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 application,
so it is necessary to use a calibration tool to obtain an efficient
combustion result.
