must
supply around 44 kW.
The diagram shows that for this
output the adjustment must be
made on notch 3.
The diagram is to be used only
for initial settings, to improve air
pressure

operation
improve combustion, it may be
necessary to reduce this setting
(set point toward position 0).
AIR DAMPER ADJUSTMENT
The air damper opening motor (1) controls the damper
(6); the burner does not start until the damper (6) is com-
pletely open.
To adjust the fixed damper (4) it is necessary to:
loosen the screws (3 and 5) and rotate the damper as
far as the required point (2).
Once optimum adjustment has been reached, fix the
screws (3 and 5).
The adjustment of the damper varies in each single appli-
cation, so it is necessary to use a calibration tool to obtain
an efficient combustion result.
Important:
It is advisable to carry out an analysis of the combustion
values with the hood assembled.
