The maximum overall length of the
intake and exhaust ducts depends on
the head losses of the single fittings
installed and must not be greater than
7.6 mm H

2.9.1 Separate flue kit (fig. 9)
The separate flue kit code 8089904 is
supplied with an intake diaphragm which
must be used as shown in fig. 9/a, depen-
ding on the maximum load loss permitted
in both flues. To use the air intake in this
type of outlet you must perform the fol-
lowing operations (fig. 10):
–Remove the base of the air intake, using
a tool to cut it off (a);
