3) Multi-directional 90° bends Ø80 M.F.

6) Taps for flue/air analysis.
Specific outlet needs may be resolved by placing two separate pipes ø 80 mm, one for air
inlet and one for flue outlet up to a total length of the two pipes of m. 40.
This allows an increased installation flexibility, beside a differential orientation in any
direction. When having to cross rooms which are usually heated, the air duct may cause
condense accumulation, therefore a suitable insulation can be applied on demand.
When having to cross
walls or barriers which
could deteriorate due to
the heat, the flue terminal
must be installed with a
suitable isolating sleeve.
The air inlet and flue outlet
ducts will be installed with
a slight downward slant to
avoid rainwater from
entering the boiler.
Perform assembly
according to the
indications in the diagram
and make sure that each
catch is equipped with a
gasket. The length of the
air inlet and of the flue
ducts can be different.
They can be shortened or
lengthened by means of
0.5 m.
