6.5.3 Separate flue/air ducts
A single flue/air duct connector, or splitting connector,
can be used for special installations. This accessory,
in fact, can be used to move the inlet and outlet in any
120
77,5 120
direction as it can turn 360°. This type of duct makes it
possible to discharge exhaust fumes both outside the
building and into single flue ducts. Comburent air can
be drawn in at a different location from that of the flue
terminal. The separate flue/air duct kit is fixed to the
boiler and allows the comburent air and exhaust fumes
395 279
to enter/leave the two separate ducts (80 mm).
The 90° bend is used to connect the boiler to the inlet
and outlet ducts, adapting them to various requirements.

It can also be used as a supplementary curve combined
with a duct or a 45° bend.
INSTALLING THE FLUE/AIR CONNECTOR
Position the connector as shown in the figure and turn it clockwise to secure it on the boiler.
