For particular flue gas intake/exhaust pipe installations, it is possible to
use a single splitter fitting. This fitting makes it possible to direct the intake
and exhaust in any direction thanks to its 360° rotation.
This type of pipe makes it possible to discharge the flue gas outside of the
building or to single chimneys. The combustion air intake and exhaust can
be located in different areas. The splitter fitting is fixed directly on the
120
boiler and makes it possible for the combustion air and the exhaust flue
gas to enter/exit from two separate pipes (80 mm).
The 90° elbow makes it possible to connect the boiler to exhaust and
intake pipes, adapting it to different requirements. It can also be used as
an additional elbow in combination with the 45° pipe or elbow.

If discharging to the outdoors, the exhaust pipe must exit at least 18 mm
from the wall, in order to position the aluminium washer and its sealing, to
prevent water infiltration.
Caution
Make sure to correctly fasten the splitter fitting by turning it from
position "0" to position "1" as shown in the figure.
Caution
Guarantee a minimum slope of the flue gas evacuation pipe
towards the boiler of at least 5 cm per metre.
