KIT H - HORIZONTAL SPLIT SYSTEM Ø80/80 MADE
OF POLYPROPYLENE, ADJUSTABLE AT 360°.
The two tubes system allows fumes discharge
through the fumes exhaust duct and air intake
from outside.
Suitable only for condensing boilers.
It allows discharging fuel gas and air suctioning
for combustion through two separated ducts.
PLEASE SEE THE MAXIMUM DISCHARGE AND
INTAKE LENGTH IN THE TABLE IN CHAPTER
“TECHNICAL DATA”.
The maximum discharge and intake 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:
curve Ø80 at 90°= 1.5 m
curve Ø80 at 45°= 1.2 m
