Concentric Flue System - Type AK50
Horizontal concentric flue kit Ø80/125 mm polypropylene inner pipe.
Adjustable through 360°. Discharges exhaust fumes and draws air from atmo sphere.
Suitable for
only. Discharges
exhaust gases and draws combustion air by means of
two concentric ducts. The external Ø125 duct draws the
combustion air while the Ø80 plastic inner duct
discharges the exhaust fumes.
The discharge duct can be terminated directly to the
outside or can be connected to a suitable plume
management system.
MAXIMUM FLUE LENGTH: RK 18 OV - 12 m
RK 25 OV - 10 m
The maximum flue length (linear equivalent) is
obtained by totalling 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 from the connection with the
combustion chamber of the appliance, excluding the
first bend.
The linear equivalent of additional bends is as
follows:
Ø 80/125 x 90° bend = 1.6 m.
Ø 80/125 x 45° bend = 0.9 m.
N.B.: USE ONLY RADIANT TYPE-APPROVED FLUE
SYSTEMS FOR DISCHARGING EXHAUST GASES
AND DRAWING COMBUSTION AIR.
