SYSTEMS
KIT K - HORIZONTAL CO-AXIAL SYSTEM Ø60/100
INTERNAL POLYPROPYLENE DUCT ADJUSTABLE
AT 360°.
It allows fumes discharge and air intake from
external wall.
Suitable only for condensing boilers.
It allows fuel gas discharge and air intake for
combustion through co-axial ducts, the external
one for air intake, the plastic internal one for
fumes discharge.
PLEASE SEE THE MAXIMUM DISCHARGE LENGTH
IN THE TABLE IN CHAPTER “TECHNICAL DATA”.
The maximum discharge length (or linear
reference length) can be calculated summing the
length of the linear tube and that equivalent to
each additional curve with respect to the first.
Subsequent addition of a curve is similar to adding
a linear length of tube according to the indications
below:
co-axial curve Ø60/100 at 90° = 1 m
co-axial curve Ø60/100 at 45° = 0.6 m
