Flue type - kit CK50
Vertical concentric flue kit Ø80/125 polypropylene inner pipe
.
Discharges exhaust fumes and draws air directly from high Level.
Suitable for
condensing boilers
only.
Discharges exhaust gases and draws combustion air at roof level by means
of two concentric ducts. The external Ø125 duct draws the combustion air
while the Ø80 plastic inner duct discharges the exhaust fumes.
MAXIMUM FLUE LENGTH: 8 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 from
the connection with the combustion chamber of the appliance, excluding
the first bend.
The linear equivalent of additional bends is as follows:
Ø80/ 125 x 90° = 0.8 m.
Ø80/125 x 45° = 0.5 m.
N.B.
:
USE ONLY RADIANT TYPE-APPROVED FLUE SYSTEMS FOR
DISCHARGING EXHAUST GASES AND DRAWING COMBUSTION AIR.
