Flue gas separator adjustment. For correct
functioning of the boiler it is necessary to regu-
late the flue gas shutter positioned on the air/flue
gas sample points (Fig. 1-11).
Adjustment is carried out by loosening the
front retainer screw and moving the indicator
to the correct position, aligning its value to the
horizontal reference. Once adjustment has been
performed, tighten the screw to fix the separator.
The appropriate adjustment is chosen based on
type of pipe and its extension: this calculation
can be made using specific tables.
Intake diaphragm installation. For correct
boiler functioning with Ø 80 separator kits and
drain measuring > 1 m a diaphragm must be
installed on the sealed chamber intake hole and
before the intake pipe (Fig. 1-12). The appropriate
diaphragm is chosen based on type of pipe and
its maximum extension: this calculation can be
made using the tables below:
N.B.: the diaphragms are supplied together with
the boiler as standard.
