KIT RAIN – Ø 80 HORIZONTAL POLYPROPYLENE
PIPE. OUTSIDE INSTALLATION
It allows the flue discharge through the exhaust
pipe and the air intake from the environment.
Suitable only for condensing boilers.
It allows the combustion flues discharge through
a polypropylene pipe and the air exhaust directly
from the hole situated on the room sealed chamber
plate protected by a metal net.
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 Ø80 to 90° = 1.5 m
co-axial curve Ø80 to 45° = 1.2 m
