To ensure the correct rated heat input to the maximum and minimum heat input, it is necessary to
update the speed (rpm) of the fan, it depends on the lenght of the pipes (par. 12), in accordance with
the installation of flue and air pipes as indicated in the tables below. The factory-set value is referred
to the minimum length of flue pipe (0÷4 m for concentric, 0÷20 m for twin). To carry such updating,
changing the speed of the fan (rpm) at the maximum and minimum heat input, refer to par. 15.
