Flue type -
kit H
Separate air intake/exhaust fumes discharge system in PPS polypropylene adjustable through 360°.
The
dual pipe system discharges exhaust fumes into a chimney and draws air from atmosphere.
Suitable for
condensing boilers
only.
Discharges exhaust gases and draws
combustion air through two separate Ø
80 ducts.
MAXIMUM FLUE LENGTH:
Ø 80/80: 50 m.
The
maximum
flue length (linear
equivalent) is obtained by summing
the length of linear pipe and the
equivalent lengths of each bend
fitted.
The
linear equivalent
is intended as
being the total length of the duct
(exhaust dis air intake) from
the connection with the combustion
chamber of the appliance, excluding the
first bend.
The addition of a bend has the effect
of increasing the linear equivalent
length of the duct as follows:
Ø 80 x 90° bend = 1.5 m.
Ø 80 x 45° bend = 1.2 m.
N.B.
:
USE ONLY RADIANT TYPE-
APPROVED FLUE SYSTEMS FOR
DISCHARGING EXHAUST GASES AND
DRAWING COMBUSTION AIR.
