Concentric Flue System- Type K
Horizontal concentric flue kit Ø60/100 mm polypropylene inner pipe.
Adjustable through 360°.Discharges exhaust fumes an d draws air from atmosphere.
Suitable for condensing boilers only. Discharges
exhaust gases and draws combustion air by means
of two concentric ducts. The external Ø100 duct
draws the combustion air while the Ø60 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:
RKR 24 - 6 m
RKR 28 - 6 m
RKR 34 - 3 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 60/100 x 90° bend = 0.8 m.
Ø 60/100 x 45° bend = 0.5 m.
